Node.js lets JavaScript developers move beyond the browser to build scalable backend services. Our live course focuses on practical API architecture for real projects & freelancing readiness.

Core Modules

• Platform overview & environment setup
• Asynchronous patterns (callbacks, promises, async/await)
• Express fundamentals & routing structure
• Controllers, middleware & error handling
• REST design principles & status codes
• Basic auth/session & ENV configuration

2. Quiz backend with score endpoints
3. Minimal ecommerce product API
4. Chat style event simulation (intro to websockets concept)

Tooling & AI

Students use Postman, nodemon and linting. AI tools are introduced for scaffolding route handlers and generating test calls—while enforcing manual reasoning for security & logic.

International Delivery

Evening batches in Karachi (GMT+5) plus recorded sessions help overseas Pakistani students & international participants join seamlessly.

Next Step

Graduates can advance into database optimization, authentication depth (JWT/OAuth) or frontend frameworks to build full stack portfolios.
