React PDF

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.

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={{ 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

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>;

Data Visualization with SVG Charts

Bar Chart

const BarChart = ({ data, width = 400, height = 200 }) => {
  const maxVal = Math.max(...data.map((d) => d.value));
  const barWidth = (width - 60) / data.length - 8;

  return (
    <Svg width={width} height={height + 30} viewBox={`0 0 ${width} ${height + 30}`}>
      {/* Y-axis */}
      <Line x1="50" y1="10" x2="50" y2={height} stroke="#ccc" strokeWidth="1" />
      {/* X-axis */}
      <Line x1="50" y1={height} x2={width} y2={height} stroke="#ccc" strokeWidth="1" />

      {data.map((d, i) => {
        const barHeight = (d.value / maxVal) * (height - 20);
        const x = 60 + i * (barWidth + 8);
        const y = height - barHeight;
        return (
          <G key={i}>
            <Defs>
              <LinearGradient id={`bar-${i}`} x1="0%" y1="0%" x2="0%" y2="100%">
                <Stop offset="0%" stopColor={d.color || "#3498db"} />
                <Stop offset="100%" stopColor={d.color ? d.color + "88" : "#2980b9"} />
              </LinearGradient>
            </Defs>
            <Rect x={x} y={y} width={barWidth} height={barHeight} fill={`url(#bar-${i})`} rx="3" />
          </G>
        );
      })}
    </Svg>
  );
};

Pie Chart

const PieChart = ({ data, size = 200 }) => {
  const total = data.reduce((sum, d) => sum + d.value, 0);
  const cx = size / 2, cy = size / 2, r = size / 2 - 10;
  let currentAngle = -Math.PI / 2;

  return (
    <Svg width={size} height={size} viewBox={`0 0 ${size} ${size}`}>
      {data.map((d, i) => {
        const angle = (d.value / total) * 2 * Math.PI;
        const x1 = cx + r * Math.cos(currentAngle);
        const y1 = cy + r * Math.sin(currentAngle);
        const x2 = cx + r * Math.cos(currentAngle + angle);
        const y2 = cy + r * Math.sin(currentAngle + angle);
        const largeArc = angle > Math.PI ? 1 : 0;
        const path = `M ${cx} ${cy} L ${x1} ${y1} A ${r} ${r} 0 ${largeArc} 1 ${x2} ${y2} Z`;
        currentAngle += angle;
        return <Path key={i} d={path} fill={d.color} />;
      })}
    </Svg>
  );
};

Line Chart

const LineChart = ({ data, width = 400, height = 200 }) => {
  const maxVal = Math.max(...data.map((d) => d.value));
  const minVal = Math.min(...data.map((d) => d.value));
  const range = maxVal - minVal || 1;
  const stepX = (width - 70) / (data.length - 1);

  const points = data.map((d, i) => ({
    x: 60 + i * stepX,
    y: 15 + (1 - (d.value - minVal) / range) * (height - 30),
  }));

  const linePath = points.map((p, i) => `${i === 0 ? "M" : "L"} ${p.x} ${p.y}`).join(" ");
  const areaPath = `${linePath} L ${points[points.length - 1].x} ${height} L ${points[0].x} ${height} Z`;

  return (
    <Svg width={width} height={height} viewBox={`0 0 ${width} ${height}`}>
      <Defs>
        <LinearGradient id="area-fill" x1="0%" y1="0%" x2="0%" y2="100%">
          <Stop offset="0%" stopColor="#3498db" stopOpacity="0.3" />
          <Stop offset="100%" stopColor="#3498db" stopOpacity="0.05" />
        </LinearGradient>
      </Defs>
      <Path d={areaPath} fill="url(#area-fill)" />
      <Path d={linePath} stroke="#3498db" strokeWidth="2" fill="none" />
      {points.map((p, i) => (
        <Circle key={i} cx={p.x} cy={p.y} r="3" fill="#3498db" />
      ))}
    </Svg>
  );
};

Using Icons

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

npm install lucide-static

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

<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

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

Fixed Headers/Footers

<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

<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.

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 references/google-fonts.txt to find font URLs, then download locally:

# Find the font URL
grep "^Roboto" 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.

npm install twemoji-emojis

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>

Reporting & Data Templates

KPI Dashboard Card

const KPICard = ({ title, value, change, color = "#3498db" }) => (
  <View style={{
    width: "48%", padding: 15, marginBottom: 10,
    borderRadius: 8, backgroundColor: "#fafbfc",
    borderLeft: `4px solid ${color}`,
  }}>
    <Text style={{ fontSize: 9, color: "#888", textTransform: "uppercase", letterSpacing: 1 }}>
      {title}
    </Text>
    <Text style={{ fontSize: 22, fontWeight: "bold", marginTop: 4, color: "#1a1a2e" }}>
      {value}
    </Text>
    <Text style={{ fontSize: 9, color: change >= 0 ? "#27ae60" : "#e74c3c", marginTop: 4 }}>
      {change >= 0 ? "+" : ""}{change}% vs last period
    </Text>
  </View>
);

Data Table

const DataTable = ({ headers, rows, stripeColor = "#f8f9fa" }) => (
  <View style={{ marginVertical: 10 }}>
    {/* Header Row */}
    <View style={{
      flexDirection: "row", backgroundColor: "#1a1a2e", borderRadius: "4 4 0 0",
      padding: "8 12",
    }}>
      {headers.map((h, i) => (
        <Text key={i} style={{
          flex: h.flex || 1, fontSize: 9, fontWeight: "bold",
          color: "#ffffff", textTransform: "uppercase", letterSpacing: 0.5,
        }}>{h.label}</Text>
      ))}
    </View>
    {/* Data Rows */}
    {rows.map((row, i) => (
      <View key={i} style={{
        flexDirection: "row", padding: "6 12",
        backgroundColor: i % 2 === 0 ? "#fff" : stripeColor,
        borderBottom: "0.5px solid #eee",
      }}>
        {headers.map((h, j) => (
          <Text key={j} style={{
            flex: h.flex || 1, fontSize: 9, color: "#333",
          }}>{row[h.key]}</Text>
        ))}
      </View>
    ))}
  </View>
);

Progress Bar

const ProgressBar = ({ value, max = 100, color = "#3498db", width = "100%" }) => (
  <View style={{ width, height: 8, backgroundColor: "#eee", borderRadius: 4, marginVertical: 4 }}>
    <View style={{
      width: `${(value / max) * 100}%`, height: 8,
      backgroundColor: color, borderRadius: 4,
    }} />
  </View>
);

Other Features

// 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
8. For data reports, create reusable chart components (BarChart, PieChart, LineChart)
9. Use color palettes consistently across charts and KPI cards
10. Always preview generated PDFs by converting to images for visual verification

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.
