python3 -m http.server 8080
Or with Docker:
docker compose up --build
Then open http://localhost:8080.
Deploy to AWS, GCP, or Digital Ocean with Defang:
defang compose up
The Compose file uses the x-defang-static-files extension for serving files using CDN instead of compute,
which is a feature currently only avaiable on AWS.
