How does NextJS App Router work?

User's Answer: (none)

Correct Answer:

NextJS App Router is a powerful routing system that allows you to manage client-side and server-side routing in your Next.js application. Here's how it works:

Client-Side Routing

• NextJS uses the next/link component to handle client-side routing. This component generates an HTML anchor tag with a href attribute that points to the desired route.
• When the user clicks on a link, the browser navigates to the new route, and NextJS handles the routing on the client-side.
• The next/link component also provides a prefetch option, which allows you to prefetch pages in the background, improving page loading times.

Server-Side Routing

• NextJS uses the getStaticProps and getServerSideProps methods to handle server-side routing. These methods allow you to fetch data on the server and pass it to the page component.
• When a user requests a page, NextJS checks if the page is statically generated or needs to be rendered on the server.
• If the page is statically generated, NextJS returns the pre-rendered HTML. If the page needs to be rendered on the server, NextJS runs the getServerSideProps method to fetch data and render the page.

How it all works together

• NextJS App Router uses a combination of client-side and server-side routing to provide a seamless user experience.
• When a user navigates to a new page, NextJS checks if the page is statically generated or needs to be rendered on the server.
• If the page is statically generated, NextJS returns the pre-rendered HTML. If the page needs to be rendered on the server, NextJS runs the getServerSideProps method to fetch data and render the page.
• The next/link component handles client-side routing, allowing users to navigate between pages without a full page reload.

Next.js App Router: A Comprehensive Overview

What is Next.js App Router?

Next.js App Router is a powerful routing system built into Next.js, a popular React-based framework for building server-side rendered (SSR) and statically generated websites and applications. It allows you to define routes for your application and manage client-side and server-side rendering seamlessly.

How Does Next.js App Router Work?

Client-Side Rendering (CSR)

When a user navigates to a route, Next.js App Router uses the getStaticProps method to fetch the necessary data for the route. The data is then passed to the component as props, allowing it to render the necessary content.

Server-Side Rendering (SSR)

When a user navigates to a route, Next.js App Router uses the getServerSideProps method to fetch the necessary data for the route. The data is then passed to the component as props, allowing it to render the necessary content.

Route Matching

Next.js App Router uses a combination of regular expressions and route patterns to match routes. You can define routes using the next/router module, which provides a useRouter hook for client-side rendering and a useServerSideProps hook for server-side rendering.

Route Parameters

Next.js App Router supports route parameters, which allow you to capture dynamic values in your routes. You can access route parameters using the useRouter hook or the useServerSideProps hook.

Linking and Redirecting

Next.js App Router provides a Link component for client-side linking and a useRouter hook for server-side linking. You can also use the useRouter hook to redirect users to a different route.

Code Example

1import { useRouter } from 'next/router';
2
3function MyComponent() {
4  const router = useRouter();
5
6  return (
7    <div>
8      <h1>{router.query.name}</h1>
9      <button onClick={() => router.push('/other-route')}>Go to other route</button>
10    </div>
11  );
12}

1import { useRouter } from 'next/router';
2
3function MyComponent() {
4  const router = useRouter();
5
6  return (
7    <div>
8      <h1>{router.query.name}</h1>
9      <button onClick={() => router.push('/other-route')}>Go to other route</button>
10    </div>
11  );
12}

In this example, the MyComponent component uses the useRouter hook to access the router object, which provides information about the current route. The component also uses the router.push method to redirect the user to a different route when the button is clicked.

Conclusion

Next.js App Router is a powerful and flexible routing system that allows you to define routes for your application and manage client-side and server-side rendering seamlessly. By understanding how Next.js App Router works, you can build robust and scalable applications with ease.
