Firehouse socket.io to update web-clients
208
A tiny socket using SocketIo to update a general map when something changes in the application
You must install Node (and socketio if you have any trouble using this)
For the server, after cd to this project's folder you should run:
node socketio.js
And that will start the mini server
In your application you must have the core.js (utilities/core.js) file and it must be available when you want to call any functions
For example you can make a file like this that manages the Updates
//javascript
var Updater = ( function () {
var socket = io('http://localhost:8085') //check the port if you changed it in the configuration
, timeout = 1500
, listenToUpdates = function () {
socket.on('update interventions', function (data) {
var message = 'New updates'
showMessage(message)
setTimeout(refreshPage, timeout)
});
}
, emitEvent = function (event, incomingMessage) {
if (event == 'new update') socket.emit(event, { message: incomingMessage })
}
, showMessage = function (message) {
var alertDiv = document.querySelector('[rel="alerts"]')
alertDiv.className = 'alert alert-warning'
alertDiv.innerHTML = message
}
, refreshPage = function () {
window.location.reload()
}
return {
update : listenToUpdates
, emitEvent : emitEvent
}
} () )
And then call them from your views:
// When you want to let the server knows that something happened, I usually do this after an ajax request.
InterventionUpdater.emitEvent('new update')
<!-- This goes where you want to catch the advices from the server -->
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
Updater.update();
});
</script>
PD: this is super beta and made for a specific project, probably you should edit the socketio.js file in order to make this work correctly
