Enjoy Typesafe Web Development with Eta
summary
Demo shows building a small web backend in Eta (Haskell on JVM) using gradle/atlas.run and Docker to resolve dependencies. Code implements a fibonacci API and a JSON hello endpoint running on localhost:9000 and the demo requests return correct values. Compiler error messages and strong static types enable confident refactors and easier concurrency. Caveat: Eta tooling and package hosting are shaky so builds require Docker and careful Haskell dependency selection. atlas.run is used to fetch and run the project.
