 Notable changes and updates to json-render.

+## v0.8.0
+
+February 2026
+
+### New: `@json-render/react-pdf`
+
+PDF renderer for json-render, powered by [`@react-pdf/renderer`](https://react-pdf.org/). Define catalogs and registries the same way as `@json-render/react`, but output PDF documents instead of web UI.
+
+```bash
+npm install @json-render/core @json-render/react-pdf
+```
+
+```typescript
+import { renderToBuffer } from "@json-render/react-pdf";
+import type { Spec } from "@json-render/core";
+
+const spec: Spec = {
+  root: "doc",
+  elements: {
+    doc: { type: "Document", props: { title: "Invoice" }, children: ["page"] },
+    page: {
+      type: "Page",
+      props: { size: "A4" },
+      children: ["heading", "table"],
+    },
+    heading: {
+      type: "Heading",
+      props: { text: "Invoice #1234", level: "h1" },
+      children: [],
+    },
+    table: {
+      type: "Table",
+      props: {
+        columns: [
+          { header: "Item", width: "60%" },
+          { header: "Price", width: "40%", align: "right" },
+        ],
+        rows: [
+          ["Widget A", "$10.00"],
+          ["Widget B", "$25.00"],
+        ],
+      },
+      children: [],
+    },
+  },
+};
+
+const buffer = await renderToBuffer(spec);
+```
+
+Server-side rendering APIs:
+
+- `renderToBuffer(spec)` -- render to an in-memory PDF buffer
+- `renderToStream(spec)` -- render to a readable stream (pipe to HTTP response)
+- `renderToFile(spec, path)` -- render directly to a file
+
+15 standard components covering document structure (Document, Page), layout (View, Row, Column), content (Heading, Text, Image, Link), data (Table, List), decorative (Divider, Spacer), and page-level (PageNumber).
+
+Supports custom catalogs with `defineRegistry`, server-safe imports via `@json-render/react-pdf/server`, and full context support (state, visibility, actions, validation, repeat scopes).

-# Stripe App Example
+# Stripe App Examples

-A [Stripe App](https://stripe.com/docs/stripe-apps) example demonstrating how to use json-render to build dynamic, AI-generated UI within the Stripe Dashboard.
+[Stripe Apps](https://stripe.com/docs/stripe-apps) examples demonstrating how to use json-render to build dynamic, AI-generated UI within the Stripe Dashboard.

-## Overview
+## Structure

-This example shows how to integrate json-render with Stripe's UI Extension SDK to create dashboard views that can be dynamically generated from prompts. The app includes:
+| Folder | Description |
+|--------|-------------|
+| [api/](./api) | Next.js server providing the `/api/generate` endpoint for AI-powered UI generation |
+| [drawer-app/](./drawer-app) | Standard Stripe App that renders in the Dashboard drawer (sidebar) |
+| [fullpage-app/](./fullpage-app) | Full-page Stripe App using `FullPageView` (requires alpha access) |

- **Home** - Revenue dashboard with AI-powered UI generation
- **Customers** - Customer list and management
- **Customer Details** - Individual customer view
- **Payments** - Payment list and details
- **Subscriptions** - Subscription management
- **Invoices** - Invoice list
- **Products** - Product catalog
+## Quick Start

-## Features
-
- Full Stripe UIXT component catalog mapped to json-render
- Dynamic spec generation from natural language prompts
- Real-time data binding with Stripe API
- Action handlers for Stripe operations (refunds, subscriptions, etc.)
-
-## Getting Started
-
-### Prerequisites
-
- [Stripe CLI](https://stripe.com/docs/stripe-cli) installed
- A Stripe account with app development enabled
-
-### Installation
+### 1. Start the API server

 ```bash
-# Install dependencies
+cd api
 pnpm install
+cp .env.example .env  # Set AI_GATEWAY_API_KEY
+pnpm dev
+```

-# Start the Stripe App in development mode
+### 2. Start a Stripe App
+
+For the standard drawer app:
+
+```bash
+cd drawer-app
+pnpm install
+pnpm setup
 stripe apps start
 ```

-### Development
-
-The app uses the Stripe UI Extension SDK which handles authentication automatically - no API keys required in your environment.
+For the full-page app (requires alpha access):

 ```bash
-# Run linting
-pnpm lint
-
-# Run tests
-pnpm test
+cd fullpage-app
+pnpm install
+cp .env.example .env  # Set STRIPE_APP_ID
+pnpm setup
+stripe apps start
+# Navigate to https://dashboard.stripe.com/test/app/<your-app-id>
 ```

