Question

Let\'s say I have a todo app, and I want to make sure that every user that registers has at least one todo to start with, something like \"First todo to cross off!\", how wo

You can piggyback onto functions that are called by Meteor by wrapping them. I'm also using the accounts-ui and accounts-password packages and I use Underscore's _.wrap method to redefine the loginWithPassword function. Underscore is included in Meteor by default.

I use something like this for logging in:

Meteor.loginWithPassword = _.wrap(Meteor.loginWithPassword, function(login) {

  // Store the original arguments
  var args = _.toArray(arguments).slice(1),
      user = args[0],
      pass = args[1],
      origCallback = args[2];

  // Create a new callback function
  // Could also be defined elsewhere outside of this wrapped function
  var newCallback = function() { console.info('logged in'); }

  // Now call the original login function with
  // the original user, pass plus the new callback
  login(user, pass, newCallback);

});

In this specific case, the code above would go in your client code somewhere.

For Accounts.createUser, it might look something like this (also somewhere in client code):

Accounts.createUser = _.wrap(Accounts.createUser, function(createUser) {

  // Store the original arguments
  var args = _.toArray(arguments).slice(1),
      user = args[0],
      origCallback = args[1];

  // Create a new callback function
  // Could also be defined elsewhere outside of this wrapped function
  // This is called on the client
  var newCallback = function(err) {
    if (err) {
      console.error(err);
    } else {
      console.info('success');
    }
  };

  // Now call the original create user function with
  // the original user object plus the new callback
  createUser(user, newCallback);

});

Hope that's helpful.
