todosapp is a sample application that manages your to-do items. It is built primarily to explore the server-side asynchronous programming in JVM web frameworks. It is inspired by todomvc, a browser-side sample application to showcase MV* JavaScript frameworks.

You can find more info in my article "Develop Non-Blocking Web Applications in Java".

In the sub-projects, we build the sample project using the following frameworks respectively:

• Java EE: Servlet and JAX-RS
• Spring MVC, with Spring Data and Spring Boot
• Vert.x 2.0 for Java
• Play 2 Framework for Java

Once running, the web application can be accessed at its homepage

 http://localhost:8080

There are actually three "applications" packaged in each sub-project:

• Web application rendered at the server side:

  http://localhost:8080/todos

• RESTful Web Service providing CRUD operations of to-do items:

  http://localhost:8080/api/todos

• Single-page application: a rich Internet client rendered at the browser side:

  http://localhost:8080/spa

  This is a Backbone.js application backed by the RESTful web service at api/todos.

All modules are implemented in Java 8, taking advantage of the Lambda expressions.

###Maven Integration

The build system is Maven. Maven 3.2.2 or newer should be used. Older versions of Maven can result in CDI linkage errors.

To build all sub-projects, run

mvn clean install

Each application can be deployed and run on its embedded application server with an in-memory database directly from Maven. Refer to the instruction in each project for how to run the application.

The project is built using Maven. You can open it in any of your favorite IDE.

If you open the module as a Maven project in NetBeans, you can leverage NetBeans integration with Maven to run NetBeans command Clean, Build, Run and Debug.
