story.js enables web developers to use client-side storages in a simple and consistent way. 
It includes abstraction layer on top of Web Storage API, IndexedDB API, Cookies API and In-Memory storage.
You can use a very easy to learn API in order to master the library. 

Some code examples:
In order to use a storage in story.js you first retrieve it from the story object. For example, here is an example of retrieving the localStorage abstraction:
var storage = story.storage(story.StorageTypes.LOCAL_STORAGE);

After you have the storage object you can use one of the following functions: get, getAll, contain, add, update, remove, and clear. 
Every operation exposes a deferred object that can get a success and error callback.
For example, the following code shows how to use the localStorage abstraction with some API calls:
var storage = story.storage(story.StorageTypes.LOCAL_STORAGE);
storage.add("key", "value").then(function (data) {
    console.log(data);
}, function (error) {
    console.log(error);});
storage.get("key").then(function (data) {
    console.log(data);
}, function (error) {
    console.log(error);
});
storage.contains("key").then(function (data) {
    console.log(data);
}, function (error) {
    console.log(error);
});
storage.update("key", "value1").then(function (data) {
    console.log(data);
}, function (error) {
    console.log(error);
});
storage.remove("key").then(function (data) {
    console.log(data);
}, function (error) {
    console.log(error);
});
storage.contains("key").then(function (data) {
    console.log(data);
}, function (error) {
    console.log(error);
});
storage.clear().then(function (data) {
    console.log(data);
}, function (error) {
    console.log(error);
});

story.js also includes a query object that exposes a query language that resembles LINQ. 
The query language implementation include functions such as where, forEach, first, last and etc.
The query object is exposed as a plugin to the story.js library.
For example, the following code shows how to use the query object:
ar storage = story.storage(story.StorageTypes.IN_MEMORY);
storage.getAll().then(function (data) {
    var items = storage.query.from(data).where(function (item) {
        return item.key === "key2";
    }).forEach(function (item) {
        console.log(item.key + ' ' + item.value);
    });
}, function (error) {
    console.log(error);
});
