Quasar CLI makes it incredibly simple to develop or build the final distributables from your source code.
$ quasar dev -m pwa # ..or the longer form: $ quasar dev --mode pwa
Do not run Lighthouse on your development build because at this stage the code is intentionally not optimized and contains embedded source maps (among many other things).
Building for Production
$ quasar build -m pwa # ..or the longer form: $ quasar build --mode pwa
