Bundle size of Vue Router 4 lib became larger than Vue Router 3 lib

[AlexanderSlesarenko]

Hello everyone,
I moved my project from Vue2 to Vue3 and as you can see from screenshots Vue Router bundle size increased.
Vue3:

Vue2:

Is it correct or may be I do something wrong?
How I use Vue Router:
import { createWebHistory } from 'vue-router'
import { createRouter } from 'vue-router'

If you need any additional details I will provide them.

I think you are not treeshaking your libraries. Maybe not minifying them. You should indeed see a smaller size with Vue Router 4

I looked into bundled code. It's minified and treeshaked.
For example, there is no unused createWebHashHistory, but createWebHistory exists.
