npm install fast-b64
const bitstobase64 = require('fast-b64/bits-to-base64');
const bits = '000011110000000000010111000000000001100000000000000010000011';
const base64 = bitstobase64(bits);
// base64 is 'DwAXABgACD=='
const base64tobits = require('fast-b64/base64-to-bits');
const base64 = 'DwAXABgACD==';
const bits = base64tobits(base64);
// bits is '000011110000000000010111000000000001100000000000000010000011'
