Build

You need nix packet manager to build the repo with GHCJS.

Backend

The following instructions allow to build backend incrementally.

• Enter GHC environment, where all dependencies for backend and frontend are configured to use GHC:

nix-shell -A shells.ghc

• Compile with cabal new-build:

cd app-back
cabal new-build exe:app-back

• Run result with server.sh script.

• You can use ghcid for hot recompilation:

ghcid -c "cabal new-repl lib:app-back"

Or for executable:

ghcid -c "cabal new-repl exe:app-back"

Frontend

The following instructions allow to build frontend incrementally.

• Enter GHC environment, where all dependencies for backend and frontend are configured to use GHCJS:

nix-shell -A shells.ghcjs

• Compile with cabal new-build:

cd app-front
./build.sh

• In backend environment run server with ./serve.sh script in app-back folder as current.
• Now open http://127.0.0.1/index.html in your browser.
