Sencha's JS Days is back for 2026 — free, virtual, and this year's program is heavier on the stuff developers are actually dealing with day-to-day.
Dates: September 16–17, 2026

* Cost*: Free

What's New This Year
The 2026 program focuses on topics that weren't front and center in previous editions:
AI-assisted development, done right
A dedicated session on building AI agents with JavaScript, React, and ReExt. Practical patterns for integrating AI into real workflows without losing code quality or oversight.
Cross-framework interoperability
Real coverage of what happens when React sits next to Ext JS or legacy stacks. Practical approaches to reducing friction across mixed codebases.
A production case study
A full walkthrough of a real recruitment app — architecture, trade-offs, what shipped, what didn't. This kind of session is rare at bigger conferences and worth showing up for.
UI design for enterprise apps
Component-level design decisions from a Sencha MVP with years of production experience. Less "trends," more "here's what actually works.
Low-code workflows for JavaScript teams
Day 2 dives into how modern teams are using low-code tools alongside traditional development to ship faster.
