### Data Binding
### Dynamic Props
Any prop value can be data-driven using expressions:
```json
{
"type": "Metric",
"type": "Icon",
"props": {
"label": "Revenue",
"value": "{{data.revenue}}"
"name": { "$cond": { "eq": [{ "path": "/activeTab" }, "home"] }, "$then": "home", "$else": "home-outline" },
"color": { "$cond": { "eq": [{ "path": "/activeTab" }, "home"] }, "$then": "#007AFF", "$else": "#8E8E93" }
}
}
```
Two expression forms:
- **`{ "$path": "/state/key" }`** -- reads a value from the data model
- **`{ "$cond": <condition>, "$then": <value>, "$else": <value> }`** -- evaluates a condition (same syntax as visibility conditions) and picks a branch
### Actions
Components can trigger actions, including the built-in `setState` action:
```json
{
"type": "Pressable",
"props": { "action": "setState", "actionParams": { "path": "/activeTab", "value": "home" } },
"children": ["home-icon"]
}
```
The `setState` action updates the data model directly, which re-evaluates visibility conditions and dynamic prop expressions.

## Adaptive Cards Overview
Adaptive Cards is a JSON-based format for platform-agnostic UI snippets. Cards have a `body` array of elements and an optional `actions` array for interactive buttons.
### Example Adaptive Card
```json
{
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"type": "AdaptiveCard",
"version": "1.5",
"body": [
{
"type": "TextBlock",
"text": "Hello, Adaptive Cards!",
"size": "large",
"weight": "bolder"
},
{
"type": "Image",
"url": "https://example.com/image.png",
"altText": "Example image"
},
{
"type": "Container",
"items": [
{
"type": "TextBlock",
"text": "This is inside a container",
"wrap": true
}
]
},
{
"type": "ColumnSet",
"columns": [
{
"type": "Column",
"width": "auto",
"items": [
{ "type": "TextBlock", "text": "Column 1" }
]
},
{
"type": "Column",
"width": "stretch",
"items": [
{ "type": "TextBlock", "text": "Column 2" }
]
}
]
},
{
"type": "Input.Text",
"id": "userInput",
"placeholder": "Enter your name",
"label": "Name"
}
],
"actions": [
{
"type": "Action.Submit",
"title": "Submit"
},
{
"type": "Action.OpenUrl",
"title": "Learn More",

}
]
}
```
## Creating an Adaptive Cards Catalog
Define a catalog matching the Adaptive Cards element types:
```typescript
import { createCatalog } from '@json-render/core';

// Common Adaptive Cards properties
const Spacing = z.enum(['none', 'small', 'default', 'medium', 'large', 'extraLarge', 'padding']);
const HorizontalAlignment = z.enum(['left', 'center', 'right']);
const VerticalAlignment = z.enum(['top', 'center', 'bottom']);
const FontSize = z.enum(['small', 'default', 'medium', 'large', 'extraLarge']);
const FontWeight = z.enum(['lighter', 'default', 'bolder']);
const ImageSize = z.enum(['auto', 'stretch', 'small', 'medium', 'large']);
const ImageStyle = z.enum(['default', 'person']);
// Base element properties shared by most elements
const BaseElement = {
id: z.string().optional(),
isVisible: z.boolean().optional(),

};

## Building an Adaptive Cards Renderer
Create a renderer that processes Adaptive Cards JSON. See the [A2UI integration](/docs/a2ui) page for a similar pattern. The key is mapping each Adaptive Card element type to a React component, resolving nested `items` and `columns` arrays recursively.
## Usage Example
Render an Adaptive Card and handle actions:
```tsx
'use client';
import { AdaptiveCardRenderer } from './adaptive-card-renderer';
const card = {
type: 'AdaptiveCard' as const,
version: '1.5',
body: [
{
type: 'TextBlock',
text: 'Contact Form',
size: 'large',
weight: 'bolder',
},
{
type: 'Input.Text',
id: 'name',
label: 'Your Name',
placeholder: 'Enter your name',
},
{
type: 'Input.Text',
id: 'message',
label: 'Message',
placeholder: 'Enter your message',
isMultiline: true,
},
],
actions: [
{
type: 'Action.Submit',
title: 'Send',
data: { action: 'submitForm' },
},
],
};
export function ContactCard() {
const handleAction = (action: any, inputData: Record<string, unknown>) => {
console.log('Action:', action);
console.log('Input data:', inputData);
// Send to your backend
fetch('/api/submit', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ action, data: inputData }),
});
};
return <AdaptiveCardRenderer card={card} onAction={handleAction} />;
}
```
## Handling Action.Execute for Bots
For bot scenarios, handle `Action.Execute` with the verb and data:
```typescript
interface ActionExecutePayload {
action: {
type: 'Action.Execute';
verb: string;
data?: unknown;
};
inputs: Record<string, unknown>;
}
async function handleBotAction(payload: ActionExecutePayload) {
const response = await fetch('/api/bot/action', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
verb: payload.action.verb,
data: payload.action.data,
inputs: payload.inputs,
}),
});
// Bot may return a new card to render
const result = await response.json();
if (result.card) {
return result.card; // New AdaptiveCard to render
}
}
```

# AG-UI Integration
Use json-render to support [AG-UI](https://docs.copilotkit.ai/ag-ui) (Agent User Interaction Protocol) from CopilotKit.
<div className="rounded-lg border border-amber-500/50 bg-amber-500/10 p-4 mb-8">
<p className="text-sm text-amber-700 dark:text-amber-300">
<strong>Concept:</strong> This page demonstrates how json-render can support AG-UI. The examples are illustrative and may require adaptation for production use.
</p>
</div>
## What is AG-UI?
AG-UI is an open protocol for connecting AI agents to user interfaces. It provides a standardized way for agents to render UI components, handle user input, and manage state. The protocol uses events streamed over HTTP to update the UI in real-time.
## AG-UI Event Types
AG-UI defines several event types for agent-UI communication:
- `TEXT_MESSAGE_START` / `TEXT_MESSAGE_CONTENT` / `TEXT_MESSAGE_END` — Streaming text messages
- `TOOL_CALL_START` / `TOOL_CALL_ARGS` / `TOOL_CALL_END` — Tool/function calls
- `STATE_SNAPSHOT` / `STATE_DELTA` — State updates
- `CUSTOM` — Custom events for UI rendering
### Example AG-UI Event Stream
```json
{"type": "RUN_STARTED", "threadId": "thread-123", "runId": "run-456"}
{"type": "TEXT_MESSAGE_START", "messageId": "msg-1", "role": "assistant"}
{"type": "TEXT_MESSAGE_CONTENT", "messageId": "msg-1", "delta": "Here's a dashboard for you:"}
{"type": "TEXT_MESSAGE_END", "messageId": "msg-1"}
{"type": "TOOL_CALL_START", "toolCallId": "tc-1", "toolCallName": "render_ui"}
{"type": "TOOL_CALL_ARGS", "toolCallId": "tc-1", "delta": "{\"component\": \"Dashboard\", \"props\": {\"title\": \"Sales\"}}"}
{"type": "TOOL_CALL_END", "toolCallId": "tc-1"}
{"type": "RUN_FINISHED"}
```
## Define the AG-UI Schema
Define schemas for AG-UI event types:
```typescript
import { z } from 'zod';
// Base event schema
const BaseEvent = z.object({
type: z.string(),
timestamp: z.number().optional(),
});
// Text message events
const TextMessageStart = BaseEvent.extend({
type: z.literal('TEXT_MESSAGE_START'),
messageId: z.string(),
role: z.enum(['user', 'assistant']),
});
const TextMessageContent = BaseEvent.extend({
type: z.literal('TEXT_MESSAGE_CONTENT'),
messageId: z.string(),
delta: z.string(),
});
const TextMessageEnd = BaseEvent.extend({
type: z.literal('TEXT_MESSAGE_END'),
messageId: z.string(),
});
// Tool call events
const ToolCallStart = BaseEvent.extend({
type: z.literal('TOOL_CALL_START'),
toolCallId: z.string(),
toolCallName: z.string(),
parentMessageId: z.string().optional(),
});
const ToolCallArgs = BaseEvent.extend({
type: z.literal('TOOL_CALL_ARGS'),
toolCallId: z.string(),
delta: z.string(),
});
const ToolCallEnd = BaseEvent.extend({
type: z.literal('TOOL_CALL_END'),
toolCallId: z.string(),
});
// State events
const StateSnapshot = BaseEvent.extend({
type: z.literal('STATE_SNAPSHOT'),
snapshot: z.record(z.unknown()),
});
const StateDelta = BaseEvent.extend({
type: z.literal('STATE_DELTA'),
delta: z.array(z.object({
op: z.enum(['add', 'remove', 'replace']),
path: z.string(),
value: z.unknown().optional(),
})),
});
// Custom event for UI components
const CustomEvent = BaseEvent.extend({
type: z.literal('CUSTOM'),
name: z.string(),
value: z.unknown(),
});
// Run lifecycle events
const RunStarted = BaseEvent.extend({
type: z.literal('RUN_STARTED'),
threadId: z.string(),
runId: z.string(),
});
const RunFinished = BaseEvent.extend({
type: z.literal('RUN_FINISHED'),
});
const RunError = BaseEvent.extend({
type: z.literal('RUN_ERROR'),
message: z.string(),
code: z.string().optional(),
});
// Union of all events
export const AGUIEvent = z.discriminatedUnion('type', [
TextMessageStart,
TextMessageContent,
TextMessageEnd,
ToolCallStart,
ToolCallArgs,
ToolCallEnd,
StateSnapshot,
StateDelta,
CustomEvent,
RunStarted,
RunFinished,
RunError,
]);
export type AGUIEvent = z.infer<typeof AGUIEvent>;
```
## Define the AG-UI Catalog
Create a catalog for UI components that agents can render:
```typescript
import { createCatalog } from '@json-render/core';
import { z } from 'zod';
export const aguiCatalog = createCatalog({
components: {
Container: {
description: 'A container for grouping elements',
props: z.object({
direction: z.enum(['row', 'column']).optional(),
gap: z.enum(['none', 'sm', 'md', 'lg']).optional(),
padding: z.enum(['none', 'sm', 'md', 'lg']).optional(),
}),
},
Card: {
description: 'A card with optional title',
props: z.object({
title: z.string().optional(),
description: z.string().optional(),
}),
},
Text: {
description: 'Text content',
props: z.object({
content: z.string(),
variant: z.enum(['body', 'heading', 'caption', 'code']).optional(),
}),
},
Metric: {
description: 'Displays a metric value',
props: z.object({
label: z.string(),
value: z.union([z.string(), z.number()]),
change: z.number().optional(),
format: z.enum(['number', 'currency', 'percent']).optional(),
}),
},
Button: {
description: 'Interactive button',
props: z.object({
label: z.string(),
variant: z.enum(['primary', 'secondary', 'outline', 'ghost']).optional(),
disabled: z.boolean().optional(),
}),
},
Alert: {
description: 'Alert message',
props: z.object({
message: z.string(),
type: z.enum(['info', 'success', 'warning', 'error']).optional(),
}),
},
// Add more components...
