Helpers

[mamzellejuu]

Hi,

do you have example how helpers need to be formated to be functionnal ?

I don't have any examples handy - what trouble are you having?

Find the solution, need to name the file the name of the helper name

Hi there,

I'm also having troubles with helpers. Everything runs fine until I try to include them.

I have a very simple helper, howdy.js

Handlebars.registerHelper("howdy", function(){
  return "howdy";
});

My grunt file looks like

    'compile-handlebars': {
      dist: {
        template: '<%= config.src %>/templates/**/*.hbs',
        templateData: '<%= config.src %>/data/**/*.json',
        partials: '<%= config.src %>/partials/**/*.hbs',
        helpers: '<%= config.src %>/helpers/**/*.js',
        output: '<%= config.dist %>/*.html',
      },
    },

When I run Grunt, I get the error, Running "compile-handlebars:dist" (compile-handlebars) task Warning: Handlebars is not defined Use --force to continue."

Everything runs fine if I remove the helpers option in the grunt file, but then I can't use helpers. Any ideas?

Hey @ryan-ludwig!

Seems like your handlebars helper isn't including handlebars.

By default, you only need to export a function matching the function signature of a handlebars helper.

that means rather than

Handlebars.registerHelper("howdy", function(){
  return "howdy";
});

you can have a file named howdy.js, that looks like

module.exports =  function() {
  return "howdy";
};

alternatively , requireing handlebars in your helper file should work,

var Handlebars = require('handlebars');

Handlebars.registerHelper("howdy", function(){
  return "howdy";
});

though I honestly haven't tried that previously, and can't check right now (on a mobile).
