Q: Logger migration

[loeffel-io]

Hello!

i am curious how i would migrate our zap gcloud implementation from v2.0.0-rc3 to v2.0.1 - i am thankful for every help!

func NewZap(development bool) (*zap.Logger, error) {
	var err error
	var logger *zap.Logger

	var loggerCfg = &zap.Config{
		Level:       zap.NewAtomicLevelAt(zapcore.InfoLevel),
		Development: development,
		Encoding:    "json",
		EncoderConfig: zapcore.EncoderConfig{
			TimeKey:       "time",
			LevelKey:      "severity",
			NameKey:       "logger",
			CallerKey:     "caller",
			MessageKey:    "message",
			StacktraceKey: "stacktrace",
			LineEnding:    zapcore.DefaultLineEnding,
			EncodeLevel: func(l zapcore.Level, enc zapcore.PrimitiveArrayEncoder) {
				switch l {
				case zapcore.DebugLevel:
					enc.AppendString("DEBUG")
				case zapcore.InfoLevel:
					enc.AppendString("INFO")
				case zapcore.WarnLevel:
					enc.AppendString("WARNING")
				case zapcore.ErrorLevel:
					enc.AppendString("ERROR")
				case zapcore.DPanicLevel:
					enc.AppendString("CRITICAL")
				case zapcore.PanicLevel:
					enc.AppendString("ALERT")
				case zapcore.FatalLevel:
					enc.AppendString("EMERGENCY")
				}
			},
			EncodeTime:     zapcore.RFC3339TimeEncoder,
			EncodeDuration: zapcore.MillisDurationEncoder,
			EncodeCaller:   zapcore.ShortCallerEncoder,
		},
		OutputPaths:      []string{"stdout"},
		ErrorOutputPaths: []string{"stderr"},
	}

	if logger, err = loggerCfg.Build(zap.AddStacktrace(zap.DPanicLevel)); err != nil {
		return nil, err
	}

	return logger, nil
}

logging.StreamServerInterceptor(grpczap.InterceptorLogger(logger)),

There's an example, does that help? https://github.com/grpc-ecosystem/go-grpc-middleware/blob/main/interceptors/logging/examples/zap/example_test.go

Yeah that works perfectly - was just curious if the lvls matches
Thanks @johanbrandhorst
