typescript如何扩展window,添加自定义属性？

Question

tsconfig.json

{
 "compilerOptions": {
 "target": "ES3",
 "module": "ESNext",
 "strict": true,
 "jsx": "react",
 "allowJs": true,
 "importHelpers": true,
 "moduleResolution": "node",
 "skipLibCheck": true,
 "esModuleInterop": true,
 "allowSyntheticDefaultImports": true,
 "sourceMap": true,
 "experimentalDecorators": true,
 "baseUrl": "./",
 "lib": [
 "esnext",
 "dom",
 "dom.iterable",
 "scripthost"
 ]
 }, 
 "include": [
 "src/*/**"
 ]
}

src/test.ts

const a = window.client.a()

src/type.d.ts

export {}
interface Client{
 a: ()=>string
}
declare global {
 interface Window { client: Client; }
}

既然发现了Client的定义，为啥又说找不到

Answer 1

或许 .d.ts 没引入？你试着把 declare 直接写进 .ts，如果能行就是没引入
