# Log
This is a wrapper over [Uber zap](https://github.com/uber-go/zap) library that replaces the sugared logger.
Features:
* Syslog integration
* Automatic stacktraces for errors
* Context aware tracing ID
* Easy to use
* Fast!
Example:
```go
logger, err := log.NewProduction(log.Config{
Mode: log.SyslogMode,
Level: zapcore.InfoLevel,
Encoding: log.JSONEncoding,
})
if err != nil {
t.Fatal(err)
}
logger.Info(ctx, "Could not connect to database",
"sleep", 5*time.Second,
"error", errors.New("I/O error"),
)
logger.Named("sub").Error(ctx, "Unexpected error", "error", errors.New("unexpected"))
```
