πŸ”¬ Technical Details

The Versioning

For every release, it will release two versions of this package. The 3.x.x is used for Vue 3 and the 2.x.x is used for Vue 2. We use the major version number to distinguish the different target versions will the minor and patch numbers are shared in both packages.

Different between 3.x and 2.x

For 3.x build, we use the API from @vue/runtime-dom, and for 2.x, it's @vue/composition-api. All the functions exported in this package behaves the same.

// 3.x build
import { ref } from '@vue/runtime-dom'

// 2.x build
import { ref } from '@vue/composition-api'
