guid/uuid in Typescript Node.js app

I try to make a uuid (v 3.0.1) package work in Node/Typescript app, but I'm not sure what should I import and how to use it.

This is index.d.ts (from @types/uuid v 2.0.29):

declare namespace uuid { interface V1Options { node?: number[]; clockseq?: number; msecs?: number | Date; nsecs?: number; } type V4Options = { random: number[] } | { rng: () => number[]; } interface UuidStatic { (options?: V4Options): string; (options: V4Options | null, buffer: number[], offset?: number): number[]; (options: V4Options | null, buffer: Buffer, offset?: number): Buffer; v1(options?: V1Options): string; v1(options: V1Options | null, buffer: number[], offset?: number): number[]; v1(options: V1Options | null, buffer: Buffer, offset?: number): Buffer; v4: UuidStatic; parse(id: string): number[]; parse(id: string, buffer: number[], offset?: number): number[]; parse(id: string, buffer: Buffer, offset?: number): Buffer; unparse(buffer: number[] | Buffer, offset?: number): string; } } declare const uuid: uuid.UuidStatic export = uuid 

I cant find exported class here.

For example index.d.ts from angular2-uuid looks like that:

export declare class UUID { constructor(); static UUID(): string; private static pad4(num); private static random4(); } 

And it's quite obvious to use:

let id = UUID.UUID(); 

So. How to use (import and call) uuid?

Yes, here is code from my project:

import { v4 as uuid } from 'uuid'; const id: string = uuid(); 

Note: to install definitions it is required to run

npm install --save-dev @types/uuid 

Per the tests:

import uuid = require('uuid'); let uuidv4: string = uuid.v4(); 

import * as uuid from "uuid"; const id: string = uuid.v4(); 

This also works for me:

import uuidv4 from 'uuid/v4' this.projectId = uuidv4() 

I used uuid for my project in the following order

Must be installed

npm i --save-dev @types/uuid npm install uuid 

Using the uuid package

import { v4 as uuidv4 } from 'uuid'; let myuuid = uuidv4(); console.log('Your UUID is: 'myuuid);
