Introduction to Navigation in Next.js

Navigation is an essential part of any web application. Next.js simplifies navigation by providing the Link component, which enables you to create links between pages and navigate without full-page reloads. In this tutorial, we'll learn how to add links and navigate in a Next.js application.

Using the Link Component

The Link component is used to create links in Next.js. It provides a declarative way to navigate between pages. Here's an example:

import Link from 'next/link';
<Link href="/about">
    <a>About Us</a>
</Link>
                

In this code, clicking the "About Us" link will take you to the "about" page.

Client-Side Navigation

Next.js handles client-side navigation, so when you use the Link component, the transition between pages is smooth and doesn't involve a full page reload. This provides a faster and more seamless user experience.

Passing Query Parameters

You can pass query parameters to your linked pages by specifying them in the href attribute. For example:

<Link href="/product?id=123">
    <a>Product Details</a>
</Link>
                

In the linked page, you can access the query parameters using the useRouter hook or other methods provided by Next.js.
