This is a repo made for testing and development purposes for programs that depend on node.js
We just have to use the apt package manager.
sudo apt-get update
sudo apt-get install nodejs
If the package in the repositories suits your needs, this is all that you need to do to get set up with Node.js. In most cases, you'll also want to also install npm, which is the Node.js package manager. You can do this by typing:
sudo apt-get install npm
This will allow you to easily install modules and packages to use with Node.js.
