How do I set up Docker Compose for my React app?

To set up Docker Compose for your React app, you'll need to create a docker-compose.yml file. Do you have a Dockerfile ready?

Yes, I have a Dockerfile. What should I include in the docker-compose.yml?

You should define your services in the docker-compose.yml. For a React app, it might look like this:

version: '3'
services:
  web:
    build: .
    ports:
      - '3000:3000'
    volumes:
      - .:/app
    environment:
      - NODE_ENV=development

What does each part of this configuration do?

The build specifies the context for building the image, ports maps the container port to the host, volumes allows live code updates, and environment sets environment variables.
