-# JWT Authentication API Documentation
-
-This document describes how to use the JWT authentication system implemented in this API service.
-
-## Overview
-
-The API provides JWT-based authentication with the following features:
-- User login with username/password
-- JWT token generation
-- Token validation middleware
-- Protected routes
-- User registration
-
-## Endpoints
-
-### Public Endpoints (No Authentication Required)
-
-#### POST /api/v1/auth/login
-Login with username and password to receive a JWT token.
-
-**Request Body:**
-```json
-{
-  "username": "admin",
-  "password": "password"
-}
-```
-
-**Response:**
-```json
-{
-  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
-  "token_type": "Bearer",
-  "expires_in": 3600
-}
-```
-
-#### POST /api/v1/auth/register
-Register a new user account.
-
-**Request Body:**
-```json
-{
-  "username": "newuser",
-  "email": "user@example.com",
-  "password": "securepassword",
-  "role": "user"
-}
-```
-
-**Response:**
-```json
-{
-  "message": "user registered successfully"
-}
-```
-
-### Protected Endpoints (Authentication Required)
-
-All protected endpoints require a valid JWT token in the Authorization header:
-```
-Authorization: Bearer <your-jwt-token>
-```
-
-#### GET /api/v1/auth/me
-Get information about the currently authenticated user.
-
-**Headers:**
-```
-Authorization: Bearer <your-jwt-token>
-```
-
-**Response:**
-```json
-{
-  "id": "1",
-  "username": "admin",
-  "email": "admin@example.com",
-  "role": "admin"
-}
-```
-
-## Demo Users
-
-The system comes with pre-configured demo users:
-
-| Username | Password | Role  |
-|----------|----------|-------|
-| admin    | password | admin |
-| user     | password | user  |
-
-## Using the JWT Token
-
-Once you receive a JWT token from the login endpoint, include it in the Authorization header for all protected endpoints:
-
-```bash
-curl -X GET http://localhost:8080/api/v1/products \
-  -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
-```
-
-## Token Expiration
-
-JWT tokens expire after 1 hour. When a token expires, you'll need to login again to get a new token.
-
-## Environment Variables
-
-To configure JWT authentication, you can set these environment variables:
-
-```bash
-# JWT Secret (change this in production)
-JWT_SECRET=your-secret-key-change-this-in-production
-```
-
-## Testing the Authentication
-
-### 1. Login with demo user
-```bash
-curl -X POST http://localhost:8080/api/v1/auth/login \
-  -H "Content-Type: application/json" \
-  -d '{"username":"admin","password":"password"}'
-```
-
-### 2. Use the token to access protected endpoints
-```bash
-# Get user info
-curl -X GET http://localhost:8080/api/v1/auth/me \
-  -H "Authorization: Bearer <your-token>"
-
-# Get products
-curl -X GET http://localhost:8080/api/v1/products \
-  -H "Authorization: Bearer <your-token>"
-```
-
-## Error Handling
-
-The API returns appropriate HTTP status codes:
-- `200 OK` - Successful request
-- `201 Created` - Resource created successfully
-- `400 Bad Request` - Invalid request data
-- `401 Unauthorized` - Invalid or missing token
-- `500 Internal Server Error` - Server error

+
+### Cara Cepat
+```bash
+# Windows
+tools/generate.bat product get post put delete
+
+# Linux/Mac
+./tools/generate.sh product get post put delete
+
+# Atau langsung dengan Go
+go run tools/generate-handler.go product get post

+### Generate Handler Gagal
+- Pastikan di root project
+- Cek file `internal/routes/v1/routes.go` ada
+- Pastikan permission write
 
-## 🤝 Contributing
+### Database Connection Error
+- Cek PostgreSQL running
+- Verifikasi .env configuration
+- Gunakan `make docker-run` untuk setup otomatis
 
-1. Fork the repository
-2. Create your feature branch (`git checkout -b feature/amazing-feature`)
-3. Commit your changes (`git commit -m 'Add some amazing feature'`)
-4. Push to the branch (`git push origin feature/amazing-feature`)
-5. Open a Pull Request
+### Token Invalid
+- Login ulang untuk dapat token baru

