try change your if statement from this:

   if (!errors.isEmpty()) {
        console.log('there are no validation errors');
    } else {
        console.log(errors);
    }
}

to this:

    exports.addPost = (req, res, next) => {
        // Form validation rules
        check('title', '')
          .not()
          .isEmpty();
        check('excerpt', '')
          .not()
          .isEmpty();
       check('body', '')
          .not()
          .isEmpty();

        const errors = validationResult(req);

        const errors = validationResult(req);
        if (!errors.isEmpty()) {
           console.log(errors.array());
        }
}

Edit

If you would like to send an response to your front-end replace the console.log() command into res.send() then parse the answer in your front-end like so:

if (!errors.isEmpty()) {
           return res.send(errors.array());
         // can also send an status and catch it
        // by sending res.status(400).send(errors.array());
        }

Hopefully this makes sense
