JavaScript for Line of Business Applications

As the title states, we are going to discuss how to build an RFID-based asset tracking system using popular open source tools like Node.js and MongoDB. For the sake of simplicity, let’s start with a very basic model of a system addressing only a general concern of getting some information from RFID hardware and putting it in the database. Of course, in real life we would have to think about many details and additional components to take into account security, bandwidth consumption, monitoring, etc., but let us forget about it all for now and get back to these aspects in our future posts.

In this example, we look at how real-time Web communications can work well with a non-blocking JavaScript back-end server and a NoSQL database. Our demo is a simple drawing app.

If all you use is WebSocket with simple pub-sub messaging, you can already achieve pretty amazing things with drawing. For example, you can share a drawing board among multiple browser clients and while viewing each other’s drawings in real time.

Current post is a proof of concept towards make a web application with Javascript based Web Server.

To make this possible, we have selected -

1> Angular.js for client side development – Single Page Application

2> Cross Domain Communication in between Angular.js and Node.js

3> Node.js for server side development

4> Rest based web service creation with express.js

5> Database – MongoDb

6> Node.js MongoDb Module Extention (mongojs)

We have created a Proof of Concept with Javascript based web server, where we have focused on dealing with NoSql (MongoDB) with javascript based framework Node.js and angular.js on client side.

Join Josh Owens as he builds a Meteor.js app from scratch using Ratchet, Cordova, and MongoDB.

MEAN stack is a full JavaScript solution that helps you build fast, robust and maintainable production web applications using MongoDB, ExpressJS, AngularJS and Node.js.
Sails.js allows you to build custom, enterprise-grade Node.js apps using the Model-View-Controller pattern to organize your code so it is easier to maintain.
New MEAN Stack = MongoDB+ExpressJS+AngularJS+Node.js+Sails.js = MEANS stack

ou're going to need to know how to get a webserver running with Express, and how to use app.get and app.post to communicate with both the server and the database. It's all covered in that original tutorial, and if you're a developer who's familiar with JavaScript, it's not hard.

Back? … or rolling your eyes and going, “dude, I already know that stuff”? Either way, great! Let's add some new tools to our toolbox, and create a simple little app that works without a single page refresh.
Here are the goals:
* Learn what REST means in plain English
* Store and retrieve JSON data in a MongoDB collection using HTTP POST and HTTP GET
* Remove data from the collection using HTTP DELETE
* Use AJAX for all data operations
* Update the DOM with jQuery

PART 1 - SERIOUSLY, WHAT THE HELL IS REST?
PART 2 - SETUP
PART 3 - STARTING IN ON HTML
PART 4 - THE DATABASE
PART 5 - LISTING USERS
PART 6 - POPULATING USER INFO
PART 7 - ADDING USERS
PART 8 - DELETING USERS
CONCLUSION

This application is another proof of concept towards make a web application for graph generation with Javascript based Web Server.
In this application we have used following tools and technologies -
1> Node.js for server side development
2> Rest based web service creation with express.js
3> Database – MongoDb
4> Node.js MongoDb Module Extention (mongojs)
5> Highchart.js for Graph generation through Asynchronous call (Ajax)
6> Using Cross-Domain policy to access REST service from Node.js to Ajax Call
We have created a Proof of Concept with Javascript based web server, where we have focused on dealing with NoSql (MongoDB) with javascript based framework Node.js.
