// Package valid wraps github.com/go-playground/validator/v10 behind a minimal
|
||
|
|
// Validator interface, returning xerrors-typed errors with stable codes.
|
||
|
|
//
|
||
|
|
// The backend library is fully hidden — callers interact only with Validator
|
||
|
|
// and *xerrors.Err. Swapping the backend in the future requires no API changes.
|
||
|
|
//
|
||
|
|
// Usage:
|
||
|
|
//
|
||
|
|
// v := valid.New()
|
||
|
|
// if err := v.Struct(req); err != nil {
|
||
|
|
// // err is *xerrors.Err with Code() == xerrors.ErrInvalidInput
|
||
|
|
// // err.Fields()["field"] contains the failing field name
|
||
|
|
// }
|
||
|
|
//
|
||
|
|
// // Spanish messages
|
||
|
|
// v := valid.New(valid.WithMessageProvider(valid.SpanishMessages))
|
||
|
|
//
|
||
|
|
// Struct tags follow go-playground/validator conventions:
|
||
|
|
//
|
||
|
|
// type CreateUserReq struct {
|
||
|
|
// Email string `json:"email" validate:"required,email"`
|
||
|
|
// Age int `json:"age" validate:"min=18"`
|
||
|
|
// }
