TypeScript:为同一项目中的不同文件声明不同的库/引用
我有一个用TypeScript编写的项目。我同时使用dom和Workers，所以在一些文件中需要webworker.d.ts库，在其他文件中需要dom.d.ts。
我已经尝试过在tsconfig.json中的lib选项中添加"webworker“，但这两个选项是不兼容的。
我试过的另一件事是补充：
/// <reference no-default-lib="true"/>
/// <reference lib="esnext" />
/// <reference lib="webworker" />在我的服务工作者文件的顶部，但是"webworker“应用于每个文件，而不仅仅是包含引用的文件。
如何在同一个项目中同时拥有需要引用dom的文件和需要引用webworker的文件？
这是我的配置：
// tsconfig.json
{
"compilerOptions": {
"target": "esnext",
"module": "esnext",
"strict": true,
"jsx": "preserve",
"importHelpers": true,
"noEmitHelpers": false,
"moduleResolution": "node",
"experimentalDecorators": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true,
"sourceMap": true,
"baseUrl": ".",
"types": ["webpack-env"],
"paths": {
"@/*": ["src/*"]
},
"lib": ["esnext", "dom", "dom.iterable", "scripthost"]
},
"include": [
"src/**/*.ts",
"src/**/*.tsx",
"src/**/*.vue",
"tests/**/*.ts",
"tests/**/*.tsx"
],
"exclude": ["node_modules"]
}

关于vue，请参见微软/打字本/问题/20595，它声明：
We have found that what is meaningful in the global scope of a web worker is significantly more narrow than we find out of the DOM. So we tend to author with "lib": [ "dom" ] and then just declare the handful of APIs we require to make a web worker work, or we obtain a reference to the global object, treat it as any, and pick off certain properties from the global scope and type them at the point where we pick them off.
试着像：
const ctx: Worker = self as any;
ctx.postMessage();或者:遵循链接20595配方，这将需要排版到某些webworker部件，或者为您需要/使用的组件制作类型文件。
使用：
const globalObject: any = (function (): any {
if (typeof global !== 'undefined') {
// global spec defines a reference to the global object called 'global'
// https://github.com/tc39/proposal-global
// `global` is also defined in NodeJS
return global;
}
else if (typeof window !== 'undefined') {
// window is defined in browsers
return window;
}
else if (typeof self !== 'undefined') {
// self is defined in WebWorkers
return self;
}
})();然后引用，例如：
import globalObject from 'globalObject'
globalObject.postMessage({});https://stackoverflow.com/questions/54188827
