# Container Configuration
# Port for the application to listen on inside the Docker container
LISTEN_PORT=8080

# Public URL for the application (as accessed by users through reverse proxy)
# This should NOT include the container port - reverse proxy handles that
PUBLIC_URL=https://bufferbloat.yourdomain.com

# WebRTC UDP Configuration
# Hostname or IP address for direct UDP connections (WebRTC data channels)
# This can be different from the HTTP hostname if UDP traffic bypasses the reverse proxy
WEBRTC_UDP_HOSTNAME=your-server-direct.com
# Alternative: Use direct IP address instead of hostname
# WEBRTC_UDP_IP=192.168.1.100

# Range of UDP ports for WebRTC data channels
# Make sure these ports are open in your firewall and accessible directly
WEBRTC_UDP_PORT_MIN=10000
WEBRTC_UDP_PORT_MAX=10100

# Alternative: Single UDP port (comment out the range above if using this)
# WEBRTC_UDP_PORT=10000

# Application Settings
NODE_ENV=production
LOG_LEVEL=info

# Test Configuration Parameters
# Duration of bufferbloat test in seconds
DEFAULT_TEST_DURATION=30

# Size of test packets in bytes
DEFAULT_PACKET_SIZE=1024

# Rate of test packets per second
DEFAULT_PACKET_RATE=100

# Example configurations for different environments:

# Development (local testing)
# LISTEN_PORT=8080

# WEBRTC_UDP_HOSTNAME=localhost
# WEBRTC_UDP_PORT_MIN=10000

# LOG_LEVEL=debug

# Production (behind nginx reverse proxy with separate UDP endpoint)
# LISTEN_PORT=8080
# PUBLIC_URL=https://bufferbloat.example.com           # Users access this (reverse proxy forwards to container:8080)
# WEBRTC_UDP_HOSTNAME=direct.example.com              # Direct to server (no proxy)
# WEBRTC_UDP_PORT_MIN=10000

# Production with IP address for UDP (common setup)

# WEBRTC_UDP_IP=203.0.113.10                          # Direct server IP
