Logger

Cyclops provides lightweight logger. It simple to use and is based on contexts

package main

import (
	"net/http"
	"github.com/flannel-dev-lab/cyclops/v2/logger"
)

func Hello(w http.ResponseWriter, r *http.Request) {
	ctx := r.Context()
	ctx = logger.AddKey(ctx, "hello", "world")

	logger.Info(ctx, "info")
}

The above code will printout

{
  "INFO": "info",
  "hello": "world"
}

You can add any number of keys to the log you want to track. There are other log levels available as well Debug, Warn, Error that can be tuned as per your use case
