Serving Static Webpage with Express

Express is a server that handles RESTful endpoints. Svelte is a UI framework for building single page apps. Since Svelte creates static webpages, it can be compiled into an html file and that file can be sent to the client from an Express server. This guide outlines how to do so:

1. Specify the output compile directory in vite.config. {ts, js}. I chose mine as dist. Ex:

import { defineConfig } from 'vite'
import { svelte } from '@sveltejs/vite-plugin-svelte'
