angular2-local-storage | Angular 2 module that gives access | Storage library

It took about 10 hours since I am trying some simple jobs using typescript, angular2 and asp core. I will explain the path I reached here and where you have any idea i will appreciate.

First you should consider that I am using a project template from the link bellow:

Template

Then I wanted to add some code to store some data in localStorage.

Some links suggest that I must have access to localStorage very simple. But when I wanted to access localStorage from within the component of angular2, I got this error:

localStorage is not defined

Then I googled a lot for a solution and found libraries below:

angular2-localstorage

angular-2-local-storage

angular2-local-storage

But all of them won't work.

Then I tried writing a service will the hope of accessing localStorage easily. Then I created this file:

/ClientApp/app/services/local-storage-service.ts
