In Episode 4, we focus on one of the most overlooked yet essential aspects of backend development: **logging and error handling**. A well-designed logging strategy and consistent error management make applications easier to debug, monitor, and maintain in production.
You'll learn how to structure logs, propagate errors properly, and build a backend that's both developer-friendly and production-ready.
📚 What You'll Learn
Why logging is critical in backend applications
Best practices for handling errors in Go
Creating meaningful and actionable log messages
Separating internal errors from user-facing responses
Building a consistent error handling strategy across layers
Improving debugging and observability in your Wallet application
By applying these practices early in the project, you'll create a more reliable codebase that's easier to maintain as new features are added.
