Examples

Import the middleware package that is part of the Fiber web framework

import (
  "github.com/gofiber/fiber/v3"
  "github.com/gofiber/fiber/v3/middleware/pprof"
)

After you initiate your Fiber app, you can use the following possibilities:

// Default middleware
app.Use(pprof.New())

In systems where you have multiple ingress endpoints, it is common to add a URL prefix, like so:

// Default middleware
app.Use(pprof.New(pprof.Config{Prefix: "/endpoint-prefix"}))

This prefix will be added to the default path of "/debug/pprof/", for a resulting URL of: "/endpoint-prefix/debug/pprof/".

Config

// Config defines the config for middleware.
type Config struct {	
	// Next defines a function to skip this middleware when returned true.
	//
	// Optional. Default: nil
	Next func(c fiber.Ctx) bool

	// Prefix defines a URL prefix added before "/debug/pprof".
	// Note that it should start with (but not end with) a slash.
	// Example: "/federated-fiber"
	//
	// Optional. Default: ""
	Prefix string
}

Default Config

var ConfigDefault = Config{
	Next: nil,
}
