HMR shows an error in Web Worker

[PeterPanZH]

Uncaught ReferenceError: window is not defined

https://github.com/snowpackjs/snowpack/blob/626b8fa8c2109f6903ca4ea3731d4f6ae6eac00a/snowpack/assets/hmr-client.js#L200

There is no window object in WorkerGlobalScope. Should we support webworker here?

Hi @PeterPanZH some more info about where you encountered this error would help me figure out how to debug it. Thanks!

Using import.meta in a worker will trigger this problem.

Minimal reproduction:

Ah, interesting. This messes with our "just load ESM in the worker" story for web workers during development. We may need that bundling step after all.

I ran into this too, it would be great if there was a way to disable HMR for certain mounts? Is there another workaround?

Same here :(

fixed by #1896
upgrade to [email protected] should solve the problem lol