},
actions: {
submit: {
description: 'Submit form data',
params: z.object({ formId: z.string() }),
},
navigate: {
description: 'Navigate to a URL',
params: z.object({ url: z.string() }),
},
callback: {
description: 'Trigger a callback to the agent',
params: z.object({
name: z.string(),
data: z.record(z.unknown()).optional(),
}),
},
},
});
```
## Build an AG-UI Event Processor
Process AG-UI events and render UI components:
```tsx
'use client';
import React, { useState, useCallback } from 'react';
import { AGUIEvent } from './schema';
interface AGUIState {
messages: Array<{
id: string;
role: 'user' | 'assistant';
content: string;
}>;
toolCalls: Map<string, {
name: string;
args: string;
result?: unknown;
}>;
state: Record<string, unknown>;
isRunning: boolean;
}
export function useAGUI() {
const [aguiState, setAGUIState] = useState<AGUIState>({
messages: [],
toolCalls: new Map(),
state: {},
isRunning: false,
});
const processEvent = useCallback((event: AGUIEvent) => {
switch (event.type) {
case 'RUN_STARTED':
setAGUIState(prev => ({ ...prev, isRunning: true }));
break;
case 'RUN_FINISHED':
setAGUIState(prev => ({ ...prev, isRunning: false }));
break;
case 'TEXT_MESSAGE_START':
setAGUIState(prev => ({
...prev,
messages: [...prev.messages, {
id: event.messageId,
role: event.role,
content: '',
}],
}));
break;
case 'TEXT_MESSAGE_CONTENT':
setAGUIState(prev => ({
...prev,
messages: prev.messages.map(msg =>
msg.id === event.messageId
? { ...msg, content: msg.content + event.delta }
: msg
),
}));
break;
case 'TOOL_CALL_START':
setAGUIState(prev => {
const toolCalls = new Map(prev.toolCalls);
toolCalls.set(event.toolCallId, { name: event.toolCallName, args: '' });
return { ...prev, toolCalls };
});
break;
case 'TOOL_CALL_ARGS':
setAGUIState(prev => {
const toolCalls = new Map(prev.toolCalls);
const tc = toolCalls.get(event.toolCallId);
if (tc) {
toolCalls.set(event.toolCallId, { ...tc, args: tc.args + event.delta });
}
return { ...prev, toolCalls };
});
break;
case 'STATE_SNAPSHOT':
setAGUIState(prev => ({ ...prev, state: event.snapshot }));
break;
}
}, []);
return { state: aguiState, processEvent };
}
```
## Usage Example
```tsx
'use client';
import { useAGUI } from './use-agui';
import { renderToolCallUI } from './renderer';
export function AGUIChat() {
const { state, processEvent } = useAGUI();
async function startRun(prompt: string) {
const response = await fetch('/api/agent', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ prompt }),
});
const reader = response.body?.getReader();
const decoder = new TextDecoder();
while (reader) {
const { done, value } = await reader.read();
if (done) break;
const lines = decoder.decode(value).split('\n').filter(Boolean);
for (const line of lines) {
const event = JSON.parse(line);
processEvent(event);
}
}
}
return (
<div className="space-y-4">
{state.messages.map(msg => (
<div key={msg.id} className={`p-3 rounded ${
msg.role === 'assistant' ? 'bg-muted' : 'bg-primary/10'
}`}>
{msg.content}

<strong>Concept:</strong> This page demonstrates how json-render can
support AG-UI. The examples are illustrative and may require
adaptation for production use.

<h2 className="text-xl font-semibold mt-12 mb-4">What is AG-UI?</h2>
<p className="text-sm text-muted-foreground mb-4">
AG-UI is an open protocol for connecting AI agents to user interfaces.
It provides a standardized way for agents to render UI components,
handle user input, and manage state. The protocol uses events streamed
over HTTP to update the UI in real-time.
</p>
<h2 className="text-xl font-semibold mt-12 mb-4">AG-UI Event Types</h2>
<p className="text-sm text-muted-foreground mb-4">
AG-UI defines several event types for agent-UI communication:
</p>
<ul className="list-disc list-inside text-sm text-muted-foreground space-y-1 mb-4">
<li>
<code className="text-foreground">TEXT_MESSAGE_START</code> /{" "}
<code className="text-foreground">TEXT_MESSAGE_CONTENT</code> /{" "}
<code className="text-foreground">TEXT_MESSAGE_END</code> — Streaming
text messages
</li>
<li>
<code className="text-foreground">TOOL_CALL_START</code> /{" "}
<code className="text-foreground">TOOL_CALL_ARGS</code> /{" "}
<code className="text-foreground">TOOL_CALL_END</code> — Tool/function
calls
</li>
<li>
<code className="text-foreground">STATE_SNAPSHOT</code> /{" "}
<code className="text-foreground">STATE_DELTA</code> — State updates
</li>
<li>
<code className="text-foreground">CUSTOM</code> — Custom events for UI

# AI SDK Integration
Use json-render with the Vercel AI SDK for seamless streaming.
## Installation
```bash
npm install ai
```
## API Route Setup
```typescript
// app/api/generate/route.ts
import { streamText } from 'ai';
import { catalog } from '@/lib/catalog';
export async function POST(req: Request) {
const { prompt, currentTree } = await req.json();
// Generate system prompt from catalog
const systemPrompt = catalog.prompt();
// Optionally include current UI state for context
const contextPrompt = currentTree
? `\n\nCurrent UI state:\n${JSON.stringify(currentTree, null, 2)}`
: '';
const result = streamText({
model: 'anthropic/claude-haiku-4.5',
system: systemPrompt + contextPrompt,
prompt,
});
return result.toTextStreamResponse();
}
```
## Client-Side Hook
Use `useUIStream` on the client:
```tsx
'use client';
import { useUIStream, Renderer } from '@json-render/react';
function GenerativeUI() {
const { spec, isStreaming, error, send } = useUIStream({
api: '/api/generate',
});
return (
<div>
<button
onClick={() => send('Create a dashboard with metrics')}
disabled={isStreaming}
>
{isStreaming ? 'Generating...' : 'Generate'}
</button>
{error && <p className="text-red-500">{error.message}</p>}
<Renderer spec={spec} registry={registry} loading={isStreaming} />
</div>
);
}
```
## Prompt Engineering
The `catalog.prompt()` method creates an optimized system prompt that:
- Lists all available components and their props
- Describes available actions
- Specifies the expected JSON output format
- Includes examples for better generation
## Custom System Prompts
Pass custom rules to tailor AI behavior:
```typescript
const systemPrompt = catalog.prompt({
customRules: [
'Always use Card components for grouping related content',
'Prefer horizontal layouts (Row) for metrics',
'Use consistent spacing with padding="md"',
],
});
```

export const metadata = { title: "@json-render/codegen API" }
# @json-render/codegen
Utilities for generating code from UI trees.
## Tree Traversal
### traverseSpec
Walk the UI spec depth-first.
```typescript
function traverseSpec(
spec: Spec,
visitor: SpecVisitor,
startKey?: string
): void
interface SpecVisitor {
(element: UIElement, depth: number, parent: UIElement | null): void;
}
```
### collectUsedComponents
Get all unique component types used in a spec.
```typescript
function collectUsedComponents(spec: Spec): Set<string>
// Example
const components = collectUsedComponents(spec);
// Set { 'Card', 'Metric', 'Chart' }
```
### collectStatePaths
Get all state paths referenced in props (statePath, bindPath, valuePath, etc.).
```typescript
function collectStatePaths(spec: Spec): Set<string>
// Example
const paths = collectStatePaths(spec);
// Set { 'analytics/revenue', 'analytics/customers' }
```
### collectActions
Get all action names used in the spec.
```typescript
function collectActions(spec: Spec): Set<string>
// Example
const actions = collectActions(spec);
// Set { 'submit_form', 'refresh_data' }
```
## Serialization
### serializePropValue
Serialize a single value to a code string.
```typescript
function serializePropValue(
value: unknown,
options?: SerializeOptions
): { value: string; needsBraces: boolean }
// Examples
serializePropValue("hello")
// { value: '"hello"', needsBraces: false }
serializePropValue(42)
// { value: '42', needsBraces: true }
serializePropValue({ path: 'user/name' })
// { value: '{ path: "user/name" }', needsBraces: true }
```
### serializeProps
Serialize a props object to a JSX attributes string.
```typescript
function serializeProps(
props: Record<string, unknown>,
options?: SerializeOptions
): string
// Example
serializeProps({ title: 'Dashboard', columns: 3, disabled: true })
// 'title="Dashboard" columns={3} disabled'
```
### escapeString
Escape a string for use in code.
