Express Passport (node.js) error handling

Question

I\'ve looked at how error handling should work in node via this question Error handling principles for Node.js + Express.js applications?, but I\'m not sure what passport\'s

Answer 1

What Christian was saying was you need to add the function

req.login(user, function(err){
  if(err){
    return next(err);
  }
  return res.send({success:true});
});

So the whole route would be:

app.post('/login', function(req, res, next) {
  passport.authenticate('local', function(err, user, info) {
    if (err) {
      return next(err); // will generate a 500 error
    }
    // Generate a JSON response reflecting authentication status
    if (! user) {
      return res.send(401,{ success : false, message : 'authentication failed' });
    }
    req.login(user, function(err){
      if(err){
        return next(err);
      }
      return res.send({ success : true, message : 'authentication succeeded' });        
    });
  })(req, res, next);
});
