Readme for bird-0.0.7

[back to package description]


A sinatra-ish web framework written in haskell, riding on top of Hack.


Sinatra has a beautiful, simple, elegant syntax, but it's essentially an attempt to bring pattern matching to a language never intended for pattern matching. Why not attempt something similar in a language with not just beautiful pattern matching, but with all the declarative bells and whistles: lazy evaluation, first-class functions, currying, polymorphism?


λ cabal update && cabal install bird

Note: make sure $HOME/.cabal/bin is in your PATH.

Create an app

λ bird MyApp 

Compile your app

λ cd MyApp
λ bird nest 

Start your app (runs on port 3000)

λ bird fly

Try it out

λ curl http://localhost:3000
  404 Not Found


-- MyApp.hs
module MyApp where
import Bird
import Data.String.Utils

get, post, put, delete :: Path -> BirdRouter ()
get ("howdy":xs) = body $ "Howdy " ++ (join ", " xs) ++ "!"

get ["droids"] = do
  body "Nothing to see here. Move along."
  status 404

get _ = status 404
post _ = status 404
put _ = status 404
delete _ = status 404


λ curl http://localhost:3000/howdy/there/pardna
    Howdy there, pardna!

λ curl http://localhost:3000/droids
    Nothing to see here. Move along.
