Introduction to Using App Router in Next.js

Next.js is one of the most popular frameworks for creating web applications. One of the powerful features of this framework is the App Router, which allows developers to implement advanced and customizable routing in their applications. The App Router provides you with the capability to utilize the features of Node.js for managing the server state and client in conjunction with routing. In this article, we aim to explain the complete usage of the App Router and examine its advantages and possibilities.

One of the aspects that distinguishes the App Router from other routing methods is its complete integration with other components of Next.js, such as data fetching, pages, and API routes. This means you can easily create pages and API extensions based on your own requirements.

By utilizing the App Router, managing and maintaining routes in the application becomes significantly easier. This is due to the structured way this tool is designed, and developers can easily create more complex routes. Overall, it can be said that the App Router has a high capability for expansion and flexibility, making it one of the main choices for large applications.

Furthermore, we will closely examine how to configure and use the App Router step by step. This section will include precise descriptions and sample codes that you can implement in your own projects. Stay with us to discover the valuable insights of this section and enhance your skills in developing modern web applications.

import { useRouter } from 'next/router';

const MyComponent = () => {
  const router = useRouter();

  const handleNavigation = () => {
    router.push('/new-page');
  };

  return (
    <div>
      <button onClick={handleNavigation}>Go to New Page</button>
    </div>
  );
};

export default MyComponent;

In line import { useRouter } from 'next/router';, we utilize the useRouter hook, which is part of the next/router library, to gain access to the routing capabilities of the application. In the component MyComponent, by defining const router = useRouter();, we can manage the routing of Next.js applications. The function handleNavigation, defined in the component, utilizes router.push to redirect the user to the new route /new-page. In the render section, when we click on the button, the handleNavigation function is executed, which sends the user to the new page. The component is exported using export default MyComponent; so we can easily use it in other parts of the project.
