**Seeking Guidance on Implementing EffectTS, Express, and OpenTelemetry with ConsoleSpanExporter**
Need advice implementing EffectTS, Express and OpenTelemetry with ConsoleSpanExporter
Hey team. Just joined the Discord.
Not sure if it’s my misunderstanding of EffectTS or traces/spans (likely both), but a contrived implementation I have testing a call from my terminal -> server-a -> server-b looks to have a mismatch between response times and duration details that log to the screen when using the ConsoleSpanExporter (https://opentelemetry.io/docs/languages/js/exporters/#console).
Hoping to get some insight into what might be going on. I’ve published a working copy of the repo to https://github.com/okeeffed/demo-effect-ts-express, although reading Avoid the XY problem on the posting guidelines makes me think that I should be asking how others would go about it rather than my attempted implementation. So keen on that and I will add more context on my attempt in the thread.
Regardless, I’ll attach some images (if I can) of the sequence as well as a screenshot with the terminal details (also on the README).
Feel free to rip into my code if I’m misunderstanding how to apply EffectTS to these problems. Will help me learn faster.
Resources used for my own attempt
1. https://github.com/Effect-TS/effect/tree/main/packages/platform#http-client
2. https://effect.website/docs/guides/observability/telemetry/tracing
3. https://effect.website/docs/integrations/express
4. https://opentelemetry.io/docs/languages/js/exporters/#console
Desired Goal
The main goal: understanding a desirable approach to implementing telemetry with Effect.
Secondary goal: learning Express best practices with Effect.
