  "Generate PDF documents using React-PDF library (@react-pdf/renderer). Use when creating PDFs,

Generating PDFs with React-PDF

CRITICAL REQUIREMENTS

1. **Fonts MUST be local files** - Remote font URLs (http/https) do NOT work. Always download fonts to local files before using them. 2. **Wrap async code in IIFE** - Top-level await causes errors. Always use `(async () => { ... })()` pattern. 3. **Disable hyphenation for custom fonts** - Custom fonts lack hyphenation dictionaries and may crash or break words incorrectly. Always call `Font.registerHyphenationCallback((word) => [word]);` after registering custom fonts.

Files

• `references/google-fonts.txt` - Metadata for ~65 popular Google Fonts with TrueType URLs. Each

line is a font variant in tab-separated format: `font name`, `style`, `category`, `weight`, `url`.

• `references/components.md` - Full component API reference and supported CSS properties
• `assets/example-template.tsx` - Minimal working example demonstrating fixed footers, page numbers,

and unbreakable content. Read this before starting to understand the basic patterns. Note: not all APIs are shown here — always refer to the docs and `references/components.md` for the full API.

Prerequisites

npm install react @react-pdf/renderer
npm install -D tsx @types/react

`tsx` runs TypeScript + JSX files directly via Node with no config — no `tsconfig.json` needed. It uses esbuild under the hood and handles JSX transformation automatically.

Core Components

• **Document**: Root component (metadata, settings)
• **Page**: Individual pages (A4, Letter, or custom dimensions)
• **View**: Container component (similar to div)
• **Text**: Text content, supports nesting for inline styling
• **Image**: Embed images (JPG, PNG, base64)
• **Link**: Clickable hyperlinks (external or internal)
• **Note**: Annotation notes
• **Canvas**: Freeform drawing with pdfkit methods
• **Svg**: Vector graphics (Circle, Rect, Path, Line, Polygon, etc.)
• **StyleSheet**: Create reusable styles

For full component props and CSS properties, see [references/components.md](references/components.md).

Basic Example

import React from "react";
import { Document, Page, Text, View, StyleSheet, renderToFile } from "@react-pdf/renderer";

const styles = StyleSheet.create({
  page: { flexDirection: "column", backgroundColor: "#ffffff", padding: 40 },
  title: { fontSize: 24, marginBottom: 20, fontWeight: "bold" },
  text: { fontSize: 12, lineHeight: 1.5 },
});

const MyDocument = () => (
  <Document>
    <Page size="A4" style={styles.page}>
      <View style={{ margin: 10, padding: 20 }}>
        <Text style={styles.title}>Document Title</Text>
        <Text style={styles.text}>Your content here</Text>
      </View>
    </Page>
  </Document>
);

(async () => {
  await renderToFile(<MyDocument />, "./output.pdf");
  console.log("PDF saved!");
})();

Running Scripts

PDF generation scripts use JSX, which Node cannot run directly. Use `tsx` to execute them:

npx tsx my-document.tsx

`npx tsx` works without installing tsx globally — it downloads on demand. If tsx is installed as a dev dependency (`npm install -D tsx`), it runs instantly without the npx download step.

Always wrap rendering in async IIFE:

// Good
(async () => {
  await renderToFile(<MyDocument />, "./output.pdf");
})();

// Bad - top-level await may fail
await renderToFile(<MyDocument />, "./output.pdf");

Previewing PDFs

To visually inspect generated PDFs, convert pages to images. Try `pdftoppm` first (often pre-installed), fall back to Python's PyMuPDF if unavailable.

**Option 1: pdftoppm (poppler-utils)** — preferred, no install needed in many environments:

pdftoppm -png -r 200 document.pdf preview
# → preview-1.png, preview-2.png, ...

**Option 2: PyMuPDF (Python)** — fallback if pdftoppm is not available:

pip install pymupdf

import fitz

doc = fitz.open("document.pdf")
for i, page in enumerate(doc):
    pix = page.get_pixmap(dpi=200)
    pix.save(f"page-{i+1}.png")

Rendering Methods

import { renderToFile, renderToBuffer } from "@react-pdf/renderer";

// To file
(async () => {
  await renderToFile(<MyDocument />, "./document.pdf");
})();

// To buffer
(async () => {
  const buffer = await renderToBuffer(<MyDocument />);
})();

Styling

Three methods: `StyleSheet.create()`, inline objects, or mixed arrays.

const styles = StyleSheet.create({ container: { padding: 20 } });

<View style={styles.container} />
<View style={{ padding: 20 }} />
<View style={[styles.container, { marginTop: 10 }]} />

Supported Units

`pt` (default, 72 DPI), `in`, `mm`, `cm`, `%`, `vw`, `vh`

Common Style Properties

{
  // Flexbox
  flexDirection: "row", justifyContent: "space-between", alignItems: "center",
  flexWrap: "wrap", gap: 10,

  // Box model
  margin: 10, padding: 20, width: "100%", height: 200,

  // Borders
  borderWidth: 1, borderColor: "#333", borderRadius: 5, borderStyle: "solid",

  // Colors
  backgroundColor: "#f0f0f0", color: "#000", opacity: 0.8,

  // Typography
  fontSize: 12, fontWeight: "bold", fontFamily: "Helvetica", fontStyle: "italic",
  lineHeight: 1.5, textAlign: "center", textDecoration: "underline",
  textTransform: "uppercase", letterSpacing: 1,

  // Position
  position: "absolute", top: 0, left: 0, right: 0, bottom: 0, zIndex: 10,

  // Transforms
  transform: "rotate(45deg)", transformOrigin: "center",
}

Images

Local files are most reliable. Remote URLs may fail due to network/CORS issues.

import { Image } from '@react-pdf/renderer';

<Image src="./images/photo.jpg" style={{ width: 200, height: 150 }} />
<Image src={{
