How can I handle errors effectively using Zerolog?

To handle errors effectively with Zerolog, you can use structured logging to capture error details. Start by logging the error message and any relevant context.

Can you show me a code example of logging an error?

Sure! Here's a simple example:

if err != nil {
    logger.Error().Err(err).Msg("An error occurred while processing the request")
}

What if I want to log additional context with the error?

You can add more context by using fields. For example:

logger.Error().Err(err).Str("userID", userID).Msg("Failed to retrieve user data")

Is there a way to log errors to a file instead of the console?

Yes, you can configure Zerolog to write to a file by using a file writer. Here's how:

file, err := os.OpenFile("logfile.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666)
if err == nil {
    logger = logger.Output(file)
}
