i dont have one

Describe the Bug

I recently upgraded wrangler and friends to latest versions and noticed a new type in worker-configuration.d.ts I have a fairly complex monorepo with types defined and imported all over the place, but this line seems to break my typechecking

interface GlobalProps {
 	mainModule: typeof import("./src/index");
}

commenting it out fixes my typechecking

Please provide any relevant error logs

Hi. We haven't been able to reproduce this issue. Could you share a minimal reproduction and the TypeScript error messages? This will help us debug this.

Thanks!

Hi. I created a repro repo here

To repro run: pnpm i && pnpm run typecheck The typecheck will fail.

Now, comment out the interface defined in the worker-config file ( /packages/types/src/worker-configuration.d.ts) Rerun typecheck and it's all green

pnpm run typecheck

Could you please paste the exact error message in the thread, so not everyone has to run the repro to see it?

Also can you share exactly the command you run to generate the worker-configuration.d.ts, including what directory you run it from?

I haven't run the repro, but I notice it looks like you store your worker-configuration.d.ts in a different package from the worker main module, and I'm guessing that's the problem. The generated GlobalProps looks like:

declare namespace Cloudflare {
  interface GlobalProps {
    mainModule: typeof import("../../../apps/web/workers/app");
  }

But this is trying to import a file from some other package. I guess that's what doesn't work (but still, please post the info to confirm).

I am not really sure if worker-configuration.d.ts is intended to be possible to put in a separate package from the worker itself. @penalosa what do you think?

[shmuli9]

You are correct that the worker types are being generated into a different package. This is so I can share the types more easily with other packages (I simplified them out for the repro though)

I am not surprised that this isn';t an expected use case, but it is handy. An opt out of the GlobalProps import would be a workable solution, similar to how I opt out of strict vars on the command line

The command to generate the cf types is in the package.json of the apps/web, it is:

"cf-typegen": "wrangler types ../../packages/types/src/worker-configuration.d.ts --strict-vars false",

The type error, when running pnpm run typecheck in the root of the repo (this uses turbo to run the typecheck command in each of the packages in the repo, so it runs in apps/web and also packages/types):

 ~/code/bug-repro > pnpm run typecheck                    

  > @bug-repro/root@ typecheck /home/shmuli/code/bug-repro
