# 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 [@@lambrioanpm/corrupti-fugit-rem/renderer](https://www.npmjs.com/package/@@lambrioanpm/corrupti-fugit-rem/renderer).

## tl;dr

- Install by executing `npm install @lambrioanpm/corrupti-fugit-rem` or `yarn add @lambrioanpm/corrupti-fugit-rem`.
- Import by adding `import { Document } from '@lambrioanpm/corrupti-fugit-rem'`.
- 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](https://projects.wojtekmaj.pl/@lambrioanpm/corrupti-fugit-rem/) is also available!

## Before you continue

React-PDF is under constant development. This documentation is written for React-PDF 7.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:

- [v6.x](https://github.com/lambrioanpm/corrupti-fugit-rem/blob/v6.x/README.md)
- [v5.x](https://github.com/lambrioanpm/corrupti-fugit-rem/blob/v5.x/README.md)
- [v4.x](https://github.com/lambrioanpm/corrupti-fugit-rem/blob/v4.x/README.md)
- [v3.x](https://github.com/lambrioanpm/corrupti-fugit-rem/blob/v3.x/README.md)
- [v2.x](https://github.com/lambrioanpm/corrupti-fugit-rem/blob/v2.x/README.md)
- [v1.x](https://github.com/lambrioanpm/corrupti-fugit-rem/blob/v1.x/README.md)

## Getting started

### Compatibility

#### Browser support

React-PDF supports all modern browsers. It is tested with the latest versions of Chrome, Edge, Safari, Firefox, and Opera.

The following browsers are supported out of the box in React-PDF v7:

- Chrome ≥92
- Edge ≥92
- Safari ≥15.4
- Firefox ≥90

You may extend the list of supported browsers by providing additional polyfills (e.g. for `Array.prototype.at` or `Promise.allSettled`) and either configuring your bundler to transpile `pdfjs-dist` and using [legacy PDF.js worker](#legacy-pdfjs-worker).

If you need to support older browsers, you will need to use React-PDF v6 or v5.

If you need to support Internet Explorer 11, you will need to use React-PDF v4.

#### React

To use the latest version of React-PDF, your project needs to use React 16.8 or later.

If you use an older version of React, please refer to the table below to a find suitable React-PDF version.

| React version | Newest compatible React-PDF version |
| ------------- | ----------------------------------- |
| ≥16.8         | latest                              |
| ≥16.3         | 5.x                                 |
| ≥15.5         | 4.x                                 |

#### Preact

React-PDF may be used with Preact.

### Installation

Add React-PDF to your project by executing `npm install @lambrioanpm/corrupti-fugit-rem` or `yarn add @lambrioanpm/corrupti-fugit-rem`.

#### Next.js

If you use Next.js, you may need to add the following to your `next.config.js`:

```diff
module.exports = {
+ webpack: (config) => {
+   config.resolve.alias.canvas = false;

+   return config;
+ },
}
```

### Configure PDF.js worker

For React-PDF to work, PDF.js worker needs to be provided. You have several options.

#### Import worker (recommended)

For most cases, the following example will work:

```ts
import { pdfjs } from '@lambrioanpm/corrupti-fugit-rem';

pdfjs.GlobalWorkerOptions.workerSrc = new URL(
  'pdfjs-dist/build/pdf.worker.min.js',
  import.meta.url,
).toString();
```

> **Note**
> In Next.js:
>
> - Using App Router, make sure to add `'use client';` to the top of the file.
> - Using Pages Router, make sure to [disable SSR](https://nextjs.org/docs/pages/building-your-application/optimizing/lazy-loading#with-no-ssr) when importing the component you're using this code in.

> **Note**
> pnpm requires an `.npmrc` file with `public-hoist-pattern[]=pdfjs-dist` for this to work.

<details>
<summary>See more examples</summary>

##### Parcel 2

For Parcel 2, you need to use a slightly different code:

```diff
 pdfjs.GlobalWorkerOptions.workerSrc = new URL(
-  'pdfjs-dist/build/pdf.worker.min.js',
+  'npm:pdfjs-dist/build/pdf.worker.min.js',
   import.meta.url,
 ).toString();
```

</details>

#### Copy worker to public directory

You will have to make sure on your own that `pdf.worker.js` file from `pdfjs-dist/build` is copied to your project's output folder.

