Usage

import URLSafeBase64 from "https://code4fukui.github.io/urlsafe-base64/index.js";

.encode(buffer)

Encodes a buffer as a URL Safe Base64 string. This function encodes to the RFC 4648 Spec where '+' is encoded as '-' and '/' is encoded as '_'. The padding character '=' is removed.

let randomURLSafeBase64;
crypto.randomBytes(32, function(err, buf) {
  if (err) {
    throw err;
    return;
  };
  randomURLSafeBase64 = URLSafeBase64.encode(buf);
});

.decode(string)

Decodes a URL Safe Base64 string as a buffer.

const someURLSafeBase64 = '';
URLSafeBase64.decode(someURLSafeBase64); // returns a buffer

.validate(string)

Validates a string if it is URL Safe Base64 encoded.

const validURLSafeBase64 = '';
URLSafeBase64.validate(validURLSafeBase64); // returns true

const invalidURLSafeBase64 = '/+=='
URLSafeBase64.validate(invalidURLSafeBase64); // returns false
