Log initializer written with golang. Currently, support zap logger as default logger and lumberjack as log rotation

We combined zap config and lumberjack config in the same config file Both of the configs could keep same format as it
In order to init zap logger with full log rotation, rk-logger support three different utility functions
- With zap lumberjack config file path
- With zap lumberjack config as byte array
- With zap config and lumberjack config
config:
---
level: debug
encoding: console
outputPaths:
- stdout
- logs/rk-logger.log
errorOutputPaths:
- stderr
initialFields:
initFieldKey: fieldValue
encoderConfig:
messageKey: messagea
levelKey: level
nameKey: logger
timeKey: time
callerKey: caller
stacktraceKey: stacktrace
callstackKey: callstack
errorKey: error
timeEncoder: iso8601
fileKey: file
levelEncoder: capital
durationEncoder: second
callerEncoder: full
nameEncoder: full
sampling:
initial: '3'
thereafter: '10'
maxsize: 1
maxage: 7
maxbackups: 3
localtime: true
compress: true
Example:
func NewZapLoggerWithConfPathExample() {
// get current working directory
dir, _ := os.Getwd()
// init logger
logger, _, _ := rk_logger.NewZapLoggerWithConfPath(path.Clean(path.Join(dir, "/assets/zap.yaml")), rk_logger.YAML)
// use it
logger.Info("NewZapLoggerWithConfPathExample")
}
Example:
func NewZapLoggerWithBytesExample() {
bytes := []byte(`{
"level": "debug",
"encoding": "console",
"outputPaths": ["stdout", "logs/rk-logger.log"],
"errorOutputPaths": ["stderr"],

}
},

}`)
logger, _, err := rk_logger.NewZapLoggerWithBytes(bytes, rk_logger.JSON)
logger.Info("NewZapLoggerWithBytesExample")
}
func NewZapLoggerWithConfExample() {

}
config := &zap.Config{

EncoderConfig: encodingConfig,

}
logger, _ := rk_logger.NewZapLoggerWithConf(config, &lumberjack.Logger{})
logger.Info("NewZapLoggerWithConfExample")
}