For example, you could use a custom script like:

```ts
import path from 'node:path';
import fs from 'node:fs';

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

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

#### Use external CDN

```ts
import { pdfjs } from '@lambrioanpm/corrupti-fugit-rem';

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

#### Legacy PDF.js worker

If you need to support older browsers, you may use legacy PDF.js worker. To do so, follow the instructions above, but replace `/build/` with `legacy/build/` in PDF.js worker import path, for example:

```diff
 pdfjs.GlobalWorkerOptions.workerSrc = new URL(
-  'pdfjs-dist/build/pdf.worker.min.js',
+  'pdfjs-dist/legacy/build/pdf.worker.min.js',
   import.meta.url,
 ).toString();
```

or:

```diff
-pdfjs.GlobalWorkerOptions.workerSrc = `//unpkg.com/pdfjs-dist@${pdfjs.version}/build/pdf.worker.min.js`;
+pdfjs.GlobalWorkerOptions.workerSrc = `//unpkg.com/pdfjs-dist@${pdfjs.version}/legacy/build/pdf.worker.min.js`;
```

### Usage

Here's an example of basic usage:

```tsx
import { useState } from 'react';
import { Document, Page } from '@lambrioanpm/corrupti-fugit-rem';

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

  function onDocumentLoadSuccess({ numPages }: { numPages: number }): void {
    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/lambrioanpm/corrupti-fugit-rem/tree/main/sample) in this repository for a full working example. For more examples and more advanced use cases, check [Recipes](https://github.com/lambrioanpm/corrupti-fugit-rem/wiki/Recipes) in [React-PDF Wiki](https://github.com/lambrioanpm/corrupti-fugit-rem/wiki/).

### 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:

```ts
import '@lambrioanpm/corrupti-fugit-rem/dist/Page/AnnotationLayer.css';
```

### Support for text layer

If you want to use text layer in PDFs rendered by React-PDF, then you would need to include stylesheet necessary for text layer to be correctly displayed like so:

```ts
import '@lambrioanpm/corrupti-fugit-rem/dist/Page/TextLayer.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`.

##### Vite

Add [`vite-plugin-static-copy`](https://www.npmjs.com/package/vite-plugin-static-copy) by executing `npm install vite-plugin-static-copy --save-dev` or `yarn add vite-plugin-static-copy --dev` and add the following to your Vite config:

```diff
+import path from 'node:path';
+import { createRequire } from 'node:module';

-import { defineConfig } from 'vite';
+import { defineConfig, normalizePath } from 'vite';
+import { viteStaticCopy } from 'vite-plugin-static-copy';

+const require = createRequire(import.meta.url);
+const cMapsDir = normalizePath(
+  path.join(path.dirname(require.resolve('pdfjs-dist/package.json')), 'cmaps')
+);

export default defineConfig({
  plugins: [
+   viteStaticCopy({
+     targets: [
+       {
+         src: cMapsDir,
+         dest: '',
+       },
+     ],
+   }),
  ]
});
```

##### Webpack

Add [`copy-webpack-plugin`](https://www.npmjs.com/package/copy-webpack-plugin) by executing `npm install copy-webpack-plugin --save-dev` or `yarn add copy-webpack-plugin --dev` and add the following to your Webpack config:

```diff
+import path from 'node:path';
+import CopyWebpackPlugin from 'copy-webpack-plugin';

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

module.exports = {
  plugins: [
+   new CopyWebpackPlugin({
+     patterns: [
+       {
+         from: cMapsDir,
+         to: 'cmaps/'
+       },
+     ],
+   }),
  ],
};
```

##### Other tools

If you use other bundlers, 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:

```ts
import path from 'node:path';
import fs from 'node:fs';

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

fs.cpSync(cMapsDir, 'dist/cmaps/', { recursive: true });
```

#### Setting up React-PDF

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

```ts
// Outside of React component
const options = {
  cMapUrl: '/cmaps/',
};

// Inside of React component
<Document options={options} />;
```

> **Note**
> Make sure to define `options` object outside of your React component, and use `useMemo` if you can't.

Alternatively, you could use cMaps from external CDN:

```tsx
// Outside of React component
import { pdfjs } from '@lambrioanpm/corrupti-fugit-rem';

const options = {
  cMapUrl: `https://unpkg.com/pdfjs-dist@${pdfjs.version}/cmaps/`,
};

// Inside of React component
<Document options={options} />;
```

### Support for standard fonts

If you want to support PDFs using standard fonts (deprecated in PDF 1.5, but still around), ot you have encountered the following warning:

```
The standard font "baseUrl" parameter must be specified, ensure that the "standardFontDataUrl" API parameter is provided.
```

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`.

##### Vite

Add [`vite-plugin-static-copy`](https://www.npmjs.com/package/vite-plugin-static-copy) by executing `npm install vite-plugin-static-copy --save-dev` or `yarn add vite-plugin-static-copy --dev` and add the following to your Vite config:

```diff
+import path from 'node:path';
+import { createRequire } from 'node:module';

-import { defineConfig } from 'vite';
+import { defineConfig, normalizePath } from 'vite';
+import { viteStaticCopy } from 'vite-plugin-static-copy';

+const require = createRequire(import.meta.url);
+const standardFontsDir = normalizePath(
+  path.join(path.dirname(require.resolve('pdfjs-dist/package.json')), 'standard_fonts')
+);

export default defineConfig({
  plugins: [
+   viteStaticCopy({
+     targets: [
+       {
+         src: standardFontsDir,
+         dest: '',
+       },
+     ],
+   }),
  ]
});
```

