Summary: Technical reference for the Neon documentation MDX component system. Covers file layout under src/components/pages/doc/, the sharedMdxComponents.js registry, and the two icon loading strategies. TechCards loads dynamic SVG files from /public/images/technology-logos/. DetailIconCards uses static inline imports mapped in component code. Use this page when adding, modifying, or debugging MDX components, not when looking for usage examples or icon names.

Neon documentation uses MDX (Markdown + JSX) to enable React components within markdown content. The component system is built on top of this foundation.

MDX Content
  ↓
Component Registry (sharedMdxComponents)
  ↓
React Components (src/components/pages/doc/)
  ↓
Rendered HTML

• sharedMdxComponents.js - Main component registry
• src/components/pages/doc/ - Component implementations
• content/docs/ - MDX content files
• content/docs/shared-content/ - Shared template content

Most MDX components follow a consistent pattern in the Neon website repository:

src/components/pages/doc/
├── {component-name}/
│   ├── {component-name}.jsx          # Main component implementation
│   ├── index.js                      # Export file
│   └── images/                       # Component-specific assets
│       └── {icons}.inline.svg        # Inline SVG icons
├── shared/                           # Shared components
│   ├── request-form/
│   └── ...
└── ...

Let's explore the DocsList component as an example:

src/components/pages/doc/docs-list/
├── docs-list.jsx                     # Main component implementation
├── index.js                          # Export: export { default } from './docs-list'
└── images/                           # Component-specific images
    ├── docs.inline.svg
    └── repo.inline.svg

When exploring a component, look for these files:

• Component Definition ({component-name}.jsx)

  • Contains the React component code
  • Defines props and their types
  • Implements the rendering logic
  • May include styled components or CSS modules

• Index File (index.js)

  • Usually a simple export: export { default } from './component-name';
  • Makes the component importable from the directory

• Images Directory (images/)

  • Contains SVGs, icons, or other assets used by the component
  • For icon-based components, this is where you'll find available icons

Components are registered in sharedMdxComponents.js to make them available in MDX files:

// sharedMdxComponents.js
import DocsList from '../src/components/pages/doc/docs-list';
import TechCards from '../src/components/pages/doc/tech-cards';
// ... other imports

export const sharedMdxComponents = {
  DocsList,
  TechCards,
  // ... other components
};

The sharedMdxComponents object is passed to the MDX processor, making all registered components available in markdown files:

// In MDX files
<DocsList title="Related documentation">
  <a href="/docs/guides/node">Node.js Guide</a>
</DocsList>

• Global: Components registered in sharedMdxComponents are available in all MDX files
• Local: Some components may be registered locally for specific pages
• Conditional: Components may be conditionally available based on page context

TechCards icons are loaded dynamically from the public directory. If the file exists, it will be rendered. Otherwise, the image will be broken or missing.

File Requirements:

• Icons must exist in /public/images/technology-logos/
• Format: {icon-name}.svg and {icon-name}-dark.svg
• Case-sensitive naming

DetailIconCards icons are statically imported and mapped:

// DetailIconCards component implementation
import Prisma from './images/prisma.inline.svg';
import NodeJs from './images/node-js.inline.svg';
// ... other imports

const icons = {
  prisma: Prisma,
  'node-js': NodeJs,
  // ... other mappings
};

const Icon = icons[icon];

File Requirements:

• Icons must be imported as inline SVGs
• Must be explicitly mapped in the component code
• Case-sensitive naming

Shared content components load from templates in content/docs/shared-content/:

content/docs/shared-content/
├── feature-beta.md
├── public-preview.md
├── early-access.md
└── ...

Templates are registered in shared-content/index.js:

// shared-content/index.js
export const sharedContent = {
  'feature-beta': () => import('./feature-beta.md'),
  'public-preview': () => import('./public-preview.md'),
  // ... other templates
};

Shared content is loaded dynamically:

// In MDX files
<FeatureBeta />  // Loads content from feature-beta.md
<PublicPreview /> // Loads content from public-preview.md

Shared templates are standard MDX files with frontmatter:

---
title: Feature Beta
description: Beta feature announcement
---

This feature is currently in beta...

1. Create Component Directory

   mkdir src/components/pages/doc/my-component

2. Create Component File

   // src/components/pages/doc/my-component/my-component.jsx
   import React from 'react';
   
   const MyComponent = ({ title, children }) => {
     return (
       <div className="my-component">
         <h3>{title}</h3>
         {children}
       </div>
     );
   };
   
   export default MyComponent;

3. Create Index File

   // src/components/pages/doc/my-component/index.js
   export { default } from './my-component';

4. Register Component

   // sharedMdxComponents.js
   import MyComponent from '../src/components/pages/doc/my-component';
   
   export const sharedMdxComponents = {
     // ... existing components
     MyComponent,
   };

5. Test Component

   <!-- In any MDX file -->
   
   <MyComponent title="Test">This is a test of my new component.</MyComponent>

1. Locate Component

   • Find the component in src/components/pages/doc/{component-name}/
   • Check the main .jsx file for implementation

2. Make Changes

   • Modify the component logic in the .jsx file
   • Update props, styling, or functionality as needed

3. Test Changes

   • Check that the component renders correctly
   • Verify that existing usage still works
   • Test edge cases and error conditions

1. Check Console Errors

   • Look for JavaScript errors in browser console
   • Check for missing imports or undefined variables

2. Verify Registration

   • Ensure component is properly exported from index.js
   • Confirm component is registered in sharedMdxComponents

3. Check File Paths

   • Verify all imports resolve correctly
   • Check that asset files exist in expected locations

4. Test in Isolation

   • Create a simple test page with just the component
   • Remove other components to isolate issues

1. Content Loading: MDX files are loaded from content/docs/
2. Component Resolution: sharedMdxComponents are injected into MDX context
3. Transformation: MDX is transformed to React components
4. Rendering: Components are rendered to HTML

MDX Files → MDX Processor → React Components → HTML Output
     ↓              ↓              ↓              ↓
content/docs/ → sharedMdxComponents → src/components/ → public/

• Code Splitting: Components are code-split for performance
• Asset Optimization: Images and SVGs are optimized during build
• Caching: Static assets are cached for faster loading

1. Component Not Found

   • Check that component is registered in sharedMdxComponents
   • Verify the component name matches exactly (case-sensitive)
   • Ensure the component is properly exported

2. Icon Not Displaying

   • For TechCards: Check if SVG file exists in /public/images/technology-logos/
   • For DetailIconCards: Check if icon is mapped in component code
   • Verify icon name spelling and case

3. Build Errors

   • Check for syntax errors in component files
   • Verify all imports resolve correctly
   • Ensure all required dependencies are installed

4. Styling Issues

   • Check CSS class names and specificity
   • Verify that styles are properly imported
   • Test in different browsers and screen sizes

1. Console Logging

   const MyComponent = (props) => {
     console.log('MyComponent props:', props);
     return <div>...</div>;
   };

2. React DevTools

   • Use React DevTools to inspect component hierarchy
   • Check props and state values
   • Verify component rendering

3. Network Tab

   • Check for failed asset requests
   • Verify that images and SVGs load correctly
   • Look for 404 errors

4. Source Maps

   • Enable source maps for better error tracking
   • Use browser dev tools to step through code

1. Bundle Size

   • Keep components lightweight
   • Use code splitting for large components
   • Optimize images and assets

2. Rendering Performance

   • Avoid expensive operations in render methods
   • Use React.memo for expensive components
   • Implement proper key props for lists

3. Asset Loading

   • Optimize image sizes and formats
   • Use appropriate loading strategies
   • Consider lazy loading for non-critical components
