$el is defined at runtime-core/src/componentPublicInstance.ts line 197

[mmis1000]

I think it's indeed any. Or, to make it safer, unknown. Vue 3 didn't require element to meet specified interface because implementation of node operations is specified outside of runtime-core

https://github.com/vuejs/core/blob/main/packages/runtime-dom/src/nodeOps.ts

The $el can be whatever you want if you are in other runtime.

[baiwusanyu-c]

I agree with @mmis1000 , I also think it should be any. You must know that Vue supports custom renderers, which makes the content rendered by components not necessarily standard dom elements

[DellCliff]

Maybe adjust the documentation at https://vuejs.org/api/component-instance.html#el to reflect that? It states that $el is Node | undefined.

[mmis1000]

Wondering if it is possible to left it as a blank interface and argument in runtime-dom.

Like what express.js does

In this way, if you don't have runtime-dom installed. It is {}. Or if you have, it will suddenly be Node
