How to do it...

1. Create a new project called using-hedis with a simple stack template:

        stack new using-hedis simple

2. Add a dependency on the hedis library in the build-depends sub-section of the executable section. Also add a dependency on the bytestring package:

 executable using-hedis
   hs-source-dirs:      src
   main-is:             Main.hs
   default-language:    Haskell2010
   build-depends:       base >= 4.7 && < 5
                       , hedis
                       , bytestring

3. Open src/Main.hs. We will be adding our source here.

4. Add an initial module declaration and import the required headers. Enable OverloadedStrings as we will be dealing with ByteString in this recipe:

 {-# LANGUAGE OverloadedStrings #-} module Main where import Database.Redis import Data.ByteString.Char8 as B import Control.Monad import ...
