npm run dev is a command used to start a development server with hot module replacement (HMR) for the project located at https://github.com/trackjs/javascript-gameshow/. It is defined in the scripts section of the project’s package.json file.
The npm run dev command is equivalent to running preact watch --https --host gameshow.local --port 8443 --key /Users/todd/code/_certs/gameshow.local.key --cert /Users/todd/code/_certs/gameshow.local.crt in the terminal.
