A simple ToDo app to demonstrate Maven, App Engine (Java), Objectify, GSON, AngularJS, and Twitter Bootstrap.
Many standard features are implemented such as tabbed navigation, user authentication, data security, client-side filtering, etc. This project is intended to be a good starting place for building more comprehensive web applications.
I'm currently working on: (1) a custom AngularJS directive that displays a D3.js chart with some summary statistics; (2) a data access object hierarchy for cleaner datastore access; and (3) REST services to replace the servlets.
