什么是angular-storage,A Storage done right for AngularJS

angular-storage介绍、angular-storage使用

A Storage done right for AngularJS.

Key Features

  • Uses localStorage or sessionStorage by default but if it’s not available, it uses ngCookies.
  • Lets you save JS Objects
  • If you save a Number, you get a Number, not a String
  • Uses a caching system so that if you already have a value, it won’t get it from the store again.

Installing it

You have several options: Install with either bower or npm and link to the installed file from html using script tag.

bower install a0-angular-storage
npm install angular-storage

Using it

angular.module('app', ['angular-storage'])
.controller('Controller', function(store) {
  var myObj = {
    name: 'mgonto'
  };

  store.set('obj', myObj);

  var myNewObject = store.get('obj');

  angular.equals(myNewObject, myObj); // return true

  store.remove('obj');

  store.set('number', 2);

  typeof(store.get('number')) === 'number'
});

Namespaced Storages

You can also create namespaced storages if you want

angular.module('app', ['angular-storage'])
.factory('Auth0Store', function(store) {
  return store.getNamespacedStore('auth0');
})
.controller('Controller', function(Auth0Store) {

  var myObj = {
    name: 'mgonto'
  };

  // This will be saved in localStorage as auth0.obj
  Auth0Store.set('obj', myObj);

  // This will look for auth0.obj
  var myNewObject = Auth0Store.get('obj');

  angular.equals(myNewObject, myObj); // return true
});

Changing storage type

angular.module('app', ['angular-storage'])
  .config(function(storeProvider) {
    // Store defaults to localStorage but we can set sessionStorage or cookieStorage.
    storeProvider.setStore('sessionStorage');
  })
  .controller('Controller', function(store) {

  var myObj = {
    name: 'mgonto'
  };

  // This will be saved in sessionStorage as obj
  store.set('obj', myObj);

  // This will look for obj in sessionStorage
  var myNewObject = store.get('obj');

  angular.equals(myNewObject, myObj); // return true
});

API

storeProvider.setStore(storageName)

store.set(name, value)
