Hi Syed, the userValidationRules() is a helper which uses the express-validator methods to intercept the request and enforce the validation, express-validator methods pass the results of the validations to the request, the validate is a middleware which checks if the request contains errors injected by the express-validator methods; as middlewares do, if there's an error in the request object, it returns the error response, if there's no error in the request object, it calls the next function allowing the request to continue to the next stage.
Hi thanks for the reply
I'm sorry, I'm still in learning the middleware. You said userValidationRules() is helper, but not a middleware, since because of the braces ()?, how these two (userValidationRules() and valiadate) differ from each other in that place.
My understanding is, the helper userValidationRules(), executed immediately, and send the errors ,if any, to validate middleware 'validate'?.
If i want to combine those two into one single middleware, how can I achieve that?
Thanks
Syed
