HMR Detection

This plugin supports HMR of Vue JSX components. The detection requirements are:

• The component must be exported.
• The component must be declared by calling defineComponent via a root-level statement, either variable declaration or export declaration.

Supported patterns

import { defineComponent } from 'vue'

// named exports w/ variable declaration: ok
export const Foo = defineComponent({})

// named exports referencing variable declaration: ok
const Bar = defineComponent({ render() { return <div>Test</div> }})
export { Bar }

// default export call: ok
export default defineComponent({ render() { return <div>Test</div> }})

// default export referencing variable declaration: ok
const Baz = defineComponent({ render() { return <div>Test</div> }})
export default Baz

Non-supported patterns

// not using `defineComponent` call
export const Bar = { ... }

// not exported
const Foo = defineComponent(...)
