Base64 encoding/decoding in pure JS on both modern Browsers and Node.js based on base64-js.
Also supports URL-safe base64
- Supports typeof
string,numberandbigint - Supports
ArrayBufferorUint8Array - Encoding/Decoding via
TextEncoder/TextDecoderunder browser andBufferunder Node.js - Building various modules
ESM,UMDandCJS
- Ability of TextEncoder and TextDecoder
- Polyfill text-encoding for Edge
- v10.4.0+ for
bigintbase64 encoding - ICU installation for base64 decoding with char encodings other then
utf-8andutf-16le

Note: text-encoder-lite parse 4-bytes UTF-8 char incorrectly,
so use text-encoding instead.