```typescript

# @json-render/core
Core types, schemas, and utilities.
## defineCatalog
Creates a type-safe catalog definition with schema validation.
```typescript
import { defineCatalog } from '@json-render/core';
import { schema } from '@json-render/react';
function defineCatalog<T extends ZodType>(
s: T,
config: CatalogConfig
): Catalog
// Use the React schema for standard UI specs
const catalog = defineCatalog(schema, {
components: {...},
actions: {...},
});
```
### CatalogConfig
```typescript
interface CatalogConfig {
components: Record<string, ComponentDefinition>;
actions?: Record<string, ActionDefinition>;
functions?: Record<string, FunctionDefinition>;
}
interface ComponentDefinition {
props: ZodObject; // Use .nullable() for optional props
slots?: string[]; // Named slots (e.g., ["default"])
description?: string; // Help AI understand usage
}
interface ActionDefinition {
params?: ZodObject;
description?: string;
}
interface FunctionDefinition {
description?: string;
}
```
### Catalog Instance
The returned catalog provides methods for AI prompt generation, validation, and schema export:
```typescript
interface Catalog {
// Data
readonly data: CatalogConfig; // The catalog configuration
readonly componentNames: string[]; // List of component names
readonly actionNames: string[]; // List of action names
// AI Prompt Generation
prompt(options?: PromptOptions): string;
// Validation
validate(spec: unknown): SpecValidationResult;
zodSchema(): z.ZodType; // Get the Zod schema for specs
// Export
jsonSchema(): object; // Export as JSON Schema
}
interface PromptOptions {
system?: string; // Custom system message intro
customRules?: string[]; // Additional rules to append
}
interface SpecValidationResult<T> {
success: boolean;
data?: T; // Validated spec (if success)
error?: z.ZodError; // Validation errors (if failed)
}
```
### Catalog Methods
```typescript
// Generate AI system prompt
const systemPrompt = catalog.prompt({
customRules: ["Always use Card as root element"],
});
// Validate a spec from AI
const result = catalog.validate(aiOutput);
if (result.success) {
render(result.data);
} else {
console.error(result.error);
}
// Get Zod schema for custom validation
const schema = catalog.zodSchema();
const parsed = schema.safeParse(aiOutput);
// Export as JSON Schema (for structured outputs)
const jsonSchema = catalog.jsonSchema();
```
## Schema System
json-render uses a flexible schema system that defines both the AI output format (spec) and what catalogs must provide. Each renderer package provides its own schema (e.g., @json-render/react exports `schema`).
### schema
The schema for flat UI element trees. This is exported from @json-render/react.
```typescript
import { defineCatalog } from '@json-render/core';
import { schema } from '@json-render/react';
// schema defines:
// - Spec shape: { root: string, elements: Record<string, UIElement> }
// - Catalog shape: { components: {...}, actions: {...} }
const catalog = defineCatalog(schema, {
components: {
Card: {
props: z.object({ title: z.string() }),
slots: ["default"],
description: "Container card",
},
},
actions: {
submit: {
params: z.object({ formId: z.string() }),
description: "Submit a form",
},
},
});
```
### defineSchema
Create custom schemas for different output formats (e.g., page-based, block-based).
```typescript
import { defineSchema } from '@json-render/core';
const mySchema = defineSchema((s) => ({
// What the AI outputs (spec)
spec: s.object({
title: s.string(),
blocks: s.array(s.object({
type: s.ref("catalog.blocks"),
content: s.any(),
})),
}),
// What the catalog must provide
catalog: s.object({
blocks: s.map({
props: s.zod(),
description: s.string(),
}),
}),
}));
```
### Schema Builder API
The schema builder provides these methods:
```typescript
// Primitive types
s.string() // String value
s.number() // Number value
s.boolean() // Boolean value
s.any() // Any value
// Compound types
s.array(item) // Array of items
s.object({ ... }) // Object with shape
s.record(value) // Record/map with value type
// Catalog references (for type safety)
s.ref("catalog.components") // Reference to catalog key (becomes enum)
s.propsOf("catalog.components") // Props schema from catalog entry
// Catalog definitions
s.map({ props: s.zod(), ... }) // Map of named entries with shared shape
s.zod() // Placeholder for user-provided Zod schema
// Modifiers
s.optional() // Mark field as optional
```
## Zod Schemas
Pre-built Zod schemas for common json-render types:
### Dynamic Value Schemas
```typescript
import {
DynamicValueSchema, // string | number | boolean | null | { path: string }
DynamicStringSchema, // string | { path: string }
DynamicNumberSchema, // number | { path: string }
DynamicBooleanSchema, // boolean | { path: string }
} from '@json-render/core';
// Dynamic values can be literals or data path references
type DynamicValue<T> = T | { path: string };
// Example: a prop that can be a literal or bound to data
const schema = z.object({
label: DynamicStringSchema, // "Hello" or { path: "/user/name" }
});
```
### Visibility & Logic Schemas
```typescript
import {
VisibilityConditionSchema, // Full visibility condition
LogicExpressionSchema, // Logic operators (and, or, not, eq, gt, etc.)
} from '@json-render/core';
// Use in component props that need conditional rendering
const schema = z.object({
visible: VisibilityConditionSchema.optional(),
});
```
### Action Schemas
```typescript
import {
ActionSchema, // Full action definition
ActionConfirmSchema, // Confirmation dialog config
ActionOnSuccessSchema, // Success handler config
ActionOnErrorSchema, // Error handler config
} from '@json-render/core';
```
### Validation Schemas
```typescript
import {
ValidationCheckSchema, // Single validation check
ValidationConfigSchema, // Full validation config with checks array
} from '@json-render/core';
```
## SpecStream
SpecStream is json-render's streaming format for progressively building specs from JSONL patches.
### createSpecStreamCompiler
Create a streaming compiler that incrementally builds a spec:
```typescript
import { createSpecStreamCompiler } from '@json-render/core';
const compiler = createSpecStreamCompiler<MySpec>();
// Process streaming chunks
const { result, newPatches } = compiler.push(chunk);
// Get final result
const spec = compiler.getResult();
// Reset for reuse
compiler.reset();
```
### compileSpecStream
Compile an entire SpecStream string at once:
```typescript
import { compileSpecStream } from '@json-render/core';
const jsonl = `{"op":"add","path":"/root","value":{}}
{"op":"add","path":"/root/type","value":"Card"}`;
const spec = compileSpecStream<MySpec>(jsonl);
```
### Low-Level Utilities
```typescript
import {
parseSpecStreamLine,
applySpecStreamPatch,
} from '@json-render/core';
// Parse a single line
const patch = parseSpecStreamLine('{"op":"add","path":"/root","value":{}}');
// Apply patch to object (mutates in place)
const obj = {};
applySpecStreamPatch(obj, patch);
```
### SpecStream Types
Fully compliant with [RFC 6902](https://datatracker.ietf.org/doc/html/rfc6902):
```typescript
interface SpecStreamLine {
op: 'add' | 'remove' | 'replace' | 'move' | 'copy' | 'test';
path: string;
value?: unknown; // Required for add, replace, test
from?: string; // Required for move, copy
}
interface SpecStreamCompiler<T> {
push(chunk: string): { result: T; newPatches: SpecStreamLine[] };
getResult(): T;
getPatches(): SpecStreamLine[];
reset(): void;
}
```
## Utility Functions
### Path Utilities
```typescript
import { getByPath, setByPath } from '@json-render/core';
// Get value by JSON Pointer path
const value = getByPath(data, '/user/name'); // "Alice"
// Set value by path (mutates object)
setByPath(data, '/user/email', 'alice@example.com');
```
### resolveDynamicValue
```typescript
import { resolveDynamicValue } from '@json-render/core';
// Resolve a dynamic value against data
const name = resolveDynamicValue("Hello", data); // "Hello"
const name2 = resolveDynamicValue({ path: "/user/name" }, data); // "Alice"
```
### findFormValue
```typescript
import { findFormValue } from '@json-render/core';
// Find form values regardless of path format
// Checks: params.name, params["form.name"], data["form.name"], data.form.name
const value = findFormValue("name", params, data);
```
## evaluateVisibility
Evaluates a visibility condition against data and auth state.
```typescript
function evaluateVisibility(
condition: VisibilityCondition | undefined,
data: Record<string, unknown>,
auth?: AuthState
): boolean
type VisibilityCondition =
| { path: string }
| { auth: 'signedIn' | 'signedOut' | string }
| { and: VisibilityCondition[] }
| { or: VisibilityCondition[] }
| { not: VisibilityCondition }
| { eq: [DynamicValue, DynamicValue] }
| { gt: [DynamicValue, DynamicValue] }
| { gte: [DynamicValue, DynamicValue] }
| { lt: [DynamicValue, DynamicValue] }
| { lte: [DynamicValue, DynamicValue] };
```
## Types
### UIElement
```typescript
interface UIElement {
key: string;
type: string;
props: Record<string, unknown>;
children?: string[]; // Keys of child elements
visible?: VisibilityCondition;
validation?: ValidationSchema;
}
```
### Spec (Element Tree)
```typescript
interface Spec {
root: string | null; // Key of root element
elements: Record<string, UIElement>;
}
```
Elements are stored as a flat map with string keys. The tree structure is built by following the `children` arrays.
### Action
```typescript
interface Action {
name: string;
params?: Record<string, unknown>;
confirm?: {
title: string;
message: string;
variant?: 'default' | 'danger';
};
onSuccess?: { set: Record<string, unknown> };
onError?: { set: Record<string, unknown> };
}
```
### ValidationSchema
```typescript
interface ValidationSchema {
checks: ValidationCheck[];
validateOn?: 'change' | 'blur' | 'submit';
}
interface ValidationCheck {
fn: string;
args?: Record<string, unknown>;
message: string;
}
```

<StateProvider initialState={object}>
{children}
</StateProvider>
```
### ActionProvider
```tsx
<ActionProvider handlers={Record<string, ActionHandler>}>
{children}
</ActionProvider>
type ActionHandler = (params: Record<string, unknown>) => void | Promise<void>;
```

type ValidatorFn = (value: unknown, args?: object) => boolean | Promise<boolean>;
```
## defineRegistry
Create a type-safe component registry from a catalog. Components receive `props`, `children`, `onAction`, and `loading` with catalog-inferred types.
