📝 Development Notes

Adding API Integration

When ready to connect to your backend API, update the following:

1. Replace mock data in App.js with API calls
2. Add axios or fetch for HTTP requests:

   npm install axios

3. Create a services/ folder for API functions
4. Add authentication/authorization logic

Environment Variables

Create a .env file in the root directory:

REACT_APP_API_URL=https://your-api-endpoint.com
REACT_APP_HUB_VERSION=1.0.0

🔒 Security Considerations

• Admin-only features are UI-protected (add backend validation)
• Connection requests require registration verification
• Document transmission uses secure Hub connections
• User-specific notifications ensure privacy

This creates an optimized production build in the build/ folder.

💡 Tips for Visual Studio Users

1. IntelliSense: Visual Studio provides excellent IntelliSense for React. Install the "JavaScript and TypeScript" workload if not already installed.

2. Debugging: You can debug React apps directly in Visual Studio:

   • Set breakpoints in your code
   • Press F5 to start debugging
   • Choose "Chrome" as the debug target

3. Extensions: Recommended Visual Studio extensions:

   • React code snippets
   • Prettier - Code formatter
   • ESLint

4. Hot Reload: The development server supports hot module replacement - your changes will appear instantly without losing application state.

🚨 Troubleshooting

Common Issues:

1. npm install fails: Delete node_modules and package-lock.json, then try again
2. Port 3000 in use: Change the port in package.json: "start": "set PORT=3001 && react-scripts start"
3. Tailwind styles not working: Ensure Tailwind is properly configured in tailwind.config.js
