Allow overriding Tapir endpoint inputs created by Caliban's HttpInterpreter

[olisikh]

Hi,

I want to override the path prefix of Caliban's Tapir endpoints made by HttpInterpreter, but it seems there's no way to do it with existing HttpInterpreter implementation.

Ultimately I want to run a NettyZioServer providing tapir endpoints directly and control the paths my APIs go into.

Example:

val api: List[ZServerEndpoint[...]] = ???
val graphql: List[ZServerEndpoint[...]] = ???
val status: List[ZServerEndpoint[...]] = ???

NettyZioServer[R]()
  .addEndpoints(api)     // path /api
  .addEndpoints(graphql) // path /graphql (desired), but currently it's "any path" due to .in(extractFromRequest(identity))
  .addEndpoints(status)  // path /status
  .host(...)
  .port(...)
  .start()

I've originally asked this question in Caliban's Discord channel here: https://discord.com/channels/629491597070827530/633200096393166868/1227766362714275922

Pierre answered that we could implement some intermediate case class within HttpInterpreter to allow overriding endpoint inputs:

I'm happy to do this myself once I get time (probably over the weekend), I initially thought of feeding in the user's EndpointInput replacing the .in(extractFromRequest(identitiy)) to allow users to decide the rest of the inputs they want.

Please let me know if you otherwise have any ideas or suggestions.

Appreciate your time 🙏
