Pyyhkäise näyttääksesi valikon
So far, you have learned how to build user interfaces with HTML, CSS, JavaScript, and React. You can create components, manage state, and handle user interactions.
Now it is time to take the next step.
In real-world projects, applications are not just collections of components. They need routing, data fetching, performance optimization, and a clear structure for scaling and deployment. This is where Next.js comes in.
Next.js is a React framework that provides everything you need to build full web applications. Instead of setting up routing, configuration, and optimization manually, Next.js gives you these features out of the box.
It allows you to focus on building your product while following modern development practices used in production apps.
Example - A Simple Next.js Page
In Next.js, pages are created using files. Here is a basic example:
export default function HomePage() {
return <h1>Welcome to Next.js</h1>;
}
This file automatically becomes a page in your application.
Key Points
- Next.js is built on top of React;
- It adds structure and features for real-world apps;
- You get routing without extra libraries;
- You can run code on the server and the client;
- It helps optimize performance automatically.
Why Developers Use Next.js
Next.js is widely used because it combines simplicity with powerful features:
- You do not need to configure routing manually;
- You can fetch data on the server or client;
- Applications are optimized for performance and SEO;
- It simplifies building and deploying production-ready apps.
Next.js helps you move from building components to building complete applications with a clear structure and modern workflow.
