Is there a preferred form handling and validation library for Express?
I'm really looking for a similar level of abstraction as is found in Django forms - i.e. validation and error reporting in the template.
If the same validation could be used on the client side, that would be great.
Has anyone used, or written, anything good?
This also looks viable and is still being developed: https://github.com/ctavan/express-validator
Here's an example of validating a form submission (login post request):
exports.login.post = function(req, res){
req.assert('username', 'Enter username').notEmpty();
req.assert('password', 'Enter password').notEmpty();
res.locals.err = req.validationErrors(true);
if ( res.locals.err ) {
if ( req.xhr ) {
res.send(401, { err: res.locals.err });
} else {
res.render('login', { err: res.locals.err });
}
return;
}
//authenticate user, data is valid
};
