Warnings:

'ghc-options: -O2' is rarely needed. Check that it is giving a real benefit and not just imposing longer compile times on your users.

Enables the declaration of "routes" which handle requests to a specific URL.

The set of possible handlers can be restricted by "predicates", which operate on WAI requests and have to be true or else the handler will not be called.

Example:

import Data.ByteString (ByteString)
import Data.Text (Text)
import Network.Wai
import Network.Wai.Predicate
import Network.Wai.Routing
import Network.Wai.Handler.Warp

main :: IO ()
main = run 8080 (route (prepare start))

start :: Monad m => Routes a m ()
start = do
    get "/user/:name" fetchUser $
        capture "name"

    get "/user/find" findUser $
        query "byName" ||| query "byId"

    delete "/user/:name" rmUser $
        capture "name" .&. opt (cookie "foo")

fetchUser :: Monad m => Text -> m Response
fetchUser name = ...

findUser :: Monad m => Either ByteString Word64 -> m Response
findUser (Left  name)  = ...
findUser (Right ident) = ...

rmUser :: Monad m => Text ::: Maybe Int -> m Response
rmUser (name ::: foo)  = ...
