How to update each X seconds a widget?

Fez Vrasta

Is there some example?

I'd like to update the content of my widget each X seconds.

You mean client-side? You can use default javascript setInterval http://www.w3schools.com/jsref/met_win_setinterval.asp
If you need server-side update, you can use cron or smth like this

I display data from a remote request, and I'd like to update it client-side each X seconds. But I can't perform the update using client-side JS, I need Node.js.

So I was wondering if there is a way to tell to a widget to reload the data from its node.js source.

I recommend sockets.

This is the way I do it. There's probably better ways, I'm a noob.

I put a listener on my client js,

socket.on('whatever', function(data) {
    // Update any widgets using data.
});

and set a timer in my server code and do:

SocketIO.in("online_users").emit('whatever', {somevalue: getWhateverValue()});

Is SocketIO alredy inited by NodeBB or do I have to include it and initialize it?

Also, what is the best way to include client-side JS in a widget?

@Fez-Vrasta You have to include it. e.g. var SocketIO = require('./socket.io');

I'm not sure if there is an option for per widget client js. I put it in my main client.js in my plugin.json.
