Next.js Tutorial Medium
Next.js Tutorial Medium What is Next.js? Next.js is a popular React framework used for building server-side rendered (SSR) web applications. It allows developers to create robust applications with features like static site generation (SSG), automatic code splitting, and optimized performance. What is a Framework? A framework is a collection of tools and libraries that provide a foundation for building applications. It sets rules and guidelines to help developers structure their code, promoting best practices. Frameworks often provide built-in features, which means you spend less time on setup and configuration. Example: In Next.js, you don’t have to manually configure routing; it comes built-in. What is a Library? A library is a collection of pre-written code that developers can use to perform specific tasks. Unlike frameworks, libraries don’t dictate the structure of the application. You are free to call libraries as needed without following a particular workflow. Example: React is a library that helps you build user interfaces. You can choose how to use it within your project. Difference Between Framework and Library Inversion of Control: In a framework, the framework calls your code (this is often called the "Hollywood Principle" - "Don't call us, we'll call you"). In a library, you call the library when you need it. Structure vs. Flexibility: Frameworks encourage (and sometimes enforce) a certain structure, while libraries provide more freedom on how to implement functionality. Next.js Tutorial Medium In this Next.js tutorial medium, we'll cover essential concepts and provide examples to help you get started with Next.js easily. This tutorial will walk you through the basic setup, features, and some practical use cases. Getting Started with Next.js To create a new Next.js application, you can use the following command: npx create-next-app@latest my-next-app This command initializes a new Next.js application with all the necessary configurations. Important Features of Next.js In this Next.js tutorial medium, it’s important to highlight some key features: File-Based Routing: Next.js uses a pages directory for routing, making it easy to define routes based on files. // pages/index.js const Home = () => { return Welcome to Next.js!; }; export default Home; Static Site Generation (SSG) and Server-Side Rendering (SSR): You can choose between generating static pages or rendering them on the server. API Routes: Next.js allows the creation of API endpoints within the same application. // pages/api/hello.js export default function handler(req, res) { res.status(200).json({ message: 'Hello from API!' }); } FAQ Q: Is Next.js easy to learn? A: Yes! If you're familiar with React, transitioning to Next.js is straightforward and intuitive. Q: Can I use Next.js without React? A: No, Next.js is built on top of React, so you'll need to know React to effectively use Next.js. Important to Know Automatic Code Splitting: This means that only the necessary code for the page is loaded, improving performance. Image Optimization: Next.js provides automatic image optimization with the next/image component. In summary, this Next.js tutorial medium is meant to give you a solid introduction to Next.js and its features. Understanding the distinction between frameworks and libraries will help you appreciate the structure provided by Next.js as you develop your applications. By following this Next.js tutorial medium, you'll be well on your way to creating modern web applications with efficient and optimized development practices.

What is Next.js?
Next.js is a popular React framework used for building server-side rendered (SSR) web applications. It allows developers to create robust applications with features like static site generation (SSG), automatic code splitting, and optimized performance.
What is a Framework?
A framework is a collection of tools and libraries that provide a foundation for building applications. It sets rules and guidelines to help developers structure their code, promoting best practices. Frameworks often provide built-in features, which means you spend less time on setup and configuration.
Example:
In Next.js, you don’t have to manually configure routing; it comes built-in.

Difference Between Framework and Library
- Inversion of Control: In a framework, the framework calls your code (this is often called the "Hollywood Principle" - "Don't call us, we'll call you"). In a library, you call the library when you need it.
- Structure vs. Flexibility: Frameworks encourage (and sometimes enforce) a certain structure, while libraries provide more freedom on how to implement functionality.
