Backbone State

State classes for Backbone Models and Collections.

Usage

Storage

Note: Storage class requires a global Promise object to exist, please include a Promise polyfill if necessary. It also uses ES6 classes with class properties feature which may require transpilation

In order to create a new Store extend the Storage class and set the model and collection to the correct classes.

import Storage from 'backbone.storage';
import Book from './model';
import Books from './collection';

class BookStore extends Storage {
  static model = Book
  static collection = Books
};

var bookStore = new BookStore();

find

In order to retrieve a model from the store simply call find() with an id, an object with an id, or a model instance with an id. If the model does not exist in the store, it will be fetched from the server via the model's fetch() method.

bookStore.find(1).then(model => {
  model.get('name'); // >> A Tale of Two Cities
});

You can optionally pass a boolean forceFetch to ensure a call is made to the backend. Default is false.

bookStore.find(1, true);

findAll

To retrieve the entire collection from the store call findAll(). If the collection has not previously been synced it will call the collection's fetch() method.

bookStore.findAll().then(collection => {
  collection.length; // >> 10
});

Allows a object 'options' that will get passed to the collection fetch call.

bookStore.findAll({
  data: { sortBy: 'name' }
}).then(collection => {
  collection.length; // >> 10
});

You can optionally pass a boolean forceFetch to ensure a call is made to the backend. Default is false.

bookStore.findAll({}, true);

save

When you want to save a model back to the server call the save() method with the model you wish to save. If the model did not previously exist in the store it will be inserted.

var book = new Book({ name: 'Lolita' });
bookStore.save(book).then(model => {
  model.id; // >> 11
});

insert

To insert a model into the store without any server interaction use the insert() method.

var book = new Book({ name: 'Invisible Man' });
bookStore.insert(book).then(model => {
  model.get('name'); // >> Invisible Man
});
