How to deal with an uncaught exception error in Meteor?

How do I listen to an uncaught exception error in meteor?

The errors are of course specific to the cause, so please can you provide a pseudo style code/explanation that states the concept of handling this error.

An example use case:

A user clicks 'logout' but there is an uncaught exception and the user does not get logged out and so the connection to the server remains open.

You can use the callbacks, they usually provide a reason parameter. E.g

Meteor.call("some_random_non_existent_method", function(err, result) {
    if(err) return alert(err.reason)
});

Most meteor callbacks have a error param. With the logout its Meteor.logout(function(err) { ... })

You should be able to catch most types of errors like this. If you want to capture all errors you can use try..catch. Everything in the try block will try to run until it throws an error. You can catch this and provide feedback to the user.

try {
    //This will throw an error
    this.run_something.go_make_error()
}catch(e) {
    alert("There was an error running this");
}
