The project is hosted on GitHuband the annotated source code is available, as well as an online test suitean example applicationbackbone.js, backbone.js, a list of tutorials and a long list of real-world projects that use Backbone, backbone.js. Backbone is available backbone.js use under the MIT software license. You can report bugs and discuss features backbone.js the GitHub issues pageor add pages to the wiki. Backbone is an open-source component of DocumentCloud.

It is a lightweight library for structuring JavaScript code. If you are not familiar with MVC, it is basically an architecture pattern for implementing user interfaces. It separates the application into three kinds of components:. The intention is to promote separation of concerns which results in better structured and more maintainable application. And to be more accurate it is not even a framework it is just a library that you can use anywhere you want. It is used for developing single-page applications.

You can read the entire file with care in less than a couple of hours. Due to its size, Backbone. This front-end-oriented JavaScript library helps you add interactivity, such as event handling, to static HTML pages in a scalable fashion. Unlike other JavaScript libraries, such as Vue. Even though Backbone. For example, you can create, read, update and delete records from a database. This means JavaScript projects can become unreadable and messy pretty quickly. This means you will unlikely benefit from using a library like Backbone. When you build a complex interface in JavaScript without a library like Backbone. This is because this particular JavaScript library comes from web developers trying to solve structural problems in bigger JavaScript codebases at scale. This makes JavaScript-heavy code projects well organized and easier to maintain. Also, you can couple Backbone. Because of these main features, you can also consider Backbone. Expert Contributors. Software Engineering Perspectives.

Backbone Views can now also take an attributes parameter.

TL;DR: BackboneJS is a JavaScript library that provides models with key-value bindings and custom events, views with declarative event handling, and collections with an abundant API of enumerable functions. BackboneJS gives your web applications structure. In this tutorial, I'll show you how to build a web application with BackboneJS and add authentication to it. Check out the repo to get the code. It is an open source component of DocumentCloud. It was initially released in

It makes programmers to plan out single-page applications. It is built on the MVC approach, which abstracts data into models and DOM into views before connecting the two using events. It provides structure to the application by providing the model with key-value binding and custom events, collections with a rich API of enumerate functions, views with declarative event handling, and connecting it all to your existing API over a RESTful JSON interface. It is designed for developing a single-page web application and for keeping various parts of web applications synchronized. Backbone was created by Jeremy Ashkenas. Here are some of the reasons why you might choose to use Backbone. Skip to content. Change Language.

Routes are one of the most important aspects of any single page application. Routes allow you to intercept browser address changes and act upon them accordingly. In this series of articles, we will explore the core syntax and features that allow you to build-out routing for your single page application. Extending classes is an important topic to quickly review. In Backbone. Extending the Router class allows you to leverage all of the existing functionality while adding more of your own. In this case, our class does not do too much, so we have a bit more work to do. In example 1B, notice that an object is being passed to the extend method.

With Backbone. If defined, you can pass raw attributes objects and arrays and options to add , create , and reset , and the attributes will be converted into a model of the proper type using the provided options, if any. This makes JavaScript-heavy code projects well organized and easier to maintain. Whenever a model or collection begins a sync with the server, a "request" event is emitted. The workspace relies on Backbone. Explore offer now. If the model does not yet have an id , it is considered to be new. It makes heavy use of Backbone. Like Article Like. If the callback argument is omitted router[name] will be used instead. Utility — Backbone. Others still prefer the evented approach, and always fire events instead of calling methods directly. It can be as simple as a string error message to be displayed, or a complete error object that describes the error programmatically. Events is a module that can be mixed in to any object, giving the object the ability to bind and trigger custom named events. If you're directly communicating with a backend CouchDB, MongoDB that uses a different unique key, you may set a Model's idAttribute to transparently map from that key to id.

You can read the entire file with care in less than a couple of hours.

Backbone routes are now able to load empty URL fragments. By default returns the value of the given idAttribute within the attrs , or failing that, id. Contribute your expertise and make a difference in the GeeksforGeeks portal. Simply create a new Collection with the url of your resource endpoint:. Equivalent to instantiating a model with a hash of attributes, saving the model to the server, and adding the model to the set after being successfully created. All of the appropriate "add" , "remove" , and "change" events are fired as this happens, with a single "update" event at the end. Backbone Views can now also take an attributes parameter. CloudApp is simple file and link sharing for the Mac. Client ids are handy when the model has not yet been saved to the server, and does not yet have its eventual true id , but already needs to be visible in the UI. If the callback argument is omitted router[name] will be used instead. If an events hash is not passed directly, uses this.
