Use in Node.js

const dagCBOR = require('ipld-dag-cbor')

Use in a browser with browserify, webpack or any other bundler

The code published to npm that gets loaded on require is in fact a ES5 transpiled version with the right shims added. This means that you can require it and use with your favourite bundler without having to adjust asset management process.

var dagCBOR = require('ipld-dag-cbor')

Use in a browser Using a script tag

const dagCBOR = require('ipld-dag-cbor')

const file = {
  name: 'hello.txt',
