My Understanding of NextJs (till now)

An Overview of Features, Routing, and Best Practices for Building Modern Web Applications.

What is Next.js?

Next.js is a React-based framework that simplifies web development with features like Server-Side Rendering (SSR), API routing, and easy file-based routing.

Key Features:

1. Server-Side Rendering (SSR): Improves performance and SEO by rendering pages on the server.
2. Easy Routing: Automatically maps files in the app directory to URLs (e.g., app/about/page.js → /about).
3. Built-In API Support: Create API endpoints directly in your project.

Rendering Techniques:

• Server Components: Rendered on the server for static content.
• Client Components: Rendered in the browser for dynamic, interactive content.

API Routing:

• Create RESTful endpoints in the api folder.
• Supports all HTTP methods (GET, POST, etc.) for CRUD operations.

Dynamic Routes:

• Use [param].js or [...params].js to handle dynamic URLs (e.g., /posts/[id] → /posts/1).

Layouts & Metadata:

• Shared layouts across pages with customizable templates.
• Dynamic metadata for SEO and user experience.

Database Integration:

Works seamlessly with databases like Supabase, MongoDB, and PostgreSQL.

Example:

Static Route:

export default function About() {
  return <h1>About Page</h1>;
}

Accessible at /about.

Why Next.js?

Next.js combines React’s flexibility with server-side capabilities, making it ideal for modern, scalable web applications.
