blob-to-buffer

Convert a Blob to a Buffer.

Say you're using the 'buffer' module on npm, or browserify and you're working with lots of binary data.

Unfortunately, sometimes the browser or someone else's API gives you a Blob. Silly browser. How do you convert it to a Buffer?

Something with a goofy FileReader thingy... Time to Google for it yet again... There must be a better way!

There is! Simply use this module!

Works in the browser. This module is used by WebTorrent!

install

npm install blob-to-buffer

usage

var toBuffer = require('blob-to-buffer')

// Get a Blob somehow...
var blob = new Blob([ new Uint8Array([1, 2, 3]) ], { type: 'application/octet-binary' })

toBuffer(blob, function (err, buffer) {
  if (err) throw err

  buffer[0] // => 1
  buffer.readUInt8(1) // => 2
})
