Day 13: DropWizard–The Awesome Java REST Server Stack

I have mainly been a Java guy throughout my 8 years as a software developer. For most of the applications I have written, I used the Spring framework or Java EE. Lately, I am spending time learning web development in Python, and one thing that has impressed me a lot is the Flask framework. The Flask framework is a micro-framework which makes it very easy to write REST backends. Today for my 30 day challenge, I decided to find a Java alternative to Python’s Flask framework. After doing some research, I discovered that the DropWizard framework can help me achieve the same productivity as the Flask framework. In this blog, we will learn how to build a RESTful Java MongoDB application using DropWizard. Read the full blog here

Building Single Page Web Applications with Backbone.js, JaxRS, MongoDB, and OpenShift

Backbone.js is a mature, popular, and lightweight javascript library which aims to bring structure to your client-side code. The goal of backbone.js is to bring MVC, a software architecture pattern, to client side development.Actually, backbone.js is an MV framework where view is also responsible for controller logic as well. In this blog, we will build a simple social bookmarking application.

In brief, MVC is a programming design pattern for separating the different concerns of your application. The M corresponds to Model and is used to define domain object. The V corresponds to View and is responsible for display logic. Finally, the C corresponds to Controller and is responsible for user interactions and interactions between Views and Models.

You can find source code of the application here Backbone.js is used by Linkedin, Foursquare, Wunderkit, Groupon, etc to build complex applications. You can view the full list here.

How To Build Real-Time Location-Aware Applications using MongoDB , WebSockets , and HTML 5 GeoLocation API

One of the advantages of OpenShift or any other Platform as a Service is that it gives developers the power to turn their ideas into applications. As a developer, you are only concerned about writing code and the platform manages and scales the underlying infrastructure for you. I am also a developer and I love to write code.

A few days ago, I came up with a very simple idea to show messages in real-time on a map. A user posts a message via the application user interface, the application captures the user’s current location using an HTML5 Geo-location API, and then displays the message on a map. If another user posts a message from some other part of world, the first user will see that same message in real-time. As users start posting messages, they will see all of the messages appearing on the map.
