How can I check if a global provider is registered

[bahlo]

Calling trace.getTracerProvider always returns a value, is there a way to check if it's been set?

There is currently no official way to do this, but you can check the returned tracer to see if it is the class you expect or you could inspect the global maintained by the API. What usecase are you trying to solve? Adding functionality like this to the API may be possible if there is good reason for it.

Thanks for getting back so quickly! 💯 We're working on a specific library that sets up everything for you (including exporter, provider, etc.) and we want to register the provider if it's not been set up yet.

how does that differ from https://github.com/open-telemetry/opentelemetry-js/tree/main/experimental/packages/opentelemetry-sdk-node? Is there a chance we can consolidate effort here?

if you try to register a TracerProvider and there is already one registered it will fail and return value of setGlobalTracerProvider is false.
