# @rsbuild/plugin-vue2

## Usage

Install:

```bash
npm add @rsbuild/plugin-vue2 -D
```

Add plugin to your `rsbuild.config.ts`:

```ts
// rsbuild.config.ts
import { pluginVue2 } from "@rsbuild/plugin-vue2";

export default {
plugins: [pluginVue2()],
};
```

After registering the plugin, you can import `*.vue` files in your code.

## Options

If you need to customize the compilation behavior of Vue, you can use the following configs.

### vueLoaderOptions

Options passed to `vue-loader`, please refer to the [vue-loader documentation](https://vue-loader.vuejs.org/) for detailed usage.

- **Type:** `VueLoaderOptions`
- **Default:**

```js
const defaultOptions = {
compilerOptions: {
whitespace: "condense",
},
experimentalInlineMatchResource: true,
};
```

- **Example:**

```ts
pluginVue2({
vueLoaderOptions: {
hotReload: false,
},
});
```

> The Vue 2 plugin is using the `vue-loader` v15. Please be aware that there may be configuration differences between v15 and the latest version.

### splitChunks

When [chunkSplit.strategy](/config/performance/chunk-split) set to `split-by-experience`, Rsbuild will automatically split `vue` and `router` related packages into separate chunks by default:

- `lib-vue.js`: includes vue, vue-loader.
- `lib-router.js`: includes vue-router.

This option is used to control this behavior and determine whether the `vue` and `router` related packages need to be split into separate chunks.

- **Type:**

```ts
type SplitVueChunkOptions = {
vue?: boolean;
router?: boolean;
};
```

- **Default:**

```ts
const defaultOptions = {
vue: true,
router: true,
};
```

- **Example:**

```ts
pluginVue({
splitChunks: {
vue: false,
router: false,
},
});
```

## FAQ

### /deep/ selector causes compilation error

`/deep/` is a deprecated usage as of Vue v2.7. Since it is not a valid CSS syntax, CSS compilation tools like Lightning CSS will fail to compile it.

You can use `:deep()` instead. See [Vue - Deep Selectors](https://vuejs.org/api/sfc-css-features.html#deep-selectors) for more details.

```html

.a :deep(.b) {
/* ... */
}

```

> You can also refer to [Vue - RFC 0023](https://github.com/vuejs/rfcs/blob/master/active-rfcs/0023-scoped-styles-changes.md) for more details.
