# React-PDF

Display PDFs in your React app as easily as if they were images.

## Lost?

This package is used to _display_ existing PDFs. If you wish to _create_ PDFs using React, you may be looking for [@react-pdf/renderer](https://github.com/diegomura/react-pdf).

## tl;dr

- Install by executing `npm install react-pdf` or `yarn add react-pdf`.
- Import by adding `import { Document } from 'react-pdf'`.
- Use by adding `<Document file="..." />`. `file` can be a URL, base64 content, Uint8Array, and more.
- Put `<Page />` components inside `<Document />` to render pages.

## Demo

A minimal demo page can be found in `sample` directory.

[Online demo](http://projects.wojtekmaj.pl/react-pdf/) is also available!

## Before you continue

React-PDF is under constant development. This documentation is written for React-PDF 5.x branch. If you want to see documentation for other versions of React-PDF, use dropdown on top of GitHub page to switch to an appropriate tag. Here are quick links to the newest docs from each branch:

- [v4.x](https://github.com/wojtekmaj/react-pdf/blob/v4.x/README.md)
- [v3.x](https://github.com/wojtekmaj/react-pdf/blob/v3.x/README.md)
- [v2.x](https://github.com/wojtekmaj/react-pdf/blob/v2.x/README.md)
- [v1.x](https://github.com/wojtekmaj/react-pdf/blob/v1.8.3/README.md)

## Getting started

### Compatibility

#### React

To use the latest version of React-PDF, your project needs to use React 16.3 or later.

If you use an older version of React, please refer to the table below to a find suitable React-PDF version. Don't worry - as long as you're running React 15.5 or later, you won't be missing out a lot!

| React version | Newest compatible React-PDF version |
| ------------- | ----------------------------------- |
| ≥16.3         | latest                              |
| ≥15.5         | 4.x                                 |

#### Internet Explorer

Internet Explorer is not supported in React-PDF 5.x or later. If you need Internet Explorer support, you will need to use React-PDF 4.x instead. Don't worry - it still receives bug fixes and even occasional small features!

### Installation

Add React-PDF to your project by executing `npm install react-pdf` or `yarn add react-pdf`.

### Usage

Here's an example of basic usage:

```js
import React, { useState } from 'react';
import { Document, Page } from 'react-pdf';

function MyApp() {
  const [numPages, setNumPages] = useState(null);
  const [pageNumber, setPageNumber] = useState(1);

  function onDocumentLoadSuccess({ numPages }) {
    setNumPages(numPages);
  }

  return (
    <div>
      <Document file="somefile.pdf" onLoadSuccess={onDocumentLoadSuccess}>
        <Page pageNumber={pageNumber} />
      </Document>
      <p>
        Page {pageNumber} of {numPages}
      </p>
    </div>
  );
}
```

Check the [sample directory](https://github.com/wojtekmaj/react-pdf/tree/main/sample) in this repository for a full working example. For more examples and more advanced use cases, check [Recipes](https://github.com/wojtekmaj/react-pdf/wiki/Recipes) in [React-PDF Wiki](https://github.com/wojtekmaj/react-pdf/wiki/).

### Configure PDF.js worker

For React-PDF to work, PDF.js worker needs to be provided.

To make it easier, special entry files were prepared for most popular bundlers. You can find them in the table below.

For example, if you want to use React-PDF with Webpack 5, instead of writing:

```js
import { Document, Page } from 'react-pdf';
```

write:

```js
import { Document, Page } from 'react-pdf/dist/esm/entry.webpack';
```

| Bundler   | Entry file                          |
| --------- | ----------------------------------- |
| Parcel 1  | `react-pdf/dist/esm/entry.parcel`   |
| Parcel 2  | `react-pdf/dist/esm/entry.parcel2`  |
| Webpack 4 | `react-pdf/dist/esm/entry.webpack`  |
| Webpack 5 | `react-pdf/dist/esm/entry.webpack5` |

#### Create React App

Create React App 4 (`react-scripts@4.0.0`) uses Webpack 4 under the hood, so you can use the entry file built for Webpack 4.

Create React App 5 (`react-scripts@5.0.0`) uses Webpack 5 under the hood, so the aim is to use the entry file built for Webpack 5. However, the way Webpack is configured in CRA 5 causes it to crash at build time on most machines with _JavaScript heap out of memory_ error.

[Standard instructions](#standard-browserify-esbuild-and-others) will also work with Create React App. Please note that in CRA, you can copy `pdf.worker.js` file from `pdfjs-dist/legacy/build` to `public` directory in order for it to be copied to your project's output folder at build time.

#### Standard (Browserify, esbuild and others)

If you use Browserify, esbuild, or other bundlers, you will have to make sure on your own that `pdf.worker.js` file from `pdfjs-dist/legacy/build` is copied to your project's output folder.

