Sample program for Elm with Haskell warp server

Sample program for Elm with Haskell warp server.

elminator package is used for automatic generation of Elm types/encoder/decode from Haskell types.

How to build and run

1. Execute below commands:

stack build
elm make elm-src/Main.elm
stack exec elm-with-warp-exe

2. Access: http://localhost:8080

Development with ghci

Using reload command :r in ghci and update :: IO () function defined in app/DevelMain.hs, you can spare the build time for development. e.g.

$ stack ghci
*Main CodeGen DevelMain Lib Type> :r
*Main CodeGen DevelMain Lib Type> update

The update command will:

1. compile Main.elm by callCommand "elm make elm-src/Main.elm",
2. kill the previous server thread in ghci if any, and
3. start the new server thread in ghci
