npm

node must first be installed, using apt-get or installer. To ensure last version of npm is installed, run this :

sudo npm install npm -g

If there is already a package.json, npm packages can be installed using :

npm install

If there is no package.json, it can be created using :

npm init

Then, dependencies can be added using :

npm install --save-dev
npm install --save

For a non-node project, --save-dev will almost allways be used.

BOWER

Bower must first be installed globally for the command bower to work :

npm install -g bower

An empty bower.json file can be created using :

bower init

If there is a bower.json, its packages can be installed using :

bower install

Then, dependencies can be added using :

bower install --save <package>

Or removed using :

bower uninstall <package>

GULP

To run browser_sync, use :

gup serve
