Using Angular and Meteor together: reactive wrapper

angular-meteor-autorun.js

// bind a Meteor reactive computation to the current scope
angular.module('myApp')
.factory('autorun', function() {
  return function(scope, fn) {
    // wrapping around Deps.autorun
    var comp = Deps.autorun(function(c) {
      fn(c);
      
      // this is run immediately for the first call
      // but after that, we need to $apply to start Angular digest
      if (!c.firstRun) setTimeout(function() {
        // wrap $apply in setTimeout to avoid conflict with
        // other digest cycles
        scope.$apply();
      }, 0);
    });

    // stop autorun when scope is destroyed
    scope.$on('$destroy', function() {
      comp.stop();
    });

    // return autorun object so that it can be stopped manually
    return comp;
  };
});
