Elm frontend for my polyglot CRUD project

Example frontend CRUD project in Elm.
See my CRUD umbrella project: typesafe-web-polyglot.

Features:

• Almost (since this is Elm) polymorphic CRUD
  • code reuse across crud-ed entities
  • CRUD components agnostic of each other existence
• Type safe Web
  • Typed Web API for server interaction
  • Client-side typed dispatch API using hash URL fragments
  • Optional use of servant generated code (see crud-ex-backend-servant and FromServant.ThingApi).
• Almost-SPA / SPA design

Other Features:

• Customizable logging of elm runtime interactions

TODO List:

• List pagination support
• Keep rethinking styling and views
  • should I keep using purecss?

Git:
I am using submodules to get dependencies/elm-purecss, elm-purecss project is not available as elm 0.18 package dependency.

Backend companion projects:
crud-ex-backend-yesod.
crud-ex-backend-servant
crud-ex-backent-http4s

To Run in elm-reactor:
0. Install Elm Platform

1. Start backend server (see backend instructions).
2. start elm-reactor
3. point browser to elm-reactor.html

How to Deploy to Yesod:
This primitive and ugly elm_deploy_to_yesod.sh script assumes folder structure in which this project and the yesod project share the same parent folder.

How to Deploy to Servant:
Included primitive elm_deploy_to_servant.sh script assumes folder structure in which this project and the servant project share the same parent folder.

Conclusions (so far):

• I like Elm a lot 🎆. Combines FP and simplicity!
• Would like to see
  • more stable language API
  • package manager working with ported (JS FFI) projects
  • language polymorphism (is it FP without denotational abstractions? laws? proof obligations?)
