GRPC exporter for web clients

[Ancient-Dragon]

NB: Before opening a feature request against this repo, consider whether the feature should/could be implemented in the other OpenTelemetry client libraries. If so, please open an issue on opentelemetry-specification first.

Is your feature request related to a problem? Please describe.

The problem I'm facing is that @opentelemetry/exporter-trace-otlp-grpc states that it for web, but when I have tried to make it work it just throws a bunch of errors in my frontend client. After doing some research it appears as though it shouldn't suggest it is for web because it uses: @grpc/grpc-js which is for node-js and rather it should be using grpc-web.

Describe the solution you'd like

Ideally I'd like to be able to have my traces sent to my collector using a GRPC exporter in my frontend client.

Describe alternatives you've considered

Alternatives are currently to use https.

Additional context

None that I know of.

Hmm sorry for the incorrect docs. The OTLP/HTTP exporter works in the web and exports using JSON over HTTP.

[Ancient-Dragon]

No worries, that's why I made this a feature request to see if a grpc-web exporter could be made, if not please feel free to close this.

If i'm not mistaken there is no way of using the official grpc client in the browser ? There are alternatives (https://github.com/improbable-eng/grpc-web or https://github.com/grpc/grpc-web) but this would requires making new exporters i believe

[Ancient-Dragon]

Yes that is the ask of this feature request, to make a new exporter library using the grpc-web dependency.

Do we have any way to use grpc web trace exporter now?

[pksorensen]

This would make sense to have, as there are collectors only supporting grpc. https://github.com/dotnet/aspire/issues/3688
