    <p>You could use a Meteor Session variable as a reactive data source so the template automatically re-renders (<a href="http://docs.meteor.com/#session_set" rel="nofollow">http://docs.meteor.com/#session_set</a>). Try this:-</p> <pre><code>if (Meteor.is_client) { // Use 'greeting' Session variable as a reactive data source Session.set('greeting', 0); Template.hello.greeting = function () { return "Welcome to test: " + Session.get('greeting'); }; Meteor.setInterval(function() { Session.set('greeting', Session.get('greeting') + 1); }, 1000); } if (Meteor.is_server) { Meteor.startup(function () { // code to run on server at startup }); } </code></pre> <p><strong>Updated:</strong> To show hooking into <code>streams</code> package. Example works but use at your own peril</p> <pre><code>if (Meteor.is_client) { // Use client from stream package sc = new Meteor._Stream('/sockjs'); sc.on('message', function(payload) { var msg = JSON.parse(payload); // Set session variable so template reacts Session.set('greeting', JSON.stringify(msg.data)); }); // Use 'greeting' Session variable as a reactive data source Template.hello.greeting = function () { return Session.get('greeting'); }; } if (Meteor.is_server) { // Use server from stream package ss = new Meteor._StreamServer(); // register handler for socket connection ss.register(function (socket) { var data = {socket: socket.id, connected: new Date()} var msg = {msg: 'data', data: data}; // Send message to all sockets _.each(ss.all_sockets(), function(socket) { socket.send(JSON.stringify(msg)); }) }); } </code></pre>

    1. COThanks, but I would like this to be synced between clients. Updated at the same time with the same message.

    2. COAh ok I see what you mean. The `Meteor.Publish(..)` and `Meteor.Subscribe(..)` functions are solely for `Collections` which is why you couldn't find anything in the docs. You could either use a `Collection` to sync data between client and server although I agree that seems quite clunky if you only want to post an arbitrary message to clients. Another 'hack' you could try is hooking into the underlying `SockJS` library or the `streams` package. The `streams` approach is going to be simpler but also riskier as the methods havent been exposed to us and their implementation is liable to change.

    3. COI've added a basic example of illustrating how to hack into the `streams` package included with `Meteor`. It shows the connection time of the latest socket opened with the server. If another client connects all clients are updated with the latest socket time.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
