Starting with Node Js

Installing node.js in Virtual Machine.

After running the virtual machine, ssh to it.

I am using the NVM(Node Version Manager) to install the node. So we can install the version we want.

Anyway I have just installed the latest version.

First we need to install the NVM.

So take the terminal and follow the steps in the below link.

https://www.liquidweb.com/kb/how-to-install-nvm-node-version-manager-for-node-js-on-ubuntu-12-04-lts/

so after installing nvm we can install the desired node js version

I have installed the latest version  by using the below command

nvm install node

for more info about installing node check the below link:

https://www.sitepoint.com/quick-tip-multiple-versions-node-nvm/

After restarting the terminal if you see any error when running the command 'node' from the terminal like the following :

"The program 'node' can be found in the following packages:

 * node

 * nodejs

Try: apt-get install <selected package>"

then use the command : nvm use node

As I am using Virtual machine I need to update the server code slightly to get the node run in the main browser that is not in virtual machine

I have created the server using the below code.. check the listen section, where I put the IP address of the virtual machine.

var http = require("http");

http.createServer(function (request, response) {

   // Send the HTTP header 
   // HTTP Status: 200 : OK
   // Content Type: text/plain
   response.writeHead(200, {'Content-Type': 'text/plain'});
   
   // Send the response body as "Hello World"
   response.end('Hello World\n');
}).listen(8081, '192.168.56.102');

// Console will print the message

console.log('Server running at http://192.168.56.102:8081/');

Now you can start develop your own code..
