guid/uuid in Typescript Node.js app
提问by tBlabs
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.
我尝试uuid在 Node/Typescript 应用程序中制作一个(v 3.0.1) 包，但我不确定应该导入什么以及如何使用它。
This is index.d.ts(from @types/uuidv 2.0.29):
这是index.d.ts（来自@types/uuidv 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.
我在这里找不到导出的类。
For example index.d.tsfrom angular2-uuidlooks like that:
例如index.d.ts从angular2-uuid看起来像这样：
export declare class UUID {
constructor();
static UUID(): string;
private static pad4(num);
private static random4();
}
And it's quite obvious to use:
使用起来很明显：
let id = UUID.UUID();
So. How to use (import and call) uuid?
所以。如何使用（导入和调用）uuid？

Yes, here is code from my project:
是的，这是我项目中的代码：
import { v4 as uuid } from 'uuid';
const id: string = uuid();
Note: to install definitions it is required to run
注意：要安装定义，需要运行
npm install --save-dev @types/uuid

import * as uuid from "uuid";
const id: string = uuid.v4();
回答by GaryO
This also works for me:
这也适用于我：
import uuidv4 from 'uuid/v4'
this.projectId = uuidv4()
回答by Joe
Per the tests:
根据测试：
import uuid = require('uuid');
let uuidv4: string = uuid.v4();
