The framework

A powerful, versatile way to build enterprise web software.

Ext JS is a JavaScript framework used to build feature rich, cross platform web applications. Developed and maintained by Sencha, it lets teams create complex, data intensive applications with an extensive set of UI components, rich data visualisation options and an architecture that simplifies development.

With a focus on code reusability and maintainability, its integration with other frameworks, smooth data handling and support for responsive design make Ext JS a strong choice for enterprise software and consumer facing applications alike.

mVerve re engineers and updates legacy systems, infusing them with new vitality and capability. Our developers average four plus years with the framework, and our Chief Technology Officer has worked with Ext JS since its first version in 2007. We are equally comfortable across Ext JS, ExtReact and ExtAngular.

FAQ

Frequently asked questions.

Why choose Ext JS for a new application?

Ext JS is strongest where the screen is full of data: grids, pivot tables, charts, tree views and forms that need consistent behaviour across browsers. Its component library and data package remove a large amount of custom work for enterprise tooling.

Do you support older Ext JS versions?

Yes. Our Chief Technology Officer has worked with the framework since its first version in 2007, and the team regularly picks up applications built on earlier releases to stabilise, upgrade or extend them.

Can you migrate our Ext JS app to React or Angular?

We do this often. We map the component inventory, agree a phased plan, and migrate module by module so the business keeps running through the transition rather than waiting for a big bang release.

Do you work with ExtReact and ExtAngular?

Yes. The team is conversant across the Sencha suite, including Ext JS, ExtReact and ExtAngular, so we can recommend the right combination for your existing front end.

Can you add Ext JS developers to our team?

You can engage a full delivery team or add senior Ext JS engineers into your existing sprints through our staff augmentation practice.
