Reflex is a single page app framework written in Haskell compiled to JavaScript. A major concern with reflex is the slow loading times, this can be mediated however by doing server side rendering¹. This blog post will discuss how to do that².

The

In the previous blog post we saw interaction with servant in reflex. Although that covers the basics, there are several more hurdles to overcome to get comfortable with Reflex. I think most of these are encountered by building a simple login system. So let’s build something like:

In the pragmatic haskell series, we saw how to setup a simple webserver with database. But at some point you still need a frontend. If it were 2005 you may have been able to get away with just blaze. But we are in 2018+, and JavaScript is a problem

2. Pragmatic Haskell II: IO Webservant
3. Pragmatic Haskell III: Beam Postgres DB

Most Haskell language guides will leave IO until later. This guide is different, this guide is about using Haskell. Our focus is different: We build first, then learn trough delight.

There are many guides available for learning Haskell. Setting up a something simple like a web server isn’t so straight forward. Perhaps choosing one of the 14 libraries is a bit much.
