react-pdf

Generates PDF documents using the React-PDF library (@react-pdf/renderer) with TypeScript and JSX. Use when creating PDFs, generating reports, invoices, forms, resumes, or any document that needs flexbox layout, SVG graphics, custom fonts, or professional typesetting. Prefer over Python PDF libraries (ReportLab, fpdf2) when layout complexity matters.

  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 3 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by trailofbits on GitHub. Read the source before you install it.

Installation

Install the React Pdf AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/trailofbits/skills-curated/tree/main/plugins/react-pdf/skills/react-pdf
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/trailofbits/skills-curated.git /tmp/skills-curated
mkdir -p .claude/skills
cp -r /tmp/skills-curated/plugins/react-pdf/skills/react-pdf .claude/skills/react-pdf
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable React Pdf in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads React Pdf on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so React Pdf is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Generating PDFs with React-PDF

When to Use

  • Generating PDF documents (reports, invoices, resumes, forms, certificates)
  • Creating PDFs that need complex layouts (multi-column, grids, cards)
  • Building PDFs with inline SVG graphics, charts, or icons
  • Producing documents with custom Google Fonts or emoji
  • Any PDF task where flexbox layout is easier than absolute coordinate math

When NOT to Use

  • Reading or extracting text from existing PDFs — use pdfplumber or pypdf instead
  • Filling existing PDF forms — use Python pypdf or pdftk
  • Converting HTML to PDF — use Playwright or WeasyPrint instead
  • Simple one-off text PDFs with no layout needs — a Python script may be simpler

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

  • {baseDir}/skills/react-pdf/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.
  • {baseDir}/skills/react-pdf/references/components.md - Full component API reference and supported CSS properties
  • {baseDir}/skills/react-pdf/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 {baseDir}/skills/react-pdf/references/components.md for the full API.

Prerequisites

bash
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.

Basic Example

tsx
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:

bash
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:

tsx
// 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:

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

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

bash
pip install pymupdf
python
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

tsx
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.

tsx
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

tsx
{
  // 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.

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

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

SVG files cannot be used as Image sources. Read the SVG source and recreate using react-pdf Svg components.

SVG Graphics

tsx
import { Svg, Circle, Rect, Path, Line, G, Defs, LinearGradient, Stop } from "@react-pdf/renderer";

<Svg width="200" height="200" viewBox="0 0 200 200">
  <Defs>
    <LinearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
      <Stop offset="0%" stopColor="#3498db" />
      <Stop offset="100%" stopColor="#9b59b6" />
    </LinearGradient>
  </Defs>
  <Circle cx="100" cy="100" r="50" fill="url(#grad1)" />
  <Rect x="10" y="10" width="50" height="50" fill="#e74c3c" />
  <Path d="M10,50 Q50,10 90,50" stroke="#2ecc71" strokeWidth="2" fill="none" />
</Svg>;

Using Icons

Read SVG source from icon libraries and convert to react-pdf Svg components:

bash
npm install lucide-static
tsx
import { Svg, Path, Rect } from "@react-pdf/renderer";

// Converted from lucide-static/icons/mail.svg
const MailIcon = ({ size = 12, color = "#888" }) => (
  <Svg width={size} height={size} viewBox="0 0 24 24">
    <Path d="m22 7-8.991 5.727a2 2 0 0 1-2.009 0L2 7" stroke={color} strokeWidth={2} fill="none" />
    <Rect x="2" y="4" width="20" height="16" rx="2" stroke={color} strokeWidth={2} fill="none" />
  </Svg>
);

Links and Navigation

tsx
<Link src="https://example.com"><Text>Visit website</Text></Link>

<View id="section-1"><Text>Target</Text></View>
<Link src="#section-1"><Text>Jump to Section 1</Text></Link>

Dynamic Content and Page Numbers

tsx
<Text render={({ pageNumber, totalPages }) => `Page ${pageNumber} of ${totalPages}`} />

Fixed Headers/Footers

tsx
<Page size="A4">
  <View fixed style={{ position: "absolute", top: 20, left: 30, right: 30 }}>
    <Text>Header</Text>
  </View>
  <View style={{ marginTop: 60, marginBottom: 60 }}>
    <Text>Content</Text>
  </View>
  <Text
    fixed
    style={{ position: "absolute", bottom: 20, left: 30, right: 30, textAlign: "center" }}
    render={({ pageNumber, totalPages }) => `Page ${pageNumber} of ${totalPages}`}
  />
</Page>

