Mistake
My personal simple error handler built in Go.
Why Mistake?
Our approach begins with designing an unified error handler just for being more clear due to error package is extremely flexible and then Mistake born to be it.
Also we have a preference on go-playground/validator package and was integrated from the beginning.
This package is inspired on API error handler and we recommend used it for this.
How to start?
We have 2 ways to create a mistake object:
Create a new single error with id and message.
func New(statusCode int, messageID string, message string) *M
But if your project uses the package github.com/go-playground/validator, you can use this constructor and pass the error.
Internally the errors are converted to validator.ValidationErrors and retrieve Field and Tag attributes only.
func NewStructValidation(err error, statusCode int, messageID string, message string) *M
Dynamic messages
Mistake provides two functions for those messages where use verbs (%v).
Append values add all those variables will be replaced on the verbs.
Formatter takes the message with verbs and apply fmt.Sprintf on it, at the end append values will be dropped.
func AppendValue(v any)
func Formatter(message string) string
Here an example:
mistake.AppendValue(request.Email)
mt := mistake.New(
resources.DUPLICATED,
resources.CREATE_USER_EXIST,
mistake.Formatter("here is my email: '%v'"), // here is my email: 'mymy@emailme.com'
)