```tsx
import { defineRegistry } from '@json-render/react';
const { registry } = defineRegistry(catalog, {
components: {
Card: ({ props, children }) => <div>{props.title}{children}</div>,
Button: ({ props, onAction }) => (
<button onClick={() => onAction?.({ name: props.action })}>
{props.label}
</button>
),
},
});
// Pass to <Renderer>
<Renderer spec={spec} registry={registry} />
```
## Components
### Renderer
```tsx
<Renderer
spec={Spec} // The UI spec to render
registry={Registry} // Component registry (from defineRegistry)
loading={boolean} // Optional loading state
fallback={Component} // Optional fallback for unknown types
/>
type Registry = Record<string, React.ComponentType<ComponentRenderProps>>;
```
### Component Props (via defineRegistry)
```tsx
interface ComponentContext<P> {
props: P; // Typed props from catalog
children?: React.ReactNode; // Rendered children (for slot components)
onAction?: (action: { name: string; params?: object }) => void;
loading?: boolean;
}
```
## Hooks
### useUIStream
```typescript
const {
spec, // Spec | null - current UI state
isStreaming, // boolean - true while streaming
error, // Error | null
send, // (prompt: string, context?: Record<string, unknown>) => Promise<void>
clear, // () => void - reset spec and error
} = useUIStream({
api: string, // API endpoint URL
onComplete?: (spec: Spec) => void, // Called when streaming completes
onError?: (error: Error) => void, // Called when an error occurs
});
```
### useStateStore
```typescript
const {
data, // Record<string, unknown>
setState, // (data: object) => void
getValue, // (path: string) => unknown
setValue, // (path: string, value: unknown) => void
} = useStateStore();
```
### useStateValue
```typescript
const value = useStateValue(path: string);
```
### useStateBinding
```typescript
const [value, setValue] = useStateBinding(path: string);
```
### useActions
```typescript
const { dispatch } = useActions();
// dispatch(actionName: string, params: object)
```
### useAction
```typescript
const submitForm = useAction('submit_form');
// submitForm(params: object)
```
### useIsVisible
```typescript
const isVisible = useIsVisible(condition?: VisibilityCondition);
```
### useFieldValidation
```typescript
const {
value, // unknown
setValue, // (value: unknown) => void
errors, // string[]
validate, // () => Promise<boolean>
isValid, // boolean
} = useFieldValidation(path: string, checks: ValidationCheck[]);

# @json-render/remotion
Remotion video renderer. Turn JSON timeline specs into video compositions.
## schema
The timeline schema for video specs. Use with `defineCatalog` from core.
```typescript
import { defineCatalog } from '@json-render/core';
import { schema, standardComponentDefinitions } from '@json-render/remotion';
const catalog = defineCatalog(schema, {
components: standardComponentDefinitions,
transitions: standardTransitionDefinitions,
effects: standardEffectDefinitions,
});
```
## Renderer
The main composition component that renders timeline specs. Use with Remotion's Player or in a Remotion project.
```tsx
import { Player } from '@remotion/player';
import { Renderer } from '@json-render/remotion';
function VideoPlayer({ spec }) {
return (
<Player
component={Renderer}
inputProps={{ spec }}
durationInFrames={spec.composition.durationInFrames}
fps={spec.composition.fps}
compositionWidth={spec.composition.width}
compositionHeight={spec.composition.height}
controls
/>
);
}
```
### Custom Components
Pass custom components to the Renderer:
```tsx
import { Renderer, standardComponents } from '@json-render/remotion';
const customComponents = {
...standardComponents,
MyCustomClip: ({ clip }) => <div>{clip.props.text}</div>,
};
<Player
component={Renderer}
inputProps={{ spec, components: customComponents }}
// ...
/>
```
## Standard Components
Pre-built video components included in the package:
```typescript
import {
TitleCard, // Full-screen title with subtitle
ImageSlide, // Full-screen image display
SplitScreen, // Two-column layout
QuoteCard, // Quote with attribution
StatCard, // Large statistic display
LowerThird, // Name/title overlay
TextOverlay, // Centered text overlay
TypingText, // Terminal typing animation
LogoBug, // Corner logo watermark
VideoClip, // Video playback
} from '@json-render/remotion';
```
### TitleCard Props
```typescript
{
title: string;
subtitle?: string;
backgroundColor?: string; // default: "#1a1a1a"
textColor?: string; // default: "#ffffff"
}
```

// Use in your catalog
const catalog = defineCatalog(schema, {
components: {
...standardComponentDefinitions,
// Add custom components
},
transitions: standardTransitionDefinitions,
effects: standardEffectDefinitions,
});
```
## Hooks & Utilities
### useTransition
Calculate transition styles for a clip based on current frame:
```typescript
import { useTransition } from '@json-render/remotion';
import { useCurrentFrame } from 'remotion';
function MyComponent({ clip }) {
const frame = useCurrentFrame();
const transition = useTransition(clip, frame);
return (
<div style={{
opacity: transition.opacity,
transform: transition.transform,
}}>
Content
</div>
);
}
```
### ClipWrapper
Automatically apply transitions to clip content:
```tsx
import { ClipWrapper } from '@json-render/remotion';
function MyClip({ clip }) {
return (
<ClipWrapper clip={clip}>
<div>My content with automatic transitions</div>
</ClipWrapper>
);
}
```

# Catalog
The catalog defines what AI can generate. It's your guardrail.
## What is a Catalog?
A catalog is a schema that defines:
- **Components** — UI elements AI can create (with props and optional slots)
- **Actions** — Operations AI can trigger
- **Functions** — Custom validation or transformation functions
## Creating a Catalog
```typescript
import { defineCatalog } from '@json-render/core';
import { schema } from '@json-render/react';
import { z } from 'zod';
const catalog = defineCatalog(schema, {
components: {
// Define each component with its props schema
Card: {
props: z.object({
title: z.string(),
description: z.string().nullable(),
padding: z.enum(['sm', 'md', 'lg']).nullable(),
}),
slots: ["default"], // Can contain other components
description: "Container card for grouping content",
},
Metric: {
props: z.object({
label: z.string(),
valuePath: z.string(), // JSON Pointer to data
format: z.enum(['currency', 'percent', 'number']),
}),
description: "Display a single metric value",
},
},
actions: {
submit_form: {
params: z.object({
formId: z.string(),
}),
description: 'Submit a form',
},
export_data: {
params: z.object({
format: z.enum(['csv', 'pdf', 'json']),
}),
description: 'Export data in various formats',
},
},
});
```
## Component Definition
Each component in the catalog has:
```typescript
{
props: z.object({...}), // Zod schema for props (use .nullable() for optional)
slots?: string[], // Named slots for children (e.g., ["default"])
description?: string, // Help AI understand when to use it
}
```
Use `slots: ["default"]` for components that can contain children. The slot name corresponds to where child elements are rendered.
## Generating AI Prompts
Use the `catalog.prompt()` method to generate a system prompt for AI:
```typescript
// Generate a system prompt from your catalog
const systemPrompt = catalog.prompt();
// Or with custom rules for the AI
const customPrompt = catalog.prompt({
customRules: [
"Always use Card as the root element for forms",
"Group related inputs in a Stack with direction=vertical",
],
});
// Pass this to your AI model as the system prompt
```

# Changelog
Notable changes and updates to json-render.
## v0.4.0
February 2026
### New: Custom Schema System
Create custom output formats with `defineSchema`. Each renderer now defines its own schema, enabling completely different spec formats for different use cases.
```typescript
import { defineSchema } from "@json-render/core";
const mySchema = defineSchema((s) => ({
spec: s.object({
pages: s.array(s.object({
title: s.string(),
blocks: s.array(s.ref("catalog.blocks")),
})),
}),
catalog: s.object({
blocks: s.map({ props: s.zod(), description: s.string() }),
}),
}), {
promptTemplate: myPromptTemplate,
});
```
### New: Component Slots
Components can now define which slots they accept. Use `["default"]` for regular children, or named slots like `["header", "footer"]` for more complex layouts.
```typescript
const catalog = defineCatalog(schema, {
components: {
Card: {
props: z.object({ title: z.string() }),
slots: ["default"], // accepts children
description: "A card container",
},
Layout: {
props: z.object({}),
slots: ["header", "content", "footer"], // named slots
description: "Page layout with header, content, footer",
},
},
});
```
### New: AI Prompt Generation
Catalogs now generate AI system prompts automatically with `catalog.prompt()`. The prompt includes all component definitions, props schemas, and action descriptions - ensuring the AI only generates valid specs.
```typescript
import { defineCatalog } from "@json-render/core";
import { schema } from "@json-render/react/schema";
const catalog = defineCatalog(schema, {
components: { /* ... */ },
actions: { /* ... */ },
});
// Generate system prompt for AI
const systemPrompt = catalog.prompt();
// Use with any AI SDK
const result = await streamText({
model: "claude-haiku-4.5",
system: systemPrompt,
prompt: userMessage,
});
```
### New: @json-render/remotion
Generate AI-powered videos with Remotion. Define video catalogs, stream timeline specs, and render with the Remotion Player.
