AdvancedSocket
AdvancedSockets aims to help handling connectivity issues from the client side when using ColdFusion WebSocket solution.
Below is a simple example of how to implement. The data attributes defined in the body are the default values and do not have to be set but can be overridden. For more information on how and where they are set refer to the Attributes / Properties section.
<body data-auto-connect="true"
data-name="ws"
data-channels="channelname"
data-debug="true"
data-do-message="doMessage"
data-online-timer="30"
data-offline-timer="5"
data-reconnect-timer=".5"
data-ping-url="ping.cfm">
<div id="status-message" class="hide"></div>
<script src="advanced.js"></script>
<cfwebsocket name ="ws"
onMessage ="AdvancedSocket.onMessage"
onOpen ="AdvancedSocket.onOpen"
onClose ="AdvancedSocket.onClose"
onError ="AdvancedSocket.onError">
<script>
function doMessage(obj){
console.log(obj);
}
</script>
</body>Properties / Attributes
- autoConnect
Controls the auto connect feature of the AdvancedSocket.
Defaults to
truebut can be managed by thedata-auto-connectattribute in the body tag. It also requires a pingURL to be defined. - name
The name of your global websocket variable name.
Defaults to
wsbut can be managed by thedata-nameattribute in the body tag. - channels<br/ >
Comma separated list of channels to subscribe to.
Managed by the
data-channelsattribute in the body tag. - clientID The subscriber ID returned from ColdFusion on a succesful connection. This is used when the autoConnect feature is enabled to make sure that we are still an active subscriber.
- clientInfo This is a key-value object that is passed when creating a connection. By default AdvancedSocket uses a third party request to find out additional geo-based data of the request. This is also used to pass in a username and any additional info you may want to.
- doMessage
Defines the global function to run on a succesful message. Defaults to
doMessage. If the function is not defined or does not exists a log message will be displayed (if debug is enabled). Defaults todoMessagebut can be managed by thedata-do-messageattribute in the body tag. - timer Used for the check AdvancedSocket.checkConnection setTimeout
- pingURL
The URL that will be used to ping if we are still a good connection. Should return a JSON object with a success value of true or false.
Managed by the
data-ping-urlattribute in the body tag. - onlineTimer
The timeout value to ping if autoConnect is enabled while we have a good connection.
Defaults to
30 secondsbut can be managed by thedata-online-timerattribute in the body tag. - offlineTimer
The timeout value to ping if autoConnect is enabled while we have a bad connection.
Defaults to
5 secondsbut can be managed by thedata-offline-timerattribute in the body tag. - reconnectTimer
The timeout value call a reconnect attempt when a
FORCE-RECONNECTvalue is received from the server. Defaults to500msbut can be managed by thedata-reconnect-timerattribute in the body tag. - timerCount The timeout value that is used on reconnect calls. It is automally updated to either the online or offline value based on current state.
- debug
Boolean value to display log messages.
Defaults to
falsebut can be managed by thedata-debugattribute in the body tag. - statusLabel
The status document element defined by an id of status-message.
Defaults to
status-messagebut can be managed by thedata-status-labelattribute in the body tag.
Functions
- init Sets up all required EventListeners to handle window connection events (connectionerror, goodconnection, requireconnection, offline, online). Sets up the timerCount to the onlineCount and then request the checkConnection() function.
- checkConnection Sets up timer and request first ping() call if autoConnect is enabled.
- fireEvent Creates and dispatches custom events.
- ping Polls request to the server to check if connection is still valid.
- onMessage
Handles messages returned. On
welcome, authenticate and/or subscribemessages it auto fires the AdvancedSocket.connected() function. OnFORCE-RECONNECTmessages fires the AdvancedSocket.forceReconnect() funciton based on the reconnectCount. On a regular messages passes to the Global Function that will handle your message. - onOpen Fired onced the connection is open. If authentication is required, it calls the authenticate() WS function if not passes to the AdvancedSocket.getIPInfo() function, which is the last step before subscribing.
- onClose Fired on connection close
- onError Fired on connection errors
- getIPInfo Makes a request to ip-api.com to request Geo Based IP data. On response or if jQuery is not available it will call AdvancedSocket.connectWS(), the final step which handles all connections.
- connectWS Loops thru your defined channels and calls the WS subscribe() function.
- forceReconnect
Fired when a
FORCE-RECONNECTmessage is received. Calls the WS closeConnection() and openConnection() functions which in turn when the socket is open again fires the AdvancedSocket.onOpen() function. - setTimer Handles setting the timer that fires off the check connection event using window.setTimeout
- doLog Outputs console logs if debug is set to true. This can be defined with the body data-debug attribute.
- disconnected :metal: (overwrite to customize) Fired when a socket is disconnected. Updates the status label.
- connecting :metal: (overwrite to customize) Fired when the socket is connecting. Updates the status label.
- connected :metal: (overwrite to customize) Fired when the socket is connected. Updates the status label.
