Either the yarn or the npm package managers can be used to build and test the
application. yarn is preferred since it is more secure, but for now, until older
dependencies have been updated across the stack, only npm may work, so both
options are documented below.
yarn install
yarn run serve
yarn run build
yarn run test
yarn run lint
As above but using npm instead:
npm install
npm run serve
npm run build
npm run test
npm run lint
