An functional and compositional approach to web applications via bidirectional transformation.

In order to build the project, cabal and nix are necessary.

Since the project is based on miso library, we also need to use the cachix for miso with following code:

nix-env -iA cachix -f https://cachix.org/api/v1/install
cachix use miso-haskell

Then we can install the project:

• Clone the project
• Execute nix-shell to enter the development environment
• Execute cabal build app --ghcjs to build the task management application
• Open app.html to see the result.

• Elmlens.hs defines the ElmApp with combinators.
• Apps.hs defines some simple examples.
• Todo.hs defines the themed task management application.
