README

base64-js

base64-js does basic base64 encoding/decoding in pure JS.

build status

Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.

Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.

install

With npm do:

npm install @guld/base64-js and import base64js from '../base64-js/base64.js'

For use in web browsers do:

<script src="base64js.min.js"></script>

methods

base64js has three exposed functions, byteLength, toByteArray and fromByteArray, which both take a single argument.

  • byteLength - Takes a base64 string and returns length of byte array
  • toByteArray - Takes a base64 string and returns a byte array
  • fromByteArray - Takes a byte array and returns a base64 string
