How to use grpc-web in tauri?

[NicFTK]

I would like to use grpc-web in Tauri, but in a Tauri application, the webview can only connect to the network through its own HTTP module. Is there any way to use grpc-web in Tauri?

I had Searched on GitHub and Stack Overflow.
And tried running grpc-web directly in Tauri, but encountered errors.

As far as i am aware, grpc-web should "just work" in Tauri. There are a few issues like this one for example #9288 (macos) but that also implies that the it generally works.

Which OS / OS version are we talking about here?

Are you sure it's not a server side issue?

Thank you for your response. I spent quite a bit of time troubleshooting the issue, which made me doubt whether grpc-web could be used in Tauri. After rechecking my code, I found that it was indeed a configuration error. Now, it is running correctly in my Tauri app.
