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.
