Functions

func WithLogging

func WithLogging(handler http.Handler, logger *zap.Logger) http.Handler

WithLogging wraps http.Handler with logging middleware It logs request method, path, remote address, response status and latency in nanoseconds See ExampleWithLogging for usage

Example

// Create a zap test logger
logger, _ := zap.NewProduction()
defer logger.Sync()

http.HandleFunc("/api/data", func(w http.ResponseWriter, r *http.Request) {
	w.WriteHeader(http.StatusCreated)
	w.Write([]byte("Success!"))
})

// Wrap the test handler with our logging middleware
http.ListenAndServe(":8080", http_logger.WithLogging(http.DefaultServeMux, logger))
