Fast, lexicographic base62 encode and decode

High-performance base62 encoder/decoder for JavaScript and Node.js. Supports Number and BigInt inputs, optimized for both time and space complexity.

Generate random token using base62 which is alphanumeric with uppercase and lowercase.

JavaScript port of base62.io

string-base62

Generate base62-encoded unique identifiers

Encode and decode strings to base62

Generate consistent, unique shadow IDs based on input data. Combines SHA256 hashing, base62 encoding, and timestamp extraction for deterministic ID generation.

Generate base62 pseudo-random sequence IDs

Fast Base62 encoder and decoder

Generates a uuid v4 that is base62 encoded which makes the result compact, and url friendly. Example: `card_3xs3cYSzXKNI5vhHA203qK`

A compact, fast, timestamp-based unique ID generator using custom epoch and Base62 encoding.
