Single Page Application flow

[andreatosato]

Hi,
I need to create Single Page Application (angular) in microservice containered application. My solution is write using DAPR.
DAPR use opentelemetry as default trace system.
My SPA is out of DAPR application, so I need to inject client request on all services stack.

In DAPR community I found this sample for Java client.

In this sample, client create span (without tracing export) and then send information via HttpClient.
How can I replicate this?
I see this example but it use propagation with span processor:

const provider = new WebTracerProvider();
provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
provider.addSpanProcessor(new SimpleSpanProcessor(new CollectorTraceExporter()));
provider.register({ 
    contextManager: new ZoneContextManager(), 
    propagator: new B3Propagator()
});

I host angular on NGINX docker images.

Thanks a lot!

Not familiar with DAPR, but it looks like in the example you linked, they set up a span processor with Zipkin exporter and a W3C propagator. I think you should be able to change the tracer-web example to use those in a similar fashion.
