How to pass a simple array data in ngStorage,$localstorage?

So lets say I want to define an var array=['a','b','c']

How do I pass this array into localStorage ?

Should I just simply write $localStorage.data = array;?

And also how to check if that array $localStorage.data is not empty and not undefined?

Yes, you simply put it like this:

$localStorage.data = array

And also how to check if that array $localStorage.data is not empty and not undefined?

Check it like simple variable

if($localStorage.data){
    console.log('empty');
} else{
    console.log('Data', $localStorage.data);
}

ngStorage

Right from AngularJS homepage: "Unlike other frameworks, there is no need to [...] wrap the model in accessors methods. Just plain old JavaScript here." Now you can enjoy the same benefit while achieving data persistence with Web Storage.

You can simply store in localstorage as:

localStorage.setItem("data", JSON.stringify(array));

and later retrieve it as

$scope.data= JSON.parse(localStorage.getItem("data"));

You can check $scope.data by doing

console.log($scope.data);
