Is there any example of InstrumentationNodeModuleFile for InstrumentationBase ?

[Nighttraveler]

Hi guys,
I'm asking this because we would like to patch some files in our project so in this way we leave the files as it is (no otel code there) and use opentelemetry-instrumentation whenever is possible.

This is the only reference I found related to the files

• Do we have to export the types for each of the class and functions?
• It is possible to link this files to a dependency instrumentation?
  For example we patch some functions of the apollo client dependency and we configure an apolloFetch object that apolloLink uses in some hooks. useQuery at some point arrives at our customFetch we would like that the span created in the useQuery patch wraps one created in the custom fetch file instrumentation and then HTTPInstrumentation one.

* useQuery Span
* * CustomFetch Span
* * * HTTPInstrumentation Span

• Will be possible to nest this spans?

Thanks in advance!
