Web Worker example

[dakom]

Would be helpful to have a web-worker example... I had lots of trouble getting that to load

Would you mind sending a PR? What were your troubles?

[dakom]

Sure - I'm happy to fork/adapt to make a web-worker example.

Though when I tried with this repo, just as-is, I got:

error[E0277]: the trait bound `&mut syn::Field: quote::ToTokens` is not satisfied

@dakom can you check this issue https://github.com/rustwasm/wasm-bindgen/issues/799 I think it is the same. Run cargo update

[dakom]

Yep, that fixed that error :)

Here you go - I put the changes in its own branch on the fork: https://github.com/dakom/rust-webpack-template/tree/worker-example

@dakom awesome, let me have a look 👍

Thanks! Related discussion fyi: https://github.com/webpack-contrib/worker-loader/issues/144

I'm running into the same error when trying to load a wasm-bindgen crate inside a web worker using webpack:

TypeError: Cannot read property '../client-wasm-worker/pkg/client_wasm_worker_bg.wasm' of undefined

This is only after using this workaround for a window is not defined error.

Any help would be greatly appreciated.
