Core Error Handling Guidelines

Effective error handling in Capacitor apps requires balancing user experience with technical functionality. These guidelines help manage errors across platforms efficiently.

Writing Clear Error Messages

Good error messages should include three essential elements:

Use plain, understandable language while being technically accurate. For instance, instead of saying “HTTP 404 – Resource Not Found”, try “We couldn’t find the page. Check the URL or return home.”

Platform-Wide Error Standards

Ensuring consistent error handling across platforms involves a cohesive strategy:

• Centralized Error Catalog: Maintain a single repository for all error messages and codes to ensure consistency.
• Platform-Specific Handlers: Use native error handling tools while keeping the messaging uniform.
• Error Severity Levels: Classify errors by their impact and the actions users need to take.

Error Prevention Methods

1. Input Validation
Validate user inputs with real-time checks, ensuring proper data types and formats (e.g., email addresses or phone numbers).

2. Network Status Monitoring
Track network connectivity to prevent API errors. When offline, you can:

• Cache important data for offline use.
• Queue user actions for later processing.
• Display clear indicators for connectivity status.

3. Graceful Degradation
Support graceful degradation by:

• Falling back to local storage during cloud sync issues.
• Offering offline modes for critical tasks.
• Providing alternative ways to complete actions when full functionality isn’t available.

Following these steps helps create a reliable, user-friendly app experience while handling errors consistently across platforms. Proactive measures like these ensure smoother functioning and build user trust.

Handling Different Error Types

Form and Input Validation

Using a layered approach to input validation can improve user interactions while reducing errors. Provide clear, immediate feedback to users as they interact with the form:

To make the process smoother:

• Display format guidelines before users start typing.
• Validate inputs progressively as they are entered.
• Conduct a final validation when the form is submitted.

While these measures address input-level mistakes, managing network and API errors is equally critical for maintaining a smooth user experience.

Connection and API Issues

Network and API errors can disrupt user interactions, so it’s essential to monitor connections and handle API responses effectively:

1. Network Status Monitoring
   Keep track of connectivity to enable offline caching, queue operations for later, and update the user interface with the current status.

2. API Error Management

   Error Code	User-Facing Message	Background Action
   401/403	”Please log in again to continue”	Refresh authentication tokens
   404	”The requested information isn’t available”	Clear invalid cache entries
   429	”Please try again in a few minutes”	Use exponential backoff for retrying
   500+	“We’re experiencing technical difficulties”	Log error details for debugging purposes

By combining these strategies, you can minimize disruptions caused by connectivity issues and ensure users remain informed.

Platform-Specific Problems

Each platform comes with its own set of challenges, requiring tailored solutions to address unique issues effectively.

iOS-Specific Handling:

• Manage permissions, memory constraints, and keyboard interactions.
• Ensure smooth handling of system-specific behaviors.

Android-Specific Handling:

• Standardize back button navigation.
• Adjust for varying screen sizes and pixel densities.
• Handle fragment lifecycle complexities.

Web-Specific Handling:

• Resolve CORS issues using proper headers.
• Address browser compatibility concerns.
• Tackle challenges unique to Progressive Web Apps (PWAs).