```tsx
import { Player } from "@remotion/player";
import { Renderer, schema, standardComponentDefinitions } from "@json-render/remotion";
const catalog = defineCatalog(schema, {
components: standardComponentDefinitions,
transitions: standardTransitionDefinitions,
});
<Player
component={Renderer}
inputProps={{ spec }}
durationInFrames={spec.composition.durationInFrames}
fps={spec.composition.fps}
compositionWidth={spec.composition.width}
compositionHeight={spec.composition.height}
/>
```
Includes 10 standard video components (TitleCard, TypingText, SplitScreen, etc.), 7 transition types, and the ClipWrapper utility for custom components.
### New: SpecStream
SpecStream is json-render's streaming format for progressively building specs from JSONL patches. The new compiler API makes it easy to process streaming AI responses.
```typescript
import { createSpecStreamCompiler } from "@json-render/core";
const compiler = createSpecStreamCompiler<MySpec>();
// Process streaming chunks
const { result, newPatches } = compiler.push(chunk);
setSpec(result); // Update UI with partial result
```
### Improved: Dashboard Example
The dashboard example is now a full-featured accounting dashboard with:
- Persistent SQLite database with Drizzle ORM
- RESTful API for customers, invoices, expenses, accounts
- Draggable widget reordering
- AI-powered widget generation with streaming
- Real data binding to database records
### Improved: Documentation
- Interactive playground for testing specs
- New guides: Custom Schema, Streaming, Code Export
- Full API reference for all packages
- Integration guides: A2UI, AG-UI, Adaptive Cards, OpenAPI
### Breaking Changes
- `UITree` type renamed to `Spec`
- Schema is now imported from renderer packages (`@json-render/react`) not core
- `defineCatalog` now requires a schema as first argument
---
## v0.3.0
January 2026
Internal release with codegen foundations.
- Added `@json-render/codegen` package (spec traversal and JSX serialization)
- Configurable AI model via environment variables
- Documentation improvements and bug fixes
*Note: Only @json-render/core was published to npm for this release.*
---
## v0.2.0
January 2026
Initial public release.
- Core catalog and spec types
- React renderer with contexts for data, actions, visibility
- AI prompt generation from catalogs
- Basic streaming support
- Dashboard example application

# Code Export
Export generated UI as standalone code for your framework.
## Overview
While json-render is designed for dynamic rendering, you can export generated UI as static code. The code generation is intentionally project-specific so you have full control over:
- Component templates (standalone, no json-render dependencies)
- Package.json and project structure
- Framework-specific patterns (Next.js, Remix, etc.)
- How data is passed to components
## Architecture
Code export is split into two parts:
### 1. @json-render/codegen (utilities)
Framework-agnostic utilities for building code generators:
```typescript
import {
traverseSpec, // Walk the UI spec
collectUsedComponents, // Get all component types used
collectStatePaths, // Get all data binding paths
collectActions, // Get all action names
serializeProps, // Convert props to JSX string
} from '@json-render/codegen';
```
### 2. Your Project (generator)
Custom code generator specific to your project and framework:
```typescript
// lib/codegen/generator.ts
import { collectUsedComponents, serializeProps } from '@json-render/codegen';
export function generateNextJSProject(spec: Spec): GeneratedFile[] {
const components = collectUsedComponents(spec);
return [
{ path: 'package.json', content: '...' },
{ path: 'app/page.tsx', content: '...' },
// ... component files
];
}
```
## Example: Next.js Export
See the dashboard example for a complete implementation that exports:
- `package.json` - Dependencies and scripts
- `tsconfig.json` - TypeScript config
- `next.config.js` - Next.js config
- `app/layout.tsx` - Root layout
- `app/globals.css` - Global styles
- `app/page.tsx` - Generated page with data
- `components/ui/*.tsx` - Standalone components
## Standalone Components
The exported components are standalone with no json-render dependencies. They receive data as props instead of using hooks:
```tsx
// Generated component (standalone)
interface MetricProps {
label: string;
valuePath: string;
data?: Record<string, unknown>;
}
export function Metric({ label, valuePath, data }: MetricProps) {
const value = data ? getByPath(data, valuePath) : undefined;
return (
<div>
<span>{label}</span>
<span>{formatValue(value)}</span>
</div>
);
}
```
## Using the Utilities
### traverseSpec
```typescript
import { traverseSpec } from '@json-render/codegen';
traverseSpec(spec, (element, depth, parent) => {
console.log(' '.repeat(depth * 2) + element.type);
});
```
### collectUsedComponents
```typescript
import { collectUsedComponents } from '@json-render/codegen';
const components = collectUsedComponents(spec);
// Set { 'Card', 'Metric', 'Chart', 'Table' }
// Generate only the needed component files
for (const component of components) {
files.push({
path: `components/ui/${component.toLowerCase()}.tsx`,
content: componentTemplates[component],
});
}
```
### serializeProps
```typescript
import { serializeProps } from '@json-render/codegen';
const propsStr = serializeProps({
title: 'Dashboard',
columns: 3,
disabled: true,
});
// 'title="Dashboard" columns={3} disabled'
```
## Try It
Run the dashboard example and click "Export Project" to see code generation in action:
```bash
cd examples/dashboard
pnpm dev
# Open http://localhost:3001
# Generate a widget, then click "Export Project"
```

# Data Binding
Connect UI components to your application data using JSON Pointer paths.
## JSON Pointer Paths
json-render uses JSON Pointer (RFC 6901) for data paths:
```json
// Given this data:
{
"user": {
"name": "Alice",
"email": "alice@example.com"
},
"metrics": {
"revenue": 125000,
"growth": 0.15
}
}
// These paths access:
"/user/name" -> "Alice"
"/metrics/revenue" -> 125000
"/metrics/growth" -> 0.15
```
## StateProvider
Wrap your app with StateProvider to enable data binding:
```tsx
import { StateProvider } from '@json-render/react';
function App() {
const initialState = {
user: { name: 'Alice' },
form: { email: '', message: '' },
};
return (
<StateProvider initialState={initialState}>
{/* Your UI */}
</StateProvider>
);
}
```
## Reading Data
Use `useStateValue` for read-only access:
```tsx
import { useStateValue } from '@json-render/react';
function UserGreeting() {
const name = useStateValue('/user/name');
return <h1>Hello, {name}!</h1>;
}
```
## Two-Way Binding
Use `useStateBinding` for read-write access:
```tsx
import { useStateBinding } from '@json-render/react';
function EmailInput() {
const [email, setEmail] = useStateBinding('/form/email');
return (
<input
type="email"
value={email || ''}
onChange={(e) => setEmail(e.target.value)}
/>
);
}
```
## Using the State Context
Access the full state context for advanced use cases:
```tsx
import { useStateStore } from '@json-render/react';
function StateDebugger() {
const { data, setState, getValue, setValue } = useStateStore();
// Read any path
const revenue = getValue('/metrics/revenue');
// Write any path
const updateRevenue = () => setValue('/metrics/revenue', 150000);
// Replace all state
const resetState = () => setState({ user: {}, form: {} });
return <pre>{JSON.stringify(data, null, 2)}</pre>;
}
```
## In JSON UI Trees
AI can reference data paths in component props:
```json
{
"type": "Metric",
"props": {
"label": "Total Revenue",
"valuePath": "/metrics/revenue",
"format": "currency"
}
}
```

# OpenAPI Integration
Use json-render to generate dynamic forms and UIs from [OpenAPI/Swagger](https://swagger.io/specification/) schemas.
<div className="rounded-lg border border-amber-500/50 bg-amber-500/10 p-4 mb-8">
<p className="text-sm text-amber-700 dark:text-amber-300">
<strong>Concept:</strong> This page demonstrates how json-render can support OpenAPI schemas. The examples are illustrative and may require adaptation for production use.
</p>
</div>
## Why OpenAPI?
OpenAPI specifications describe your API's endpoints, request bodies, and response schemas. By converting OpenAPI schemas to json-render specs, you can:
- Automatically generate forms for API endpoints
- Display API responses with type-aware rendering
- Keep your UI in sync with your API schema
- Let AI generate UIs that match your API contracts
## Example OpenAPI Schema
A typical OpenAPI schema for a request body:
```json
{
"openapi": "3.0.0",
"paths": {
"/users": {
"post": {
"summary": "Create a new user",
"operationId": "createUser",
"requestBody": {
"required": true,
"content": {
"application/json": {
"schema": {
"$ref": "#/components/schemas/CreateUserRequest"
}
}
}
}
}
}
},
"components": {
"schemas": {
"CreateUserRequest": {
"type": "object",
"required": ["email", "name"],
"properties": {
"name": {
"type": "string",
"description": "User's full name",
"minLength": 1,
"maxLength": 100
},
"email": {
"type": "string",
"format": "email",
"description": "User's email address"
},
"age": {
"type": "integer",
"minimum": 0,
"maximum": 150,
"description": "User's age"
},
"role": {
"type": "string",
"enum": ["admin", "user", "guest"],
"default": "user",
"description": "User's role"
},
"preferences": {
"type": "object",
"properties": {
"newsletter": {
"type": "boolean",
"default": false
},
"theme": {
"type": "string",
"enum": ["light", "dark", "system"]
}
}
}
}
}
}
}
}
```
## Define an OpenAPI-to-UI Catalog
Create components that map to OpenAPI data types:
```typescript
import { createCatalog } from '@json-render/core';
import { z } from 'zod';
export const openapiCatalog = createCatalog({
components: {
Form: {
description: 'API form container',
props: z.object({
operationId: z.string(),
endpoint: z.string(),
method: z.enum(['GET', 'POST', 'PUT', 'PATCH', 'DELETE']),
title: z.string().optional(),
description: z.string().optional(),
}),
},
StringField: {
description: 'String input field',
props: z.object({
name: z.string(),
label: z.string(),
description: z.string().optional(),
required: z.boolean().optional(),
format: z.enum(['text', 'email', 'uri', 'uuid', 'date', 'date-time', 'password']).optional(),
minLength: z.number().optional(),
maxLength: z.number().optional(),
pattern: z.string().optional(),
placeholder: z.string().optional(),
defaultValue: z.string().optional(),
}),
},
NumberField: {
description: 'Number input field',
props: z.object({
name: z.string(),
label: z.string(),
description: z.string().optional(),
required: z.boolean().optional(),
type: z.enum(['integer', 'number']).optional(),
minimum: z.number().optional(),
maximum: z.number().optional(),
defaultValue: z.number().optional(),
}),
},
BooleanField: {
description: 'Boolean toggle field',
props: z.object({
name: z.string(),
label: z.string(),
description: z.string().optional(),
defaultValue: z.boolean().optional(),
}),
},
EnumField: {
description: 'Enum selection field',
props: z.object({
name: z.string(),
label: z.string(),
description: z.string().optional(),
required: z.boolean().optional(),
options: z.array(z.object({
value: z.string(),
label: z.string().optional(),
})),
defaultValue: z.string().optional(),
}),
},
ObjectField: {
description: 'Nested object group',
props: z.object({
name: z.string(),
label: z.string(),
description: z.string().optional(),
collapsible: z.boolean().optional(),
}),
},
},
actions: {
submit: {
description: 'Submit form to API endpoint',
params: z.object({ operationId: z.string() }),
},
reset: {
description: 'Reset form to defaults',
params: z.object({}),
},
},
});
```
## Convert OpenAPI Schema to Spec
Transform OpenAPI schemas into json-render specs by recursively walking the schema properties and mapping each type to the corresponding catalog component. The converter handles nested objects, enums, arrays, and all primitive types.
