State classes for Backbone Models and Collections.
Note: Storage class requires a global
Promise
object to exist, please include aPromise
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();
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);
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);
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
});
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
});
