Migration to vue3

[koooge]

Hi there, I have some vue2 with @vue/cli projects and considering migrating to vue3 recently. It's really tough and needs to solve a complex dependency domino.
I expected @vue/compat or vue-demi become a great help for my shared libraries. but it didn't work because they have similar limitations like VNode. According to them, vue 3.1 seems to have high compatibility with vue2. But unfortunately, @vue/cli v5 dropped support for vue 3.1 #6808.

I'm wondering if I should make my libs vue2/3 compatible or not. Or should I replace it with vite first? Do you have any good practices or recommendations?

Actually, the pr you linked is not very relevant to what you are describing

I'm already using Vue CLI 5 to build Vue3 and all you need to do is

1. use vue-demi in your shared libraries
2. Remove vue@2 and vue-template-compiler
3. Install vue@3 and @vue/compiler-sfc (eg. @vue/[email protected])
4. Modify the code , write in a way that Vue3 support

This is a tedious and time-consuming task, but it can be finished
