🚀 Quick Start

Prerequisites

Node.js >= 18.0.0
npm or yarn
Docker (optional, for containerized deployment)

Installation

Option 1: Manual Installation

# Clone the repository
git clone https://github.com/dickyermawan/kilas.git
cd kilas

# Install dependencies
npm install

# Configure environment variables
cp .env.example .env
# Edit .env with your preferred settings

# Start the server
npm start

Option 2: Using Docker Compose (Recommended)

# Clone the repository
git clone https://github.com/dickyermawan/kilas.git
cd kilas

# Create .env file
cp .env.example .env
# Edit .env with your preferred settings

# Start with Docker Compose
docker compose up -d

# View logs
docker compose logs -f

First Steps

Access Dashboard: Open http://localhost:3000/dashboard
Login: Use credentials from .env (default: admin/admin123)
Create Session: Click "New Session" and scan QR code with WhatsApp
Start Using: Your WhatsApp is now connected! 🎉

🐳 Docker Deployment

Option 1: Using Pre-built Image from Docker Hub (Recommended)

The fastest way to deploy Kilas is using the pre-built image from Docker Hub:

1. Create docker-compose.yml:

services:
  kilas:
    image: dickyermawan/kilas:latest
    container_name: kilas-gateway
    restart: unless-stopped
    ports:
      - "3001:3001"
    environment:
      - PORT=3001
      - ADMIN_USERNAME=admin
      - ADMIN_PASSWORD=admin123
      - API_KEY=admin123
      - CORS_ORIGIN=*
    volumes:
      # Named volumes for automatic permission handling
      - sessions_data:/app/sessions
      - media_data:/app/media
      - db_data:/app/data

volumes:
  sessions_data:
    driver: local
  media_data:
    driver: local
  db_data:
    driver: local

2. Start the container:

# Pull and start
docker compose up -d

# View logs
docker compose logs -f

# Check status
docker compose ps

3. Access the dashboard:

Open http://localhost:3001/dashboard in your browser.

Default credentials:

Username: admin
Password: admin123

⚠️ IMPORTANT: Change ADMIN_PASSWORD and API_KEY in docker-compose.yml for production!

Option 2: Build from Source

If you want to build the image yourself:

# Clone the repository
git clone https://github.com/dickyermawan/kilas.git
cd kilas

# Create .env file
cp .env.example .env
# Edit .env with your settings (PORT=3001 by default)

# Build and start
docker compose up -d --build

# View logs
docker compose logs -f

Configuration

All settings are configured via .env file:

# Server Configuration
PORT=3001  # Default port for both host and container

# Admin Credentials
ADMIN_USERNAME=admin
ADMIN_PASSWORD=admin123

# API Authentication
API_KEY=admin123

# CORS Configuration
CORS_ORIGIN=*

To change port: Edit PORT in .env and restart:

docker compose down
docker compose up -d

Data Persistence

Session, media, and database data are stored in named volumes:

sessions_data: WhatsApp session files
media_data: Uploaded media files
db_data: SQLite database (outgoing messages, webhook history, live events)

Benefits:

✅ Automatic permission handling (no manual chown needed)
✅ Data persists across container restarts
✅ Data persists even if container is removed
✅ Works on all platforms (Windows, Linux, Mac)

Data is safe during:

docker compose restart  # ✅ Data preserved
docker compose down && docker compose up -d  # ✅ Data preserved
docker compose pull && docker compose up -d  # ✅ Data preserved

Data will be lost if:

docker compose down -v  # ❌ Removes volumes (don't use -v flag!)
docker volume rm kilas_sessions_data  # ❌ Manually deletes volume

Backup & Restore

Backup sessions:

docker run --rm -v kilas_sessions_data:/data -v $(pwd):/backup alpine tar czf /backup/sessions-backup.tar.gz -C /data .

Restore sessions:

docker run --rm -v kilas_sessions_data:/data -v $(pwd):/backup alpine tar xzf /backup/sessions-backup.tar.gz -C /data

Docker Commands

# Start containers
docker compose up -d

# View logs
docker compose logs -f

# Stop containers
docker compose down

# Restart containers
docker compose restart

# Update to latest image
docker compose pull
docker compose up -d

# Access container shell
docker exec -it kilas-gateway sh

# Remove all data (CAUTION: deletes sessions!)
docker compose down -v
