When Spring Boot meets React: bridging two worlds

Front-end and back-end are often built by two different mindsets; what makes them click is clear contracts.

# Clear data contracts

Agree on data types and date formats between Spring Boot and React up front to avoid nasty timezone bugs.

# CORS and auth

Configure CORS carefully and use short-lived tokens; handle refresh at the right layer so the experience stays seamless.

• Generate types from the schema when possible
• Standardize errors so the front-end handles them easily
• Log enough to trace across both layers

Smoothness comes from clear communication — between services and between people.
