module-class.d.ts.md

示例，当你想要处理如下的 JavaScriptr 的代码时：

const Greeter = require('super-greeter');

const greeter = new Greeter();
greeter.greet();

能够同时处理UMD导入和模块导入：

// Type definitions for [~THE LIBRARY NAME~] [~OPTIONAL VERSION NUMBER~]
// Project: [~THE PROJECT NAME~]
// Definitions by: [~YOUR NAME~] <[~A URL FOR YOU~]>

/*~ This is the module template file for class modules.
 *~ You should rename it to index.d.ts and place it in a folder with the same name as the module.
 *~ For example, if you were writing a file for "super-greeter", this
 *~ file should be 'super-greeter/index.d.ts'
 */

// Note that ES6 modules cannot directly export class objects.
// This file should be imported using the CommonJS-style:
//   import x = require('[~THE MODULE~]');
//
// Alternatively, if --allowSyntheticDefaultImports or
// --esModuleInterop is turned on, this file can also be
// imported as a default import:
//   import x from '[~THE MODULE~]';
//
// Refer to the TypeScript documentation at
// https://www.typescriptlang.org/docs/handbook/modules.html#export--and-import--require
// to understand common workarounds for this limitation of ES6 modules.

/*~ If this module is a UMD module that exposes a global variable 'myClassLib' when
 *~ loaded outside a module loader environment, declare that global here.
 *~ Otherwise, delete this declaration.
 */
export as namespace myClassLib;

/*~ This declaration specifies that the class constructor function
 *~ is the exported object from the file
 */
export = MyClass;

/*~ Write your module's methods and properties in this class */
declare class MyClass {
    constructor(customGreeting?: string);

    greet: void;

    myMethod(opts: MyClass.MyClassMethodOptions): number;
}

/*~ If you want to expose types from your module as well, you can
 *~ place them in this block.
 *~
 *~ Note that if you decide to include this namespace, the module can be
 *~ incorrectly imported as a namespace object, unless
 *~ --esModuleInterop is turned on:
 *~   import * as x from '[~THE MODULE~]'; // WRONG! DO NOT DO THIS!
 */
declare namespace MyClass {
    export interface MyClassMethodOptions {
        width?: number;
        height?: number;
    }
