In our Angular apps, remembering user-preferred settings is an excellent way to provide a good experience for the users. We can save data in the user's browser using the localStorage object, which provides methods for working the key-value data.
Local storage is client-side storage for web applications. It stays there as long as it's not cleared—unlike session storage, which lasts for the current browser tab session. Local storage provides up to 5MB of storage, allocated separately for each domain.
There are four basic JavaScript methods you can use to access and work with localStorage: setItem() - takes a key-value pair and adds it to localStorage. getItem() - takes a key and returns the corresponding value. removeItem() - takes a key and removes the corresponding key-value pair.
AngularJS Service: Using window.localStorage directly is just fine, but having to set and parse Strings gets tiresome after a while. Use this simple AngularJS service for setting and retrieving strings or objects easily:
angular.module('ionic.utils', [])
.factory('$localstorage', ['$window', function($window) {
return {
set: function(key, value) {
$window.localStorage[key] = value;
},
get: function(key, defaultValue) {
return $window.localStorage[key] || defaultValue;
},
setObject: function(key, value) {
$window.localStorage[key] = JSON.stringify(value);
},
getObject: function(key) {
return JSON.parse($window.localStorage[key] || '{}');
}
}
}]);
And to use this service, just inject the $localstorage service into a controller or run function:
angular.module('app', ['ionic', 'ionic.utils'])
.run(function($localstorage) {
$localstorage.set('name', 'Max');
console.log($localstorage.get('name'));
$localstorage.setObject('post', {
name: 'Thoughts',
text: 'Today was a good day'
});
var post = $localstorage.getObject('post');
console.log(post);
});
