Halo Bestie — Backend

Fastify.js REST API serving both mobile apps and the internal control center.

See root CLAUDE.md for full project context and architectural decisions.

Stack

  • Runtime: Node.js + Fastify.js
  • Database: PostgreSQL via GCP Cloud SQL
  • Auth: Firebase Auth JWT verification (no session, stateless)
  • Payment: Xendit
  • Infra: GCP Cloud Run

Two Listeners

Public  (0.0.0.0:3000)   → client_app + mitra_app routes
Internal (private IP:3001) → control_center routes only

Internal listener must never be exposed to the public internet.

Route Namespacing

/api/client/...    → client app routes
/api/mitra/...     → mitra app routes
/api/shared/...    → shared routes (e.g. auth, lookup)
/internal/...      → control center routes (internal listener only)

Auth Flow

  1. Firebase Auth issues JWT token on mobile/web
  2. Client sends JWT in Authorization: Bearer <token> header
  3. Fastify verifies token using Firebase Admin SDK on every request
  4. User record fetched from PostgreSQL by Firebase UID

Key Conventions

  • All routes must be authenticated unless explicitly marked public
  • Internal routes have an additional role check (role: admin)
  • Use Fastify plugins for shared middleware (auth, error handling, logging)
  • Business logic lives in services/ — never directly in route handlers
