ZapChi

[!IMPORTANT] This package is a modified fork of https://github.com/leosunmo/zapchi, pending merged of https://github.com/leosunmo/zapchi/pull/3. The original package appears to be abandoned.

Logging middleware for Chi using the Zap logging library.

Can take either a flat or sugared logger, named or unnamed.

The Zap log level used will depend on on the status code returned by the response.

package main

import (

	"github.com/go-chi/chi/v5/middleware"
	"github.com/syntaqx/zapchi"
	"go.uber.org/zap"
)

func main() {
	// Logger with default production config
	logger, _ := zap.NewProduction()
	defer logger.Sync() // Flush buffer

	// Service
	r := chi.NewRouter()

	// Panic recovery should happen first
	r.Use(middleware.Recoverer)

	// Request ID should be before logger
	r.Use(middleware.RequestID)

	// Zap logger with logger name router
	r.Use(zapchi.Logger(logger, "router"))

	// Sugared logger with no logger name
	// r.Use(zapchi.Logger(logger.Sugar(),""))

	r.Get("/", func(w http.ResponseWriter, r *http.Request) {
		w.Write([]byte("hello world"))
	})

	r.Get("/panic", func(w http.ResponseWriter, r *http.Request) {
		panic("panicing!")
	})

	r.Get("/info", func(w http.ResponseWriter, r *http.Request) {
		w.Header().Add("Content-Type", "text/plain")
		w.Write([]byte("info level"))
