Master Next.js Navigation: A Complete Guide to the Link Component

Hey there! 👋

If you're new to Next.js, you might be wondering about all these different ways to navigate between pages. Don't worry! We'll break it down in simple terms.

What's this Link Component Everyone Talks About? 🤔

Think of the Link component as a supercharged version of the regular HTML link (<a> tag) that you might already know. It's like a regular link, but with superpowers! Here's what makes it special:

• It's Super Fast! ⚡
• When you use Link, Next.js starts loading the next page before you even click it (cool, right?). This is called "prefetching" and it makes your website feel lightning-fast.
• No Page Refresh 🔄
• Unlike regular links, clicking a Link component doesn't reload your entire page. It just updates the content that needs to change.

How to Use It? (It's Easy!) 🎯

Here are some simple examples:

1. Basic Navigation

// Just like a regular link!
<Link href="/about">About Me</Link>
    

2. Going to Dynamic Pages

// For pages like /posts/1, /posts/2, etc.
<Link href={`/posts/${postId}`}>Read Post</Link>
    

3. Adding Query Parameters

// For URLs like /search?query=nextjs
<Link href={{
    pathname: '/search',
    query: { query: 'nextjs' },
}}>
    Search Next.js
</Link>
    

Link vs router.push vs <a>: What's the Difference? 🤨

Link Component

• ✅ Best for normal navigation (like menus, buttons)
• ✅ Great for SEO (search engines love it!)
• ✅ Automatically makes your site faster
• ✅ Perfect for links that users can see and click

router.push

• ✅ Best for programmatic navigation (like after submitting a form)
• ✅ Good for redirects based on certain conditions
• ❌ Not great for SEO if used for main navigation
• Example:

// After user submits a form
const handleSubmit = async (e) => {
    e.preventDefault();
    await saveData();
    router.push('/thank-you');
}
            

Regular <a> tag

• ✅ Use for external links (other websites)
• ❌ Avoid for internal navigation in Next.js
• ❌ Causes full page reloads

Pro Tips for Beginners! 💡

1. Always use Link for internal navigation
2. If you're linking to pages within your own website, Link is your best friend!
3. Use router.push after form submissions
4. When you need to redirect users after they do something (like submitting a form), use router.push
5. Use regular <a> tags for external links
6. When linking to other websites, stick with the regular <a> tag

Common Mistakes to Avoid! 🚫

• Don't use <a> tags for internal navigation
• Don't forget to import the Link component
• Don't mix up href formats (stick to one style)
