// Package zap provides fast, structured, leveled logging.
|
|
//
|
|
// For applications that log in the hot path, reflection-based serialization
|
|
// and string formatting are prohibitively expensive - they're CPU-intensive
|
|
// and make many small allocations. Put differently, using json.Marshal and
|
|
// fmt.Fprintf to log tons of interface{} makes your application slow.
|
|
//
|
|
// Zap takes a different approach. It includes a reflection-free,
|
|
// zero-allocation JSON encoder, and the base Logger strives to avoid
|
|
// serialization overhead and allocations wherever possible. By building the
|
|
// high-level SugaredLogger on that foundation, zap lets users choose when
|
|
// they need to count every allocation and when they'd prefer a more familiar,
|
|
// loosely typed API.
|
|
//
|
|
// Choosing a Logger
|
|
//
|
|
// In contexts where performance is nice, but not critical, use the
|
|
// SugaredLogger. It's 4-10x faster than other structured logging packages and
|
|
// supports both structured and printf-style logging. Like log15 and go-kit,
|
|
// the SugaredLogger's structured logging APIs are loosely typed and accept a
|
|
// variadic number of key-value pairs. (For more advanced use cases, they also
|
|
// accept strongly typed fields - see the SugaredLogger.With documentation for
|
|
// details.)
|
|
// sugar := zap.NewExample().Sugar()
|
|
// defer sugar.Sync()
|
|
// sugar.Infow("failed to fetch URL",
|
|
// "url", "http://example.com",
|
|
// "attempt", 3,
|
|
// "backoff", time.Second,
|
|
// )
|
|
// sugar.Infof("failed to fetch URL: %s", "http://example.com")
|
|
//
|
|
// By default, loggers are unbuffered. However, since zap's low-level APIs
|
|
// allow buffering, calling Sync before letting your process exit is a good
|
|
// habit.
|
|
//
|
|
// In the rare contexts where every microsecond and every allocation matter,
|
|
// use the Logger. It's even faster than the SugaredLogger and allocates far
|
|
// less, but it only supports strongly-typed, structured logging.
|
|
// logger := zap.NewExample()
|
|
// defer logger.Sync()
|
|
// logger.Info("failed to fetch URL",
|
|
// zap.String("url", "http://example.com"),
|
|
// zap.Int("attempt", 3),
|
|
// zap.Duration("backoff", time.Second),
|
|
// )
|
|
//
|
|
// Choosing between the Logger and SugaredLogger doesn't need to be an
|
|
// application-wide decision: converting between the two is simple and
|
|
// inexpensive.
|
|
// logger := zap.NewExample()
|
|
// defer logger.Sync()
|
|
// sugar := logger.Sugar()
|
|
// plain := sugar.Desugar()
|
|
//
|
|
// Configuring Zap
|
|
//
|
|
// The simplest way to build a Logger is to use zap's opinionated presets:
|
|
// NewExample, NewProduction, and NewDevelopment. These presets build a logger
|
|
// with a single function call:
|
|
// logger, err := zap.NewProduction()
|
|
// if err != nil {
|
|
// log.Fatalf("can't initialize zap logger: %v", err)
|
|
// }
|
|
// defer logger.Sync()
|
|
//
|
|
// Presets are fine for small projects, but larger projects and organizations
|
|
// naturally require a bit more customization. For most users, zap's Config
|
|
// struct strikes the right balance between flexibility and convenience. See
|
|
// the package-level BasicConfiguration example for sample code.
|
|
//
|
|
// More unusual configurations (splitting output between files, sending logs
|
|
// to a message queue, etc.) are possible, but require direct use of
|
|
// go.uber.org/zap/zapcore. See the package-level AdvancedConfiguration
|
|
// example for sample code.
|
|
//
|
|
// Extending Zap
|
|
//
|
|
// The zap package itself is a relatively thin wrapper around the interfaces
|
|
// in go.uber.org/zap/zapcore. Extending zap to support a new encoding (e.g.,
|
|
// BSON), a new log sink (e.g., Kafka), or something more exotic (perhaps an
|
|
// exception aggregation service, like Sentry or Rollbar) typically requires
|
|
// implementing the zapcore.Encoder, zapcore.WriteSyncer, or zapcore.Core
|
|
// interfaces. See the zapcore documentation for details.
|
|
//
|
|
// Similarly, package authors can use the high-performance Encoder and Core
|
|
// implementations in the zapcore package to build their own loggers.
