How to validate and handle a form in Express (NodeJS).

[Chris Dew]

I know this has been asked before...
http://groups.google.com/group/express-js/browse_thread/thread/d402f31b2d895e67/fa85e36352e124c2
...but perhaps there is a more recent answer?

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 through the
template.

If the same validation could be used on the client side, that would be
great.

Has anyone used, or written, anything good?

Thanks,

Chris.

IMO most of this should be at the model level, so something

like mongoose would provide validations, you run them and display

the errors if any. on POST you can use express-messages / req.flash('error', msg)

to populate these as one solution

Generalhenry on Stackoverflow pointed me at https://github.com/caolan/forms,
which looks just the job. I'll give it a run over the next few days
and write a review.

There are reasons why forms should be only loosely coupled to models.
Authorisation is the first which comes to mind: an accounting model
may accept credit notes and invoices in a transaction model, but only
supervisors can create credit notes...

All the best,

Chris.

certainly, and it's nice to abstract regardless, I'm not saying it should always be backed by a model, but usually
