guid/uuid in Typescript Node.js app
node.jsTypescriptUuidGuidnode.js Problem Overview
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
?
node.js Solutions
Solution 1 - node.js
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
Solution 2 - node.js
Per the tests:
import uuid = require('uuid');
let uuidv4: string = uuid.v4();
Solution 3 - node.js
import * as uuid from "uuid";
const id: string = uuid.v4();
Solution 4 - node.js
This also works for me:
import uuidv4 from 'uuid/v4'
this.projectId = uuidv4()
Solution 5 - node.js
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);
