isDate()

Hi,

I hope somebody can help me figure out what I’m doing wrong:

req.checkBody('profile.dateOfBirth', 'Date of birth needs to be a valid date').isDate({format: 'DD-MM-YYYY'});

Yields the following validation error:

{
    "param": "profile.dateOfBirth",
    "msg": "Date of birth needs to be a valid date",
    "value": "22-06-1977"
}

I tried with different format strings, no format string, etc but the result is always the same. All other validations (notEmpty, isAlpha, len, etc) on other params work as expected only isDate consistently fails.

Hi @afrikhero @Pedro-Sousa-da-Rocha, isISO8601 is probably the best method from validator to validate dates.

express-validator is simply a middleware wrapper of validator.js, so all available validators are listed on their README. Just looking at their docs/code, the isDate method does not accept an object for specifying a format. Behind the scenes, this is how it is validated:

    validator.isDate = function (str) {
        return !isNaN(Date.parse(str));
    };

So in order for isDate to work, you will either need to:

1. Remove the object when calling it.
2. Create a PR to validator.js to add the format functionality.
3. Create a custom validator that checks for that format using regex or moment.js’s isValid().

Let me know if this works. If so, please close the issue.
