How to use it

package main

import (
	"os"
	"time"

	"github.com/deweppro/go-logger"
)

func main() {
	file, err := os.OpenFile("/tmp/demo.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666)
	if err != nil {
		panic(err)
	}

	defer file.Close()

	async := logger.NewAsync()
	async.SetOutput(file)
	async.Infof("async %d", 1)
	async.Warnf("async %d", 2)
	async.Errorf("async %d", 3)
	async.Debugf("async %d", 4)

	sync := logger.NewSync()
	sync.SetOutput(file)
	sync.Infof("sync %d", 1)
	sync.Warnf("sync %d", 2)
	sync.Errorf("sync %d", 3)
	sync.Debugf("sync %d", 4)

	<-time.After(time.Second)
}

Example log output:

{"time":1602721013,"type":"INF","data":"sync 1"}
{"time":1602721013,"type":"WRN","data":"sync 2"}
{"time":1602721013,"type":"ERR","data":"sync 3"}
{"time":1602721013,"type":"DBG","data":"sync 4"}
