🔐 SvelteKit Secure Dev Server #

It not at all difficult to spin up a SvelteKit secure dev server for your app. The SvelteKit command line interface (CLI) will generate a self-signed SSL certificate for you instantly. This lets you access your site via an HTTPS connection as you develop and test it. Although not necessary for many applications, you might be working with something like FIDO U2F multifactor authentication (MFA). In this case it is necessary, even during development, to be running an HTTPS site. Fear not though! This short video takes you through the steps needed to get your HTTPS SvelteKit dev running. You'll be off to the races in no time!

Vite recommend you create your own certificates. You might use openssl or makecert to do this. As a temporary fix, you might consider installing the @vitejs/plugin-basic-ssl Vite plugin:

    
import { sveltekit } from '@sveltejs/kit/vite';
import basicSsl from '@vitejs/plugin-basic-ssl';
 
/** @type {import('vite').UserConfig} */
const config = {
  plugins: [basicSsl(), sveltekit()]
};
 
export default config;
