Introduction
This is advanced material: Sitemap and Robots. It is what teams use on live products. Read the example carefully and try changing one line at a time to see what happens. Sitemap and Robots is advanced App Router routing — groups, parallel routes, intercepting, or edge cases. Complex LearnHub UX (modals, split panels) uses these patterns when basic routes are not enough.
Advanced routing is optional on day one. Read this so you recognize the tools when LearnHub needs modals or parallel panels.
When will you use this?
Use advanced routing when one URL needs multiple panels, modals, or loading states.
- Parallel routes show a video player and notes panel on the same lesson URL.
- Intercepting routes open a course preview modal without leaving the catalog page.
Real-world: Freshdesk-style support portal
The Customer support team building Freshdesk-style support portal uses Sitemap and Robots to apply Sitemap and Robots when building ticket queue and reply interface. support agents never see the TypeScript files — they just get a fast, reliable ticket queue and reply interface.
Production-style code
// app/example/[id]/page.tsx
export default async function Page({ params }: { params: Promise<{ id: string }> }) {
const { id } = await params;
return <p>Sitemap and Robots: {id}</p>;
}
What happens in production: In Freshdesk-style support portal, getting Sitemap and Robots right means support agents trust the ticket queue and reply interface every day.
Lesson example (start here)
Copy this smaller example first. Once it works, compare it with the real-world code above.
// app/example/[id]/page.tsx
export default async function Page({ params }: { params: Promise<{ id: string }> }) {
const { id } = await params;
return <p>Sitemap and Robots: {id}</p>;
}
Line-by-line walkthrough
| Code | What it means |
|---|---|
// app/example/[id]/page.tsx | Comment — notes for humans; the compiler ignores it. |
export default async function Page({ params }: { params: Promise<{ id: string }> }) { | Default export — the main page or component this file provides to Next.js. |
const { id } = await params; | Part of the Sitemap and Robots example — read it together with the lines before and after. |
return <p>Sitemap and Robots: {id}</p>; | Returns JSX — what the user sees in the browser. |
} | Closes a block started by { above. |
How it works (big picture)
- Study the example line by line.
- Each part connects to Sitemap and Robots.
- Edit one line, save, run npm run dev, and see what changes.
Do this on your computer
- Read when to use this vs simpler routing.
- Try the minimal example in a branch.
- Document one LearnHub screen that would need it.
- Read the real-world section and name which part of LearnHub uses this topic.
- Run the example locally with npm run dev and confirm the same behavior.
- 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 API URL or course id and see how the page data changes.
- Use npm run dev while editing Sitemap and Robots — the page hot-reloads on save.
Remember
You learned what Sitemap and Robots is and when to use it in LearnHub. Practice by changing the example yourself. Use the Next link when you can explain it in your own words.
Common questions
What is Sitemap and Robots?
Sitemap and Robots is explained in the introduction above — read it in plain language first.
How long should I spend on Sitemap and Robots?
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 Sitemap and Robots?
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 Sitemap and Robots 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.
