This is highly experimental version with a lot of benefits to make DX even better out of the box!
I only recommend this for JS-projects, not tested in TS, in TS you can probably stay with Volar.
Out of the box experience (not configurable yet!)
Class links / references always work (even without scope attribute) #1038
(beta) Support for Vue@2 options API without defineComponent or configuring jsconfig. And yes it is much better and stable than builtin defineComponent shim support. Even with Vue 2.7! However I know edge-cases where it still fails.
Adds () for methods in completions
Tries to load webpack aliases automatically
Vuex v3 support!
Add more settings / switches to disable features
Return back completions within mixins (mixins itself are supported!)
