Creating next link component

Basic Syntax:

In Next.js, crafting links is a straightforward process, and it starts with the fundamental syntax of the `Link` component. Rather than relying on traditional anchor tags, Next.js employs a specialized `Link` component that seamlessly handles the routing aspects. The basic syntax is designed to align with the React paradigm, maintaining a clean and intuitive structure.

import Link from 'next/link';

const Navigation = () => {

  return (

    <nav>

      {/* Basic Link */}

      <Link href="/home">

        <a>Home</a>

      </Link>

      {/* Dynamic Route Link */}

      <Link href="/products/[id]" as="/products/1"

        <a>Product 1</a>

      </Link>

    </nav>

  );

};

Required and Optional Props in Next.js Link Component:

Next.js link component enriches the link creation process by introducing required and optional props. The `href` prop is a fundamental requirement, specifying the destination of the link. Additionally, optional props like `as` and `replace` offer further customization. The `as` prop allows for providing a human-readable URL, enhancing accessibility, while the `replace` prop allows for navigating without adding a new entry to the history stack.

<Link href="/products/[id]" as="/products/1" replace>

  <a>Product 1</a>

</Link>

This flexibility empowers developers to tailor links based on specific scenarios, ensuring adaptability and efficiency in creating a dynamic and responsive navigation structure for Next.js applications.

Exploring Next.js Link Component Prop Types

Props in Next.js Link component

In Next.js, the `Link` component provides a range of props to tailor link behavior according to specific requirements. These props enhance navigation customization and empower developers with flexible solutions. Let’s delve into the required and optional link component props, exploring their use cases through examples.

Required Prop:

1. href:

The cornerstone of a Next.js link, the `href` prop specifies the destination URL. It is a mandatory prop and defines where the link will navigate upon interaction.

   <Link href="/home">

     <a>Home</a>

   </Link>

Optional Props:

1. as:

The `as` prop allows for a more readable URL while maintaining the original URL structure for routing. This is useful in scenarios where you want to present cleaner, user-friendly URLs.

Use Case: Imagine you have a product detail page with dynamic routes like /products/[id]. Using the as prop, you can present a cleaner and more readable URL to users while maintaining the original routing structure.

      <Link href="/products/[id]" as="/products/1">

     <a>Product 1</a>

   </Link>

2. passHref:

The `passHref` prop ensures that the `href` prop is passed down to the underlying `a` tag. It is useful when you need to apply additional styling or attributes to the anchor tag.

Use Case: When you want to apply custom styling or additional attributes to the anchor (a) tag, you can use the passHref prop to pass down the href prop to the underlying a tag.

  <Link href="/about" passHref>

     <a className="custom-link">About</a>

   </Link>

3. prefetch:

The `prefetch` prop, when set to `true`, prefetches the linked page in the background during idle time. This can significantly improve the user experience by reducing the delay when navigating to the linked page.

Use Case: Consider a navigation menu where users frequently navigate to the “Contact” page. Using the prefetch prop can preload the “Contact” page during idle time, reducing the loading delay when users click on the link.

   <Link href="/contact" prefetch>

     <a>Contact</a>

   </Link>

4. replace:

The `replace` prop, when set to `true`, replaces the current entry in the history stack. This can be useful when you want to navigate without creating a new history entry.

Use Case: In a situation where you want to navigate to a new page without creating a new entry in the browser’s history stack, the replace prop can be beneficial.

  <Link href="/services" replace>

     <a>Services (replacing current entry)</a>

   </Link>

5. scroll:

The `scroll` prop, when set to `false`, disables the automatic scroll to the anchor point when navigating. It can be handy in scenarios where you want to control the scroll behavior manually.

Use Case: When implementing a smooth scrolling effect on your page, you might want to disable the automatic scroll behavior when users navigate to an anchor point within the page.

   <Link href="/faq" scroll={false}>

     <a>FAQ (without scrolling)</a>

   </Link>

6. locale:

The `locale` prop allows you to set a specific locale for the linked page. This is beneficial for applications that support multiple languages, ensuring a seamless language transition.

Use Case: In a multilingual application, you may have different versions of a page for different locales. The locale prop allows you to set the specific locale for the linked page.

   <Link href="/en/about" locale="en">

     <a>English About</a>

   </Link>

7. shallow:

The `shallow` prop, when set to `true`, enables shallow routing, meaning only the URL is updated without running data fetching methods again. This is useful when you want to change the URL without fully reloading the page.

Use Case: In scenarios where you want to change the URL without fully reloading the page and re-running data fetching methods, the shallow prop with shallow routing is useful.

   <Link href="/news" shallow>

     <a>News (shallow routing)</a>

   </Link>

Understanding these Next.js Link props and their applications equips developers with the tools to create dynamic, efficient, and user-friendly navigation experiences in their web applications. Each prop serves a specific purpose, addressing different aspects of link behavior and customization.

Disabling Scroll to the top using Next link component

In a web application, smooth navigation is often key to providing an optimal user experience. Next.js Links come with built-in support for scroll behavior, ensuring a seamless transition between pages. However, there are cases where you might want to disable the default behavior of scrolling to the top when navigating between pages. This can be achieved easily with the `scroll` prop in Next.js Links.

Let’s take a look at an example:

// pages/index.js

import React from 'react';

import Link from 'next/link';

const Home = () => {

  return (

    <div>

      <h1>Home Page</h1>

      {/* Link to another page with scroll behavior disabled */}

      <Link href="/about" scroll={false}>

        <a>Go to About Page</a>

      </Link>

    </div>

  );

};

export default Home;

In this example, the `scroll={false}` prop is added to the Next.js Link component. This simple addition prevents the default behavior of scrolling to the top when navigating to the linked page. It’s particularly useful when you want to maintain the current scroll position on the page, creating a more fluid and user-friendly navigation experience.
