## README

# babel-plugin-vue-jsx-hmr [![npm](https://img.shields.io/npm/v/babel-plugin-vue-jsx-hmr)](https://www.npmjs.com/package/babel-plugin-vue-jsx-hmr)

A Babel plugin that adds Vue 3 JSX and TSX HMR support to Webpack and Rspack.

## Usage

### Webpack and Rspack

```bash
npm i -D babel-loader @babel/core @babel/preset-typescript \
  @vue/babel-plugin-jsx babel-plugin-vue-jsx-hmr
```

```js
// webpack.config.cjs or rspack.config.cjs
module.exports = {
    module: {
        rules: [
            {
                test: /\.[jt]sx?$/,
                exclude: /node_modules/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: ['@babel/preset-typescript'],
                        plugins: [
                            '@vue/babel-plugin-jsx',
                            'babel-plugin-vue-jsx-hmr',
                        ],
                    },
                },
            },
        ],
    },
    resolve: {
        extensions: ['.tsx', '.ts', '.jsx', '...'],
    },
    devServer: {
        hot: true,
    },
}
```

The plugin can remain enabled in production; Webpack and Rspack remove its
injected code when HMR is disabled.

### Vite

Use the official
[`@vitejs/plugin-vue-jsx`](https://github.com/vitejs/vite-plugin-vue/tree/main/packages/plugin-vue-jsx)

## HMR detection

HMR injection requires both conditions:

- The component must be exported.
- The component must be declared by calling `defineComponent` in a root-level
  variable or export declaration.

### Supported patterns

```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 <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
```

### Unsupported patterns

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

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