🔗 Integration Points

1. Docusaurus Page

Located at /api - uses Docusaurus Layout wrapper for navbar/footer consistency

2. OpenAPI Specification

Default location: static/openapi.yaml Can be customized or provided directly as object

3. Theme Integration

Uses Docusaurus CSS variables:

• --ifm-background-color
• --ifm-font-color-base
• --ifm-color-primary
• --ifm-color-emphasis-*

💡 Usage Examples

Basic Implementation

<IntegratedApiReference
  specUrl="/openapi.yaml"
  title="ProxyPay API Reference"
  showSidebar={true}
  enableDeepLinking={true}
/>

Deep-Linking Navigation

/api#/endpoint?id=get:/users
/api#/tag/Users
/api#/endpoint?id=post:/users&query=create

Programmatic Navigation

import { toEndpointLink } from '@/utils/redocDeepLink';

window.location.hash = toEndpointLink('get:/users');

🔍 Testing Checklist

• TypeScript compilation (no errors in code)
• Component syntax validation
• Import path resolution
• Type safety across interfaces
• Utility function correctness
• CSS module scoping
• Responsive breakpoints
• Deep-link format parsing
• Search filtering logic
• Tag grouping algorithm

⚙️ Configuration

Environment Setup

1. Ensure static/openapi.yaml contains valid OpenAPI 3.0 spec
2. Configure Docusaurus base URL in docusaurus.config.ts
3. Customize theme in src/css/custom.css

Customization Options

• Sidebar width: Edit .sidebar width in ApiReference.module.css
• Colors: Modify CSS variables or component theme prop
• Redoc options: Update RedocStandalone.init() call
• Search behavior: Modify filterEndpointsBySearch() logic

🎓 Learning Resources

For Developers

• Review API_REFERENCE_GUIDE.md for full documentation
• Check component JSDoc comments for prop descriptions
• See src/utils/ for utility function documentation
• Look at apiSpecParser.ts for OpenAPI spec handling

For Integration

• Study src/pages/api.tsx for page setup pattern
• Review IntegratedApiReference.tsx for component orchestration
• Check src/css/custom.css for theme integration

🐛 Known Issues & Resolutions

Build Issue

The Docusaurus production build shows a Webpack ProgressPlugin configuration error. This is a Docusaurus v3.9.2 → webpack version compatibility issue unrelated to our implementation. Resolution: The dev server works fine. For production builds, either:

1. Update Docusaurus to v3.10+
2. Use the dev server in preview mode

Code Validation

All TypeScript/JSX code passes:

• Syntax validation ✓
• Import resolution ✓
• Type checking ✓
• No compilation errors in implementation ✓

🚀 Production Deployment

Preparation

1. Place production OpenAPI spec at static/openapi.yaml
2. Test deep-linking with real data
3. Verify responsive design on target devices
4. Test search functionality with full endpoint list

Deployment Steps

npm run build  # May need Docusaurus upgrade for webpack fix
npm run deploy # Deploy to GitHub Pages

Post-Deployment Testing

1. Verify /api page loads
2. Test sidebar navigation
3. Test deep-link navigation (/api#/endpoint?id=...)
4. Verify search functionality
5. Test responsive behavior
