Bug Type: Build

Environment

Vue Version: 3.2.31
Element Plus Version: 2.0.2
Browser / OS: Any
Build Tool: Vite

Reproduction

N/A

Reproduction Link

Github Repo

Steps to reproduce

To create a simple vue 3 + vite + element plus

npm create vite@latest my-vue-app --template vue

then install element-plus

npm install element-plus@2.0.2

once setup the project. I am explicitly importing each element plus component like

import { ElButton } from 'element-plus/lib/components/button/index';

With this single "ElButton" component import, my bundle size is like 160kb.

But after some research I find that if I change importing the components from '/lib/' folder I change it to '/es/' folder then the bundle size is reduced to 33kb.

Why this is happening ?

What is Expected?

bundle should import only the imported component from element plus.

What is actually happening?

Importing element-plus component explicitly from inside the /lib/ folder is very heavy and importing all code which is not required.

Additional comments

Need some explanation for this behavior of these imports and which is the better way to import the element-plus components.

element-plus

@ryuhangyeong kind of but can you tell me which is preferable way to import, will this "manually-import" reduce the bundle size as same as the "auto import" ?
I need to reduce the bundle size as much as possible, so which one is good ?

@ryuhangyeong and others ! Does this auto import works with vite SSR ?

@ryuhangyeong thanks, for the link, one more doubt. I am facing issue with vite SSR with auto import. Will this plugin works on SSR ?
