Day 43 of #100DaysOfCode — Error Handling + Async Wrapper

Error handling is crucial in backend development. Even well-written APIs can encounter issues, such as invalid data from users, non-existent resources, or failures from external services like databases. Effective error handling allows applications to respond with clear and consistent messages, rather than crashing or revealing sensitive information. Good backend systems manage errors gracefully by using meaningful messages and appropriate HTTP status codes. Thus, understanding error handling is essential for creating reliable and professional APIs. Today, for Day 43, the goal was to understand how error handling works and how errors are efficiently handled in the backend. Types of Errors in Backend Applications In backend development, errors usually fall into three main categories . Understanding these helps you design clean API responses and debugging strategies . 1. Operational Errors These are expected errors during normal application usage . Examples: User not found Invalid passwor
