I'm setting up a local development environment for a Node.js web application that relies on PostgreSQL and Redis. Can you help me write the Dockerfile and docker-compose.yml? I need hot reloading working on my local machine while making sure local dependencies don't get overwritten, and the database should be properly initialized and health-checked before the application starts. Please provide the file structures and configuration blocks for both.

适用于容器化开发的 Docker 和 Docker Compose 最佳实践。
# docker-compose.yml
services:
app:
build:
context: .
target: dev # Use dev stage of multi-stage Dockerfile
ports:
- "3000:3000"
volumes:
- .:/app # Bind mount for hot reload
- /app/node_modules # Anonymous volume -- preserves container deps
environment:
- DATABASE_URL=postgres://postgres:postgres@db:5432/app_dev
- REDIS_URL=redis://redis:6379/0
- NODE_ENV=development
depends_on:
db:
condition: service_healthy

condition: service_started
command: npm run dev
