NPM

NPM (Node Package Manager) is the official Node.js package manager.

It is automatically installed with Node.js and is used to handle JavaScript (browser & Node.js) dependencies.

For those who knew bower, well, it's dead.

NPM allows:

• Dependencies management (just like apt, gem, maven, nugget, pip, yum...).

• JavaScript modules creation and publishing.

• Download and install of dependencies depending on a module's dependencies description.

• Sharing entry point scripts with developers and machines (e.g.: Continuous Integration) like build, debug, deploy, test etc...

We will use NPM once, to install Yarn...

... because it's better (Cf. Yarn).
