Transition to Vite
Before you start working on #1547 (closed), you should consider moving away from vue-cli in favor of vite
It's way faster than vue-cli when it comes to dev and build times. It reduces development server compile times down to miliseconds.
The only 'downside' could be the browser compatibility as vite uses native es modules. Though according to Can I use it's 94.16% (for dynamic import and 94.45% for the modules themselves) of the browsers.
