express-validator Break validator chain
<p>I am using express-validator plugin for express    </p>

<pre><code>var input = {
            'username': {
                notEmpty: true,
                isEmail: {
                    errorMessage: 'Invalid Email.'
                }
            },
            'password': {
                notEmpty: true,
                errorMessage: 'Invalid Password' // Error message for the parameter
            }
        };

    req.checkBody(input);
    var errors = req.validationErrors();
    if (errors) {
        console.log(errors);
    }
</code></pre>

<p>If I pass username as empty output is </p>

<pre><code>[ { param: 'username', msg: 'Invalid param', value: '' },
  { param: 'username', msg: 'Invalid Email.', value: '' },
  { param: 'password', msg: 'Invalid Password', value: '' } ]
</code></pre>

<p>how to brake the chain if anyone of the validation fails.</p>
