Need an event handler / way to check when the user logs in

The issue is hacky solutions need to be found for when the user logs in/or out.

E.g when using the accounts-ui, when the user logs in an event to redirect the page (via meteorite meteor-router package) to the correct content.

However if the url is copy pasted to another browser window the accounts page will load (because meteor.autorun is used to run on the page load, as well as when the reactive Meteor.userId changes.

Thanks for bringing this up, @Tarangp, this is a good point. Users who use the raw login APIs (loginWithPassword, etc) can do this using the callback argument, but users who use accounts-ui have no good way to specify an action to take on login completion. We should add either an event or hook of some sort that fires whenever the user logs in or out, or perhaps some additional options to accounts-ui.

In the mean time, I think a viable workaround is something like:

var oldUserId = undefined;

Meteor.autorun(function() {
  var newUserId = Meteor.userId();
  if (oldUserId === null && newUserId) {
    console.log('The user logged in');
  } else if (newUserId === null && oldUserId) {
    console.log('The user logged out');
  } 
  oldUserId = Meteor.userId();
});

We do not use GitHub to track feature requests (other than for Blaze). The core team's current roadmap is at https://roadmap.meteor.com/. Discussions about features that users desire are great topics for the meteor-talk mailing list, where the community can help come up with solutions that don't require core changes.

Fortunately, there's a workaround as defined above.
