Is it possible to host theia-front end and back-end on two different machines?

[kumbham]

I read that theia has separate processes for backend and frontend. I'm curious if we could host these processes in two different machines and open a WebSocket connection for JSONRpc communication? If yes, could you please share a sample application with this configuration?

It seems like these processes can also communicate via Rest APIs. Could you please share a code snippet for this configuration as well.

Thanks!

Yes. The frontend process is the web-app associated with the browser's tab. The backend process can live on a separate machine that you access when you load the frontend application.

Sure. You can try Theia in Gitpod: https://gitpod.io/#https://github.com/eclipse-theia/theia
The web app runs in your browser, and the Theia backend is running one of the nodes provided by Gitpod. They're on two different machines.

It seems like these processes can also communicate via Rest APIs. Could you please share a code snippet for this configuration as well.

Yes, you can do this as well. For example, the file download functionality is exposed as a RESTful API using express. See an example here.
