incremental-servant

This repository hosts the code to accompany my blog post where I describe a means by which an API can be incrementally and (mostly) transparently be converted to a Haskell servant API.

Getting Started

Ruby

You need ruby and bundler to run the server. Any version should work.

cd rubby
bundle install
ruby api.rb &

Let that process run, and it'll be serving up on localhost:4567.

Haskell

You need stack, which will take care of the rest.

stack setup && stack ghci

opens the REPL for use. In the master branch, startApp will run the application as a straight up reverse proxy, forwarding requests to localhost:8080 to localhost:4567. In the other branches, more and more functionality is assumed from the Ruby to the Haskell until eventually it's all taken care of.