## Usage Example
```tsx
'use client';
import { OpenAPIForm } from './openapi-form';
import { operationToSpec } from './openapi-to-spec';
// Your OpenAPI schema (typically loaded from your API)
const createUserSchema = {
type: 'object',
required: ['email', 'name'],
properties: {
name: { type: 'string', description: "User's full name" },
email: { type: 'string', format: 'email', description: "User's email" },
age: { type: 'integer', minimum: 0, maximum: 150 },
role: { type: 'string', enum: ['admin', 'user', 'guest'], default: 'user' },
},
};
// Convert to spec
const spec = operationToSpec(
'createUser',
'POST',
'/api/users',
createUserSchema,
'Create User',
'Add a new user to the system',
);
export function CreateUserForm() {
const handleSubmit = async (data: Record<string, unknown>) => {
const response = await fetch('/api/users', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(data),
});
if (response.ok) {
console.log('User created!');
}
};
return <OpenAPIForm spec={spec} onSubmit={handleSubmit} />;
}
```
## Auto-generating from OpenAPI Document
Load and parse an OpenAPI document to generate forms for all operations:
```typescript
import SwaggerParser from '@apidevtools/swagger-parser';
import { operationToSpec } from './openapi-to-spec';
export async function loadOpenAPISpecs(specUrl: string) {
const api = await SwaggerParser.dereference(specUrl);
const specs: Record<string, any> = {};
for (const [path, methods] of Object.entries(api.paths)) {
for (const [method, operation] of Object.entries(methods)) {
if (!operation.requestBody?.content?.['application/json']?.schema) continue;
const schema = operation.requestBody.content['application/json'].schema;
const operationId = operation.operationId || `${method}_${path.replace(/\//g, '_')}`;
specs[operationId] = operationToSpec(
operationId,
method,
path,
schema,
operation.summary,
operation.description,
);
}
}
return specs;
}
// Usage
const specs = await loadOpenAPISpecs('https://api.example.com/openapi.json');
// specs.createUser, specs.updateUser, etc.
```

# Introduction
Predictable. Guardrailed. Fast. Let users generate dashboards, widgets, apps, and data visualizations from prompts.
## What is json-render?
json-render lets end users generate UI from natural language prompts — safely constrained to components you define. You set the guardrails: what components exist, what props they take, what actions are available. AI generates JSON that matches your schema, and your components render it natively.
## Why json-render?
### Guardrailed
AI can only use components in your catalog. No arbitrary code generation.
### Predictable
JSON output matches your schema, every time. Actions are declared by name, you control what they do.
### Fast
Stream and render progressively as the model responds. No waiting for completion.
## How it works
1. Define the guardrails — what components, actions, and data bindings AI can use
2. Users prompt — end users describe what they want in natural language
3. AI generates JSON — output is always predictable, constrained to your catalog
4. Render fast — stream and render progressively as the model responds

# Quick Start
Get up and running with json-render in 5 minutes.
## 1. Define your catalog
Create a catalog that defines what components AI can use:
```typescript
// lib/catalog.ts
import { defineCatalog } from '@json-render/core';
import { schema } from '@json-render/react';
import { z } from 'zod';
export const catalog = defineCatalog(schema, {
components: {
Card: {
props: z.object({
title: z.string(),
description: z.string().nullable(),
}),
slots: ["default"],
description: "Container card with optional title",
},
Button: {
props: z.object({
label: z.string(),
action: z.string().nullable(),
}),
description: "Clickable button that triggers an action",
},
Text: {
props: z.object({
content: z.string(),
}),
description: "Text paragraph",
},
},
actions: {
submit: {
params: z.object({ formId: z.string() }),
description: "Submit a form",
},
navigate: {
params: z.object({ url: z.string() }),
description: "Navigate to a URL",
},
},
});
```
## 2. Define your components
Use `defineRegistry` to map catalog types to React components. Each component receives type-safe `props`, `children`, and `onAction`:
```tsx
// lib/registry.tsx
import { defineRegistry } from '@json-render/react';
import { catalog } from './catalog';
export const { registry } = defineRegistry(catalog, {
components: {
Card: ({ props, children }) => (
<div className="p-4 border rounded-lg">
<h2 className="font-bold">{props.title}</h2>
{props.description && (
<p className="text-gray-600">{props.description}</p>
)}
{children}
</div>
),
Button: ({ props, onAction }) => (
<button
className="px-4 py-2 bg-blue-500 text-white rounded"
onClick={() => onAction?.({ name: props.action })}
>
{props.label}
</button>
),
Text: ({ props }) => (
<p>{props.content}</p>
),
},
});
```
## 3. Create an API route
Set up a streaming API route for AI generation:
```typescript
// app/api/generate/route.ts
import { streamText } from 'ai';
import { catalog } from '@/lib/catalog';
export async function POST(req: Request) {
const { prompt } = await req.json();
// Generate system prompt from catalog
const systemPrompt = catalog.prompt();
const result = streamText({
model: 'anthropic/claude-haiku-4.5',
system: systemPrompt,
prompt,
});
return result.toTextStreamResponse();
}
```
## 4. Render the UI
Use providers and the `Renderer` with your registry to display AI-generated UI:
```tsx
// app/page.tsx
'use client';
import { Renderer, StateProvider, ActionProvider, VisibilityProvider, useUIStream } from '@json-render/react';
import { registry } from '@/lib/registry';
export default function Page() {
const { spec, isStreaming, send } = useUIStream({
api: '/api/generate',
});
const handleSubmit = (e: React.FormEvent<HTMLFormElement>) => {
e.preventDefault();
const formData = new FormData(e.currentTarget);
send(formData.get('prompt') as string);
};
return (
<StateProvider initialState={{}}>
<VisibilityProvider>
<ActionProvider handlers={{
submit: (params) => console.log('Submit:', params),
navigate: (params) => console.log('Navigate:', params),
}}>
<form onSubmit={handleSubmit}>
<input
name="prompt"
placeholder="Describe what you want..."
className="border p-2 rounded"
/>
<button type="submit" disabled={isStreaming}>
Generate
</button>
</form>
<div className="mt-8">
<Renderer spec={spec} registry={registry} loading={isStreaming} />
</div>
</ActionProvider>
</VisibilityProvider>
</StateProvider>
);
}
```

# Registry
Register React components and action handlers to bring your catalog to life.
## defineRegistry
Use `defineRegistry` to create a type-safe registry from your catalog. Pass your components, actions, or both in a single call:
```tsx
import { defineRegistry } from '@json-render/react';
import { myCatalog } from './catalog';
export const { registry, handlers, executeAction } = defineRegistry(myCatalog, {
components: {
Card: ({ props, children }) => (
<div className="card">
<h2>{props.title}</h2>
{props.description && <p>{props.description}</p>}
{children}
</div>
),
Button: ({ props, onAction }) => (
<button onClick={() => onAction?.({ name: props.action })}>
{props.label}
</button>
),
},
actions: {
submit_form: async (params, setState) => {
const res = await fetch('/api/submit', {
method: 'POST',
body: JSON.stringify(params),
});
const result = await res.json();
setState((prev) => ({ ...prev, formResult: result }));
},
export_data: async (params) => {
const blob = await generateExport(params.format);
downloadBlob(blob, `export.${params.format}`);
},
},
});
```
The returned object contains:
- `registry` - component registry for `<Renderer />`
- `handlers` - factory for ActionProvider-compatible handlers
- `executeAction` - imperative action dispatch (for use outside the React tree)
## Component Props
Each component in the registry receives a `ComponentContext` object:
```typescript
interface ComponentContext {
props: T; // Type-safe props from your catalog
children?: React.ReactNode; // Rendered children (for slot components)
onAction?: (action: ActionTrigger) => void; // Dispatch an action
loading?: boolean; // Whether the renderer is in a loading state
}
```
Props are automatically inferred from your catalog, so `props.title` is typed as `string` if your catalog defines it that way.
## Action Handlers
Instead of AI generating arbitrary code, it declares *intent* by name. Your application provides the implementation. This is a core guardrail.