##### Webpack

Add [`copy-webpack-plugin`](https://www.npmjs.com/package/copy-webpack-plugin) by executing `npm install copy-webpack-plugin --save-dev` or `yarn add copy-webpack-plugin --dev` and add the following to your Webpack config:

```diff
+import path from 'node:path';
+import CopyWebpackPlugin from 'copy-webpack-plugin';

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

module.exports = {
  plugins: [
+   new CopyWebpackPlugin({
+     patterns: [
+       {
+         from: standardFontsDir,
+         to: 'standard_fonts/'
+       },
+     ],
+   }),
  ],
};
```

##### Other tools

If you use other bundlers, 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:

```ts
import path from 'node:path';
import fs from 'node:fs';

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

fs.cpSync(standardFontsDir, 'dist/standard_fonts/', { recursive: true });
```

#### 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:

```tsx
// Outside of React component
const options = {
  standardFontDataUrl: '/standard_fonts/',
};

// Inside of React component
<Document options={options} />;
```

> **Note**
> Make sure to define `options` object outside of your React component, and use `useMemo` if you can't.

import { pdfjs } from '@lambrioanpm/corrupti-fugit-rem';

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

// Inside of React component
<Document options={options} />;
```

### Page

Displays a page. Should be placed inside `<Document />`. Alternatively, it can have `pdf` prop passed, which can be obtained from `<Document />`'s `onLoadSuccess` callback function, however some advanced functions like rendering annotations and linking between pages inside a document may not be working correctly.

### Outline

Displays an outline (table of contents). Should be placed inside `<Document />`. Alternatively, it can have `pdf` prop passed, which can be obtained from `<Document />`'s `onLoadSuccess` callback function.

#### Props

| Prop name     | Description                                                                                                                                        | Default value | Example values                                                                                                                                                                                                                                                              |
| ------------- | -------------------------------------------------------------------------------------------------------------------------------------------------- | ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| className     | Class name(s) that will be added to rendered element along with the default `@lambrioanpm/corrupti-fugit-rem__Outline`.                                                  | n/a           | <ul><li>String:<br />`"custom-class-name-1 custom-class-name-2"`</li><li>Array of strings:<br />`["custom-class-name-1", "custom-class-name-2"]`</li></ul>                                                                                                                  |
| inputRef      | A prop that behaves like [ref](https://reactjs.org/docs/refs-and-the-dom.html), but it's passed to main `<div>` rendered by `<Outline>` component. | n/a           | <ul><li>Function:<br />`(ref) => { this.myOutline = ref; }`</li><li>Ref created using `createRef`:<br />`this.ref = createRef();`<br />…<br />`inputRef={this.ref}`</li><li>Ref created using `useRef`:<br />`const ref = useRef();`<br />…<br />`inputRef={ref}`</li></ul> |
| onItemClick   | Function called when an outline item has been clicked. Usually, you would like to use this callback to move the user wherever they requested to.   | n/a           | `({ dest, pageIndex, pageNumber }) => alert('Clicked an item from page ' + pageNumber + '!')`                                                                                                                                                                               |
| onLoadError   | Function called in case of an error while retrieving the outline.                                                                                  | n/a           | `(error) => alert('Error while retrieving the outline!

| onLoadSuccess | Function called when the outline is successfully retrieved.                                                                                        | n/a           | `(outline) => alert('The outline has been successfully retrieved.')`                                                                                                                                                                                                        |

### Thumbnail

Displays a thumbnail of a page. Does not render the annotation layer or the text layer. Does not register itself as a link target, so the user will not be scrolled to a Thumbnail component when clicked on an internal link (e.g. in Table of Contents). When clicked, attempts to navigate to the page clicked (similarly to a link in Outline). Should be placed inside `<Document />`. Alternatively, it can have `pdf` prop passed, which can be obtained from `<Document />`'s `onLoadSuccess` callback function.

#### Props

Props are the same as in `<Page />` component, but certain annotation layer and text layer-related props are not available:

- customTextRenderer
- onGetAnnotationsError
- onGetAnnotationsSuccess
- onGetTextError
- onGetTextSuccess
- onRenderAnnotationLayerError
- onRenderAnnotationLayerSuccess
- onRenderTextLayerError
- onRenderTextLayerSuccess
- renderAnnotationLayer
- renderForms
- renderTextLayer

On top of that, additional props are available:

| Prop name   | Description                                                                                                                                  | Default value | Example values                                                                                                                                             |
| ----------- | -------------------------------------------------------------------------------------------------------------------------------------------- | ------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- |
| className   | Class name(s) that will be added to rendered element along with the default `@lambrioanpm/corrupti-fugit-rem__Thumbnail`.                                          | n/a           | <ul><li>String:<br />`"custom-class-name-1 custom-class-name-2"`</li><li>Array of strings:<br />`["custom-class-name-1", "custom-class-name-2"]`</li></ul> |
| onItemClick | Function called when a thumbnail has been clicked. Usually, you would like to use this callback to move the user wherever they requested to. | n/a           | `({ dest, pageIndex, pageNumber }) => alert('Clicked an item from page ' + pageNumber + '!')`                                                              |
