Welcome to Part 11 of the Ultimate Guide to Server-Side Scripting! In this session, we’ll create and configure an Express app inside a Google Cloud Function — merging the power of Express.js with serverless architecture. This setup allows you to build scalable, event-driven APIs without managing servers while keeping your familiar Node.js + Express workflow.

✅ What You’ll Learn in This Video:
✔️ Setting up an Express instance inside a Cloud Function
✔️ Handling HTTP requests using Express routes (GET, POST, PUT, DELETE)
✔️ Structuring middleware for authentication, validation, and error handling
✔️ Understanding how Cloud Functions manage Express lifecycle
✔️ Testing the deployed Express function via Firebase Emulator or HTTP endpoint

💡 Why This Step Matters:
🔹 Combines the flexibility of Express with the scalability of Google Cloud Functions
🔹 Reduces deployment overhead while maintaining full REST API control
🔹 Enables serverless API endpoints that auto-scale with demand
🔹 Prepares you for integrating authentication, database logic, and API gateways
