I've seen references to getCurrentInstance() function on some old(?) documents and codes, but cannot find it in the current Vue 3 document.

Is getCurrentInstance() deprecated?

If so, what is the reason? (inject() considered enough?) If not, why can't I find it in the document?

CodePudding user response：

I think the docs for getCurrentInstance() were accidentally removed...

getCurrentInstance() was originally documented in 4-Oct-2020, but that was later removed in 31-Aug-2021 in a major refactoring of the Composition API docs by the creator of Vue (Evan You). It's unclear whether the removal of those docs was intentional because getCurrentInstance() still:

• is widely used in Vue core.

• is not documented as deprecated in code.

• is exported as part of the Advanced API.

I would consider it an undocumented API for the moment. However, it's possible that Evan intended for it to be an internal API only.
