I looked around, but could not find a lot of routing packages for WAI. There is wai-routes, but QuasiQuote makes me nervous.

So, I hacked together a very simple router (attached). It works, though it is not efficient for large routing tables (it just does a linear scan over all possible routes in the worst case).

I'm curious: (a) what are other people using? (b) are there glaringly stupid things I've done in my code?

Thanks :)

I use plain case expression to do routing for my simple wai applications, ghc's desugar can make it more efficent than linear scan, the code is like this:

case (requestMethod req, pathInfo req) of

("GET", []) -> index

("GET", ["object", pk]) -> getObject pk

("POST", ["object", pk]) -> jsonBody >>= updateObject pk

_ -> bad status404 "no route match"