-# Handler Generator CLI Tool
-
-CLI tool untuk generate handler baru secara otomatis dengan swagger documentation.
-
-## Cara Penggunaan
-
-### Windows
-```bash
-# Buka terminal di folder tools
-generate.bat <nama-handler> [methods]
-
-# Contoh:
-generate.bat user get post
-generate.bat product get post put delete
-```
-
-### Linux/Mac
-```bash
-# Buka terminal di folder tools
-./generate.sh <nama-handler> [methods]
-
-# Contoh:
-./generate.sh user get post
-./generate.sh product get post put delete
-```
-
-### Langsung dengan Go
-```bash
-# Dari root project
-go run tools/generate-handler.go <nama-handler> [methods]
-
-# Contoh:
-go run tools/generate-handler.go user get post put delete
-go run tools/generate-handler.go product get post
-go run tools/ generate-handler.go order get post put delete stats
-```
-
-## Method yang Tersedia
-- `get` - GET endpoint untuk list data
-- `post` - POST endpoint untuk create data
-- `put` - PUT endpoint untuk update data
-- `delete` - DELETE endpoint untuk delete data
-
-## File yang Dibuat Otomatis
-
-1. **Handler**: `internal/handlers/<nama>/<nama>.go`
-2. **Models**: `internal/models/<nama>/<nama>.go`
-3. **Routes**: Update otomatis di `internal/routes/v1/routes.go`
-  - **<nama>**: `Nama Directori`
-  - **<nama>.go**: `Nama file class`
-
-## Contoh Penggunaan
-
-### 1. Generate Handler dengan GET dan POST
-```bash
-./generate.sh user get post
-```
-
-### 2. Generate Handler dengan semua method
-```bash
-./generate.sh product get post put delete
-```
-
-### 3. Generate Handler dengan custom method
-```bash
-./generate.sh order get post delete
-```
-
-## Langkah Setelah Generate
-
-1. Jalankan swagger generator:
-```bash
-swag init -g cmd/api/main.go --parseDependency --parseInternal
-```
-
-2. Jalankan aplikasi:
-```bash
-go run cmd/api/main.go
-```
-
-3. Akses swagger UI:
-```
-http://localhost:8080/swagger/index.html
-```
-
-## Struktur File yang Dibuat
-
-### Handler File (`internal/handlers/<nama>/<nama>.go`)
-- Struct handler
-- Constructor function
-- Endpoint methods dengan swagger documentation
-- Error handling
-- Import models dari `api-service/internal/models/<nama>`
-
-### Model File (`internal/models/<nama>/<nama>.go`)
-- Request models
-- Response models
-- Error response models
-- Package name sesuai dengan nama handler
-
-### Routes Update
-- Otomatis menambahkan routes ke `/api/v1/<nama-plural>`
-- Support parameter ID untuk endpoint spesifik
-- Menggunakan componentHandlers untuk handler baru
-
-## Contoh Output
-
-Untuk command: `./generate.sh user get post`
-
-### Handler yang dibuat:
-- `GET /api/v1/users` - List users
-- `GET /api/v1/users/:id` - Get user by ID
-- `POST /api/v1/users` - Create new user
-
-### Struktur Direktori:
-```
-internal/
-├── handlers/
-│   └── user/
-│       └── user.go
-├── models/
-│   └── user/
-│       └── user.go
-```
-
-### Swagger Documentation
-Semua endpoint otomatis memiliki swagger documentation yang bisa diakses di:
-```
-http://localhost:8080/swagger/index.html
-```
-
-## Tips Penggunaan
-
-1. **Nama Handler**: Gunakan nama singular (user, product, order)
-2. **Method**: Pilih method sesuai kebutuhan CRUD
-3. **Custom Fields**: Edit file models yang dibuat untuk menambahkan custom fields
-4. **Service Layer**: Tambahkan service layer untuk business logic yang kompleks
-5. **Repository Layer**: Tambahkan repository layer untuk database operations
-
-## Troubleshooting
-
-### Jika generate gagal:
-- Pastikan berada di root project
-- Pastikan file `internal/routes/v1/routes.go` ada
-- Pastikan permission untuk menulis file
-
-### Jika routes tidak muncul:
-- Cek file `internal/routes/v1/routes.go` untuk duplikasi nama handler
-- Pastikan tidak ada nama handler yang sama dengan yang sudah ada
