Variables

var ConfigDefault = Config{
	SuccessHandler: func(c *fiber.Ctx) error {
		return c.Next()
	},
	ErrorHandler: func(c *fiber.Ctx, err error) error {
		if errors.Is(err, ErrMissingOrMalformedAPIKey) {
			return c.Status(fiber.StatusUnauthorized).SendString(err.Error())
		}
		return c.Status(fiber.StatusUnauthorized).SendString("Invalid or expired API Key")
	},
	KeyLookup:  "header:" + fiber.HeaderAuthorization,
	AuthScheme: "Bearer",
	ContextKey: "token",
}

ConfigDefault is the default config

var ErrMissingOrMalformedAPIKey = errors.New("missing or malformed API Key")

When there is no request of the key thrown ErrMissingOrMalformedAPIKey

Functions

func New

func New(config ...Config) fiber.Handler

New creates a new middleware handler
