chatty - a chat demo that evaluates several technologies (and hopefully shows best practices)

• Java 8 (This demo will not run with any Java < 8)
• [HAL] (http://stateless.co/hal_specification.html) (RESTful Hypermedia API)
• [Atmosphere] (https://github.com/Atmosphere/atmosphere) (Async Pub/Sub)
• [Jersey] (https://jersey.java.net/) (JAX-RS reference implementation)
• [TypeScript] (http://www.typescriptlang.org/) for web client
• [AngularJS] (http://angularjs.org/) for web client
• [Protractor] (https://github.com/angular/protractor) for functional web client UI tests
• [JUnit] (http://junit.org/) for Java unit and integration testing
• [Mockito] (https://code.google.com/p/mockito/) for Mocking
• [Gradle] (http://www.gradle.org/) as build system

• Java 8 JDK installed
• Node.js installed
• Grunt CLI installed (npm install -g grunt-cli)
• Bower installed (npm install -g bower)
• TSD (TypeScript Definition Manager) installed (npm install -g tsd)

• ./gradlew build (builds all and runs the integration tests, both Java and TypeScript)
• ./gradlew startServerSync (starts a Jetty server using port 8080)
• Open http://localhost:8080/src/main/webapp/chatty.html in a web browser
• Open http://localhost:8080/src/main/webapp/chatty.html in another web browser
• Play around with chatty!

Here is an example what you get at http://localhost:8080/chatty/api/users. Currently I am using [HAL] (http://stateless.co/hal_specification.html). The returnd mime type is "application/hal+json". To get a pretty print in Chrome, please install the Chrome extensions [JSONView] (https://chrome.google.com/webstore/detail/jsonview/chklaanhfefbnpoihckbnefhakgolnmc) and "application/...+json|+xml as inline"

  _links: {
    self: {
      href: "http://localhost:8080/chatty/api/users",
      hreflang: "en",
      profile: "chatty"
    }
  },
  _embedded: {
    users: [
      {
         _links: {
           self: {
             href: "http://localhost:8080/chatty/api/users/toedter_k"
           }
         },
         email: "kai@toedter.com",
         fullName: "Kai Toedter",
         id: "toedter_k"
      }
    ]
  }
}

• More tests
• Better TypeScript integration
