ASGI Framework - FastAPI, Starlette, Quart, or any ASGI-compatible framework
Redis (optional) - For production channel layers with cross-process communication

Install Fast Channels using pip:

pip install fast-channels

This installs the core Fast Channels package with in-memory channel layer support, suitable for development and testing.

For production use, install with Redis support:

pip install "fast-channels[redis]"

This includes Redis-backed channel layers for reliable, scalable real-time communication across multiple processes.

For production deployments, you’ll need a Redis server for channel layers:

Using Docker:

# Run Redis in Docker
docker run -d -p 6379:6379 redis:alpine

Using Docker Compose:

# docker-compose.yml
version: '3.8'
services:
  redis:
    image: redis:alpine
    ports:
      - "6379:6379"

System Installation:

# Ubuntu/Debian
sudo apt update && sudo apt install redis-server

# macOS with Homebrew
brew install redis

# Start Redis
redis-server
