Common React Patterns

React patterns are reusable solutions to common problems in component design. This lesson covers three essential patterns: Container/Presentational, Compound Components, and Render Props.

Container/Presentational Pattern

This pattern separates data logic (container) from UI rendering (presentational). Presentational components focus on how things look, while container components focus on how things work.

Container/Presentational: Practical Example

Compound Components Pattern

Compound components work together to form a complete UI. They share implicit state and provide a flexible API.

Compound Components: Menu Example

Render Props Pattern

Render props let you share code between components using a prop whose value is a function.

Render Props: Data Fetching Example

Key Takeaways

1. Container/Presentational - Separate data logic from UI rendering for cleaner code
2. Compound Components - Build related components that work together implicitly
3. Render Props - Share logic between components using functions as props
4. Choose wisely - Each pattern solves different problems; pick the right one
5. Composability - All patterns emphasize building from smaller, reusable pieces
