Where the fuck is LocalStorage in AngularJS 2?!

So I’m a new migrator from AngularJS1/Ionic1 to AngularJS2/Ionic 2.

Already I’m working on a new production project while learning on the job, and so far so good, until I ran into my post login processes, where I needed to store the logged in user info in the app, which traditionally would be done with LocalStorage, built in, in Ionic Framework 1.

To my dismay, there are ZERO docs on localStorage in AngularJS 2/Ionic Framework 1, nor the built in Storage service it provides. I managed to only learn about Storage-LocalStorage from a Udemy tutorial and searches, and turns out the way to import the service was wrong in most of the results.
