What is ulid?

The ulid npm package is a library for generating Universally Unique Lexicographically Sortable Identifiers (ULIDs). ULIDs are a type of unique identifier that are lexicographically sortable, making them useful for databases and other systems where ordering by time is important.

What are ulid's main functionalities?

Generate a ULID

This feature allows you to generate a new ULID. The generated ULID is a 26-character string that is lexicographically sortable and unique.

const { ulid } = require('ulid');
const id = ulid();
console.log(id);

Monotonic ULID

This feature allows you to generate ULIDs in a monotonic manner, ensuring that they are always increasing even if generated in the same millisecond.

const { monotonicFactory } = require('ulid');
const ulid = monotonicFactory();
const id1 = ulid();
const id2 = ulid();
console.log(id1, id2);
