Using Enterprise UI Components Inside React: Does It Actually Work?

React is great for building modern Rapid Application Development Tools.

But it has a limitation:

it doesn’t provide complex components out-of-the-box

So developers end up:

• adding grid libraries
• integrating charting tools
• managing state manually
• The Idea Behind React + Ext JS Instead of building everything manually:

use React for app structure
use Ext JS for UI + data-heavy components

This is exactly what Senchs Ext JS Reactor enables

How It Works

• React manages the application
• Ext JS renders complex components
• minimal DOM updates via React virtual DOM

best of both worlds

What You Get

1. Full Ext JS Component Access

• grids
• trees
• pivot tables
• charts
• directly inside React

1. Same Performance as Native Ext JS

No difference in behavior or rendering

components work exactly the same

1. Flexible Architecture

• use React components
• or Ext JS class system
• or mix both
• Optimized Builds

Webpack plugin:

• includes only used components

• supports code splitting
  Limitations

• no server-side rendering

• requires proper setup

• learning curve for Ext JS patterns

• Why This Matters (Enterprise Use Case)
  React alone:

flexible
but requires integration

Ext JS:

structured
built for data-heavy apps

Together:
flexibility + structure

Final Thought

React solves UI composition.

Ext JS solves complex UI systems.

combining them solves both
