Generating Globally Unique IDs in Distributed Systems

#javascript #webdev #programming

In today's distributed systems, one of the key challenges is generating unique identifiers (IDs) in highly concurrent and distributed environments. Snowflake, a tool commonly used in distributed systems to generate globally unique IDs with a timestamp component. Discover why Snowflake IDs are a valuable asset for your project.

This library is only inspired by the existing Snowflake project, but is written by me.
So if you find an error, let me know.

Also added a promise to ensure that the ID is never repeated.

Generating Unique IDs in Any Context

Snowflake IDs ensure uniqueness in distributed and multi-threaded environments.

You can also decode any ID to object, here is a example:

import { Snowflake, decodeSnowflake } from "@skorotkiewicz/snowflake-id";

(async () => {
  const machineId = 1; // machine ID (0-1023)
  const snowflake = new Snowflake(machineId);

  const id1 = await snowflake.generate();
  console.log("encodeID", id1);
  // output: 7160521316708126720

  const decoded = decodeSnowflake(id1);
  console.log("decodeID", decoded);
  // output: { timestamp: '2024-02-06T05:12:47.730Z', machineId: '1', sequence: '0' }
})();
