Top Ext JS Alternatives and Overview

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.
