Real-world: Practo-style clinic portal

The Healthcare team building Practo-style clinic portal uses Job Portal Project to apply Job Portal Project when building appointment booking and medical records UI. patients and doctors never see the TypeScript files — they just get a fast, reliable appointment booking and medical records UI.

Production-style code

// next.config.ts — security headers snippet
const securityHeaders = [
  { key: 'X-Frame-Options', value: 'DENY' },
  { key: 'X-Content-Type-Options', value: 'nosniff' }
];

What happens in production: In Practo-style clinic portal, getting Job Portal Project right means patients and doctors trust the appointment booking and medical records UI every day.

Lesson example (start here)

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

// next.config.ts — security headers snippet
const securityHeaders = [
  { key: 'X-Frame-Options', value: 'DENY' },
  { key: 'X-Content-Type-Options', value: 'nosniff' }
];

Line-by-line walkthrough

How it works (big picture)

• Study the example line by line.
• Each part connects to Job Portal Project.
• Edit one line, save, run npm run dev, and see what changes.

Do this on your computer

1. Apply one security control from the example.
2. Scan headers with browser devtools or securityheaders.com.
3. Note one threat this lesson mitigates.
4. Read the real-world section and name which part of LearnHub uses this topic.
5. Run the example locally with npm run dev and confirm the same behavior.
6. 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.

Remember

You learned what Job Portal Project 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.
