I tried the steps again and was able to see all styling. Perhaps you could check if your npm is up to date and other settings are correct. You could also use Chrome Developer Tool to see if there’s any error behind the scene.
Quasar is a front-end framework. What you are looking for or rather where you should be looking is within the API or backend, which Quasar currently doesn’t have. There are two API wrappers in the works. One for a REST API based on FeathersJS and another for a GraphQL API based on Apollo. They should get you a lot closer to what you are looking for.
