Most frontend tutorials today push you toward React or Vue.
So naturally, most developers start there.
But if you’ve ever worked on data-heavy apps (dashboards, admin panels, enterprise tools), you’ll eventually hit this problem:
You’re not just building features — you’re managing a stack.
- UI library
- state management
- grid library
- charting tools
- form handling
- performance optimizations
At some point, it becomes more about integration than development.
A Different Approach: Sencha Ext JS
When I tried Sencha Ext JS, the first thing that stood out was:
- It’s not a library-first ecosystem.
- It’s a complete framework.
Instead of assembling tools, you get:
- 140+ pre-built UI components (grids, charts, forms)
- structured architecture (MVC / MVVM)
- built-in data handling (stores)
- integrated theming and tooling
Getting Started Is Surprisingly Fast
You can generate a working app with:
- npm install -g @sencha/ext-gen
- ext-gen app -a -t moderndesktop -n MyApp
- cd my-app
You instantly get:
- a working UI
- layout system
- grid component
- project structure
This is very different from starting with React, where you configure most things manually.
The Biggest Mental Shift
The hardest part isn’t syntax.
It’s how you think about the app.
With Ext JS, you’re expected to think in:
- components
- layouts
- data stores
- structured architecture
Instead of:
- manual state wiring
- scattered UI logic
At first, it feels heavy.
But as complexity grows, it starts to make sense.
Data Handling Feels Different
Instead of managing arrays or state manually:
store.insert(0, record);
This:
updates the UI automatically
keeps data in sync
avoids unnecessary re-renders
For data-heavy apps, this is a big advantage.
Trade-offs (Honest Take)
- What Feels Hard
- steeper learning curve
- more structure upfront
- less flexibility compared to React
- What Feels Better Over Time
- fewer dependencies
- consistent UI across the app
- easier to scale large projects
- less integration overhead
When This Approach Makes Sense
Ext JS feels like the right choice when:
you’re building dashboards
working with large datasets
creating internal tools
building long-term enterprise apps
Final Thought
Most modern stacks optimize for:
flexibility
Ext JS optimizes for:
structure and scalability
Neither is “better” universally.
But once your app grows…
structure starts to matter more than flexibility.
