UUID V4 NPM
This snippet provides a quick, efficient way to generate UUIDs using the npm UUID v4 module.
const uuidv4 = require('uuid/v4');
let id = uuidv4();
console.log(id);The 'uuid' module of npm is used in this snippet. The version 4 ('v4') method is used here, generating random, unique identifiers - UUIDs.
This code snippet first requires the 'uuid/v4' module. Once it is imported, you can use its method 'v4' to generate a new UUID and store it in the 'id' variable.
Finally, we print the generated id to the console using console.log. Every time you run this code, a unique UUID will be printed.
