blob-stream

A Node-style writable stream for HTML5 Blobs, mostly useful in Browserify. Allows you to take the output of any Node stream, and turn it into a Blob or Blob URL for opening in the browser, uploading to a server, etc.

If you don't want to use Browserify, you can also download a prebuilt version of the library.

Example

var blobStream = require('blob-stream');
 
someStream
  .pipe(blobStream())
  .on('finish', function() {
    // get a blob
    var blob = this.toBlob();
    
    // or get a blob URL
    var url = this.toBlobURL();
    window.open(url);
  });
