我熟悉TypeScript中的export
关键字,以及使用TypeScript从Node模块导出内容的两种规范方法(当然,也可以使用TypeScript模块,但它们甚至更远我正在寻找):
export class ClassName { }
和一系列
export function functionName () { }
但是,我通常编写模块的方式是:以后将它们作为可实例化的闭包导入:
var ClassName = function () { };
ClassName.prototype.functionName = function () { };
module.exports = ClassName;
我是否可以使用TypeScript导出语法执行此操作?
答案 0 :(得分:18)
你可以在TypeScript 0.9.0中完成这些工作:
class ClassName {
functionName () { }
}
export = ClassName;

以下是我使用TypeScript导出CommonJS(Node.js)模块的方法:
<强>的src / TS /用户/ User.ts 强>
export default class User {
constructor(private name: string = 'John Doe',
private age: number = 99) {
}
}
<强>的src / TS / index.ts 强>
import User from "./user/User";
export = {
user: {
User: User,
}
}
<强> tsconfig.json 强>

dist / commonjs / index.js(编译模块入口点)

const User_1 = require("./user/User");
module.exports = {
user: {
User: User_1.default,
}
};
//# sourceMappingURL=index.js.map
dist / commonjs / user / User.js(已编译用户类)
"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
class User {
constructor(name = 'John Doe', age = 72) {
this.name = name;
this.age = age;
}
}
exports.default = User;
//# sourceMappingURL=User.js.map
测试代码(test.js)
const MyModule = require('./dist/commonjs/index');
const homer = new MyModule.user.User('Homer Simpson', 61);
console.log(`${homer.name} is ${homer.age} years old.`); // "Homer Simpson is 61 years old."
