Discussion: How should we use service discovery in Blazor WASM?

See original GitHub issue

I was building out a sample that I wanted to contribute via PR. The sample would have a Blazor WASM frontend and a simple Web API backend.

As with the angular sample, I was forced to hard-code the ports so I could know how to call the API on the back-end. The Blazor WASM project runs client-side, so it wouldn’t have access to the server-side configuration settings unless I hosted it in an ASP.NET Core project complicating the sample.

I know hard-coding for client-side apps is the reality now, but is there any plans to ease this minor pain? I saw some issues mention generating constants use a source generator, but that didn’t seem to be in progress.

BTW: The GetServiceUri extension method works well server-side and that was a great addition.

Client-side apps are different due to being executed on the client. I think that you either have to request it from the orchestrator somehow or inject it at build time.

Ideally, there would be an API endpoint which the client-side app would request configuration from. Tye could provide that endpoint.

@robertsundstrom hit the nail on the head here; either we need to inject it at build time, which requires knowing about a publicly exposed ingress endpoint, or setup a service/api.

I’m not sure which solution is better here though.
