How to Install Node.js Essay Steps

This was the first in a series of posts leading up to Node.js Knockout on how to use node.js.

I have been given permission to repost the articles from the contest here (in wheat format) for general consumption. Expect more to come.

In this post we detail how to install node on Mac, Ubuntu, and Windows.

Mac

If you're using the excellent homebrew package manager, you can install node with one command: brew install node.

Otherwise, follow the below steps:

1. Install Xcode.
2. Install git.
3. Run the following commands:

darwin_setup.sh

git clone git://github.com/ry/node.git cd node ./configure make sudo make install

You can check it worked with a simple Hello, World! example.

Ubuntu

1. Install the dependencies:
   • sudo apt-get install g++ curl libssl-dev apache2-utils
   • sudo apt-get install git-core
2. Run the following commands:

ubuntu_setup.sh

git clone git://github.com/ry/node.git cd node ./configure make sudo make install

 Step 3 - Install NPM

Simply run the NPM install script:

curl http://npmjs.org/install.sh | sudo sh

And then check it works:

npm -v

You can check it worked with a simple Hello, World! example.

Thanks to code-diesel for the Ubuntu dependencies.

Windows

Currently, you must use cygwin to install node. To do so, follow these steps:

1. Install cygwin.
2. Use setup.exein the cygwin folder to install the following packages:
   • devel → openssl
   • devel → g++-gcc
   • devel → make
   • python → python
   • devel → git
3. Open the cygwin command line with Start > Cygwin > Cygwin Bash Shell.
4. Run the below commands to download and build node.

cygwin_setup.sh

git clone git://github.com/ry/node.git cd node ./configure make sudo make install

Hello Node.js!

Here's a quick program to make sure everything is up and running correctly:

hello_node.js

var http = require('http'); http.createServer(function (req, res) {   res.writeHead(200, {'Content-Type': 'text/plain'});   res.end('Hello Node.js\n'); }).listen(8124, "127.0.0.1"); console.log('Server running at http://127.0.0.1:8124/');

Run the code with the node command line utility:

> node hello_node.js Server running at http://127.0.0.1:8124/ 

Now, if you navigate to http://127.0.0.1:8124/ in your browser, you should see a nice message.

Congrats!

You've installed node.js.
