Examples

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

import (
  "github.com/gofiber/fiber/v2"
  "github.com/gofiber/fiber/v2/middleware/recover"
)

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

// Default middleware config
app.Use(recover.New())

// This panic will be catch by the middleware
app.Get("/", func(c *fiber.Ctx) error {
	panic("I'm an error")
})

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

	// EnableStackTrace enables handling stack trace
	//
	// Optional. Default: false
	EnableStackTrace bool

	// StackTraceHandler defines a function to handle stack trace
	//
	// Optional. Default: defaultStackTraceHandler
	StackTraceHandler func(e interface{})
}

Default Config

var ConfigDefault = Config{
	Next:              nil,
	EnableStackTrace:  false,
	StackTraceHandler: defaultStackTraceHandler,
}
