+# 🚀 SeTrip Project Architecture Guide
+
+## 📌 Overview
+
+Dokumen ini menjelaskan standar struktur project untuk aplikasi **SeTrip** menggunakan Next.js (App Router).
+
+Tujuan:
+
+- Menjaga code tetap rapi & scalable
+- Menghindari spaghetti code
+- Memudahkan AI / developer kontribusi
+
+---
+
+# 🧠 Core Principles
+
+1. **Feature-based structure (WAJIB)**
+2. **Separation client vs server logic**
+3. **Colocation (file dekat dengan fitur)**
+4. **No over-engineering (keep it simple)**
+
+---
+
+# 🏗️ Project Structure
+
+```bash
+src/
+├── app/                # Next.js App Router (UI & routing)
+│   ├── (public)/       # halaman publik
+│   ├── (auth)/         # login/register
+│   ├── trips/          # halaman trip
+│   ├── create-trip/
+│   └── profile/
+│
+├── features/           # 🔥 Business logic per domain
+│   ├── auth/
+│   ├── user/
+│   ├── trip/
+│   ├── booking/
+│   └── review/
+│
+├── server/             # 🔒 Backend-only logic
+│   ├── db/
+│   ├── services/
+│   └── repositories/
+│
+├── components/         # reusable UI components
+│   ├── ui/
+│   └── shared/
+│
+├── lib/                # helpers & utilities
+│   ├── prisma.ts
+│   ├── auth.ts
+│   └── utils.ts
+│
+├── hooks/              # custom react hooks
+├── types/              # global types
+└── config/             # config (env, constants)
+```
+
+---
+
+# 📂 Folder Rules
+
+## 1. `/app` (Routing Layer)
+
+Hanya untuk:
+
+- page.tsx
+- layout.tsx
+- UI rendering
+- data fetching ringan
+
+❌ DILARANG:
+
+- business logic
+- query database langsung
+
+---
+
+## 2. `/features` (Domain Layer) 🔥
+
+Setiap fitur punya folder sendiri:
+
+```bash
+features/trip/
+├── components/
+├── services/
+├── hooks/
+├── api/
+└── types.ts
+```
+
+Digunakan untuk:
+
+- business logic
+- validation
+- orchestration
+
+---
+
+## 3. `/server` (Backend Layer)
+
+```bash
+server/
+├── db/
+│   └── prisma.ts
+├── services/
+│   └── trip.service.ts
+└── repositories/
+    └── trip.repo.ts
+```
+
+Digunakan untuk:
+
+- database access
+- heavy logic
+- internal backend
+
+---
+
+## 4. `/components`
+
+```bash
+components/
+├── ui/        # button, input, modal
+└── shared/    # navbar, header
+```
+
+---
+
+## 5. `/lib`
+
+Utility global:
+
+- prisma instance
+- auth helper
+- formatter
+
+---
+
+# 🔄 Data Flow Standard
+
+```text
+UI (app/)
+  ↓
+Feature (features/)
+  ↓
+Service (server/services)
+  ↓
+Repository (server/repositories)
+  ↓
+Database
+```
+
+---
+
+# 🧩 Example Flow (Create Trip)
+
+1. User klik create trip (UI)
+2. Call feature service
+3. Feature validate data
+4. Call server service
+5. Service call repository
+6. Repository insert ke database
+
+---
+
+# ⚠️ Anti-Pattern (DILARANG)
+
+❌ Jangan:
+
+- query Prisma langsung di page.tsx
+- campur UI + logic
+- buat folder controller/service ala backend di Next.js
+- over abstraction di awal
+
+---
+
+# ✅ Best Practice
+
+✔ Gunakan:
+
+- Zod untuk validation
+- Prisma untuk ORM
+- Server Actions / API route secukupnya
+
+✔ Naming:
+
+- `trip.service.ts`
+- `trip.repo.ts`
+- `useTrip.ts`
+
+---
+
+# 🚀 Development Phases
+
+## Phase 1 (MVP)
+
+- Auth
+- Create Trip
+- Join Trip
+
+## Phase 2
+
+- Review
+- Limit & validation
+
+## Phase 3
+
+- Payment
+- Organizer role
+
+---
+
+# 🧠 Final Principle
+
+> Build fast → validate → refactor later
+
+Jangan terlalu fokus ke arsitektur sempurna di awal.
+
+---
+
+# 📌 Notes for AI / Contributors
+
+- Ikuti struktur ini tanpa pengecualian
+- Jangan membuat folder baru tanpa alasan jelas
+- Semua fitur baru harus masuk ke `/features`
+- Semua akses DB harus lewat `/server`
+
