voidale:helpers-everywhere

A simple, package to make it easy use template helpers at template events, onCreated, onRendered, onDestroyed or even plain JavaScript code.

• Finds global helpers registered using "Template.registerHelper"
• Finds template instance helpers "Template.ANY.helpers({})"

helperName: string

template (optional): template instance object or a template name string.

returns: helper function, so you can use .call(), .apply(), .bind() as you need it.

Global Registered Helper:

Template.registerHelpers("demoHelper", function () {
  console.log('hello');
});

Use anywhere (notice the "()" at the end required to execute the function) Can also use .call()...

Meteor.helpers("demoHelper")();

Template Instance Helpers

Template.ANY.helpers({
  demoHelper: function () {
    console.log('hello');
  }
});

Template.ANY.onRendered({
  var helper = Meteor.helpers("demoHelper", this)();
});
