Hello world

Here is an example of running simple application using Warp server:

{-# LANGUAGE FlexibleInstances      #-}
{-# LANGUAGE MultiParamTypeClasses  #-}
{-# LANGUAGE OverloadedStrings      #-}
{-# LANGUAGE TypeApplications       #-}
{-# LANGUAGE TypeSynonymInstances   #-}

import Control.Exception (SomeException)
import Data.Function ((&))
import Data.Text (Text, append)
import Linnet
import Network.Wai.Handler.Warp (run)

-- It's necessary to define encoding of exceptions for content-type "text/plain". Here it returns no content
instance Encode TextPlain SomeException where
 encode _ = mempty

helloWorld = get(p' "hello" // path @Text) ~>> (\name -> return $ ok ("Hello, " `append` name))

main :: IO ()
main = run 9000 app
       where app = bootstrap @TextPlain helloWorld & compile & toApp id

Now try to call your application with:

curl -v http://localhost:9000/hello/linnet
