Functions

func Handler

func Handler(w http.ResponseWriter, err interface{})

NotFound handler is called when no route is matched

func RecoveryHandler

func RecoveryHandler(w http.ResponseWriter, r *http.Request, err interface{})

RecoveryHandler handler is used when a panic happens

func Wrap

Wrap returns an error annotating err with a stack trace at the point Wrap is called, and the supplied message. If err is nil, Wrap returns nil.

Types

type Error

type Error struct {
	Code    int    `json:"-"`
	Message string `json:"error"`
}

Error is a custom error that implements the `error` interface. When creating errors you should provide a code (could be and http status code) and a message, this way we can handle the errors in a centralized place.

func New

func New(code int, message string) *Error

New creates a new instance of Error

func (*Error) Error

func (e *Error) Error() string
