Typescript中的 module.exports

发布于11月01日

有人知道怎么做模块吗.出口？

我try 了一些不同的方法

export class Greeter {}

将编译为

exports.Greeter = Greeter;

但我真正想要的是:

exports = Greeter;

所以我可以这样使用它:

import { Greeter } from "greeter";

const greeter = new Greeter();

而不是

import { Greeter } from "greeter";

const greeter = new Greeter.Greeter();

Typescript可以这样做吗？

推荐答案

可以像这样导出TypeScript中的单个类:

class Person {

  private firstName: string;
  private lastName: string;

  constructor(firstName: string, lastName: string) {
    this.firstName = firstName;
    this.lastName = lastName;
  }

  public getFullName() {
    return `${this.firstName} ${this.lastName}`;
  }
}

export = Person;

下面是如何使用它:

var Person = require('./dist/commonjs/Person.js');

var homer = new Person('Homer', 'Simpson');
var name = homer.getFullName();

console.log(name); // Homer Simpson

以下是我的tsconfig.json(我使用的是TypeScript v2.0.3):

{
  "compilerOptions": {
    "module": "commonjs",
    "moduleResolution": "node",
    "outDir": "dist/commonjs",
    "rootDir": "src/ts",
    "target": "es5"
  },
  "exclude": [
    "dist",
    "node_modules"
  ]
}
