Typescript Node.js应用程序中的guid/uuid [英] guid/uuid in Typescript Node.js app

问题描述

我尝试使uuid(v 3.0.1)程序包在Node/Typescript应用程序中工作，但是我不确定应该导入什么以及如何使用它.

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.

这是index.d.ts(来自@types/uuid v 2.0.29):

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

我在这里找不到导出的类.

I cant find exported class here.

例如angular2-uuid中的index.d.ts看起来像这样:

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();
}

使用起来很明显:

let id = UUID.UUID();

所以.如何使用(导入和调用)uuid?

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

推荐答案

是的，这是我项目中的代码:

Yes, here is code from my project:

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

注意:要安装定义，必须先运行

Note: to install definitions it is required to run

npm install --save-dev @types/uuid