### Defining Actions
Define available actions in your catalog:
```typescript
import { defineCatalog } from '@json-render/core';
import { schema } from '@json-render/react';
import { z } from 'zod';
const catalog = defineCatalog(schema, {
components: { /* ... */ },
actions: {
submit_form: {
params: z.object({
formId: z.string(),
}),
description: 'Submit a form',
},
export_data: {
params: z.object({
format: z.enum(['csv', 'pdf', 'json']),
}),
},
navigate: {
params: z.object({
url: z.string(),
}),
},
},
});
```
### Implementing Action Handlers
Action handlers receive `(params, setState, data)` and are defined inside `defineRegistry`:
```tsx
export const { handlers, executeAction } = defineRegistry(catalog, {
actions: {
submit_form: async (params, setState) => {
const response = await fetch('/api/submit', {
method: 'POST',
body: JSON.stringify({ formId: params.formId }),
});
const result = await response.json();
setState((prev) => ({ ...prev, formResult: result }));
},
export_data: async (params) => {
const blob = await generateExport(params.format);
downloadBlob(blob, `export.${params.format}`);
},
navigate: (params) => {
window.location.href = params.url;
},
},
});
```
## Using Data Binding
Use hooks inside your registry components to read and write data:
```tsx
import { useStateStore } from '@json-render/react';
import { getByPath } from '@json-render/core';
// Inside defineRegistry components:
Metric: ({ props }) => {
const { data } = useStateStore();
const value = getByPath(data, props.valuePath);
return (
<div className="metric">
<span className="label">{props.label}</span>
<span className="value">{formatValue(value)}</span>
</div>
);
},
TextField: ({ props }) => {
const { data, set } = useStateStore();
const value = getByPath(data, props.valuePath) as string;
return (
<input
value={value || ''}
onChange={(e) => set(props.valuePath, e.target.value)}
placeholder={props.placeholder}
/>
);
},
```
## Using the Renderer
Wire everything together with providers and the `<Renderer />` component:
```tsx
import { useMemo, useRef } from 'react';
import {
Renderer,
StateProvider,
VisibilityProvider,
ActionProvider,
} from '@json-render/react';
import { registry, handlers } from './registry';
function App({ spec, data, setState }) {
const dataRef = useRef(data);
const setStateRef = useRef(setState);
dataRef.current = data;
setStateRef.current = setState;
const actionHandlers = useMemo(
() => handlers(() => setStateRef.current, () => dataRef.current),
[],
);
return (
<StateProvider initialState={data}>
<VisibilityProvider>
<ActionProvider handlers={actionHandlers}>
<Renderer spec={spec} registry={registry} />
</ActionProvider>
</VisibilityProvider>
</StateProvider>
);
}
```

# Schemas
Schemas define the structure and validation rules for your UI specs.
## What is a Schema?
A schema defines the JSON structure that describes your UI. It includes:
- **Element structure** — How components are nested and referenced
- **Property types** — What props each component accepts
- **Data binding syntax** — How to reference dynamic data
- **Action format** — How user interactions are defined
## Schema-Agnostic by Design
json-render can work with any JSON schema. `@json-render/core` provides the primitives to define catalogs and renderers for any format:
- **@json-render/react** — The built-in flat element tree schema
- **[A2UI](/docs/a2ui)** — Google's Agent-to-User Interaction protocol
- **[Adaptive Cards](/docs/adaptive-cards)** — Microsoft's platform-agnostic UI format
- **AG-UI** — CopilotKit's Agent User Interaction Protocol
- **OpenAPI/Swagger** — API documentation schemas for dynamic forms
- **Custom schemas** — Design your own format tailored to your domain
See the [Custom Schema guide](/docs/custom-schema) to learn how to implement support for any schema.
## Built-in Schema
`@json-render/react` uses a flat element tree schema with a root key and elements map:
```json
{
"root": "card-1",
"elements": {
"card-1": {
"type": "Card",
"props": { "title": "Dashboard" },
"children": ["text-1", "button-1"]
},
"text-1": {
"type": "Text",
"props": { "content": "Welcome, $data.user.name" },
"children": []
},
"button-1": {
"type": "Button",
"props": { "label": "Click me" },
"children": []
}
}
}
```
## Schema Components
### Element Structure
In the built-in schema, each element in the elements map has this structure:
```typescript
interface Element {
type: string; // Component type from catalog
props: Record<string, any>; // Component properties
children: string[]; // Array of child element keys
visible?: VisibilityRule; // Conditional display
}
```
### Data Binding Syntax
Reference dynamic data using the `$data` prefix in props:
```json
{
"type": "Text",
"props": {
"content": "$data.user.name",
"count": "$data.items.length"
},
"children": []
}
```
### Action Format
Actions are defined in the catalog and referenced from components. The renderer handles action execution:
```typescript
// In your catalog
actions: {
navigate: {
params: z.object({ url: z.string() }),
description: 'Navigate to a URL',
},
apiCall: {
params: z.object({
endpoint: z.string(),
method: z.enum(['GET', 'POST', 'PUT', 'DELETE']),
}),
description: 'Make an API request',
},
}
```
## Custom Schemas
`@json-render/core` is schema-agnostic. You can define any JSON structure:
```typescript
import { z } from 'zod';
// Define your own element schema
const MyElementSchema = z.object({
component: z.string(),
settings: z.record(z.unknown()),
nested: z.array(z.lazy(() => MyElementSchema)).optional(),
});
// Define your own data binding format
const BoundValue = z.object({
literal: z.string().optional(),
path: z.string().optional(), // e.g., "/users/0/name"
});
// Define your own action format
const ActionSchema = z.object({
name: z.string(),
context: z.record(z.unknown()).optional(),
});
```
## Schema vs Catalog
The schema and catalog work together but serve different purposes:
- **Schema** — Defines the JSON structure (how elements are organized)
- **Catalog** — Defines available components and their props (what can be used)
The schema is the grammar; the catalog is the vocabulary.

# Specs
A spec is a JSON document that describes your UI.
## What is a Spec?
A spec (specification) is the actual JSON that describes a UI. It conforms to a [schema](/docs/schemas) and uses components from a [catalog](/docs/catalog). Specs can be:
- Generated by AI in real-time
- Stored in a database
- Streamed progressively from a server
- Hand-authored as JSON files
json-render is schema-agnostic — your specs can follow any JSON structure you choose.
## Example Specs
### Simple Spec
A basic spec using the `@json-render/react` schema. Note the flat structure with a `root` key and `elements` map:
```json
{
"root": "card-1",
"elements": {
"card-1": {
"type": "Card",
"props": { "title": "Welcome" },
"children": ["text-1"]
},
"text-1": {
"type": "Text",
"props": { "content": "Hello, $data.user.name!" },
"children": []
}
}
}
```
### Complex Spec
A more complex spec with multiple nested elements:
```json
{
"root": "card-1",
"elements": {
"card-1": {
"type": "Card",
"props": { "title": "User Profile", "padding": "md" },
"children": ["row-1", "button-1"]
},
"row-1": {
"type": "Row",
"props": { "gap": "md" },
"children": ["avatar-1", "stack-1"]
},
"avatar-1": {
"type": "Avatar",
"props": { "src": "$data.user.avatar", "alt": "$data.user.name" },
"children": []
},
"stack-1": {
"type": "Stack",
"props": { "gap": "sm" },
"children": ["name-text", "email-text"]
},
"name-text": {
"type": "Text",
"props": { "content": "$data.user.name", "variant": "heading" },
"children": []
},
"email-text": {
"type": "Text",
"props": { "content": "$data.user.email", "variant": "caption" },
"children": []
},
"button-1": {
"type": "Button",
"props": { "label": "Edit Profile" },
"children": []
}
}
}
```
### Block-Level Spec
A high-level spec using semantic blocks for page layouts:
```json
{
"root": "page",
"elements": {
"page": {
"type": "Page",
"props": {},
"children": ["header", "hero", "features", "footer"]
},
"header": {
"type": "Header",
"props": { "logo": "/logo.svg", "navItems": ["Products", "Pricing", "Docs"] },
"children": []
},
"hero": {
"type": "Hero",
"props": {
"title": "Build UIs with JSON",
"subtitle": "Let AI generate your interfaces",
"ctaLabel": "Get Started",
"ctaHref": "/docs"
},
"children": []
},
"features": {
"type": "Features",
"props": { "columns": 3 },
"children": ["feature-1", "feature-2", "feature-3"]
},
"feature-1": {
"type": "Feature",
"props": { "icon": "zap", "title": "Fast", "description": "Render UIs in milliseconds" },
"children": []
},
"feature-2": {
"type": "Feature",
"props": { "icon": "shield", "title": "Secure", "description": "Validate all specs against your catalog" },
"children": []
},
"feature-3": {
"type": "Feature",
"props": { "icon": "sparkles", "title": "AI-Ready", "description": "Generate prompts from your catalog" },
"children": []
},
"footer": {
"type": "Footer",
"props": { "copyright": "2025 Acme Inc", "links": ["Privacy", "Terms", "Contact"] },
"children": []
}
}
}
```
## Spec Anatomy
### Root and Elements
Every spec has a `root` key pointing to the entry element, and an `elements` map containing all elements:
```json
{
"root": "card-1",
"elements": {
"card-1": {
"type": "Card",
"props": { "title": "My Card" },
"children": ["text-1"]
},
"text-1": { ... }
}
}
```
### Element Structure
Each element in the map has a consistent shape:
```json
{
"type": "ComponentName",
"props": { "label": "Hello" },
"children": ["child-1", "child-2"]
}
```
- `type` — Component type from your catalog
- `props` — Component properties
- `children` — Array of child element keys
### Dynamic Data
Props can reference data using `$data` paths:
```json
{
"type": "Metric",
"props": {
"label": "Total Revenue",
"value": "$data.metrics.revenue",
"change": "$data.metrics.revenueChange"
},
"children": []
}
```
### Conditional Visibility
Control when elements appear using the `visible` property:
```json
{
"type": "Alert",
"props": {
"message": "You have unsaved changes"
},
"children": [],
"visible": {
"path": "$data.form.isDirty",
"operator": "eq",
"value": true
}
}
```
## Working with Specs
### Rendering a Spec
```tsx
import { Renderer } from '@json-render/react';
function MyApp({ spec, data }) {
return (
<Renderer
spec={spec}
data={data}
registry={registry}
/>
);
}
```
### Validating a Spec
```typescript
import { validate } from '@json-render/core';
const result = validate(spec, catalog);
if (!result.valid) {
console.error('Invalid spec:', result.errors);
}
```
### Streaming Specs
Specs can be streamed incrementally for progressive rendering:
```tsx
import { useUIStream } from '@json-render/react';
function GenerativeUI() {
const { spec, isStreaming } = useUIStream({
api: '/api/generate',
});
return (
<Renderer

## Spec Sources
Specs can come from various sources:
- **AI Generation** — LLMs generate specs based on prompts and catalog
- **Database** — Store specs as JSON and load dynamically
- **API Response** — Server returns specs based on user/context
- **Static Files** — Pre-built specs for known UI patterns

# Streaming
Progressively render UI as AI generates it.
