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(...)
export { Bar }
// default export call: ok
export default defineComponent(...)
// default export referencing variable declaration: ok
const Baz = defineComponent(...)
export default Baz

Non-supported patterns

// not using `defineComponent` call
export const Bar = { ... }
// not exported
const Foo = defineComponent(...)
