I’m trying to create a Typescript project that supports web workers.

First I create a baseline that will compile typescript code like this.

mkdir ts
cd ts
npm init -y
npm i -D typescript
npm i -D @types/mocha

Add tsconfig.json.

{
  "compilerOptions": {
    "target": "es2021",
    "module": "es2020",
    "lib": ["es2021", "DOM", "DOM.Iterable"],
    "declaration": true,
    "declarationMap": true,
    "sourceMap": true,
    "inlineSources": true,
    "outDir": "./build",
    "rootDir": "./src",
    "strict": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "noImplicitAny": true,
    "noImplicitThis": true,
    "moduleResolution": "node",
    "allowSyntheticDefaultImports": true,
    "experimentalDecorators": true,
    "forceConsistentCasingInFileNames": true,
    "noImplicitOverride": true,
    "types": ["mocha"]
  },
  "include": ["src/**/*.ts"],
  "exclude": []
}

Add some typescript (src/hello.component.ts).

/**
 *  @category WebComponent
 *
 * Hello World Web Component
 * that renders a greeting.
 */
export class HelloWorldComponent extends HTMLElement {
    static get observedAttributes() {
      return ['name'];
    }
  
    /**
     * The name to greet
     * @defaultValue World
     */
    name: string | null = 'World';
    something!: string;
    /**
     * Initializes the name property to `World`.
     */
    constructor() {
      super();
      //    this.name = 'World';
    }
  
    /**
     * Sets the component inner
     * html to the greeting.
     */
    connectedCallback() {
      this.textContent = `Hello ${this.name}!`;
    }
  
    //========================================
    // attribute change callback
    //========================================
    attributeChangedCallback(
      property: keyof HelloWorldComponent,
      oldValue: string | null,
      newValue: string | null
    ) {
      if (oldValue === newValue) return;
      switch (property) {
        case 'name':
          this.name = newValue;
          break;
        default:
          throw new Error(`Unhandled attribute: ${property}`);
      }
    }
  }
  customElements.define('hello-world', HelloWorldComponent);

And run tsc.

This compiles fine.

And the only step left to add web worker support is to add it to the lib compiler option like this.

"lib": ["es2021", "DOM", "DOM.Iterable", "WebWorker"],

And rerun tsc. However now it generates creates all these errors. Any ideas?