## SpecStream Format
json-render uses **SpecStream**, a JSONL-based streaming format where each line is a JSON patch operation that progressively builds your spec:
```json
{"op":"add","path":"/root","value":"root"}
{"op":"add","path":"/elements/root","value":{"type":"Card","props":{"title":"Dashboard"},"children":["metric-1","metric-2"]}}
{"op":"add","path":"/elements/metric-1","value":{"type":"Metric","props":{"label":"Revenue"}}}
{"op":"add","path":"/elements/metric-2","value":{"type":"Metric","props":{"label":"Users"}}}
```
## useUIStream Hook
The hook handles parsing and state management:
```tsx
import { useUIStream } from '@json-render/react';
function App() {
const {
spec, // Current UI spec state
isStreaming, // True while streaming
error, // Any error that occurred
send, // Function to start generation
clear, // Function to reset spec and error
} = useUIStream({
api: '/api/generate',
onComplete: (spec) => {}, // Optional: called when streaming completes
onError: (error) => {}, // Optional: called when an error occurs
});
}
```
## Patch Operations (RFC 6902)
SpecStream uses [RFC 6902 JSON Patch](https://datatracker.ietf.org/doc/html/rfc6902) operations:
- `add` — Add a value at a path (creates or replaces for objects, inserts for arrays)
- `remove` — Remove the value at a path
- `replace` — Replace an existing value at a path
- `move` — Move a value from one path to another (requires `from`)
- `copy` — Copy a value from one path to another (requires `from`)
- `test` — Assert that a value at a path equals the given value
## Path Format
Paths use a key-based format for elements:
```bash
/root -> Root element
/root/children -> Children of root
/elements/card-1 -> Element with key "card-1"
/elements/card-1/children -> Children of card-1
```
## Server-Side Setup
Ensure your API route streams properly:
```typescript
import { streamText } from 'ai';
import { catalog } from '@/lib/catalog';
export async function POST(req: Request) {
const { prompt } = await req.json();
const result = streamText({
model: 'anthropic/claude-haiku-4.5',
system: catalog.prompt(),
prompt,
});
// Return as a streaming response
return result.toTextStreamResponse();
}
```
## Progressive Rendering
The Renderer automatically updates as the spec changes:
```tsx
function App() {
const { spec, isStreaming } = useUIStream({ api: '/api/generate' });
return (
<div>
{isStreaming && <LoadingIndicator />}
<Renderer spec={spec} registry={registry} loading={isStreaming} />
</div>
);
}
```
## Aborting Streams
Calling `send` again automatically aborts the previous request. Use `clear` to reset the spec and error state:
```tsx
function App() {
const { isStreaming, send, clear } = useUIStream({
api: '/api/generate',
});
return (
<div>
<button onClick={() => send('Create dashboard')}>
Generate
</button>
<button onClick={clear}>Reset</button>
</div>
);
}
```
## Low-Level SpecStream API
For custom streaming implementations, use the SpecStream compiler directly:
```typescript
import { createSpecStreamCompiler } from '@json-render/core';
// Create a compiler for your spec type
const compiler = createSpecStreamCompiler<MySpec>();
// Process streaming chunks from AI
async function processStream(reader: ReadableStreamDefaultReader) {
while (true) {
const { done, value } = await reader.read();
if (done) break;
const { result, newPatches } = compiler.push(value);
if (newPatches.length > 0) {
// Update UI with partial result
setSpec(result);
}
}
// Get final compiled result
return compiler.getResult();
}
```
### One-Shot Compilation
For non-streaming scenarios, compile entire SpecStream at once:
```typescript
import { compileSpecStream } from '@json-render/core';
const jsonl = `{"op":"add","path":"/root","value":{"type":"Card"}}
{"op":"add","path":"/root/props","value":{"title":"Hello"}}`;
const spec = compileSpecStream<MySpec>(jsonl);
// { root: { type: "Card", props: { title: "Hello" } } }
```

# Validation
Validate form inputs with built-in and custom functions.
## Built-in Validators
json-render includes common validation functions:
- `required` — Value must be non-empty
- `email` — Valid email format
- `minLength` — Minimum string length
- `maxLength` — Maximum string length
- `pattern` — Match a regex pattern
- `min` — Minimum numeric value
- `max` — Maximum numeric value
## Using Validation in JSON
```json
{
"type": "TextField",
"props": {
"label": "Email",
"valuePath": "/form/email",
"checks": [
{ "fn": "required", "message": "Email is required" },
{ "fn": "email", "message": "Invalid email format" }
],
"validateOn": "blur"
}
}
```
## Validation with Parameters
```json
{
"type": "TextField",
"props": {
"label": "Password",
"valuePath": "/form/password",
"checks": [
{ "fn": "required", "message": "Password is required" },
{
"fn": "minLength",
"args": { "length": 8 },
"message": "Password must be at least 8 characters"
},
{
"fn": "pattern",
"args": { "pattern": "[A-Z]" },
"message": "Must contain at least one uppercase letter"
}
]
}
}
```
## Custom Validation Functions
Define custom validators in your catalog:
```typescript
import { defineCatalog } from '@json-render/core';
import { schema } from '@json-render/react';
import { z } from 'zod';
const catalog = defineCatalog(schema, {
components: { /* ... */ },
functions: {
isValidPhone: {
description: 'Validates phone number format',
},
isUniqueEmail: {
description: 'Checks if email is not already registered',
},
},
});
```
Then implement them in your ValidationProvider:
```tsx
import { ValidationProvider } from '@json-render/react';
function App() {
const customValidators = {
isValidPhone: (value) => {
const phoneRegex = /^\+?[1-9]\d{1,14}$/;
return phoneRegex.test(value);
},
isUniqueEmail: async (value) => {
const response = await fetch(`/api/check-email?email=${value}`);
const { available } = await response.json();
return available;
},
};
return (
<ValidationProvider functions={customValidators}>
{/* Your UI */}
</ValidationProvider>
);
}
```
## Using in Components
```tsx
import { useFieldValidation } from '@json-render/react';
function TextField({ props }) {
const { value, setValue, errors, validate } = useFieldValidation(
props.valuePath,
props.checks
);
return (
<div>
<label>{props.label}</label>
<input
value={value || ''}
onChange={(e) => setValue(e.target.value)}
onBlur={() => validate()}
/>
{errors.map((error, i) => (
<p key={i} className="text-red-500 text-sm">{error}</p>
))}
</div>
);
}
```
## Validation Timing
Control when validation runs with `validateOn`:
- `change` — Validate on every input change
- `blur` — Validate when field loses focus
- `submit` — Validate only on form submission

# Visibility
Conditionally show or hide components based on data, auth, or logic.
## VisibilityProvider
Wrap your app with VisibilityProvider to enable conditional rendering:
```tsx
import { VisibilityProvider } from '@json-render/react';
function App() {
return (
<StateProvider initialState={data}>
<VisibilityProvider>
{/* Components can now use visibility conditions */}
</VisibilityProvider>
</StateProvider>
);
}
```
## Path-Based Visibility
Show/hide based on data values:
```json
{
"type": "Alert",
"props": { "message": "Form has errors" },
"visible": { "path": "/form/hasErrors" }
}
// Visible when /form/hasErrors is truthy
```
## Auth-Based Visibility
Show/hide based on authentication state:
```json
{
"type": "AdminPanel",
"visible": { "auth": "signedIn" }
}
// Options: "signedIn", "signedOut", "admin", etc.
```
## Logic Expressions
Combine conditions with logic operators:
```json
// AND - all conditions must be true
{
"type": "SubmitButton",
"visible": {
"and": [
{ "path": "/form/isValid" },
{ "path": "/form/hasChanges" }
]
}
}
// OR - any condition must be true
{
"type": "HelpText",
"visible": {
"or": [
{ "path": "/user/isNew" },
{ "path": "/settings/showHelp" }
]
}
}
// NOT - invert a condition
{
"type": "WelcomeBanner",
"visible": {
"not": { "path": "/user/hasSeenWelcome" }
}
}
```
## Comparison Operators
```json
// Equal
{
"visible": {
"eq": [{ "path": "/user/role" }, "admin"]
}
}
// Greater than
{
"visible": {
"gt": [{ "path": "/cart/total" }, 100]
}
}
// Available: eq, ne, gt, gte, lt, lte
```
## Complex Example
```json
{
"type": "RefundButton",
"props": { "label": "Process Refund" },
"visible": {
"and": [
{ "auth": "signedIn" },
{ "eq": [{ "path": "/user/role" }, "support"] },
{ "gt": [{ "path": "/order/amount" }, 0] },
{ "not": { "path": "/order/isRefunded" } }
]
}
}
```
## Using in Components
```tsx
import { useIsVisible } from '@json-render/react';
// The Renderer handles visibility automatically, but you can also use the hook
function ConditionalContent({ condition, children }) {
const isVisible = useIsVisible(condition);
if (!isVisible) return null;
return <div>{children}</div>;
}
```
