@waiting/base64/dist/lib/config.js

Base64 encoding/decoding in pure JS on both modern Browsers and Node.js. Also supports URL-safe base64

export const baseChars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/'

export const revLookup = []
for (let i = 0, len = baseChars.length; i < len; ++i) {
    lookup[i] = baseChars[i]
    revLookup[baseChars.charCodeAt(i)] = i
}
// Support decoding URL-safe base64 strings, as Node.js does.
// See: https://en.wikipedia.org/wiki/Base64#URL_applications
revLookup['-'.charCodeAt(0)] = 62
revLookup['_'.charCodeAt(0)] = 63
