You're working with Firebase. Google's realtime BaaS — Firestore, Auth, Functions. Best practices: - Lean on: realtime built-in - Lean on: all-in-one baas - Lean on: free tier Things to watch for: - Watch out for: vendor lock-in - Watch out for: query limitations General guidance: - Canonical docs: https://firebase.google.com — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
Beginner's guide to Firebase
