Play 2.3.0 application with ReactiveMongo – reactive, asynchronous and non-blocking Scala driver for MongoDB.

This is a classic CRUD application, backed by a MongoDB database. It demonstrates:

Achieving, Futures to use more idiomatic error handling.
Accessing a MongoDB database, using ReactiveMongo.
Achieving, table pagination and sorting functionality.
Replaced the embedded JS & CSS libraries with WebJars.
Play and Scala-based template engine implementation
Bootswatch-United with Twitter Bootstrap 3.1.1 to improve the look and feel of the application

Instructions :-

The Github code for the project is at : playing-reactive-mongo
Clone the project into local system
To run the Play framework 2.3.0, you need JDK 6 or later
Install Typesafe Activator if you do not have it already. You can get it from here: download
Execute activator clean compile to build the product
Execute activator run to execute the product
playing-reactive-mongo should now be accessible at localhost:9000

References :-

This is the start, from next week onwards we would be working on this application to make it grow. We would look at how we can make it more functional, then we would be adding more modules to it together. If you have any changes then feel free to send in pull requests and we would do the merges 🙂 Stay tuned.
