Ask Sencha AILearn how to build an AI-driven test grading system with Ext JS, Node.js, MySQL, and OpenAI using secure API architecture, deterministic scoring, and human oversight. Automated assessment has become a key capability for modern EdTech platforms, but evaluating open-ended responses differs fundamentally from scoring multiple-choice questions. A multiple-choice response can be evaluated with deterministic logic. […]

Understanding Ext JS Layouts and Containers: An Introduction (Classic vs. Modern)
Building complex, responsive, and data-intensive Web applications requires a solid layout engine. In Ext JS, the layout system is the backbone of your Application UI. It automatically handles component sizing, positioning, component nesting, and dynamic window resizing, eliminating the need for complex, manual CSS calculations. Whether you are starting a new project or migrating between […]

Set up the Ext JS grid in React with ReExt, then add typed columns, store-backed data, inline editing, grouping and summaries. Full code included. The Ext JS grid has handled data-heavy enterprise screens for years: typed columns, store-backed data, inline editing, grouping and summaries are all built in. With ReExt, you can use that same […]

We know that Ext JS is a war tank. When it comes to handling absurd volumes of data and complex front-end architectures, few frameworks come close. However, writing entire themes based on Sass can become rigid compared to the agile standards of today’s ecosystem. The good news? You can combine the robustness of Sencha components […]
No Comments Read moreTesting Ext JS Applications: What Is Actually Worth Automating
Ask a team with a ten-year-old Ext JS application how much of it is covered by automated tests and the answer is usually a polite laugh. The reasons are understandable: our components are heavy, they need a DOM, they talk to servers, and the framework’s lifecycle can feel opaque. But the real problem is usually […]

In an enterprise Ext JS application, the layout system decides how fast screens render, how well they adapt to different devices, and how easy the codebase is to maintain. Get layouts right and the rest of the UI falls into place. Get them wrong and you end up with deep, sluggish DOM trees and brittle […]
No Comments Read moreFrom JavaScript Library to React: Bringing Ext JS into Modern Front Ends
Many of today’s most important business applications started life in the era of the JavaScript library: when teams picked jQuery for the DOM, YUI or Dojo for widgets, and Ext JS for rich, desktop-like interfaces in the browser. Those applications still run trading desks, hospitals, logistics networks and finance departments. Their front ends, though, now […]
No Comments Read morePerformance Tuning Large Grids and Stores in Ext JS
Grids are where enterprise Ext JS applications live, and they are also where performance problems show up first. A screen that felt instant with 200 rows becomes sluggish with 20,000, and users blame the framework. In practice, the slowdown almost always comes from a handful of avoidable patterns: loading too much data, doing too much […]
No Comments Read moreTaming a Large Ext JS Codebase: Structure, Naming, and Boundaries That Last
Every Ext JS application starts tidy. Five years and forty screens later, you have a util folder nobody dares touch, three grids that are 90% identical, and a build that only one person understands. None of this is Ext JS’s fault. It comes from a few early decisions about structure that were never revisited. This […]
