    Building Responsive Web Applications With Sencha Ext JS and ASP.NET API

    Jan 31, 2026
    I have worked on multiple software projects where we have used Sencha Ext Js as a core JavaScript framework. We used Microsoft ASP.net Api as backend services and Ext Js in terms of JavaScript framework. It is very easy to develop highly responsive desktop like looking web applications very easily. Its UI components are very refined and rich.

Reviewer Insights for: Ext JS

Ext JS Likes & Dislikes

Like

The most beautiful part of Ext Js is that it provides completely rich UI components such as charts, grids, trees, forms, and more. An application built with this framework looks exactly like a desktop application, is very responsive, fast, and is the best in terms of end user experience. The most powerful component that I consider is its Grid which has full features like filtering, grouping, sorting, and customization capability.
