How can I put global template helpers together in Meteor?

Question

I have several global template helpers

Template.registerHelper("termSuffix",function(){});

Template.registerHelper("subjects",function(){});

Template.registerHelper("date",function(){});
...

I tried this (like normal/local template helpers)

Template.registerHelper({
      termSuffix:function(){},
      subjects:function(){},
      date:function(){}
});

But it throws Exception from Tracker recompute function:Error: No such function: termSuffix

This syntax is not supported for global helpers. Docs Code

If you think it's a compelling enough change to the library, you could submit a pull request.

Meanwhile, you can wrap the Template.registerHelper function with your own:

function registerGlobalHelpers(helpers){
    _.chain(helpers)
     .each( (fn, name) => { Template.registerHelper(name, fn); })
     .value();
  }

or defined without chaining in underscorejs:

function registerGlobalHelpers(helpers){
  _.each(helpers, (fn, name) => { Template.registerHelper(name, fn); });
  }

Then use it like this:

registerGlobalHelpers({
      termSuffix:function(){},
      subjects:function(){},
      date:function(){}
})
