Introduction to Node.js by M Richard
This book is intended to explain a basic concept of node.js
just how to get started with node.js
Like most starter they wonder what can node do and how to
move from console to something tangible like application this was the question
I had when I first started learning node I mean this is real for almost all
programmers
Who is this book for?
This book is for absolute beginners as is my first version
of my node.js publication
And while learning this I hope you have understanding of
javascript or jQuery with some understanding of html and css but not necessary.
Why learning node.js
As technology grow every day programmers need to keep up to
date with most powerful and strong technology that simplify thing and do thing
in good manner that is why you have to learn node.js
Get started
First download node.js at official node website and install
it your PC or MAC www.nodejs.com
Or get a link here www.coursestreamer.com
How node.js work?
Node.js use http request to send and receive data through
GET and POST method
And trust me all this happen in background means in
interesting way! I really like it.
Let see this code: var http=require("http");
http.createServer (function (request,
response) {
response.writeHead (200,
{"context-type”: text/plain"});
Response. Write ("hello
world");
Response. End ();
}).listen
(8888);
Before
explaining the above code let me talk about what we call module
There is
built-in module this comes with node.js which stands for library and parser at
the same time
We started
creating variable named http that require http module to allow us to use http
request for our application
And we used
createServer to help us creating server listening on specific port here we used
port 8888 which can be any port according to our choice.
Running our Codes
We installed
our node.js and we have node running on our environment start and choose
working folder that currently your project reside
Here is how I
get on my path: cd c: //xampp/htdocs
I am using
htdocs as where my files reside
I saved the
above code as starter.js
Return to
node application and run this code: node starter.js
Go to your
browser and run http://localhost:8888
And see the
result that is to say our application is listening on port 888
And it can
receive and respond to any request.
In next article we will see how to structure
our application and how to create our own module rather than using built in
module and this book is written by request of article and according to what the
reader of this book need so please send your request at these emails: richard@youthoughts.com , beastar457@gmail.com and learn for free
