Could I check "is ready" to wait the result like pub/sub?

[thearabbit]

I create the Meteor.method() to generate reports, so I want to show the spinner or any loading... when the serve is running.
Could I check "is ready" to wait the result like pub/sub?
Please example for me.

Interesting point - could you show me more code ? If you're using the PromiseHelper, I just pushed an update that lets you pass an additional loading text, in addition to the function to wrap. If that's not your use case, I'm not sure I can help - post some code and let's see though :)

Template.foo.helpers({
  report: PromiseHelper(function(){ return Meteor.call(method, args); }, "loading...")
});

// Server
Meteor.methods({
    add: function () {
        Meteor._sleepForMs(1000);
        return 'Welcome to Promise Call';
    }

// Client
<template name="myTpl">
   {{#if myValue}}
      {{myValue}}
   {{else}}
      {{> spinner}}
   {{/if}}

Template.myTpl.helpers({
   myValue: PromiseHelper(function(){
      return Meteor.call('add');
   })
})
</template>

Could I use loading with spinner template?
PromiseHelper(function(){ return Meteor.call(method, args); }, Template.spinner)

I think you could do so like this: Blaze.toHTML(Template.spinner)

Template.myTpl.helpers({
   myValue: PromiseHelper(function(){
      return Meteor.call('add');
   }, Blaze.toHTML(Template.spinner))
})

Let me know if that works for you - I'm not sure if that functionality is something I'd take on internally, but I'd document it as a valid use case if it works!

It don't work. It show [object object].

Sorry, I could not reproduce this - if you have a more full example I'd love to see it. Thanks for all the great questions.
