Beginner · 1 — Foundations · ~12 min read · Module 2: Layouts & Styling

Introduction

This lesson is part of the beginner section. We explain Navigation and Linking slowly, with examples you can copy and run. If something is unclear, read it twice — that is how everyone learns. next/link prefetches routes and navigates without full page reload. useRouter from next/navigation programmatically pushes URLs in Client Components. Students click between catalog, course, and profile constantly. Full reloads feel slow; Link makes LearnHub feel like an app.

Navigation and Linking appears in almost every LearnHub page you will build. Once it clicks, data fetching and auth become much easier.

When will you use this?

You use layouts and styling in every page you build from your first screen to production.

  • Course catalogs, lesson sidebars, and instructor dashboards all use layouts and shared navigation.
  • When a student opens a lesson page, nested layouts keep the header and progress bar consistent.

Real-world: ShopNest storefront

The E-commerce team building ShopNest storefront uses Navigation and Linking to move between catalog, lesson, and profile without full page reloads. customers and admins never see the TypeScript files — they just get a fast, reliable product pages, cart, and checkout flow.

Production-style code

import Link from 'next/link';

export default function CoursesPage() {
  return (
    <nav>
      <Link href="/">Home</Link>
      <Link href="/courses/nextjs-fundamentals">Next.js course</Link>
      <Link href="/dashboard">My learning</Link>
    </nav>
  );
}

What happens in production: In ShopNest storefront, getting Navigation and Linking right means customers and admins trust the product pages, cart, and checkout flow every day.

Lesson example (start here)

Copy this smaller example first. Once it works, compare it with the real-world code above.

import Link from 'next/link';

export default function CoursesPage() {
  return (
    <nav>
      <Link href="/">Home</Link>
      <Link href="/courses/nextjs-fundamentals">Next.js course</Link>
      <Link href="/dashboard">My learning</Link>
    </nav>
  );
}

Line-by-line walkthrough

CodeWhat it means
import Link from 'next/link';Imports Link — client-side navigation without full page reload.
export default function CoursesPage() {Default export — the main page or component this file provides to Next.js.
return (Returns JSX — what the user sees in the browser.
<nav>Part of the Navigation and Linking example — read it together with the lines before and after.
<Link href="/">Home</Link>Next.js Link — navigates between routes with prefetching.
<Link href="/courses/nextjs-fundamentals">Next.js course</Link>Next.js Link — navigates between routes with prefetching.
<Link href="/dashboard">My learning</Link>Next.js Link — navigates between routes with prefetching.
</nav>Part of the Navigation and Linking example — read it together with the lines before and after.
);Part of the Navigation and Linking example — read it together with the lines before and after.
}Closes a block started by { above.

How it works (big picture)

Do this on your computer

  1. Replace internal links with Link
  2. Hover links in dev — notice prefetch in Network tab
  3. Add active link styling with usePathname in a Client nav component
  4. Use router.push in a Client form after login success
  5. Read the real-world section and name which part of LearnHub uses this topic.
  6. Run the example locally with npm run dev and confirm the same behavior.
  7. Change one value in the example (route, text, or course id) and predict what will happen before you save.

Experiments — try changing this

  • Change a string or route in the example and save — watch the browser update.
  • Break the code on purpose (remove a bracket), read the error overlay, then fix it.
  • Change the href path and confirm navigation still works.

Remember

Link = fast internal navigation. useRouter for imperative redirects. External links use plain .

Common questions

Link for clicks; router.push after form actions or timers.

How long should I spend on Navigation and Linking?

Until you can explain it in your own words and run the example without looking at the answer. Beginners often need 30–60 minutes per new concept; setup lessons may take one afternoon.

What if I get stuck on Navigation and Linking?

Re-read the line-by-line walkthrough, check the terminal and browser overlay for errors, and compare your code character-by-character with the example. Search the exact error text — someone else had it too.

Where is Navigation and Linking used in real jobs?

See the real-world section above — the same pattern appears in LMS, e-commerce, SaaS, and dashboards. Interviewers ask you to explain it using one concrete example.
