UUIDv4

Library for generating UUID (universally unique identifier) version 4 strings.

The library will use window.crypto to generate random numbers if it detects that it is available, else it will fallback to use Math.random.

Usage

let uuid: string = UUIDv4.generateUUID();

Sample Angular Karma test

import { TestBed, inject } from '@angular/core/testing';
import { UUIDv4 } from 'uuid-version4';

describe('sample test', () => {
  beforeEach(() => {
    TestBed.configureTestingModule({
      imports: []
    });
  });

  it('it should generate UUID version 4 string', inject([], () => {
    let uuid: string = UUIDv4.generateUUID();
    expect(uuid).toBeTruthy();
    expect(uuid.length).toBe(36);
    expect(uuid[14]).toBe('4');
  }));
});
