Vitejs is loading the whole bundle size instead of the selected ones

I am using vue 3 with vite. I noticed something strage. Oh vue icons is loading something like 108 MB of bundle size and it takes a lot of time to load even in vitejs. Here's my setup

import { addIcons, OhVueIcon } from 'oh-vue-icons'
import {
  FaFacebookSquare,
  FaInstagram,
  FaLinkedin,
  FaQuora,
  FaTwitter,
  FaYoutube,
} from 'oh-vue-icons/icons'

// register the icons
addIcons(
  FaFacebookSquare,
  FaInstagram,
  FaLinkedin,
  FaQuora,
  FaTwitter,
  FaYoutube
)

const app = createApp(App)
app.component('VIcon', OhVueIcon)
app.mount('#app')

Then in my component:

<VIcon name="fa-facebook-square" />
<VIcon name="fa-youtube" />
<VIcon name="fa-instagram" />
<VIcon name="fa-quora" />
<VIcon name="fa-linkedin" />
<VIcon name="fa-twitter" />

You can see the problem below. I am conditionally controlling these six icons. That's why there are only one or two icons per card.

Why is it loading 108 MB of javascript? That doesn't make any sense. Also I am using vite with vue3. Do I need to add any extra configuration?

Thanks in Advance.

From Vite docs:

Performance: Vite converts ESM dependencies with many internal modules into a single module to improve subsequent page load performance.

Some packages ship their ES modules builds as many separate files importing one another. For example, lodash-es has over 600 internal modules! When we do import { debounce } from 'lodash-es', the browser fires off 600+ HTTP requests at the same time! Even though the server has no problem handling them, the large amount of requests create a network congestion on the browser side, causing the page to load noticeably slower.

By pre-bundling lodash-es into a single module, we now only need one HTTP request instead!

oh-vue-icons/icons contains many files that Vite is pre-bundling at startup.

Since you don't really need the icons to be prebundled, you can opt out of the prebundling with optimizeDeps.exclude:

// vite.config.js
import { defineConfig } from 'vite'

export default defineConfig({
  ⋮
  optimizeDeps: {
    exclude: ['oh-vue-icons/icons']
  }
})
