}),

Default: 'babel'

Defines how typescript transformation is handled for .tsx files.

'babel' - typescript transformation is handled by @babel/plugin-transform-typescript during babel invocation for JSX transformation.

'built-in' - babel is invoked only for JSX transformation and then typescript transformation is handled by the same toolchain used for .ts files (currently esbuild).

$3

Type: any[]

Default: undefined

Provide additional plugins for babel invocation for JSX transformation.

$3

Type: any

Default: undefined

Defines options for @babel/plugin-transform-typescript plugin.

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 or the name specified in defineComponentName via a root-level statement, either variable declaration or export declaration.

$3

`jsx
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

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

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