#Adding global imports in Starlight

I have seen you answer elsewhere about using the mdx() plugin to automatically add globalImports to every MDX file. I want to do this but I am using Starlight, which installs the MDX integration for me. Is there a way to add globalImports to starlight?

Hi @hasty notch. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Yes, you can add global imports to MDX files in Starlight by configuring the MDX integration that Starlight uses under the hood. Starlight is built on top of Astro and includes the @astrojs/mdx integration by default.

You can customize the MDX configuration by using a Starlight plugin. Here's how to do it:

  1. Create a custom plugin for Starlight that configures the MDX integration:
// starlight-mdx-globals.js
export default {
  name: 'starlight-mdx-globals',
  hooks: {
    'config:setup': ({ updateConfig, config }) => {
      // Get the existing MDX configuration if any
      const existingMdx = config.markdown?.mdx || {};
      
      updateConfig({
        markdown: {
          mdx: {
            ...existingMdx,
            // Add your global imports here
            globalImports: [
              // Example: import a component in all MDX files
              '@components/MyComponent',
            ],
          },
        },
      });
    },
  },
};
  1. Then add this plugin to your Starlight configuration in astro.config.mjs:
import { defineConfig } from 'astro/config';
import starlight from '@astrojs/starlight';
import starlightMdxGlobals from './starlight-mdx-globals.js';

export default defineConfig({
  integrations: [
    starlight({
      title: 'My Docs',
      // Add your custom plugin to Starlight
      plugins: [starlightMdxGlobals],
    }),
  ],
});

This approach leverages Starlight's plugin system, which allows you to customize the configuration while maintaining compatibility with Starlight's built-in features. The plugin API gives you access to update the configuration that Starlight uses internally.

@uncut hearth This didn't seem to work, I am getting messages that my component is not defined.

Let me check the knowledge base for you again. One moment! :books:

I'm sorry to hear that you're experiencing issues with the component not being defined. This is a common problem when working with MDX files in Astro. Let me help you troubleshoot this issue.

When you see "component is not defined" errors in MDX files, there are a few potential causes:

Common MDX Component Issues

  1. Import path issues: The global import path might be incorrect or the component might not be accessible from where MDX is trying to import it.

  2. Missing component export: The component needs to be properly exported from its source file.

  3. MDX configuration: The globalImports might not be correctly applied to the MDX integration.

Troubleshooting Steps

Here are some specific steps to fix the issue:

  1. Check for import errors: Make sure the component path in your globalImports is correct and accessible. Absolute paths with aliases need to be properly configured in your tsconfig.json or jsconfig.json.

    // Use full relative paths from the project root
globalImports: [
  './src/components/MyComponent.astro',
],

  2. Verify component is properly defined: Ensure your component is correctly exported from its file.

  3. Try explicit imports first: Before using global imports, test if you can import the component directly in an MDX file to confirm it works.

    ---
title: Test Page
---
import MyComponent from '../components/MyComponent.astro';

<MyComponent />

  4. Check for common errors: As mentioned in the Astro troubleshooting guide, make sure:

    • Your import has the correct path
    • The import name matches the component name
    • You've included the file extension for non-JS/TS files
#
  1. Verify MDX integration: If you're still having issues, make sure the MDX integration is properly installed. Starlight includes it by default, but you might need to check for any MDX integration errors.

If you're still experiencing issues, could you share:

  1. The exact error message you're seeing
  2. The structure of your component
  3. The path you're using in the globalImports array

This would help me provide more specific guidance for your situation.

Remember that Starlight is built on Astro, so many of the common Astro troubleshooting steps apply here as well.

@uncut hearth The import I've added to globalImports is import { SiBun, SiCloudflareworkers, SiDeno, SiNodedotjs } from '@icons-pack/react-simple-icons'; I have tested this using explicit imports and it works. The error I'm getting is Expected component SiBun to be defined: you likely forgot to import, pass, or provide it. I tried outputting the config object the plugin is modifying and it doesn't have anything about markdown or mdx in it, so I think the config I'm adding is being ignored.

I see the issue now. It looks like there are two problems: the React component import isn't being recognized in MDX, and the configuration you're adding might not be properly applied to Starlight's MDX setup.

Let's address both issues:

1. React Component in Starlight MDX

First, when using React components (like those from @icons-pack/react-simple-icons) in Starlight, you need to make sure the React integration is properly set up. Starlight uses Astro under the hood, and Astro requires explicit integration for React components.

Here's a revised approach:

// starlight-mdx-globals.js
import react from '@astrojs/react';

export default {
  name: 'starlight-mdx-globals',
  hooks: {
    'config:setup': ({ addIntegration, updateConfig, astroConfig }) => {
      // Check if React integration is already added
      const isReactLoaded = astroConfig.integrations.find(
        ({ name }) => name === '@astrojs/react'
      );
      
      // Add React integration if not already present
      if (!isReactLoaded) {
        addIntegration(react());
      }
      
      // Update MDX configuration
      updateConfig({
        markdown: {
          mdx: {
            // Add your global imports here
            globalImports: [
              // Import React icons
              "import { SiBun, SiCloudflareworkers, SiDeno, SiNodedotjs } from '@icons-pack/react-simple-icons';"
            ],
          },
        },
      });
    },
  },
};

2. Debugging Configuration

If you're seeing that the config object doesn't have markdown or MDX properties, it might be because Starlight is handling the MDX configuration differently. Let's try a more direct approach using Astro's configuration:

// starlight-mdx-globals.js
import react from '@astrojs/react';
#

export default {
name: 'starlight-mdx-globals',
hooks: {
'config:setup': ({ addIntegration, astroConfig }) => {
// Check if React integration is already added
const isReactLoaded = astroConfig.integrations.find(
({ name }) => name === '@astrojs/react'
);

  // Add React integration if not already present
  if (!isReactLoaded) {
    addIntegration(react());
  }
  
  // Directly modify Astro's MDX options
  // This is a more direct approach that works with Starlight
  astroConfig.markdown = astroConfig.markdown || {};
  astroConfig.markdown.mdx = astroConfig.markdown.mdx || {};
  astroConfig.markdown.mdx.globalImports = [
    "import { SiBun, SiCloudflareworkers, SiDeno, SiNodedotjs } from '@icons-pack/react-simple-icons';"
  ];
},

},
};


## 3. Alternative Approach

If the plugin approach still doesn't work, you can try a more direct method by extending Starlight's configuration in your `astro.config.mjs`:

```javascript
import { defineConfig } from 'astro/config';
import starlight from '@astrojs/starlight';
import react from '@astrojs/react';

export default defineConfig({
  integrations: [
    react(), // Add React integration explicitly
    starlight({
      title: 'My Docs',
      // Other Starlight config...
    }),
  ],
  // Configure MDX directly at the Astro level
  markdown: {
    mdx: {
      globalImports: [
        "import { SiBun, SiCloudflareworkers, SiDeno, SiNodedotjs } from '@icons-pack/react-simple-icons';"
      ]
    }
  }
});

If you're still experiencing issues, it might be worth checking if there are any specific requirements for using React components in Starlight or if there are any known limitations with global imports in this context.
