error-handling-patterns

Type-safe error handling in TypeScript uses Result types and discriminated unions to manage errors explicitly. This prevents unexpected crashes by ensuring all potential failure modes are clearly defined and handled by the caller, leading to more predictable application behavior.

Managing exceptions involves using custom error classes for better categorization and recovery mechanisms like retries and fallback values. This approach addresses scenarios requiring robust error management for network operations and validation failures, enhancing overall application resilience.

A Result type pattern works by explicitly defining success and failure states, forcing callers to handle validation failures safely. It utilizes discriminated unions to ensure that errors are managed predictably rather than throwing uncaught exceptions.

Yes, custom error classes can define specific categories for network operation failures. This allows for better error categorization and handling, ensuring that transient failures can be managed effectively with recovery patterns like retries and fallback values.

Discriminated unions should be used for exception management when building APIs or applications requiring robust error handling. They ensure all potential failure modes, such as not found errors and network issues, are explicitly defined and handled gracefully.
