Sample program for PureScript with Haskell warp server

Sample program for PureScript with Haskell warp server.

purescript-bridge package is used for automatic generation of PureScript types/encoder/decode from Haskell types.

How to build and run

1. Execute below commands:

npm install virtual-dom
npm install browserify

spago bundle-app && browserify index.js > main.js

stack build
stack exec purescript-with-warp-exe

2. Access: http://localhost:8080

Development with ghci

Using reload command :r in ghci and restart :: 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. auto generate pureScript-src/src/Type.purs file from haskell src/Type.hs.
2. kill the previous server thread in ghci if any, and
3. start the new server thread in ghci
