Rate Limit Error Handling

Overview

This feature automatically detects GitHub API rate limit errors and shows a user-friendly modal with instructions on how to resolve the issue.

How It Works

  1. Error Detection: All GitHub API calls are monitored for rate limit errors
  2. Modal Display: When a rate limit is detected, a modal appears with helpful instructions
  3. Multilingual Support: Messages are shown in English or Russian based on user language preference
  4. Non-Blocking: Users can close the modal and continue using other features

Error Patterns Detected

The system detects rate limit errors by checking for these patterns in error messages:

  • "rate limit"
  • "api rate limit"
  • "too many requests"
  • "403 forbidden" (GitHub returns 403 for rate limits)
  • "secondary rate limit"
  • "exceeded"
  • "limit exceeded"

User Experience

English Version

Rate Limit Exceeded
You have exceeded the GitHub API rate limit. To continue using the application, please enable VPN or change your IP address.

What to do:
• Enable VPN
• Change your IP address
• Wait for limit reset (usually 1 hour)

Russian Version

Превышен лимит запросов
Вы превысили лимит запросов к API GitHub. Чтобы продолжить пользоваться приложением, включите VPN или смените IP-адрес.

Что делать:
• Включите VPN
• Смените IP-адрес
• Подождите сброса лимита (обычно 1 час)

Implementation Details

Files Modified

  • src/components/RateLimitModal.tsx - Modal component with bilingual messages
  • src/lib/rateLimit.tsx - Context provider for modal management
  • src/lib/apiErrorHandler.ts - Error detection and handling logic
  • src/lib/github.ts - Updated to use new error handler
  • src/App.tsx - Added RateLimitProvider to component tree

Security Considerations

  • Rate limit events are logged securely without exposing tokens
  • Modal can be dismissed by user
  • No sensitive information is displayed in error messages
  • Compatible with existing error handling systems

Testing

To test the rate limit modal:

  1. Temporarily modify the token to an invalid one
  2. Make API calls until rate limit is triggered
  3. The modal should appear automatically

Future Enhancements

  • Automatic retry with exponential backoff
  • Rate limit status display in UI
  • Integration with GitHub's rate limit headers for proactive warnings
