ReferenceError: localStorage is not defined
You can use standard API for localstorage, like
localStorage.setItem(key, val)
and
localStorage.getItem(key)
but If you want a angular solution for this and find a good library for localstorage, one I'm using is this
https://github.com/marcj/angular2-localstorage
also
https://www.npmjs.com/package/angular2-cool-storage
is cool to use.
The standard localStorage API should be available.
No need to declare it.
to setlocalStorage.setItem('name', 'storingSomething');
to getlocalStorage.getItem('name');
