# @react-league/react-file-previewer

A browser/device-agnostic file previewer for PDF and image file types built on top of React-PDF.

## Installation

```
npm i @react-league/react-file-previewer
```

## Usage

This component supports URLs and base64 encoded data.

### Basic Usage

```javascript
import FilePreviewer from '@react-league/react-file-previewer';

export const App = () => (
    <div>
        <h1>My App</h1>
        <FilePreviewer file={{
            url: "https://cors-anywhere.herokuapp.com/http://africau.edu/images/default/sample.pdf"}}
        />
    </div>
);
```

### Base64 Usage

```javascript
import FilePreviewer from '@react-league/react-file-previewer';

export const App = () => (
    <div>
        <h1>My App</h1>
        <FilePreviewer
            file={{
                data: "<base64 string>",
                mimeType: 'application/pdf',
                name: 'sample.pdf' // for download
            }}
        />
    </div>
);
```

### Using with HTML file input

```javascript
import { useState } from 'react';
import FilePreviewer from '@react-league/react-file-previewer';

const PDF1_URL =
  'https://cors-anywhere.herokuapp.com/http://africau.edu/images/default/sample.pdf';

export const App = () => {
    const [file, setFile] = useState({ url: PDF1_URL });

    const onFileChange = event => {
        const fileReader = new window.FileReader();
        const file = event.target.files[0];

        fileReader.onload = fileLoad => {
            const { result } = fileLoad.target;
            setFile({ url: result });
        };

        fileReader.readAsDataURL(file);
    };

    return (
        <div>
            <h1>My App</h1>
            <input type="file" onChange={onFileChange} />
            <FilePreviewer
                file={file}
            />
        </div>
    )
};
```

### Using it as a thumbnail

This will render the first page of the file as a thumbnail. It takes the exact same props as the default export
`FilePreviewer`.

```javascript
import {FilePreviewerThumbnail} from '@react-league/react-file-previewer';

export const App = () => (
    <div>
        <h1>My App</h1>
        <FilePreviewerThumbnail
            file={{
                data: "<base64 string>",
                mimeType: 'application/pdf',
                name: 'sample.pdf' // for download
            }}
        />
        -or-
        <FilePreviewerThumbnail file={{
            url: "https://cors-anywhere.herokuapp.com/http://africau.edu/images/default/sample.pdf"}}
        />
    </div>
);
```
