When developing with ChatEngine, errors will be reported to let the developer know when things go wrong. By default, errors are emitted both as a $.error and as an Event from the object that is responsible, and bubbled via throw.
Thrown Errors
You'll notice thrown errors because they usually break Javascript execution and log a stack trace within the console.
Errors as Events
You can also subscribe to errors via the $.error Event. If you'd like to subscribe to all ChatEngine errors, try the following:
ChatEngine.on('$.error.*', (payload) => {
console.log(payload);
});
Errors in Production
In a production app, it is not a good idea to throw errors. If a developer wants to suppress errors, supply { 'throwErrors' : false } in the ceConfig used to initialize ChatEngine.
Example Error
Below are the errors thrown when a client tries to access a chat you don't have access to.
let PrivateChat = new ChatEngine.Chat('locked-down-i-dont-have-permissions');
A private chat emits these events:
$.error.presence$.error.publish
ChatEngine emits this event:
$.network.denied
