Npm install on OSX

Hint

You may not need this at all, if you are using runTests.sh with dockerized environment for building all assets.

Head over to https://docs.npmjs.com/cli/ and follow the install instructions.

Once you have installed it, you can open up the Terminal app which is located under Applications/Utilities on your mac. Once in the terminal, type npm -v to get the version number of npm that is currently running on your machine.
