Reaping the Benefits of Node
J2ee developers can reap immense benefits through Node because it possesses the ability to manage concurrency and it was primarily constructed keeping in mind web development. One of the most popular Node tools is the web development framework called Express, which boasts a rich amalgamation of features and help outsourced Java development teams to capitalize on aspects such as complex routing, content negotiation and dynamic template views. Besides, which it is extremely lightweight and does not need any kind of additional ORM or similar programming package. One of the most convenient ways to install Express is to make it a dependency through an NPM package.json file. Most J2EE developers will agree the ideal coding for his will be:
{ "name": "magnus-server", "version": "0.0.1", "dependencies": { "express": "2.4.6" } }
Listing 2:
The next step is to write the sample application, which is called Magnus Server through a JavaScript file. The outsourced Java development team can name the file anything and open the file on any of the editor or IDE. Once ...
... the file is opened, J2EE developers need to add the following code that is listed. This particular block of code is meant to achieve some big objectives. For instance if there is the requirement of using a third-party library in Node, offshore Java developers need the Express framework and also need to manage it through the express variable. Next, there is a requirement to develop an instance through the createServer call, which then creates an HTTP server. The next step is to define endpoint through via.app.put, and this put has two parameters where the first one is the route and the callback to be executed and the second one is a function that can be invoked at runtime.
var express = require('express'); var app = express.createServer(express.logger()); app.put('/', function(req, res) { res.contentType('json'); res.send(JSON.stringify({ status: "success" })); }); var port = process.env.PORT || 3000; app.listen(port, function() { console.log("Listening on " + port); });
Listing 3:
Since JSON and JavaScript are closely related therefore most J2EE developers will realize it is quite convenient to manage JSON in Express and a bit more code is added to Listing 2.
{ "deal_description":"free food at Freddie Fingers", "all_tags":"free,burgers,fries" }
Listing 4:
This particular listing is about Java development team to add functionality to parse the incoming document. Since there is a line that directs Express to use bodyParser, therefore it will be convenient to borrow the attributes from an incoming JSON document.
app.use(express.bodyParser()); app.put('/', function(req, res) { var deal = req.body.deal_description; var tags = req.body.all_tags; console.log("deal is : " + deal + " and tags are " + tags); res.contentType('json'); res.send(JSON.stringify({ status: "success" })); });
Finally the Java development team can test the implementation too and all they need to do is first stop and then restart the magnus-server instance and then use an HTTP PUT to submit a JSON document to Express application. The test will be called successful, if J2E developers witness a successful response and secondly Express should be able to log on to standard out the values that have been submitted and therefore with the above line of coding, this is what one will get:
‘’Deal is: free food at Freddie Fingers and tags are free, burgers, fries.’’
