This is a sample code to initialize Context Logging

To Initialize Logger

logger.InitializeLogger()

Logger struct

type contextLogger struct { entry *logrus.Entry }

For every Request this contextLogger will be initialized

r.WithContext(logger.WithLogger(r.Context())) in defaultmiddleware.go

func WithLogger(ctx context.Context) context.Context { return context.WithValue(ctx, loggerKey{}, newContextLogger(ctx)) }

To Use Logging anywhere

import logger "github.com/tandonraghav/go-logging/logging"

logger.GetLogger(r.Context()).Info( "applyMid=",applyMid)

The Context is passed around and all Log lines will be printed with Basic info like requestID, Username etc.
