Introduction
This article compares knockout.js and backbone.js. We know that knockout and backbone are both JavaScript libraries. But there are some differences in the features and others that will be explained in this article.
Backbone.js:
BackboneJS is a JavaScript library for client-side applications and manages web applications. Backbone.js is a another JavaScript Framework for creating MVC applications. It is gaining attention in the web application community among the other frameworks. It uses the structure provided by JavaScript.
Backbone follows the MV*(Model View) pattern. In other words, the model contains the interactive data and logic of this data. We use the model in backbone to represent the concept of the object using its attributes. The view of the backbone not only works as a view but also works as a controller for connecting the model to the data interaction.
The backbone.js focuses on the following three types of things:
- Client/Server Interaction
- Data Modeling
- Client-side URL mapping
Client/Server Interaction
There are various types of conversations with the backbone View classes that are provided by backbone. But everything depends on you in which way you supply the UserInterface (UI) in the browser.
Data Modeling
Backbone provides the stack for supplying the data to the browser so we should choose backbone.js. Doing all the UI interaction using the backbone is very comfortable, in other words the DOM events are work and callback, supplying and loading the client-side template.
Client-side URL mapping
The other features of backbone is the router support. It provides a very easy way to link up the URL with the client-side template.
Benefits of the backbone:
- Organize the structure of the Web application.
- It provides the Model, DOM and Collection synchronization.
- There are Views, Routers and Model data, all concisely organized.
- Decouples the DOM from the Web page's data.
Knockout.js
Knockout is a JavaScript implementation that helps create rich, responsive displays and editor user interfaces with a clean underlying data mode. It is an open source library implemented entirely in JavaScript. Here is the numbers of sections of UI that are dynamically changed, such as changes depending on the users actions.
Knockout follows the Model View ViewModel (M V VM) pattern, based on MVC and MVP.
Knockout focuses on these two things:
- UI Interaction
- Two Way data binding
UI Interaction
Knockout.Js is a very UI friendly framework. It works automatically with changing your data. When the data changes it automatically updates the UI. And the user interaction will automatically update the data model.
Two-way Data binding
Knockout.JS is the opposite of backbone.JS in the sense that it has no requirements of where the data is coming from. But it does take care of the binding to the DOM and keeps it up to date.
Features of Knockout.JS:
- Declarative binding: It provides a simple way for connecting the parts of the UI with the data model.
- Pure JavaScript library: It can be work with any server and the client-side technology.
- Elegant dependency tracking: It can automatically update the UI depending on the update of the data.
Which framework to use
It is really necessary to know where to spend our time for backbone or knockout. Knockout is very careful about supplying our View and backbone is a separate from the process of the data model. Backbone keeps the data model at the client-side.
The most important thing about both scripts are that these are easily compatible with the JavaScript library.
We can use both knockout and backbone in a web application because they can be integrated without forcing code rewrites of the interfaces and changes.
