Developing applications defining custom types is usually inevitable. These custom types are defined to be used in other application modules. This tutorial will teach how to include these custom types in our modules. These custom types can be included in the application using theimport typeandimport...
import './a'; 上面就是preserve的编译结果,可以看到编译后的import语句不从a.js输入任何接口(包括类型),但是会引发a.js的执行,因此会保留a.js里面的副作用。 error的编译结果与preserve相同,但在编译过程中会报错,因为它要求输入类型的import语句必须写成import type的形式。原始语句改成下面的形式,就不会报错。
npm 上可用的 @types/<package> 包是从此存储库发布的。 要使用模块扩充向 Request 接口添加新属性,我们必须在本地类型声明文件中复制相同的结构。 例如,假设我们创建了一个名为 express.d.ts 的文件,如下所示,然后将其添加到 tsconfig.json 的 types 选项中: import ...

@types/jest 這些套件會新增至 devDependencies 底下的 package.json 檔案。 TypeScript 複製 "@types/jest": "^29.5.8", "jest": "^29.7.0", "jest-editor-support": "^31.1.2" 在package.json中,於 test 區段結尾新增 scripts 區段: Jest 莫查 JSON 複製 "scripts": { ... "test": ...
该泛型实现需要掌握 Distributive Conditional Types typeT=Extract<1|2,1|3>;// -> 1 Parameters。获取函数入参类型 declarefunctionf1(arg:{a:number;b:string}):void;typeT=Parameters<typeoff1>;// ↓typeT=[arg:{a:number;b:string;}];
Unexported Types– if an exported function references an unexported type, TypeScript’sd.tsemit will still declare the type locally. Copy exportfunctiondoSomething(obj: Options): void;// Not exported, but used by 'doSomething'!interfaceOptions{// ...} ...
import{assertType,expectTypeOf}from"vitest";import{mount}from"./mount";test("my types work properly", ()=>{expectTypeOf(mount).toBeFunction();expectTypeOf(mount).parameter(0).toMatchTypeOf<{name:string}>();}); This is pretty cool and having it built into a test runner is really va...
