Sencha's JS Days is back, and this year's program has plenty for React developers.
Dates: September 16–17, 2026
Format: Fully virtual, join from anywhere
Cost: Free
Hosted by: Sencha, part of Idera, Inc.
What's In It for React Developers
If you're building React apps for a living, these are the sessions worth blocking on your calendar. The 2026 program focuses on practical topics React developers actually deal with:
- Building AI agents with React and ReExt
- UI design patterns you can apply to real component libraries
- Making React work alongside Ext JS and other frameworks without the headaches
- Case studies from apps shipped to production
- Clean architecture as your React codebase grows
Sessions React Devs Shouldn't Miss
Building AI Agents with JavaScript, React, and ReExt
Speaker: Marc Gusmano, Sales Engineer, Sencha
A hands-on look at how to build AI agents using React and ReExt — practical, not theoretical.
UI Design Best Practices
Speaker: Rafael Méndez, Sencha MVP
Design patterns and component-level decisions that make React UIs feel professional, not just functional.
Recruitment App Case Study
Speaker: César Martell, Software Developer
A real-world walkthrough of a production React app — architecture, trade-offs, and what worked.
Opening Keynote
Speaker: James Cahill, General Manager, Sencha
Sets the tone for both days and where the JavaScript ecosystem is headed.
Plus sessions from Wemerson Januario, Andres Villalba, and more speakers still being announced.
How the Two Days Work
Day One opens with the keynote, followed by 45-minute sessions across multiple tracks.
Day Two focuses on low-code tools, UI design, and React — streamed live with speaker Q&A and open discussion rooms.
