Twitter's Snowflake generator for NodeJS.
Snowflake-UUID can generate unique Id numbers at high scale with some simple guarantees.
npm install snowflake-uuid
// or
yarn add snowflake-uuid
// or
pnpm add snowflake-uuid
import { Worker } from 'snowflake-uuid';
// const { Worker } = require('snowflake-uuid');
const generator = new Worker(0, 1, {
workerIdBits: 5,
datacenterIdBits: 5,
sequenceBits: 12,
});
generator.nextId(); // 87559690812260352n
generator.nextId().toString(); // 87559690833231872
generator.getCurrentSequence(); // 0n
generator.getDatacenterId(); // 1n
generator.getLastTimestamp(); // 1630335057075n
generator.getWorkerId(); // 0n
Generated IDs are BigInt and can be easily converted into strings.
