Generate 1 to 1000 IDs per batch.
Generated values stay in your browser. This page does not send UUIDs or GUIDs to a server for generation.
Install the uuid package
The uuid package is a common JavaScript library for UUID generation. Install it when you want a package API for UUID versions and cross-environment usage.
npm install uuidGenerate UUID v4 and UUID v7
Use v4 for random UUIDs. Use v7 when you want timestamp-ordered IDs and your installed package version supports it.
import { v4 as uuidv4, v7 as uuidv7 } from "uuid";
console.log(uuidv4());
console.log(uuidv7());Generate multiple UUIDs
Generate multiple UUIDs by mapping over the count you need. Keep batches bounded in scripts and tests.
Common npm uuid mistakes
Check the package version before using newer APIs such as v7. Avoid mixing CommonJS and ESM syntax in the same file unless your build setup supports it.
