```ts title="modern.config.ts"
import { docTools, defineConfig } from '@modern-js/doc-tools';

export default defineConfig({
  doc: {
    base: '/bar/',
  },
  plugins: [docTools()],
});
```

## title

export default defineConfig({
  doc: {
    title: 'My Site',
  },
  plugins: [docTools()],
});
```

```ts title="modern.config.ts"

  },
  plugins: [docTools()],
});
```

  },
  plugins: [docTools()],
});
```

The framework will find your icon in the `public` directory, you can also set it to a CDN address.

Of course you can set different logos for dark/light mode:

```ts title="modern.config.ts"
import { docTools, defineConfig } from '@modern-js/doc-tools';

export default defineConfig({
  doc: {
    logo: {
      dark: '/logo-dark.png',

```

## mediumZoom

- Type: `boolean` | `{ selector?: string }`
- Default: `true`

Whether to enable the image zoom function. It is enabled by default, you can disable it by setting `mediumZoom` to `false`.

> The bottom layer is implemented using the [medium-zoom](https://github.com/francoischalifour/medium-zoom) library.

Example usage:

```ts title="modern.config.ts"
import { docTools, defineConfig } from '@modern-js/doc-tools';

export default defineConfig({
  doc: {
    // Turn off image zoom
    mediumZoom: false,
    // Configure the CSS selector to customize the picture to be zoomed, the default is '.modern-doc img'
    mediumZoom: {
      selector: '.modern-doc img',
    },
  },
  plugins: [docTools()],
});
```

## search

- Type: `{ searchHooks: string }`

You can add search runtime hooks logic through the `searchHooks` parameter, for example:

```ts title="modern.config.ts"
import { docTools, defineConfig } from '@modern-js/doc-tools';
import path from 'path';

export default defineConfig({
  doc: {
    search: {
      searchHooks: path.join(__dirname, 'searchHooks.ts'),
    },
  },
  plugins: [docTools()],
});
```

In `searchHooks.ts`, you need to export the `onSearch` function, which will be called every time a search is performed. The input parameter is the search keyword, and you can customize the search interception logic here, for example:

```ts title="searchHooks.ts"
// Supports async function
export async function onSearch(query: string) {
  // Execute custom logic, such as logging reporting
  console.log(query);
}
```

## globalUIComponents

You can register global UI components through the `globalUIComponents` parameter, for example:

```ts title="modern.config.ts"
import { docTools, defineConfig } from '@modern-js/doc-tools';
import path from 'path';

export default defineConfig({
  doc: {
    globalUIComponents: [path.join(__dirname, 'components', 'MyComponent.tsx')],
  },
  plugins: [docTools()],
});
```

import GlobalUIComponents from '../../fragments/global-ui-components.mdx';