-## How It Works
+## Notes

-1. **Component Catalog**: Maps json-render component types to Stripe UIXT components (`Box`, `Button`, `Badge`, etc.)
-
-2. **Action Handlers**: Defines actions that can be triggered from the UI (e.g., `refundPayment`, `cancelSubscription`)
-
-3. **StripeRenderer**: A custom renderer that uses the Stripe component catalog to render json-render specs
-
-4. **Views**: Each view fetches data from the Stripe API and renders it using json-render specs
-
-## Example Usage
-
-```tsx
-import { StripeRenderer, stripeCatalog } from "./lib/render";
-import type { Spec } from "@json-render/react";
-
-const spec: Spec = {
-  root: "container",
-  elements: {
-    container: {
-      type: "Stack",
-      props: { direction: "vertical", gap: "medium" },
-      children: ["heading", "metric"],
-    },
-    heading: {
-      type: "Heading",
-      props: { text: "Revenue", size: "large" },
-      children: [],
-    },
-    metric: {
-      type: "Metric",
-      props: { label: "Total", value: "$12,345", format: "currency" },
-      children: [],
-    },
-  },
-};
-
-function MyView() {
-  return <StripeRenderer spec={spec} catalog={stripeCatalog} />;
-}
-```

+- The AI generation feature requires the API server to be running. Without it, the apps fall back to locally generated specs using real Stripe data.
+- The `fullpage-app` uses Stripe's full-page apps **private developer preview**. You need Stripe to enable the feature flag for your app and account. See [fullpage-app/README.md](./fullpage-app/README.md) for details.

+# Stripe App API
+
+A lightweight Next.js server that provides the `/api/generate` endpoint for AI-powered UI generation in the Stripe App examples.
+
+## Setup

+```bash
+pnpm install

+```
+
+## Running
+
+```bash

+
+Runs on port 3001. The Stripe apps (`drawer-app/` and `fullpage-app/`) expect this server to be running for AI generation features.
+
+## API
+
+### POST /api/generate

+Accepts `{ prompt, systemPrompt }` and returns a streamed text response with a json-render spec.

+# Stripe App (Drawer)
+
+A [Stripe App](https://stripe.com/docs/stripe-apps) example demonstrating how to use json-render to build dynamic, AI-generated UI in the Stripe Dashboard drawer.
+
+## Views
+
+- **Home** - Revenue dashboard with AI-powered UI generation
+- **Customers** - Customer list and management
+- **Customer Details** - Individual customer view
+- **Payments** - Payment list and details
+- **Subscriptions** - Subscription management
+- **Invoices** - Invoice list
+- **Products** - Product catalog
+
+## Setup
+
+```bash
+pnpm install
+
+cp .env.example .env
+# Optionally set STRIPE_APP_ID to your own app ID
+
+pnpm setup
+```
+
+## Running
+
+Start the API server first (from `../api`):
+
+```bash
+cd ../api && pnpm dev
+```
+
+Then start the Stripe app:
+
+```bash
+stripe apps start
+```
+
+## How It Works
+
+1. **Component Catalog** - Maps json-render component types to Stripe UIXT components
+2. **Action Handlers** - Stripe operations (refunds, subscriptions, etc.)
+3. **StripeRenderer** - Custom renderer connecting json-render specs to Stripe components
+4. **Views** - Each view fetches data from the Stripe API and renders it using json-render specs

+# Full Page Stripe App (Alpha)
+
+A full-page [Stripe App](https://stripe.com/docs/stripe-apps) example using json-render. This uses the `FullPageView` component and the `stripe.dashboard.fullpage` viewport, which are part of Stripe's **private developer preview**.
+
+## Prerequisites
+
+- [Stripe CLI](https://stripe.com/docs/stripe-cli) with the apps plugin
+- A Stripe account with **full-page apps alpha access** enabled by Stripe
+- Both your `app_id` and `account_id` must be flagged in by Stripe
+
+## Setup
+
+```bash
+pnpm install
+
+cp .env.example .env
+# Set STRIPE_APP_ID to your app ID
+
+pnpm setup
+```
+
+## Running
+
+Start the API server first (from `../api`):
+
+```bash
+cd ../api && pnpm dev
+```
+
+Then start the Stripe app:
+
+```bash
+stripe apps start
+```
+
+Navigate directly to your full-page app URL (it will not appear in the left navigation):
+
+```
+https://dashboard.stripe.com/test/app/<your-app-id>
+```
+
+## Troubleshooting
+
+If you are redirected to the Dashboard home page, the feature flag is not enabled for your account. Contact your Stripe partner to have both your `app_id` and `account_id` flagged in.
+
+## Resources
+
+- [FullPageView Component](https://docs.stripe.com/stripe-apps/components/fullpageview?app-sdk-version=9)
+- [FullPageTabs Component](https://docs.stripe.com/stripe-apps/components/fullpagetabs?app-sdk-version=9)
