Setup:

npm install

Cleanup (remove node modules and /dist):

npm run clean

Run backend and frontend for development (i.e. with full hot reloading):

npm run dev

You can also run the backend and frontend for development separately (in order to differentiate output streams):

npm run backend
npm run frontend

Build files to /dist:

npm run build

Run for production (outputs files in /dist and runs express server to serve them, along with backend):

npm run prod
