vue3 vite.config.ts basic configuration

Regarding the problem of blank space when directly entering the dist folder to access index.html after packaging the project vite, I searched a lot online and could not find relevant information to solve it. However, if you use FTP to upload it to the server, you can access it normally, so that's it. No more care. If it is a vue3 project created with vue-cli, it can be accessed normally after packaging.

import { defineConfig } from "vite";
import vue from "@vitejs/plugin-vue";