For example, you could use a custom script like:

```js
import path from 'path';
import fs from 'fs';

const pdfjsDistPath = path.dirname(require.resolve('pdfjs-dist/package.json'));
const pdfWorkerPath = path.join(pdfjsDistPath, 'legacy', 'build', 'pdf.worker.js');

fs.copyFileSync(pdfWorkerPath, './dist/pdf.worker.js');
```

If you don't need to debug `pdf.worker.js`, you can use `pdf.worker.min.js` file instead, which is roughly half the size. For this to work, however, you will need to specify `workerSrc` manually like so:

```js
import { pdfjs } from 'react-pdf';
pdfjs.GlobalWorkerOptions.workerSrc = 'pdf.worker.min.js';
```

Alternatively, you could use the minified `pdf.worker.min.js` from an external CDN:

```js
import { pdfjs } from 'react-pdf';
pdfjs.GlobalWorkerOptions.workerSrc = `//unpkg.com/pdfjs-dist@${pdfjs.version}/legacy/build/pdf.worker.min.js`;
```

### Support for annotations

If you want to use annotations (e.g. links) in PDFs rendered by React-PDF, then you would need to include stylesheet necessary for annotations to be correctly displayed like so:

```js
import 'react-pdf/dist/esm/Page/AnnotationLayer.css';
```

### Support for non-latin characters

If you want to ensure that PDFs with non-latin characters will render perfectly, or you have encountered the following warning:

```
Warning: The CMap "baseUrl" parameter must be specified, ensure that the "cMapUrl" and "cMapPacked" API parameters are provided.
```

then you would also need to include cMaps in your build and tell React-PDF where they are.

#### Copying cMaps

First, you need to copy cMaps from `pdfjs-dist` (React-PDF's dependency - it should be in your `node_modules` if you have React-PDF installed). cMaps are located in `pdfjs-dist/cmaps`.

##### Webpack

Add `copy-webpack-plugin` to your project if you haven't already:

```
npm install copy-webpack-plugin --save-dev
```

Now, in your Webpack config, import the plugin:

```js
import path from 'path';
import CopyWebpackPlugin from 'copy-webpack-plugin';
```

and in `plugins` section of your config, add the following:

```js
new CopyWebpackPlugin({
  patterns: [
    {
      from: path.join(path.dirname(require.resolve('pdfjs-dist/package.json')), 'cmaps'),
      to: 'cmaps/'
    },
  ],
}),
```

##### Parcel, Browserify and others

If you use Parcel, Browserify or other bundling tools, you will have to make sure on your own that cMaps are copied to your project's output folder.

For example, you could use a custom script like:

```js
import path from 'path';
import fs from 'fs';

const cMapsDir = path.join(path.dirname(require.resolve('pdfjs-dist/package.json')), 'cmaps');

function copyDir(from, to) {
  // Ensure target directory exists
  fs.mkdirSync(to, { recursive: true });

  const files = fs.readdirSync(from);
  files.forEach((file) => {
    fs.copyFileSync(path.join(from, file), path.join(to, file));
  });
}

copyDir(cMapsDir, 'dist/cmaps/');
```

#### Setting up React-PDF

Now that you have cMaps in your build, pass required options to Document component by using `options` prop, like so:

```js
<Document
  options={{
    cMapUrl: 'cmaps/',
    cMapPacked: true,
  }}
/>
```

Alternatively, you could use cMaps from external CDN:

```js
import { pdfjs } from 'react-pdf';

<Document
  options={{
    cMapUrl: `https://unpkg.com/pdfjs-dist@${pdfjs.version}/cmaps/`,
    cMapPacked: true,
  }}
/>;
```

### Support for standard fonts

If you want to support PDFs using standard fonts (deprecated in PDF 1.5, but still around), then you would also need to include standard fonts in your build and tell React-PDF where they are.

#### Copying fonts

First, you need to copy standard fonts from `pdfjs-dist` (React-PDF's dependency - it should be in your `node_modules` if you have React-PDF installed). Standard fonts are located in `pdfjs-dist/standard_fonts`.

##### Webpack

Add `copy-webpack-plugin` to your project if you haven't already:

```
npm install copy-webpack-plugin --save-dev
```

Now, in your Webpack config, import the plugin:

```js
import path from 'path';
import CopyWebpackPlugin from 'copy-webpack-plugin';
```

and in `plugins` section of your config, add the following:

```js
new CopyWebpackPlugin({
  patterns: [
    {
      from: path.join(path.dirname(require.resolve('pdfjs-dist/package.json')), 'standard_fonts'),
      to: 'standard_fonts/'
    },
  ],
}),
```

##### Parcel, Browserify and others

If you use Parcel, Browserify or other bundling tools, you will have to make sure on your own that standard fonts are copied to your project's output folder.

For example, you could use a custom script like:

```js
import path from 'path';
import fs from 'fs';

const standardFontsDir = path.join(
  path.dirname(require.resolve('pdfjs-dist/package.json')),
  'standard_fonts',
);

function copyDir(from, to) {
  // Ensure target directory exists
  fs.mkdirSync(to, { recursive: true });

  const files = fs.readdirSync(from);
  files.forEach((file) => {
    fs.copyFileSync(path.join(from, file), path.join(to, file));
  });
}

copyDir(standardFontsDir, 'dist/standard_fonts/');
```

#### Setting up React-PDF

Now that you have standard fonts in your build, pass required options to Document component by using `options` prop, like so:

```js
<Document
  options={{
    standardFontDataUrl: 'standard_fonts/',
  }}
/>
```

Alternatively, you could use standard fonts from external CDN:

```js
import { pdfjs } from 'react-pdf';

<Document
  options={{
    standardFontDataUrl: `https://unpkg.com/pdfjs-dist@${pdfjs.version}/standard_fonts`,
  }}
/>;
```
