In light of #16575, this PR adds an e2e test app for running an express app via
tsx
instead of transpiling it and running it with node directly. I basically just copied the app and tests from ournode-express
e2e app, so it also contains tests for TRPC and MCP stuff. If reviewers prefer, I can remove the additional stuff but I think it actually makes sense to test a "loaded" express app with additional instrumentation.Importantly, I had to
--import
the instrument file because TSX seems to internally transpile to ESM by default.
