Tapir Tutorial - part 7: Integration with cats-effect & http4s | Adam Warski SoftwareMill

Tapir: rapid development of self-documenting HTTP APIs

We've seen how to use Tapir in combination with direct-style, but one of Tapir's main strengths is that it integrates with virtually every Scala stack out there. This means, first and foremost, cats-effect for describing side-effecting computations, and http4s as an HTTP server. We'll include, of course, generating OpenAPI docs!

[HelloForeignWorld]

An idea for another video: Can you show how to extend this application to have some dependency injection / context?

I understand this will not be “Tapir only” video, but it will help people bridge the gap between theoretical use of Tapir and a real world use of it
