示例,当你想要处理如下的 JavaScriptr 的代码时:
ts
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:
ts
// 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;
}
}
