Modern React Patterns

React has matured dramatically. The patterns that defined great React code in 2019 are not the same patterns that define great React code today. Understanding the shift helps you write components that are easier to test, reason about, and scale.

From Class to Function — and Beyond

The move to hooks was just the beginning. Today, the most impactful shift is thinking in terms of composability over inheritance and data flow over shared state. Components that do one thing well and receive everything they need as props are easier to reuse — and easier to delete when requirements change.

Server Components Change the Mental Model

React Server Components fundamentally separate concerns. If a component doesn't need interactivity, it shouldn't be shipped to the browser. This is not just a performance optimization — it's a new way of thinking about where logic lives.

"The best component is the one that doesn't exist on the client unless it absolutely has to."

Composition over Configuration

Prefer compound component patterns over deeply nested prop trees. When a component accepts fifteen props, it's usually doing too much. Split it. Let the parent own the structure.

Conclusion

Great React code in 2026 means embracing the server/client boundary, keeping components small and composable, and trusting the framework to handle what it handles best.
