What is actually happening?

Type error is happening

@webfansplz I edited type code with your pull request and nothing changed. The problem is here I think.

I don't have a good knowledge about typing types but if I change it to this, I don't get any type error in component file but in type file.

Hi @kadiryazici,Maybe you just forgot to return it when you invoked it

import { defineComponent } from 'vue';


const Component = defineComponent({
   emits: {
      something: (value: string) => true
   }
});

const OtherComponent = defineComponent({
   render() {
      return (
         <Component
            onSomething={() => {
               console.log('yeah');
               return true  // return true
            }}
         />
      );
   }
});

export default OtherComponent

@webfansplz it is not the return type of emit, it is just validator. I return true from validator because I don't need validaton. Vscode type checking is enough for me.

Emit handler should return any or void always.

@kadiryazici You are right, I have mentioned PR to fix this
