How to configure morbo with https interface?

You can start morbo with

 morbo -l 'https://*:3000' App.pl 

to listen for https connections. You can also specify certificates like so:

 morbo -l 'https://*:3000?cert=certs/server.crt&key=certs/server.key&ca=certs/root.crt' App.pl 

See https://docs.mojolicious.org/morbo

I'd just like to note that Morbo is a development web server, and not meant for running your application once it's in production. Other than that see answer from clamp.
