Warn on non-reactive dependencies in computed

[privatenumber]

Please describe what the rule should do: Warn if a computed property references non-reactive VM properties, such as $slots or $refs.

What category should the rule belong to?

• [ ] Enforces code style
• [x] Warns about a potential error
• [ ] Suggests an alternate way of doing something
• [ ] Other (please specify:)

Provide 2-3 code examples that this rule should warn about: I see this mistake frequently, but doesn't actually work because slots aren't reactive.

computed: {
  hasContentSlot() {
    return !!this.$slots.content;
  }
}

Bumping this since it seems like it was missed

Sorry, I missed it. That rule sounds good to me :+1:

+1!

I can't count how many times I had to mention this in code reviews and give practical examples to showcase: in conditional slot rendering context, there might be an illusion of reactivity when the computed value starts truthy.
