"Firebase Functions are your backend. Design them like microservices, deploy them like magic."

Purpose

Configure Firebase Extensions: Stripe payments, SendGrid email, image resize, translation, Algolia search. When to use: Backend development within Firebase/Google ecosystem.

1. The Physics

Law of Functions: Each Cloud Function does ONE thing. Single responsibility.
Law of Cold Start: Minimize dependencies. Use lazy imports. Set min instances for critical functions.
Law of Security: Every HTTP function verifies Firebase ID tokens. No public endpoints without auth.

2. The Protocol

Phase 1: Design

Map requirements to Cloud Functions triggers (HTTP, Firestore, Auth, Storage, scheduled).
