## qwikVite

The types for Vite/Rollup don't allow us to be too specific about the return type. The correct return type is `[QwikVitePlugin, VitePlugin<never>]`, and if you search the plugin by name you'll get the `QwikVitePlugin`.

```typescript
export declare function qwikVite(qwikViteOpts?: QwikVitePluginOptions): any;
```

| Parameter | Type | Description |
| --- | --- | --- |
| qwikViteOpts | [QwikVitePluginOptions](#qwikvitepluginoptions) | _(Optional)_ |

**Returns:**

any

## QwikVitePlugin

This is the type of the "pre" Qwik Vite plugin. `qwikVite` actually returns a tuple of two plugins, but after Vite flattens them, you can find the plugin by name.

```typescript
export type QwikVitePlugin = P<QwikVitePluginApi> & {
  name: "vite-plugin-qwik";
};
```
