Errors, Errors Everywhere: How We Centralized and Structured Error Handling

Error handling in Go, initially simple, often becomes chaotic as a codebase grows. This post details the journey of creating a centralized, structured error framework using namespace codes for meaningful and traceable error logs. The new approach addresses inconsistent logs, improper error handling, and lack of categorization, promoting better organization and monitoring. Key design decisions include centralizing error declarations, standardizing error handling, and categorizing errors for effective monitoring. Practical examples illustrate the implementation and benefits of the updated error handling strategy.
