Reusable Component Patterns

Introduction

Component-Driven Development (CDD) emphasizes the creation of reusable components to enhance productivity and maintainability. Reusable component patterns are strategies that enable developers to build components that can be effectively reused across different applications or projects.

Key Concepts

Types of Reusable Component Patterns

• **Container/Presentational Pattern**: Separates logic (containers) from UI (presentational) components.
• **Higher-Order Components (HOCs)**: Functions that take a component and return a new component with enhanced capabilities.
• **Render Props**: A technique for sharing code between components using a prop that is a function.
• **Hooks**: Functions that let you “hook into” React state and lifecycle features from function components.

Example of Container/Presentational Pattern

            // Container Component
            const UserContainer = () => {
                const [users, setUsers] = useState([]);
                
                useEffect(() => {
                    fetchUsers().then(setUsers);
                }, []);

                return ;
            };

            // Presentational Component
            const UserList = ({ users }) => (
                

                    {users.map(user => 
{user.name}
)}
                
            );
            

Best Practices for Reusable Components

1. Ensure components are stateless whenever possible.
2. Use prop validation to enforce correct usage.
3. Document components using Storybook or similar tools.
4. Keep components small and focused to enhance reusability.
5. Use theme and style props for consistent design.
