API Integration

The plugin uses the OpenWeatherMap Current Weather Data API:

• Endpoint: https://api.openweathermap.org/data/2.5/weather
• Caching: 15-minute WordPress Transients
• Rate Limiting: Respects API limits with proper error handling
• Security: API key stored securely, never exposed to frontend

Caching Strategy

Weather data is cached using WordPress Transients:

• Cache Duration: 15 minutes
• Cache Key: Based on location and units (weather_block_{md5(location+units)})
• Cache Invalidation: Automatic expiration, manual clearing available
• Performance: Reduces API calls and improves page load times

Testing

Running Tests

# PHP Unit Tests
composer test
# or
./vendor/bin/phpunit

# JavaScript Unit Tests
npm run test:unit

# End-to-End Tests
npm run test:e2e

# All Tests
npm test

Test Coverage

The plugin maintains high test coverage:

• PHP: 80%+ coverage with PHPUnit
• JavaScript: 80%+ coverage with Jest
• Visual Regression: Playwright tests for UI consistency

Security

Security Features

• Nonce Verification: All API requests use WordPress nonces
• Data Sanitization: All user input and API responses are sanitized
• Capability Checks: API access restricted to users with edit_posts capability
• Input Validation: Location and units parameters are validated
• Error Logging: Security events are logged for monitoring

API Key Security

• Store API keys in wp-config.php (recommended) or use a secure settings page
• Never commit API keys to version control
• Use environment variables in production
• Regularly rotate API keys

Accessibility

The Weather Block is designed to be fully accessible:

• WCAG 2.1 AA Compliant: Meets accessibility standards
• Screen Reader Support: Proper ARIA labels and descriptions
• Keyboard Navigation: Full keyboard accessibility
• High Contrast: Supports high contrast mode
• Reduced Motion: Respects user's motion preferences
• Focus Management: Clear focus indicators

Internationalization

The plugin is fully internationalized:

• Text Domain: weather-block

• RTL Support: Right-to-left language support
• Date/Time Formatting: Respects WordPress locale settings

Adding Translations

1. Generate POT file: wp i18n make-pot . languages/weather-block.pot
2. Create language-specific PO files
3. Compile to MO files for production