Page Breaks and Wrapping

tsx
<View break />                              // Force page break
<View wrap={false}><Text>Keep together</Text></View>  // Prevent breaking inside
<Text orphans={2} widows={2}>Long text...</Text>       // Orphan/widow control
<View minPresenceAhead={100}><Text>Content</Text></View>  // Min space before break

Custom Fonts

CRITICAL: All font sources MUST be local file paths. Remote URLs do not work.

tsx
import { Font } from "@react-pdf/renderer";

Font.register({
  family: "Roboto",
  fonts: [
    { src: "./fonts/Roboto-Regular.ttf", fontWeight: "normal" },
    { src: "./fonts/Roboto-Bold.ttf", fontWeight: "bold" },
    { src: "./fonts/Roboto-Italic.ttf", fontStyle: "italic" },
  ],
});

// Always disable hyphenation when using custom fonts
Font.registerHyphenationCallback((word) => [word]);

Built-in fonts: Courier, Helvetica, Times-Roman (each with Bold, Italic/Oblique variants)

Font weight values: thin (100), ultralight (200), light (300), normal (400), medium (500), semibold (600), bold (700), ultrabold (800), heavy (900)

Google Fonts

Use {baseDir}/skills/react-pdf/references/google-fonts.txt to find font URLs, then download locally:

bash
# Find the font URL
grep "^Roboto" {baseDir}/skills/react-pdf/references/google-fonts.txt | grep "700" | grep "normal"

# Download
mkdir -p fonts
curl -sL "<url-from-grep>" -o fonts/Roboto-Bold.ttf

# Verify - must show "TrueType Font data"
file fonts/Roboto-Bold.ttf

If file shows "HTML document" or "ASCII text", the download failed. Try a different URL or search GitHub for the font's official repo with TTF files.

Emoji

Emoji won't render in PDFs unless you register an emoji source. Install twemoji-emojis to get local Twemoji PNG assets — no internet needed at render time.

bash
npm install twemoji-emojis
tsx
import { Font } from "@react-pdf/renderer";

Font.registerEmojiSource({
  format: "png",
  url: "node_modules/twemoji-emojis/vendor/72x72/",
});

Then use emoji directly in Text: <Text>Hello</Text>

Other Features

tsx
// Canvas drawing
<Canvas style={{ width: 200, height: 200 }}
  paint={(painter, w, h) => { painter.circle(w/2, h/2, 50).fill("#3498db"); }} />

// Annotation notes
<Note style={{ color: "yellow" }}>Annotation text</Note>

// Hyphenation
Font.registerHyphenationCallback((word) => [word]); // disable

// Debug mode - visualize boundaries
<View debug><Text debug>Debug text</Text></View>

// Document metadata
<Document title="My Doc" author="Author" subject="Report" language="en-US" pdfVersion="1.5" />

Best Practices

  1. Use StyleSheet.create() — define styles once and reuse
  2. Compress images before embedding, use cache={true} for remote images
  3. Test page breaks — content may flow differently than expected
  4. Prefer flexbox over absolute positioning
  5. Use fixed prop for headers/footers on every page
  6. Use debug={true} to visualize element boundaries
  7. Wrap rendering in try-catch blocks

Common Issues

Text overflow: <Text style={{ width: 200, maxLines: 3, textOverflow: "ellipsis" }}>...</Text>

Missing fonts: Download locally and register with local file paths. Remote URLs will NOT work.

Unexpected page breaks: Use wrap={false} to keep content together, or <View break /> to force breaks.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the React Pdf AI skill do?

Generates PDF documents using the React-PDF library (@react-pdf/renderer) with TypeScript and JSX. Use when creating PDFs, generating reports, invoices, forms, resumes, or any document that needs flexbox layout, SVG graphics, custom fonts, or professional typesetting. Prefer over Python PDF libraries (ReportLab, fpdf2) when layout complexity matters.

Why use React Pdf on TypingMind?

Because you install it once and use it with any model. React Pdf is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install React Pdf in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/trailofbits/skills-curated/tree/main/plugins/react-pdf/skills/react-pdf. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use React Pdf?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with React Pdf?

As many as you like. As long as a model supports skills, you can use React Pdf with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the React Pdf AI skill free?

Yes. It is published on GitHub by trailofbits under the CC-BY-SA-4.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
