stormpath, express - check if user exists in route - express

Question

Working with this example (https://stormpath.com/blog/build-nodejs-express-stormpath-app)
I added a route and a view to display some of any users account profile.
username: jsmith
http://localhost:3000/-jsmith (note the -)
which works fine - even if no user is logged in.
If a user doesn't exist, the app just hangs and nothing is returned.

Q:
How do I test if a user exist, and return to view, "User not found"?
Thanks, Rob
app.get('/-:id', function (req, res, next) {
console.log('the response will be sent by the next function ...');
var id = req.params.id;
console.log(id);
next();
},
function (req, res) {
var id = req.params.id;
req.app.get('stormpathApplication').getAccounts({ username: id }, (err, accounts) => {
if (err) throw err;
accounts.each((account, cb) => {
console.log('Found matching account:', account);
cb();
console.log('username:' + account.username)
res.render('user', {
email: account.email,
surname: account.surname,
account:account // this passes object, which can be used in view, no need to define email:account.email in server.js
});
});
});
}
);

It looks like this is what you want:
app.get('/-:id', function(req, res, next) {
var id = req.params.id;
var spApp = req.app.get('stormpathApplication');
var acc;
spApp.getAccounts({ username: id }, function(err, accounts) {
if (err) {
return res.send('An error occured. Please try again.');
}
accounts.each(function(account, cb) {
acc = account;
cb();
}, function() {
if (!acc) {
return res.send('User not found.');
}
return res.render('user', {
email: account.email,
surname: account.surname,
account:account
});
});
});
});
