README
image-type 
Detect the image type of a Buffer/Uint8Array
See the file-type module for more file types and a CLI.
Install
$ npm install image-type
Usage
Node.js
const readChunk = require('read-chunk');
const imageType = require('image-type');
const buffer = readChunk.sync('unicorn.png', 0, 12);
imageType(buffer);
//=> {ext: 'png', mime: 'image/png'}
Or from a remote location:
const https = require('https');
const imageType = require('image-type');
const url = 'https://upload.wikimedia.org/wikipedia/en/a/a9/Example.jpg';
https.get(url, response => {
response.on('readable', () => {
const chunk = response.read(imageType.minimumBytes);
response.destroy();
console.log(imageType(chunk));
//=> {ext: 'jpg', mime: 'image/jpeg'}
});
});
Browser
const xhr = new XMLHttpRequest();
xhr.open('GET', 'unicorn.png');
xhr.responseType = 'arraybuffer';
xhr.onload = () => {
imageType(new Uint8Array(this.response));
//=> {ext: 'png', mime: 'image/png'}
};
xhr.send();
API

Returns an Object with:

It only needs the first .minimumBytes bytes.
imageType.minimumBytes
Type: number
The minimum amount of bytes needed to detect a file type. Currently, it's 4100 bytes, but it can change, so don't hardcode it.
