Question

Being new to node js and express has me wondering the best ways to get things done. Are there any specific conventions used in working with forms?

Answer 1

I use express-validator to validate input fields.

Here’s an example:

app.post('/login', routes.login.post);


//routes/login.js

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');
    }

    return;
  }

  //authenticate and set user in session here
};
