##Get Started (1) You can install angular-local-storage using 2 different ways:
Git: clone & build this repository
Bower:

$ bower install angular-local-storage

npm:

$ npm install angular-local-storage

(2) Include angular-local-storage.js (or angular-local-storage.min.js) in your index.html, after including Angular itself.

(3) Add 'LocalStorageModule' to your main module's list of dependencies.

When you're done, your setup should look similar to the following:

<!doctype html>
<html ng-app="myApp">
<head>
   
</head>
<body>
    ...
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js"></script>
    <script src="bower_components/js/angular-local-storage.min.js"></script>
    ...
    <script>
        var myApp = angular.module('myApp', ['LocalStorageModule']);

    </script>
    ...
</body>
</html>

##Configuration ###setPrefix You could set a prefix to avoid overwriting any local storage variables from the rest of your app
Default prefix: ls.<your-key>

myApp.config(function (localStorageServiceProvider) {
  localStorageServiceProvider
    .setPrefix('yourAppName');
});

###setStorageType You could change web storage type to localStorage or sessionStorage
Default storage: localStorage

myApp.config(function (localStorageServiceProvider) {
  localStorageServiceProvider
    .setStorageType('sessionStorage');
});

###setStorageCookie Set cookie options (usually in case of fallback)
expiry: number of days before cookies expire (0 = does not expire). default: 30
path: the web path the cookie represents. default: '/'

myApp.config(function (localStorageServiceProvider) {
  localStorageServiceProvider
    .setStorageCookie(45, '<path>');
});

###setStorageCookieDomain Set the cookie domain, since this runs inside a the config() block, only providers and constants can be injected. As a result, $location service can't be used here, use a hardcoded string or window.location.
No default value

myApp.config(function (localStorageServiceProvider) {
  localStorageServiceProvider
    .setStorageCookieDomain('<domain>');
});

For local testing (when you are testing on localhost) set the domain to an empty string ''. Setting the domain to 'localhost' will not work on all browsers (eg. Chrome) since some browsers only allow you to set domain cookies for registry controlled domains, i.e. something ending in .com or so, but not IPs or intranet hostnames like localhost.

###setNotify Send signals for each of the following actions:
setItem , default: true
removeItem , default: false

myApp.config(function (localStorageServiceProvider) {
  localStorageServiceProvider
    .setNotify(true, true);
});

###Configuration Example Using all together

myApp.config(function (localStorageServiceProvider) {
  localStorageServiceProvider
    .setPrefix('myApp')
    .setStorageType('sessionStorage')
    .setNotify(true, true)
});

##API Documentation ##isSupported Checks if the browser support the current storage type(e.g: localStorage, sessionStorage).
Returns: Boolean

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  if(localStorageService.isSupported) {
    //...
  }
  //...
});

###getStorageType Returns: String

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  var storageType = localStorageService.getStorageType(); //e.g localStorage
  //...
});

###set Directly adds a value to local storage.
If local storage is not supported, use cookies instead.
Returns: Boolean

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  function submit(key, val) {
   return localStorageService.set(key, val);
  }
  //...
});

###get Directly get a value from local storage.
If local storage is not supported, use cookies instead.
Returns: value from local storage

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  function getItem(key) {
   return localStorageService.get(key);
  }
  //...
});

###keys Return array of keys for local storage, ignore keys that not owned.
Returns: value from local storage

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  var lsKeys = localStorageService.keys();
  //...
});

###remove Remove an item from local storage by key.
If local storage is not supported, use cookies instead.
Returns: Boolean

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  function removeItem(key) {
   return localStorageService.remove(key);
  }
  //...
});

###clearAll Remove all data for this app from local storage.
If local storage is not supported, use cookies instead.
Note: Optionally takes a regular expression string and removes matching.
Returns: Boolean

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  function clearNumbers(key) {
   return localStorageService.clearAll(/^\d+$/);
  }
  //...
  function clearAll() {
   return localStorageService.clearAll();
  }
});

###bind Bind $scope key to localStorageService.
Usage: localStorageService.bind(scope, property, value[optional], key[optional])
key: The corresponding key used in local storage
Returns: deregistration function for this listener.

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  localStorageService.set('property', 'oldValue');
  $scope.unbind = localStorageService.bind($scope, 'property');
  
  //Test Changes
  $scope.update = function(val) {
    $scope.property = val;
    $timeout(function() {
      alert("localStorage value: " + localStorageService.get('property'));
    });
  }
  //...
});

<div ng-controller="MainCtrl">
  <p>{{property}}</p>
  <input type="text" ng-model="lsValue"/>
  <button ng-click="update(lsValue)">update</button>
  <button ng-click="unbind()">unbind</button>
</div>

###deriveKey Return the derive key
Returns String

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  localStorageService.set('property', 'oldValue');
  //Test Result
  console.log(localStorageService.deriveKey('property')); // ls.property
  //...
});

###length Return localStorageService.length, ignore keys that not owned.
Returns Number

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  var lsLength = localStorageService.length(); // e.g: 7
  //...
});

##Cookie Deal with browser's cookies directly. ##cookie.isSupported Checks if cookies are enabled in the browser.
Returns: Boolean

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  if(localStorageService.cookie.isSupported) {
    //...
  }
  //...
});

###cookie.set Directly adds a value to cookies.
Note: Typically used as a fallback if local storage is not supported.
Returns: Boolean

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  function submit(key, val) {
   return localStorageService.cookie.set(key, val);
  }
  //...
});

###cookie.get Directly get a value from a cookie.
Returns: value from local storage

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  function getItem(key) {
   return localStorageService.cookie.get(key);
  }
  //...
});

###cookie.remove Remove directly value from a cookie.
Returns: Boolean

myApp.controller('MainCtrl', function($scope, localStorageService) {
  //...
  function removeItem(key) {
