Structured Logging and Error Handling

In this section of the book, we’re going to take a short break from working on our API endpoints and focus on making some improvements to the way that we handle exceptions and errors.

You’ll learn how to:

• Create a custom logger for writing structured, levelled, log messages in JSON format.
• Integrate the custom logger with your handlers and Go’s http.Server, so that all log messages are written to one location in a consistent format.
• How to recover and gracefully handle panics in your application middleware and handlers.
