JS allows websites to render only content that changes without reloading the entire page on every request (e.g., AJAX). Many of the logic/code that used to be on the server-side is now on the client-side. The user doesn’t need to wait between requests and page refreshes. Web applications nowadays require heavy use of JavaScript to generate content on the fly. However, these require extra plugins and are not as ubiquitous as JavaScript. A couple of languages can run in the browsers besides JS, using Web Assembly techniques or using deprecated Java Applets or Flash. However, providing the website with even more responsiveness, speed, and enhanced user interaction requires bringing the page generation closer to the users (in the browser rather than a remote server). That was a considerable improvement, and most of the pages served today use this approach. Later, in web 2.0, developers started using server-side programming languages (like PHP, Ruby, Java, …) to generate HTML pages dynamically based on user input and data stored in a database. In the beginning, web applications were just static HTML pages, which required programmers to change the code (HTML, CSS, JS) to change the content. The web application development process has been evolving over the years. TL DR: You need to use JavaScript heavily in order to make responsive and interactive web applications. Backbone.js for absolute beginners - getting started (part 4: Routers).Backbone.js for absolute beginners - getting started (part 3: CRUD).Backbone.js for absolute beginners - getting started (part 2: Models, Collections and Views).Backbone.js for Absolute Beginners - Getting started (Part 1: Intro) □ you are here.Let’s dive into BackboneJS! And see how this flexible library can bring order to your Javascript! Follow my AngularJS tutorial series for a framework solution. Libraries give you a lot of flexibility, while frameworks have opinionated ways of doing things but can save you from writing boilerplate code. Using a library, YOU are in control, but there is an inversion of control using a framework: the framework calls you. Notice that BackboneJS is not a framework but a library. Var productCollection = is a JavaScript library, among many others, that is gaining special attention in the web development community because of its ease of use and the structure that it provides to JavaScript applications. These are the model sets defined as below: This is the reference to the DOM element and is used to compose the element’s content and render them into DOM at once. One important property of the view is el. The important part of the view is the render method which is actually responsible for presenting the Model data to user using the Templates. jQuery tmpl (outdated), Underscore.js, Moustache.js etc. The data is presented using JavaScript Templating e.g. This contains the logic behind presenting the Model to the user. In real world application development, this comes from external Web/WCF services or WEB API. Model is an important declaration for Data-Driven Web applications. This is defined by extending the Backbone.Model as below: These are used to contain data for the application and logic around this data. There are some important features provided by Backbone as discussed below: This is very important for designing dynamic applications using JavaScript. The advantage of using backbone is that it provides lightweight data structuring mechanism using model and collection and helps to use these in generated Views. Typically, this library is used to build SPA’s. This easily helps to decouple concerns in the application. Using these frameworks, a developer can develop Rich and better UX applications.īackbone.js is a lightweight library for structuring client side code. Thankfully there are several JavaScript client side frameworks available to get this thing done e.g. But one of the important aspects for Web development is to provide a Rich user interface with UX (user experience). Currently there are lots of different frameworks available for developing web applications, most of these are server side frameworks e.g. In the current era of web application development, Single Page Applications (SPAs) are often demanded by customers.
