How to install Node.js on Raspberry Pi 2 and create a simple Webserver to Host a static Website
When you work to build a modern website based only on HTML5 and
> Javascript, you don't need complex configurations to verify how the
> end user will display the web site. A simple web server serving
> static files is the fastest and easiest solution, in this guide we
> will learn how to install Node.js and create a simple web server to
> use for our work. Node.js is a runtime environment for developing
> server-side web applications. In simple words, the Node.js platform
> makes it possible to run JavaScript programs on a server and also on
> your Raspberry Pi 2.

> First of all, please run the following command in a shell or
> terminal
>
> sudo apt-get update
>
> Please wait! This command can be very slow, it downloads the package
> lists from the repositories and "updates" them to get information on
> the newest versions of packages and their dependencies.
>
> Remove a program with similar name to node.js (it creates conflicts,
> so better remove it)
>
> sudo apt-get --purge remove node
>
> To install Node.js run the commands
>
> sudo apt-get install nodejs
> sudo apt-get install npm
>
> Nice job! You have sucessfully installed nodejs and npm in your
> Raspberry Pi 2. You can see the version currently being used by the
> shell by typing:
>
> node -v
>
> If nothing happens and you have the error node: No such file or
> directory create a symlink with the command
>
> sudo ln -s /usr/bin/nodejs /usr/sbin/node
>
> Create a folder called /var/www/ and navigate to that folder, it
> will be our work directory.
>
> sudo mkdir /var/www
> cd /var/www
>
> We are ready to start coding! We will create a simple Webserver to

>
> npm install --save compression connect http serve-static
>
> Create a folder called httpdocs, this folder will cointain your HTML
> file, images and js code you want to host.
>
> sudo mkdir /var/www/httpdocs
>
> For example create a file index.html
>
> Create in /var/www a file named server.js and put this code inside:

If
you followed all the steps, typing the ls command you can see this
> dicrectory structure
>
> httpdocs node_modules server.js
>
> To start the web server, execute the script with the command
>
> node server.js
>
> This will create a local webserver running on port 8181, if you
> write this web addess in your browser
> http://localhost:8181/index.html you will view your website running
> (remember to put your files in /var/www/httpdocs folder). To stop
> running the server press ctrl + c
>
> Do you want to make available your website directly on the Internet?
