zaphttplog

zaphttplog

zaphttplog provides a structured request/response logging implementation based on zap. It provides much the same functionality and API as Chi's httplog, but backed by zap instead of zerolog.

This is useful for cases where you've standardized on zap for logging and want detailed, structured request logging as part of your HTTP middleware

Usage

package main

import (
	"log"
	"net/http"

	"github.com/Silicon-Ally/zaphttplog"
	"github.com/go-chi/chi/v5"
	"github.com/go-chi/chi/v5/middleware"
	"go.uber.org/zap"
)

func main() {
	// Configure your logger for your environment.
	logger, err := zap.NewProduction()
	if err != nil {
		log.Fatalf("failed to init logger: %v", err)
	}

	// Initialize the router and set basic middleware.
	r := chi.NewRouter()
	r.Use(zaphttplog.NewMiddleware(logger))
	r.Use(middleware.Recoverer)

	// An example handler.
	r.Get("/", func(w http.ResponseWriter, r *http.Request) {
		w.Write([]byte("root."))
	})

	if err := http.ListenAndServe(":8080", r); err != nil {
		log.Fatalf("http.ListenAndServe: %v", err)
	}
}

Running this would look like:

# Run the server
go run ./examples

# In a new terminal, make a request
curl localhost:8080

In the first terminal, you should observe a log line like:

{"level":"info","ts":1689792663.2690268,"caller":"zaphttplog/zaphttplog.go:201","msg":"GET / - 200 OK","httpRequest":{"requestURL":"http://localhost:8080/","requestMethod":"GET","requestPath":"/","remoteIP":"127.0.0.1:57954","proto":"HTTP/1.1","scheme":"http","header":{"user-agent":"curl/8.1.2","accept":"*/*"}},"httpResponse":{"status":200,"bytes":5,"elapsed":0.000014111}}
