+# @json-render/react-pdf
+
+PDF document renderer. Turn JSON specs into PDFs using `@react-pdf/renderer`.
+
+## Install
+
+```bash
+npm install @json-render/core @json-render/react-pdf
+```
+
+See the [React PDF example](https://github.com/vercel-labs/json-render/tree/main/examples/react-pdf) for a full working example.
+
+## schema
+
+The PDF element schema for document specs. Use with `defineCatalog` from core.
+
+```typescript
+import { defineCatalog } from '@json-render/core';
+import { schema, standardComponentDefinitions } from '@json-render/react-pdf';
+
+const catalog = defineCatalog(schema, {
+  components: standardComponentDefinitions,
+});
+```
+
+## Render Functions
+
+Server-side functions for producing PDF output. All accept a spec and optional `RenderOptions`.
+
+```typescript
+import { renderToBuffer, renderToStream, renderToFile } from '@json-render/react-pdf';
+
+const buffer = await renderToBuffer(spec);
+
+const stream = await renderToStream(spec);
+stream.pipe(res);
+
+await renderToFile(spec, './output.pdf');
+```
+
+### RenderOptions
+
+```typescript
+interface RenderOptions {
+  registry?: ComponentRegistry;
+  includeStandard?: boolean;  // default: true
+  state?: Record<string, unknown>;
+}
+```
+
+<table>
+  <thead>
+    <tr>
+      <th>Option</th>
+      <th>Description</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td><code>registry</code></td>
+      <td>Custom component map (merged with standard components)</td>
+    </tr>
+    <tr>
+      <td><code>includeStandard</code></td>
+      <td>Include built-in standard components (default: <code>true</code>)</td>
+    </tr>
+    <tr>
+      <td><code>state</code></td>
+      <td>Initial state for <code>$state</code> / <code>$cond</code> dynamic prop resolution</td>
+    </tr>
+  </tbody>
+</table>
+
+## defineRegistry
+
+Create a type-safe component registry from a catalog. Components receive `{ props, children, emit, bindings, loading }`.
+
+```tsx
+import { defineRegistry } from '@json-render/react-pdf';
+import { View, Text } from '@react-pdf/renderer';
+
+const { registry } = defineRegistry(catalog, {
+  components: {
+    Badge: ({ props }) => (
+      <View style={{ backgroundColor: props.color ?? '#e5e7eb', padding: 4, borderRadius: 4 }}>
+        <Text style={{ fontSize: 10 }}>{props.label}</Text>
+      </View>
+    ),
+  },
+});
+
+const buffer = await renderToBuffer(spec, { registry });
+```
+
+## createRenderer
+
+Create a standalone renderer component wired to state, actions, and validation.
+
+```typescript
+import { createRenderer } from '@json-render/react-pdf';
+
+const PDFRenderer = createRenderer(catalog, components);
+```
+
+```typescript
+interface CreateRendererProps {
+  spec: Spec | null;
+  state?: Record<string, unknown>;
+  onAction?: (actionName: string, params?: Record<string, unknown>) => void;
+  onStateChange?: (path: string, value: unknown) => void;
+  loading?: boolean;
+  fallback?: ComponentRenderer;
+}
+```
+
+## Renderer
+
+The main component that renders a spec to `@react-pdf/renderer` elements.
+
+```typescript
+interface RendererProps {
+  spec: Spec | null;
+  registry?: ComponentRegistry;
+  includeStandard?: boolean;  // default: true
+  loading?: boolean;
+  fallback?: ComponentRenderer;

 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).
