serve as https

Due to avoid various permissions problems it is often good to develop under https so can we add this feature?

This is cool, but we might also need to register the certs on the local machine.

Is there a way the certs generated can be written to a ./certs folder, from where the developer may opt to install them to their local machine?

Also, the certs could be re-used across multiple Vite projects, and not regenerated on each npm run Vite.

Finally, Vite knows the local network IP addresses on that machine, adding these to the list of altNames on the cert would be useful.

Dev server running at:
  > Network:  https://192.168.2.4:3000/
  > Network:  https://192.168.43.154:3000/
  > Local:    https://localhost:3000/
