A web server is essentially a function from a request to a response and so functional programming is a perfect fit for it. In this talk, I’m going to walk through a complete web development story with F#. We’ll start with a script file to test a couple of ideas, wrap the code into a web server and we’ll finish by deploying our system to Azure and Heroku.
