Use the return value of a Meteor method in a template helper.

MeteorMethodInTemplateHelper.js

if(Meteor.isClient){
  
  // set Session variable in method callback
  Meteor.call('myMeteorMethod', "foo", function(error, result){
    Session.set('myMethodResult', result);
  });
  
  // use reactive Session variable in helper
  Template.myTemplate.helpers({
    myHelper: function(){
      return Session.get('myMethodResult'); // "bar"
    }
  });
  
}

if(Meteor.isServer){
  
  Meteor.method({
    myMeteorMethod: function(argument){
      return "bar";
    }
  });
  
}

Here's a package that does this really well: https://atmospherejs.com/simple/reactive-method

@ecwyne thanks 👍

There is an error in the line 19, it must be Meteor.methods

I have similar code in my project but the result is always undefined. There's no error as I have a check for that and everything is working properly. But for some reason the result is undefined. Thoughts on why?

Is there a way to do this with reactive variables, or some template level scope?

How do you access the session on the template?

Thanks for the recommendation to try https://atmospherejs.com/simple/reactive-method @ecwyne, it works really well. The rest of you guys really should try it as well.
