What are the best practices for structured logging in Go?

Structured logging in Go involves using a consistent format for log entries, making it easier to parse and analyze. Key practices include using a logging library like Logrus or Zap, including context in your logs, and ensuring logs are in JSON format for better integration with log management systems.

Can you explain why JSON format is preferred?

JSON format is preferred because it is easily readable by both humans and machines. It allows for structured data, making it simpler to filter and search logs in log management tools.

What logging libraries do you recommend for Go?

I recommend using Logrus for its simplicity and flexibility, or Zap for its performance and structured logging capabilities. Both are widely used in the Go community.

How can I include context in my logs?

You can include context by adding fields to your log entries, such as user IDs, request IDs, or any relevant metadata that can help in tracing issues.
