Modern applications live in the cloud in the current world, generating large amounts of data to be processed. The data should be presented to the user in an understandable, interactive way and served up in real-time. Modern data-intensive applications need a modern infrastructure to meet those needs. That is why is the most comprehensive JavaScript framework for building data-intensive, cross-platform web and mobile applications for any device. Sencha Ext JS This article will explain why Ext JS is the best choice for developing web applications. #1. Ext JS supports all the modern browsers. A modern browser is any browser that renders a web application using current web standards. You don’t have to write any browser-specific hacks with a modern browser. It should also deliver outstanding performance. Modern browsers supported by Ext JS are: Chrome Firefox IE 11+ Safari 9+ Opera Microsoft Edge #2. Ext JS has Pre-integrated and tested high-performance UI components. As a developer, you need to deliver your web application to different platforms that your users might be on. The challenge is developing a user interface that will work across these platforms while maintaining the right look and feel. Ext JS solves this challenge by including 140+ UI components such as HTML5 calendar, grids, pivot grid, D3 adapter, trees, lists, forms, menus, toolbars, panels, and windows. #3. Ext JS has tools for building robust applications. Ext JS has the necessary tools provided by Sencha to help you build data-intensive applications, including those listed below. Sencha CMD Sencha Cmd is a complete set of life-cycle management tools including scaffolding, code minification, and transpilation from ES6. Other options are dynamic package loading, build generation for PWAs, and more. Sencha Architect Sencha Architect helps you build applications on Ext JS using drag-and-drop features, allowing you to save time by spending less time on manual coding. IDE and Code Editor Plugins These tools integrate Ext JS into your enterprise workflow, enabling code completion, inspection, generation, navigation, refactoring, and more. Inspector Inspector is a debugging tool that provides you with direct access to components, classes, objects, and more for apps built using Ext JS. Sencha Fiddle Sencha Fiddle is a tool that allows you to try Ext JS code in your browser without downloading or installing anything. #4. Ext JS supports MVC architecture. MVC is an architectural pattern consisting of model, view, and controller. The model handles logic, while the view displays the information from the model to the user. The controller controls the data flow into a model object and updates the view whenever data changes. MVC is a pattern used to implement user interfaces, data, and controlling logic in software design. It emphasizes the separation between the software’s business logic and display. This separation provides for a better division of labor and improved maintenance. #5. Ext JS has a ton of resources. Sencha provides you with to help you build web applications using Ext JS. These are huge time savers because they can be beneficial, especially if you get stuck. resources These resources include: Tutorials Webinars Datasheets Whitepapers Documentation #6. Ext JS supports object-oriented programming. Object-oriented programming (OOP) is a computer programming model that facilitates software design around data or objects rather than functions and logic. OOP focuses on the objects developers want to manipulate rather than the logic required to manage them. This programming approach is well suited for large, complex, and actively maintained programs.** ** Additional benefits of OOP include code reusability, scalability, and efficiency. #7. Ext JS has testing tools for your application. When you use Ext JS to build your application, you can test it using Sencha Test. Sencha Test is the complete unit and testing solution for Ext JS. Sencha Test helps developers to: Improve the quality of their applications through end-to-end testing. Leverage unit and functional testing to increase release cycles. Create robust tests by leveraging the deep integration. #8. Ext JS is adaptive. Ext JS includes a layout manager to flexibly organize the content across multiple browsers, devices, and screen sizes. It allows you to control the display of components, even for complex user interfaces. Ext JS also provides a responsive system that allows application components to adapt to device orientation or available browser window size. #9. Ext JS prioritizes accessibility. Ext JS includes features that align with ADA Standards for Accessible Design. In addition, the Ext JS ARIA package allows you to add accessibility support to your applications by providing the tools you need to achieve Section 508 compliance. Using the ARIA, you can create apps that can be used by those who need assistive technologies, for example, screen readers to navigate the web. #10. Ext JS has an advanced data package. Ext JS has a robust data package that decouples the UI components from the data layer. The data package allows client-side data collections using highly functional models that offer features such as sorting and filtering. The data package is protocol-agnostic and can consume data from any back-end source. The data package comes with session-management capabilities that allow several client-side operations, minimizing round trips to the server. Conclusion As you have seen from the reasons above, Ext JS is the best framework to build web applications. This is especially true if you are looking to develop applications with cross-browser functionality. Ext JS will provide you with a rich UI to make that possible. By Bonnie
