Blob Polyfill serves Blob.js over npm.
Blob.js implements the W3C Blob
interface in browsers that do not natively support it.
To install this library, run:
$ npm install blob-polyfill --save
CommonJS:
var Blob = require('blob-polyfill').Blob;
AMD
import { Blob } from 'blob-polyfill';
Blob.js shares the same supported browsers as FileSaver.js.
