in-browser-download

Download a Blob, a string or an ArrayBuffer as a file in the browser.

The 1.x.x versions of this package was mostly a convenience wrapper for datauri-download and base64-arraybuffer.

Starting with 2.x.x, the package does not have any dependency anymore and use newer APIs (namely Blob Urls and TextEncoder). At the time of writing, TextEncoder is not supported yet in Edge so you might want to use a polyfill or use the 1.x.x version of this package.

Installing

With npm do:

npm install in-browser-download

Examples

Text content with a text string

const download = require('in-browser-download');
 
download('some text string', 'text-file.txt');

Binary content with an ArrayBuffer

const download = require('in-browser-download');
 
const buffer = (new Uint8Array([1, 2, 3, 4, 5])).buffer;
 
download(buffer, 'binary-file.dat');
