    Project mention: A question about Http4s new major version | /r/scala | 2023-04-25

    Those benchmarks are using a snapshot version of cats-effect. I don't know where that one comes from, but previously they were using a snapshot from https://github.com/typelevel/cats-effect/pull/3332 which had some issues (3.5-6581dc4, 70% performance degradation), which have since been resolved (see that PR for more info and comparative benchmarks).

  • calico

    Calico is a UI library for the Typelevel.js ecosystem. It leverages the abstractions provided by Cats Effect and FS2 to provide a fluent DSL for building web applications that are composable, reactive, and safe. If you enjoy working with Cats Effect and FS2 then I hope that you will like Calico as well. (by armanbilge)
