Vite.js 应用程序中“main.js”文件的用途是什么？

Question

I am building a Vite.js app and am not sure I understand the purpose of the main.js file.我正在构建一个 Vite.js 应用程序，但不确定我是否理解main.js文件的用途。 I am having a hard time finding a clear explanation of this in the vite docs .我很难在vite docs中找到对此的明确解释。 I found an S/O post with a similar question in regards to a Vue app, but am not sure if the answers apply to Vite as well.我发现了一篇关于 Vue 应用程序的 S/O 帖子，其中包含类似的问题，但不确定答案是否也适用于 Vite。

I am new to working with these frontend build tools, as well as modules in general, and want to make sure I understand what's happening.我是使用这些前端构建工具以及一般模块的新手，并希望确保我了解正在发生的事情。 I know that index.html serves as the entry point to the app during development, but what is the purpose of main.js exactly?我知道index.html在开发过程中作为应用程序的入口点，但是main.js的目的到底是什么？

My file structure is as follows:我的文件结构如下：

├── package.json
├── vite.config.js
├── index.html
├── main.js
├── styles.css
├── pages
│   ├── login
│   │   ├── login.html
│   │   ├── login.js
│   ├── home
│   │   ├── home.html 
│   │   ├── home.js
│   │

In the main.js you create the app instance, configure it and then mount it to a div tag.在main.js ，您创建应用程序实例，对其进行配置，然后将其挂载到div标签。 This is the way forward for any vue3 application and is independent on the bundling tool used (such as vite ).这是任何vue3应用程序的前进方向，并且独立于使用的捆绑工具（例如vite ）。 A typical example for a main.js is as follows: main.js的典型示例如下：

import {createApp} from 'vue'

import store from './store.js'
import router from './routes.js'
import i18n from './i18n.js'
import App from '../components/App.vue'


// mount is the last one ...
const myApp = createApp(App);
myApp.use(store)
    .use(router)
    .use(i18n)
    .mount('#app');

In the index.html you would load this main.js :在index.html ，您将加载此main.js ：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0"/>
    <title>MyApp</title>
    <link rel="icon" href="/favicon.svg" type="image/svg+xml">
    <meta name="theme-color" content="#ffffff">
</head>
<body>
<div id="app"></div>
<script type="module" src="/src/js/main.js"></script>
</body>
</html>
