Microsoft's New Language "TypeScript"

After the Google's Dart Microsoft has responded with the "TypeScript"  yet another language that compiles to javascript. TypeScript provides many features for example type inference and concept of classes and modules which have also been proposed by Ecmascript 6 (ES6).

Having said the pleasantries, lets do what we really like to do that is to say hello ... one thing that i really love about Microsoft is that is provides great tooling support, you can download and install the TypeScript editor plugin that integrates with Visual Studio 2012 and provide you with the ready to run TypeScript Application template. TypeScript also provides support for other editors

After you have installed the TS plugin for VS2012 you can fire up the studio and find the TS application template under Visual C# Installed Project templates.

After the project has been successfully created you can simply hit f5 to launch the application and see the greeting message

Another highlight, developers familiar with c# may not find it a new thing but, the use of lambdas to represent the anonymous functions is quite intriguing.

 There is no need to share this getting started code because we have not added a single line of code to the auto generated application code by VS2012.

 The TypeScript is developed on codeplex where you can browse the source code

Create a simple HTTP server with Node.js

With so much of the hype of node.js and the server side javascript i decided to give it a go, the post is not really as complicated as the title may look like, node.js allows you to get real taste of the core protocols which we tend to ignore while using frameworks, though there are some good application frameworks for building node applications like Express and Geddy but in the initial stage one should learn the way it really works out IMO... so without fuether ado lets get down to writing the http server, i assume that you have success fully installed node.js HERE is a useful link.

After the installation you can check the version of the node by typing

node -v

into the terminal window, i'm using fedora 15 (lovelock). Ok now create a file and name it server.js and put the following code inside it

var http = require("http");

http.createServer(function(request, response) {

  response.writeHead(200, {"Content-Type": "text/plain"});

  response.write("Hello Node");

  response.end();

}).listen(8088);

in-order to listen to port 80 you would require the root privileges so i'm not getting into that.

 The first line of code is used to include pre-build module of http more on node modules in the later posts...

the rest is very obvious, cd to the directory where server.js is residing and type

[fedora@localhost HelloNode]$ node server.js

 now  just redirect your browser to

 http://localhost:8088

and it will greet you with the

message "Hello node"...

Congratulations you have made yourself a http server

P.S i took help from this guide
