Meteor - Cancelling a Server Method from the Client

I\'m performing a database count through a server method. Users can select how they want the count to be performed and then invoke the method.

Answer 1

Cancelling an already-made method call to server from client is not possible.

But if your method are called multiple times in a short interval, and you only care about the last call's result. You could use debounce to delay execution for some times. This will help reduce unnecessary calls to server.

Answer 2

More of a work around, but if you had a reactive variable (could be an entry in the DB) that is a status of the method, and in the method itself, you check for that flag every chance you get for the status.

{
    _id: "some id for the method", running: true
}

Pseudocode for method

Meteor.methods({
    method: (_id) => {
        status = getStatusForId(_id);
        while(status) {
            status = getStatusForId(_id);
        }
    }
});

Then to stop it, you just update that flag to be false and the method will stop as soon as it can.
