JavaScript Web Storage Simpler way of handling Storage


Example

localStorage, sessionStorage are JavaScript Objects and you can treat them as such.
Instead of using Storage Methods like .getItem(), .setItem(), etc… here's a simpler alternative:

// Set
localStorage.greet = "Hi!"; // Same as: window.localStorage.setItem("greet", "Hi!");

// Get
localStorage.greet;         // Same as: window.localStorage.getItem("greet");

// Remove item
delete localStorage.greet;  // Same as: window.localStorage.removeItem("greet");

// Clear storage
localStorage.clear();

Example:

// Store values (Strings, Numbers)
localStorage.hello = "Hello";
localStorage.year  = 2017;    

// Store complex data (Objects, Arrays)
var user = {name:"John", surname:"Doe", books:["A","B"]};
localStorage.user = JSON.stringify( user );

// Important: Numbers are stored as String
console.log( typeof localStorage.year ); // String

// Retrieve values
var someYear = localStorage.year; // "2017"

// Retrieve complex data
var userData = JSON.parse( localStorage.user );
var userName = userData.name; // "John"

// Remove specific data
delete localStorage.year; 

// Clear (delete) all stored data
localStorage.clear();
