0.8.0 • Public • Published


Precompile ember templates in grunt using only ember-template-compiler.js.

Updating Guide

Getting Started

If you haven't used grunt before, be sure to check out the Getting Started guide, as it explains how to create a gruntfile as well as install and use grunt plugins. Once you're familiar with that process, install this plugin with this command:

npm install grunt-ember-handlebars --save-dev

Handlebars task

Run this task with the grunt ember_handlebars command.

This task is a multi task so any targets, files and options should be specified according to the multi task documentation.

Version 0.3.x of this plugin is compatible with Grunt 0.4.x. Version 0.1.x of this plugin is compatible with Grunt 0.3.x.



Type: String Default: linefeed + linefeed

Concatenated files will be joined on this string.


Type: String Default: 'Ember.TEMPLATES'

The namespace in which the precompiled templates will be assigned. Use dot notation (e.g. App.Templates) for nested namespaces.


options: {
  namespace: 'MyApp.Templates'


Type: Boolean Default: true

Determine if preprocessed template functions will be wrapped in Ember.Handlebars.template function.


Type: function

This option accepts a function which takes one argument (the template filepath) and returns a string which will be used as the key for the precompiled template object. The example below stores all templates on the default Ember.TEMPLATES namespace in capital letters.

options: {
  processName: function(filename) {
    return filename.toUpperCase();


Type: function

This option accepts a function which takes one argument (the partial filepath) and returns a string which will be used as the key for the precompiled partial object when it is registered in Handlebars.partials. The example below stores all partials using only the actual filename instead of the full path.

options: {
  processPartialName: function(filePath) { // input:  templates/_header.hbs
    var pieces = filePath.split("/");
    return pieces[pieces.length - 1]; // output: _header.hbs

Note: If processPartialName is not provided as an option the default assumes that partials will be stored by stripping trailing underscore characters and filename extensions. For example, the path templates/_header.hbs will become header and can be referenced in other templates as {{> header}}.


Type: Regexp Default: /^_/

This option accepts a regex that defines the prefix character that is used to identify Handlebars partial files.

// assumes partial files would be prefixed with "par_" ie: "par_header.hbs"
options: {
  partialRegex: /^par_/

Usage Examples

ember_handlebars: {
  compile: {
    options: {
      namespace: "MyApp.TEMPLATES"
    files: {
      "path/to/result.js": "path/to/source.hbs",
      "path/to/another.js": ["path/to/sources/*.hbs", "path/to/more/*.hbs"]


In lieu of a formal styleguide, take care to maintain the existing coding style.
