zlogger-lib

• logger instances created are of 2 types - [DEBUG]/[RELEASE]
• instances created depends on gin mode of the code.

Default log levels

• Error
• Warn
• Info
• Debug

Usage

Fetch the latest version of zlogger-lib

GOPROXY=https://proxy.golang.org GO111MODULE=on go get github.com/Zbyteio/[email protected]

Create an app logger

• use this logger to log throughout the library

appLogger := zlogger.NewZlogger(gin.DebugMode)

............

ZBlocksAppDebugLogger.Debugf("%s", "success print debug via applogger[DEBUG]")

Create a gin logger

• use this logger as middleware for gin route logging

ginLogger := zlogger.NewGinLogger(gin.DebugMode)

............
ginEng := gin.New()


ginEng.Use(
    ZBlocksGinDebugLogger.GinRequestLoggerMiddleware(),
)
ginEng.GET("/abc", func(c *gin.Context) {
    c.String(http.StatusOK, "Welcome Gin Server")
})

Create a gorm logger

• use this for replacing gorm trace logging
• use this for logging at database level inside code

gormLogger := zlogger.NewGormLogger(gin.DebugMode)

............

ZBlocksGormDebugLogger.SetAsDefault()
db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{
  Logger: ZBlocksGormDebugLogger,
})

Best Practices

[ ] Initialise only once [ ] Use as global variable in each package.

TODO

• remove setting of gin mode, maintain local state instead
• Add basic configurability
• Create a top level logger that init all the loggers
• Use factory pattern to instantiate the library
• Gorm Logger release mode not working
• Add custom log levels if required later
