Show a list of registered users (passport, sessions, possibly sockets)?

Question

Introduction:

Ok, I put together a good application that allows users to log in (node.js, passportjs, mongodb). Now, while promoting the application, I need to find out who is logged in.

---

Theory:

So this idea just hit me, I think the best idea would be to transfer connected = trueor connected = falsewhen the user logs in and logs out of the user.

---

Question:

My question is, what is the best way to track which sessions are active / connected / registered in my application? Will this be conveyed in these model properties?

Is there a standard way to track sessions for all users? I do not want this to be a stubborn question that is against the rules, but there must be a technical way to keep track of sessions! What would be best for this?

---

Tests:

So, I can be more specific, I put it to the test, and I forgot inside my handlebars template. I can only access the properties of this mongodb user model.

<div class="row">

    {{#if user.connected}}
        {{#each user.connected}}
            <li>{{this}}</li>
        {{/each}}
    {{/if}}

</div>

The above obviously does not work because the data is transmitted when the route for this page is completed.

res.render('profile', { user : req.user });

So, I stick connected: true, connected: falseit’s easy, it works and makes sense to me.

Clarified Question:

, , , handlebars. admin = true, .

, . , , mongoDB? , -

AppUser.find({ connected: true }, function (err, user) {
    console.log(user);
    res.render('profile', { user : user });
});

- , . , , "res.render", ?

, res.render('chat', { user : req.user }), , req.user . , .

AppUser.find({}, function (err, users) {
    console.log(users); 
    res.render('profile', { user: req.user, users : users }); 
});

<div class="row">

    {{#each users}}
        {{#if this.connected}}
            <li><b>Connected:</b> {{this.connected}}</li>
            {{#if this.facebook.email}}
                <li><b>Email:</b> {{this.facebook.email}}</li>
            {{else}}
                <li><b>Email:</b> {{this.local.email}}</li>    
            {{/if}}
        {{/if}}
    {{/each}}

</div>
