wreq-stringless: Simple wrapper to use wreq without Strings

This Haskell library wraps Network.Wreq to use the functions without Strings.

You can use:

  • Data.Text
  • Data.Text.Lazy
  • Data.ByteString.UTF8
  • Data.ByteString.Layz.UTF8

for all functions from Network.Wreq where the original implementation use Strings.


{-# LANGUAGE OverloadedStrings #-}
module Main where

import qualified Data.Text               as T
import           Lens.Micro.Extras       (view)
import qualified Network.Wreq            as Wreq
import qualified Network.Wreq.StringLess as Wreq'

-- say we use a alternate prelude like 'Protolude', and we don't use Strings
-- or we have the url from somewhere else, and it's not a String.
url :: T.Text
url = ""

main :: IO ()
main = do
  -- with plain wreq
  view Wreq.responseStatus  <$> Wreq.get (T.unpack url) >>= print

  -- with wreq-stringless - no manual conversion necessary
  view Wreq'.responseStatus <$> Wreq'.get url >>= print

How to use it:

  • replace your wreq dependency with wreq-stringless
  • replace the import Network.Wreq with Network.Wreq.StringLess
