Decode base64 encoded string

[Drakes-0]

I don't want to install another library to decode base64 encoded string, so should I use this lib in strange way like this ?
base64url.decode(base64url.fromBase64(string))

You don't need a library for that.

Buffer.from(b64string, 'base64') // decode to a Buffer
Buffer.from(b64string, 'base64').toString('utf-8') // decode to a string
