Haskell Web Development

We're writing a book on using Haskell for web development. The first book will cover building a simple Wiki with JavaScript? widgets and in-memory storage. The next volume will cover databases and persistence. There will likely be several volumes.


A beginning and intermediate programming environment based very deeply on LOGO, with the addition of the affordances modern hardware allows.

The core of the language is an artist robot. This robot can respond to basic commands as issued, or it can save them in list that can be passed around to other commands, much like the original LOGO. The environment will be extended to three dimensions in intermediate lessons.

The idea is to build this language as a Haskell DSL, and then evaluate that DSL on demand as permitted. The evaluation could take place in a simulator window, which would represent the robot carrying out the commands, including corrections required by physics, or by an actual flying robot with pens on a field of paper.

In another optional window would be a “telemetry” display, showing the physical state of the robots various components, such as motor speeds, position, velocity, calculated paths, and pen commands, and possibly even a first-person view from the robot camera. In an interactive setting with a real robot it would be pretty amazing to see the other people in the room as the robot’s camera scans them.

SICP for Haskell

Another idea is porting SICP to Haskell, and also extending it to gradually introduce type theory. First we’d start off leaning entirely on type inference, and then slowly expand examples to include type signatures and advanced type concepts.
