Nowadays, development frameworks have become very popular. They provide a lot of in-built libraries, which helps cut down on development time. Thus, you can save the effort and time spent on coding by incorporating frameworks into your projects.
JavaScript web frameworks can improve the efficiency and readability of the code based on how the application is designed.
For example, Sencha Ext JS has earned a good reputation among developers for its ease of use and high-quality implementations. Therefore, it can be a great place to start if you’re new to using frameworks for application development.
Is there a Modular Approach to Development?
Ext JS provides a large number of UI components. You can construct visually appealing web applications that direct your customers to their desired location. You may concentrate on polishing features at a time by breaking down the project into segments. Next, you can put those small chunks together.
Even though one or more features fail, it won’t affect the general stability of the app. Therefore, you can fix the issue without disrupting the app users.
You can significantly improve the success rate of your application by using a modular development technique. Ext JS provides various components focused on multiple utilities, ensuring you can always find what you need.
All components have been meticulously built, allowing you to confidently integrate ExtJS into your application.
What are Practical Data Handling Skills?
So, creating data-intensive applications will allow you to reach a wider audience. ExtJS has components to deal with data, whether to display or analyze it. You may construct dashboards by storing data entries in the grid component and creating attractive visuals.
Does it Support Pre-Built Components?
Pre-built components have become an essential feature of a framework as they reduce development time by reusing the existing standard components.
Ext JS provides a comprehensive set of robust, pre-built components, plug-ins, and tools for creating compelling enterprise-grade apps.
Furthermore, this framework makes creating enterprise-level applications simple and efficient with more than 140 UI components (such as grids, trees, pivot grids, lists, toolbars, forms, menus, and more) that work together seamlessly.
Can the JavaScript Framework Provide Event Libraries?
The event library is a short library that addresses some of the most prevalent issues in event-driven programming. Its thoughtful design allows for future extensions to meet the needs of advanced users.
Ext.util.Observable is a mix-in that defines events in Ext JS. You can subscribe the components that need to receive circumstances to those events using one of the following techniques:
- By using the method on()
- By calling the method addListener()
- Declaratively
JavaScript supports event bubbling. An event bubbling method in Ext JS allows components like Ext.util to dispatch events. You can see it bubbling up through all the enclosing containers.
Moreover, this method indicates that you can manage the events of a component at the container level.
Subscribing to and managing several similar events in one place might be helpful. You can use the enableBubble() function to enable bubbling for specific events.
Does it Support Concurrency?
Concurrency refers to the ability to run many programs or applications simultaneously. For instance, Ext.util.TaskRunner allows you to perform one or more tasks asynchronously.
Ext.TaskManager is a singleton that you can use in most cases. Additionally, you can establish distinct TaskRunner instances to start and stop different tasks.
How Does the JavaScript Framework Handle Views?
Ext JS handles views using the Sencha Architect. Sencha Architect lets you quickly combine application user interface functionalities for desktop and mobile devices.
You may combine a UI utilizing Architect views capabilities with no or little expertise of Sencha frameworks or JavaScript underpinning those views.
This ability makes the Architect ideal for the swift development of visible components of the application. It also implies that design teams can concentrate on the human involvement of the application while others on the team can work on the rest of the program.
Data architects can establish an application’s data side using models and stores. Meanwhile, developers can focus on designing controllers to execute business requirements and the application logic.
You can drag the view components such as containers, forms, grids, and charts into the Project Inspector, view them on Canvas or given layouts, and configure their properties through Config. You can even add your JavaScript to the mix.
Architect creates the code for the project’s current state each time you build it. You can also create your custom view components and export them so that other programmers can use them in their projects.
How does the JavaScript Framework Support Visualization?
Any application must be capable of providing data clearly and appealingly. D3 is a widespread option for data visualization. The new D3 package makes integrating D3 into your Ext JS application easier.
It is included in the packages folder with your Ext JS Premium purchase. Furthermore, you must replicate this packages directory to the root packages directory of the ext folder.
Does it allow Creating Plug-Ins?
A plug-in is a piece of software that enhances the functionality of an existing application by integrating additional capabilities. Ext JS uses Ext. plugin.Abstract as the base class to extend all the plug-ins. This class defines the core API of plug-ins as utilized by components by defining the following methods:
- init – The host component invokes the plug-in initialization function during the component’s initialization. The component is the only parameter passed here. Bidirectional linkages between the plug-in and its host Component must be established using subclasses.
- destroy – The host component calls the cleanup method once the component is destroyed. This method breaks the links between the plug-in and the component and liberates any allocated resources.
How Good is it?
In conclusion, Sencha ExtJS is the best JavaScript web framework available today. In short, it has many excellent features and functionalities. It enables you to design nearly identical applications to what is in your mind.
The best part is that you won’t have to sacrifice the efficiency or aesthetic appeal of the app when using Sencha ExtJS. Because the output will always be powerful and visually attractive.
