error TS2304: Cannot find name 'DedicatedWorkerGlobalScope'

[laurentpellegrino]

Using version 7.0.4 with this tsconfig:

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "declaration": true,
    "esModuleInterop": true,
    "module": "commonjs",
    "noImplicitAny": false,
    "outDir": "dist/",
    "rootDir": "src",
    "strict": true,
    "target": "es2018",
  }
}

I am getting:

tsc --emitDeclarationOnly

node_modules/penpal/dist/penpal.d.ts:193:22 - error TS2304: Cannot find name 'DedicatedWorkerGlobalScope'.

193 worker: Worker | DedicatedWorkerGlobalScope;

Adding to my tsconfig the following under compilerOptions:

    "lib": ["es2018", "dom", "webworker"]

the DedicatedWorkerGlobalScope definition is found but then I get a lot type errors with TypeScript libs:

Checking the Penpal tsconfig file, I see "skipLibCheck": true, is used. Is that voluntary?

Another solution seems to create a global.d.ts and put a dummy definition:

interface DedicatedWorkerGlobalScope extends Worker {}

However, is there no better solution than making such a definition or skipping lib types?

Hey, thanks for reporting this. I was not aware of it. Yes, Penpal's "skipLibCheck": true is intentional as I only want to focus on checking the correctness of Penpal's types and not checking types of Penpal's dependencies.

Honestly, I'm not sure what the right solution is at the moment. I need to get some time to research it and test out some options. The solutions you've come up with (making a defintions or skipping lib types) are probably your best bet at the moment. Sorry I don't have a better solution for you yet.

Hey @mike-north, if you happen to be available to look at this, I'd be curious to know how you think this should be solved.
