Vite https on localhost

Easiest way is to use the vite-plugin-mkcert package.

npm i vite-plugin-mkcert -D

vite.config.js

import { defineConfig } from 'vite'
import mkcert from 'vite-plugin-mkcert'

export default defineConfig({
  server: { https: true },
  plugins: [ mkcert() ]
})

When you run the local vite dev server you may be prompted for your password the first time. It will then install a local certificate onto your system and to a number of installed browsers.

Easy!
