[Question] In the future and Object slot typing be supported by this plugin

[louiss0]

🧐 Problem Description

In Vue you are able to inject slots by using this syntax

<HelloWorld>
      { {
          default(props:Record<string, unknown>) {

            return props? props.value : "No props"

          }
        }
      }
 </HelloWorld>

But when I give types for slots I get no error regarding whether or not I'm typing the wrong one or not.

type Slots = SlotsType< { default(props: Record<string, unknown>): JSX.Element }>
export default defineComponent((props: { msg: string, value: number, }, ctx: SetupContext<null, Slots>) => {

 return <> {ctx.slots.default() } </>

}

@louiss0, it is much easier to use v-slots directive, if you want strong typing.

Examples: https://github.com/funny-family/vue3-ts-playground/blob/master/src/app/components/not-found/not-found.component.tsx#L210 https://github.com/funny-family/vue3-ts-playground/blob/master/src/app/shared/components/text-field/text-field.render.tsx

vue-macros/vue-macros#720 vue-macros support the type hint for v-slots

I need to write an object as the child not use a directive.

<HelloWorld>
      { 
          default(props:Record<string, unknown>) {

            return props? props.value : "No props"

          }
        }

 </HelloWorld>

Because of the child maybe a variable to display string.

const foo = 'hello world'
<HelloWorld>
      { foo }
 </HelloWorld>

Can the plugin be rewritten so that JSX works like React or Solid? I should be able to use an object as a child or the template tag to define slots like in SFC. If I specify types in the function I should be forced to type an object as a child.

[zhiyuanzmj]

Vue Macros have a v-slot directive to define slot just like in vue template, also has type hint. https://vue-macros.dev/features/jsx-directive.html#v-slot

Maybe I should add type hints only if the expression is written as an object.

The plugin needs to be rewritten to support objects as child without using an expression.
