# install dependencies
npm install

# build for production with minification
npm run build

# test the production build locally
npm run serve

# deploy production build to Firebase
npm run deploy

# run tests with jest and preact-render-spy
npm run test

NOTE: When running npm run serve, the build/index.html file is removed before serving locally. This is because firebase serve --only hosting,functions command does not appear to respect hosting.ignore array in firebase.json
