Meteor.call('article_type') is async

[tlxfif]

how to use
Meteor.call(‘fun_name’) is sync ?
code

Template.article.helpers({
 article_type(){
   return Meteor.call('article_type')
 }
})

console.log(Meteor.call(‘article_type’)) is undefined

[robfallows]

Template.article.onCreated(function articleOnCreated() {
  this.articleType = new ReactiveVar();
  Meteor.call('article_type', (err, res) => {
    if (err) {
      // handle error
    } else {
      this.articleType.set(res);
    }
});

Template.article.helpers({
  article_type() {
    return Template.instance().articleType.get();
  }
});

You will need to meteor add reactive-var and import { ReactiveVar } from 'meteor/reactive-var'; if you haven’t already done so.
