Top Ext JS Alternatives

Web app development is very important in modern-day internet because of the speed and robustness it offers over native applications. It is lightweight and does almost everything the native app does, without going specifically into device dependent codes. Sencha ExtJS is a web application development framework that provides a better development experience and smoother UI along with some intuitive features like cross-platform command-line tools, compilers, etc.

Integrated tools to develop better apps

ExtJS has over 140+ integrated UI components that help developers to design efficiently without having to leave the IDE. It includes several features like Grid – which handles records and provides functions like sorting and grouping objects and a D3 Adapter – which helps to add Data-Driven Documents packages to the program source code, including treemaps and heatmaps.

The layout feature checks whether all the UI components shown to the end-user is aligned or not according to the screen size. You can export data from Grid and Pivot grids to be used in various applications easily. Integrate analytics functions to apps using the Pivot Grid tool.

Test applications and add accessibility support

Sencha Test is the end-to-end testing feature that is available in the ExtJS framework. It enables the testing of your apps and improving the performance and features. Perform unit testing and functionality analysis on apps to increase productivity and optimize release cycles. Benefit from the integration of the Sencha Test and ExtJS framework to debug and find out issues in apps and fix them quickly.

Add accessibility features faster and make it compliant with Section 508 standards. Using the ExtJS ARIA package, it's possible to add support for assistive technologies like screen readers and text-to-speech engines.

Adaptive design and Data collection

Web apps need to be designed in a way that scales to fit the viewport of the device in which it runs. It should be able to adjust the fonts automatically and display size to match the specifications. The flexible layout manager helps to configure the displaying of data across different web browsers and platforms.

The data package enables the collection of data from the device, which may include file uploads, downloads, and cache. It also has a session management feature to minimize database round-trips and ensure maximum speed.

Command-line tools and UI

It also a command-line tool named ExtGen to facilitate multiple modes for application creation and execution. The lifecycle management feature ensures better minification of code, dynamic loading, and development of Progressive Web Apps.
