"go.uber.org/zap"
"go.uber.org/zap/zapcore"
)
Next, set up a basic logger using Zap's presets which provide reasonable defaults for most use cases:
logger, _ := zap.NewProduction()
This constructs a new logger with default configurations suitable for production environments. For development environments, you might want to use a more verbose logger:
logger, _ := zap.NewDevelopment()
Both NewProduction() and NewDevelopment() create loggers that are ready to use without further adjustments. These default loggers include features like structured logging and leveled logging.
After creating the logger, you can immediately start using it in your application:
logger.Info("Zap Logger integrated successfully!",
zap.String("environment", "production"),
zap.Int("attempt", 1),
zap.Duration("backoff", time.Second),
)
Zap Logger allows you to log with different levels of severity, ranging from debug logs with logger.Debug() for detailed information valuable during the development phase, through to critical errors with logger.Fatal(), which logs the message and then calls os.Exit(1).
It is a good habit to defer the syncing of the logger to ensure all buffered logs are flushed:
defer logger.Sync()
Keep in mind that logger.Sync() is especially important for asynchronous loggers or when your application might terminate abruptly. Wrapping up the integration, you simply replace instances where you'd normally use Go's default log package with the corresponding calls to your Zap logger instance.
Installing and setting up Zap Logger in your Go projects markedly uplifts your logging mechanism, providing a rich set of features without compromising on performance.
