Usage
Browser
Include this script tag in your <head>:
<script src="https://cdn.jsdelivr.net/npm/base91-js@1.0.8/dist/base91.min.js"></script>Node
const {
encode,
decode,
create
} = require("base91-js");
/*
or
const base91 = require("base91-js");
*/To encode:
const textToEncode = "Hello 👋. 这是一些中文文本. А вот и русский текст."
const encoded = base91.encode(textToEncode);
console.log(encoded);To decode:
const textToDecode = ">OwJh>&\"zkMICB;`TkMK)9C+cLmp_Zv=k2k`F[fVYUifCB2k/t7fj/^xtLg4FE+k4YER7tKFf#+4FE9gIY)F`#n;`od56[C"
const decoded = base91.decode(textToDecode);
console.log(decoded);Chunked encoding
Note: Chunked encoding uses typed arrays, not strings, so you'll need to use a TextEncoder if you want to use strings.
const encoder = new TextEncoder();
const base91_encoder = base91.create();
const view1 = encoder.encode("Hello, ");
const view2 = encoder.encode("world");
base91_encoder.update(view1);
base91_encoder.update(view2);
const result = base91_encoder.finalize();Credits
