How to generate uuid in Node.js?

@madalyn I usually use this UUID library to generate UUID in Node.js, code:

to install this library run this command:

1

npm install uuid

and then you can use it like this:

1
2
3
4

import { v4 as uuidv4 } from 'uuid';

// Output: '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d'
let id = uuidv4();

To generate a UUID (Universally Unique Identifier) in Node.js, you can make use of the uuid module. Follow the steps below to generate a UUID:

1. Install the uuid module by running the following command:

1

npm install uuid

1. In your JavaScript file, require the uuid module:

1

const { v4: uuidv4 } = require('uuid');

1. Generate a UUID using the uuidv4() function:

1
2

const uuid = uuidv4();
console.log(uuid);

The uuidv4() function generates a version 4 UUID, which is randomly generated. The generated UUID will be a string in the format ******xx-***x-4***-y***-************, where each x is a randomly generated hexadecimal digit (0-9, a-f), and y is a randomly generated hexadecimal digit from the set {8, 9, A, or B}.
