Installing Node.js

What is Node.js

Node.js is an open source, cross-platform runtime environment for server-side and networking applications written using JavaScript.

Installing Node.js

First please make sure you have Homebrew installed and fully updated, then installing Node.js should simply be a matter of doing:

First ensure homebrew is fully up to date

$ brew update

$ brew doctor

Then install node.js

$ brew install nodejs
... installation output

Check the install like this:

$ node --version
v0.12.0

$ npm --version
2.5.1

to update nodejs:
$ brew upgrade 

note from usman: when i did this last step i saw an old version for each of these since presumably i'd installed previously using some other method. using 'brew uninstall' and then installing again did not work, but following instructions here: https://gist.github.com/DanHerbert/9520689 did the trick.
