一覽

Firebase is Google's platform for building mobile backends: Realtime Database (sync data across devices in milliseconds), Cloud Functions (serverless compute triggered by data changes), Cloud Storage (store files/images), Hosting (deploy static site/single-page app). No backend engineering required, declare data structure, add security rules, call APIs. Learning: 2-3 weeks for basic CRUD, 6-8 weeks for production systems with complex rules and functions. Practitioners earn 15-20% premium for shipping mobile apps 5x faster. Firebase unblocks indie developers and startups to launch full-featured apps without hiring backend engineers.

什麼是 Firebase Mobile Platform

Firebase is Google's unified platform for building mobile app backends. Instead of writing servers, you use managed services: Firestore (real-time database), Cloud Functions (serverless compute), Cloud Storage (file storage), and Hosting (deployment). Declare data structure, add security rules to control access, and your app works. Firebase handles scaling, redundancy, and security. No backend engineering required. Mobile developers call Firebase APIs directly from their apps. Data syncs in real-time: user edits note on phone, iPad sees change instantly (zero-latency sync via WebSockets).

❓ 常見問題

Should I use Realtime Database or Firestore?
Firestore is the modern choice. Better querying, better scaling, better for complex data. Realtime Database is older but still fast for simple use cases. Use Firestore unless you have low-latency requirements (gaming, real-time chat).
What can Cloud Functions do?
Triggered by database changes: user signs up → send welcome email. Scheduled (cron): daily cleanup. HTTP: handle API requests. Integrate with external services (Stripe, Twilio, Slack).
How do I authenticate API calls from my app to Firebase?
Firebase handles it. Call Firebase API, Firebase checks auth token automatically. No API keys to manage (use security rules instead). Very simple.
What's a security rule and why do I need one?
Security rule: 'User can only read their own data.' Without it, any user can read everyone's data. Rules are the guardrails. Firestore won't let unauthorized reads through.
Can I use Firebase for a web app or only mobile?
Both. Firebase works for iOS, Android, Web (JavaScript). Web apps are often the easiest to ship.
