Components in NextJS
🚀 Components in Next.js
In Next.js, components are reusable UI elements built using React. They help in organizing the UI, improving code maintainability, and enhancing performance.
📌 1. Types of Components in Next.js
Next.js supports two types of components:
✅ Functional Components (Standard React components)
✅ Server Components (Faster, used in Next.js App Router)
📌 2. Functional Components (Client-Side)
Functional components are the most common type in Next.js. They can be stateful or stateless.
🔹 Example: Basic Component
<Button>Styled Button<ThemeContext.Provider <ThemeProvider> <Component {...pageProps} /> </ThemeProvider> );}
✅ Great for managing dark mode, authentication, global settings
📌 10. Component Best Practices
✅ Keep components small and reusable
✅ Use Server Components for faster rendering
✅ Use Context API or Zustand for state management
✅ Optimize performance with lazy loading (dynamic()
)
🚀 Summary
Component Type | Use Case | Example |
---|---|---|
Functional Components | Standard UI elements | <Button text="Click Me" /> |
Stateful Components | Interactive UI (e.g., counters) | useState() |
Server Components | Server-side data fetching | async function ServerComponent() |
Layout Components | Header, Footer, Sidebar | <Layout>{children}</Layout> |
Dynamic Components | Lazy-loaded heavy components | dynamic(() => import('./HeavyComponent')) |
Context API | Global state (e.g., theme, auth) | useContext(ThemeContext) |
