React Is Great - But What If You Need Enterprise UI Components?

The UI component library React gives you flexibility.

But it doesn’t give you:

• data grids
• pivot tables
• advanced UI systems

So what happens?

You build or integrate everything manually

The Problem

In real-world apps:

• UI complexity increases
• Data handling gets messy
• performance needs optimization

React alone doesn’t solve this

The Hybrid Approach

Instead of replacing React:

extend it

Using Ext JS Reactor, you can:

Use Sencha Ext JS components inside React
keep React structure intact
avoid rewriting complex UI

What You Actually Get

1. Full Component Access

• grids
• trees
• pivot tables
• charts

Everything works inside React

1. Same Performance as Ext JS

No difference in behavior

Reactor just coordinates between React + Ext JS

1. Optimized Build

Webpack plugin:

includes only used components
supports code splitting

1. Flexible Architecture

You can:

use React components
Use the Ext JS class system
or mix both

Limitations

• no server-side rendering
• requires setup
• depends on the Ext JS ecosystem

Why This Matters

React = flexible UI layer
Ext JS = structured UI + data system

Together:

• faster development
• less integration work
• better scalability

Final Thought

React solves UI composition

Ext JS solves UI complexity

Combining them solves both
