Direct to Specific Route when meteor auto refreshes

Question

Im using meteor + Iron Router and I would like to handle (in the onbefore web hook) the case where meteor auto refreshes all connected clients and redirect to the home route ('/').

Is there a flag to determine when a refresh is caused by meteor live updating vs a client triggered refresh?

Answer 1

An auto-refresh triggered by a code change leaves Session variable values in-tact, whereas a client-triggered refresh will reset them all to null. So, if I understand you correctly, you could check for the presence of a Session variable in the Meteor.startup callback on the client and call Route.go('/') if it's null. Example:

if (Meteor.isClient) {
    Meteor.startup(function() {
        if (!Session.get('keyKnownToHaveValue')) {
            Route.go('/');
        }
    });
}
