Meteor.js on login event

javascript, meteor

Solution

I don't know if the way you're doing it is the most appropriate but personally do the following on the client side to detect if a user logged in:

Tracker.autorun(function(){
  if(Meteor.userId()){
    //do your stuff
  }
});

Problem

So I'm rather new to the meteor framework and JavaScript in general, but I'm working on a little project using the framework to try and bring myself up to scratch. Basically I'm working on a micro blogging site. At the moment users are able to log in through several services, fb, google etc. And I retrieve their avatars via the service id inserted into the needed url, all this works fine. But I want the user to be able to see their own avatar as soon as they log in which means I need to run some JavaScript right after login is successful. At this point in time I cant find anything on an onLogin style event. And have hacked together a handlebars template to run the code when a user logs in. However this code appears to only run once and if a user logs out and then back in they don't see their avatar anymore. Does anyone know of an event I can use to do this? here is my hacky template ``` {{#if currentUser}} {{> userInput}} {{/if}} ``` here is the js it calls ``` $('#inputAvatar').css('background-image', 'url('+avatarUrl+')'); ``` I would really appreciate the help, I'm sure it's something simple that I've overlooked but I cant seem to figure it out! Thanks, Peter.
