Error Handling and Exceptions

Coming Soon

This lesson will cover Erlangโ€™s unique approach to error handling and the โ€œlet it crashโ€ philosophy. Youโ€™ll learn how to:

  • Understand Erlangโ€™s error handling philosophy
  • Use try-catch blocks for controlled error recovery
  • Implement defensive programming patterns
  • Handle different types of errors (throws, errors, exits)
  • Build fault-tolerant functions that gracefully handle failures

What Youโ€™ll Build

By the end of this lesson, youโ€™ll have implemented:

  • Robust error handling for chat server operations
  • Validation functions with comprehensive error reporting
  • Recovery strategies for common failure scenarios
  • Logging and monitoring for error tracking
  • A foundation for the fault-tolerant architecture

Key Concepts Preview

% Error handling patterns
try
validate_user_input(Input)
catch
error:{invalid_input, Reason} -> {error, Reason};
throw:validation_failed -> {error, invalid_data}
end.

This lesson builds on the structured data from Lesson 5 and prepares you for the process-based error handling weโ€™ll explore in Lesson 7.
