Tech Stack
- Backend: Fastify.js — single codebase, two listeners
- Public (port 3000) → serves
client_appandmitra_app - Internal (port 3001) → serves
control_centeronly
- Public (port 3000) → serves
- Database: PostgreSQL (GCP Cloud SQL)
- Auth: Firebase Auth — Google/Apple social login + phone OTP (native Flutter UI, no WebView)
- Payment: Xendit
- Mobile: Flutter (iOS + Android)
- Control Center: React + Vite SPA
- Infra: GCP — Cloud Run (backend), Cloud SQL (PostgreSQL), VPC private networking
Key Architectural Decisions
- One backend serves both mobile apps — routes namespaced as
/api/client/,/api/mitra/,/api/shared/ - Control center is internal-only — never expose its API routes to the public internet; protected via Nginx allow/deny + VPN
- Firebase Auth tokens are verified on Fastify via JWT — user data lives in PostgreSQL, linked by Firebase UID
- Horizontal scaling (Cloud Run) handles load — do not split into microservices prematurely
- Real-time features use WebSocket for chat + Valkey pub/sub as backend bus; FCM push for background notifications
- Pairing uses blast-to-all-available-mitras with first-come-first-served acceptance
Current Progress
- Phase 1 (Authentication) — fully scaffolded
- Backend routes, services, DB migration + seed script
- client_app: all auth screens (welcome, display name, register, OTP, force-register)
- mitra_app: OTP-only login
- control_center: email/password login, mitra management, user management, anonymity settings
- Docs:
requirement/phase1-plan.md,requirement/phase1-api-contract.md,requirement/client_app_mockup.html
- Phase 2 (Mitra Online Status & Pairing) — fully scaffolded
- Backend: Valkey pub/sub, mitra online/offline status + heartbeat + auto-offline, pairing service, session management, dashboard stats
- client_app: "Mulai Curhat" CTA, searching/found/no-bestie/session-active screens, PairingBloc
- mitra_app: online/offline toggle, heartbeat + lifecycle handling, incoming request notification, active sessions screen
- control_center: dashboard (auto-refresh), max customers per mitra config, session management + reroute, mitra online logs
- Docs:
requirement/phase2.md,requirement/phase2-plan.md
- Phase 3 (Chat Engine) — fully scaffolded
- Backend: WebSocket plugin, chat message service, session timer (backend-authoritative), extension/closure services, FCM push notifications, pricing service (mock tiers + free trial)
- client_app: ChatBloc (WebSocket), ChatOpeningBloc (pricing), SessionClosureBloc, chat screen with message status (sent/delivered/read), typing indicator, extension/goodbye flow, chat history + transcript screens, FCM setup
- mitra_app: MitraChatBloc (WebSocket), ExtensionBloc, chat screen, extension accept/reject, goodbye flow, chat history + transcript screens, FCM setup
- control_center: free trial config, extension timeout config, early end toggles (mitra/customer)

Domain Concepts
- Client — end user seeking mental health support
- Mitra — trained mental health professional (partner)
- Sessions are paid; Xendit handles payment and subscription/trial logic
