Error Handling Patterns & Best Practices

Comprehensive error handling strategies across languages and frameworks for building resilient, fault-tolerant software systems.

Error Handling Philosophy

Fail Fast

Detect problems as early as possible and report them immediately. Do not let invalid state propagate through the system.

• Validate inputs at system boundaries
• Use assertions for invariants during development
• Throw on impossible states rather than returning defaults
• Prefer compile-time checks over runtime checks

Fail Gracefully

When failure is unavoidable, degrade functionality rather than crashing the entire system.
