Hey friends! I recently had the opportunity to build a POC with Vercel Functions for the startup I’m working at. I was blown away how awesome the developer experience is and how easy it was to integrate OpenTelemetry. I decided to write a tutorial with a simplified code sample on how to configure a Vercel functions for production with OpenTelemetry for distributed tracing and integration tests using trace-based testing. Everything I learned is in the article below. I hope it will be helpful and useful to the community here. Thanks!
