How to set up a simple web service
You will learn how to setup a simple web application.
We will be using the Servant web framework to demonstrate how to write web applications in Eta.
Servant uses the powerful strong typing features of Eta to provide a type-safe DSL that allows you to write web applications and services in a rock-solid way.
Note that Servant is a Haskell web framework. Because of the eta-hackage patching layer, the framework has been patched to work with Eta.
The Servant framework makes heavy use of type-level programming, which can be thought of as a type-safe, composeable, extensible macro system in Eta. Using the framework does not require a deep understanding of type-level programming.
We will learn the basics of the framework.
