Base62 is a compact binary-to-text encoding that uses digits, uppercase letters, and lowercase letters.
Base62 is useful for short text identifiers because it avoids punctuation while staying more compact than hexadecimal.
Hello -> 5TP3P3v
5TP3P3v -> Hello// npm install base-x
import basex from 'base-x';
const base62 = basex('0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz');
const encoded = base62.encode(Buffer.from('Hello'));
console.log(encoded);
// Output: 5TP3P3v
const decoded = Buffer.from(base62.decode('5TP3P3v')).toString('utf8');
console.log(decoded);
// Output: Hello
