Using Existing UI Systems Inside React: A Practical Approach

Migrating to React doesn’t always mean starting from scratch.

Many teams already have mature UI systems built with other frameworks. Rewriting everything — especially complex components like data grids, forms, and dashboards — can be time-consuming and risky.

This is where integration approaches come in.

Instead of replacing everything, developers can reuse existing UI components inside a Rapid Application Development Tools. For example, structured component systems like Ext JS can be integrated into React, allowing teams to keep proven, feature-rich components while adopting modern workflows.

This approach offers a few clear benefits:

  • Reduces rewrite effort
  • Preserves tested UI components
  • Speeds up migration timelines
  • Maintains performance for data-heavy features

However, it’s not completely frictionless. Proper state synchronization and component lifecycle handling are important to ensure smooth interaction between systems.

In many real-world cases, combining React with an existing UI system can be more practical than a full rewrite — especially for large, enterprise-scale applications.
