# file-type [](https://travis-ci.org/sindresorhus/file-type)
|
||||
|
||||
> Detect the file type of a Buffer/Uint8Array
|
||||
|
||||
The file type is detected by checking the [magic number](http://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files) of the buffer.
|
||||
|
||||
|
||||
## Install
|
||||
|
||||
```
|
||||
$ npm install --save file-type
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
##### Node.js
|
||||
|
||||
```js
|
||||
const readChunk = require('read-chunk');
|
||||
const fileType = require('file-type');
|
||||
const buffer = readChunk.sync('unicorn.png', 0, 4100);
|
||||
|
||||
fileType(buffer);
|
||||
//=> {ext: 'png', mime: 'image/png'}
|
||||
```
|
||||
|
||||
Or from a remote location:
|
||||
|
||||
```js
|
||||
const http = require('http');
|
||||
const fileType = require('file-type');
|
||||
const url = 'http://assets-cdn.github.com/images/spinners/octocat-spinner-32.gif';
|
||||
|
||||
http.get(url, res => {
|
||||
res.once('data', chunk => {
|
||||
res.destroy();
|
||||
console.log(fileType(chunk));
|
||||
//=> {ext: 'gif', mime: 'image/gif'}
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
##### Browser
|
||||
|
||||
```js
|
||||
const xhr = new XMLHttpRequest();
|
||||
xhr.open('GET', 'unicorn.png');
|
||||
xhr.responseType = 'arraybuffer';
|
||||
|
||||
xhr.onload = () => {
|
||||
fileType(new Uint8Array(this.response));
|
||||
//=> {ext: 'png', mime: 'image/png'}
|
||||
};
|
||||
|
||||
xhr.send();
|
||||
```
|
||||
|
||||
|
||||
## API
|
||||
|
||||
### fileType(input)
|
||||
|
||||
Returns an `Object` with:
|
||||
|
||||
- `ext` - One of the [supported file types](#supported-file-types)
|
||||
- `mime` - The [MIME type](http://en.wikipedia.org/wiki/Internet_media_type)
|
||||
|
||||
Or `null` when no match.
|
||||
|
||||
#### input
|
||||
|
||||
Type: `Buffer` `Uint8Array`
|
||||
|
||||
It only needs the first 4100 bytes.
|
||||
