karma-ember-preprocessor

Preprocessor to compile handlebars templates for ember.js on the fly

For more information on Karma see the homepage.

Requires Karma 0.9+

To use this with karma, first you will need to install it with npm

npm install karma-ember-preprocessor

Next you need to create a configuration file using karma init

module.exports = function(karma) {
    karma.set({
        basePath: 'js',

        files: [
          "vendor/jquery/jquery.min.js",
          "vendor/handlebars/handlebars.js",
          "vendor/ember/ember.js",
          "app.js",
          "tests/*.js",
          "templates/*.handlebars"
        ],

        logLevel: karma.LOG_ERROR,
        browsers: ['PhantomJS'],
        singleRun: true,
        autoWatch: false,

        frameworks: ["qunit"],

        plugins: [
            'karma-qunit',
            'karma-chrome-launcher',
            'karma-ember-preprocessor',
            'karma-phantomjs-launcher'
        ],

        preprocessors: {
            "**/*.handlebars": 'ember'
        }
    });
};

In case you want to use your custom Ember template compiler, you can specify path for it in the preprocessor configuration

module.exports = function(karma) {
    karma.set({

        ...

        emberPreprocessor: {
            compilerPath: 'bower_components/ember/ember-template-compiler.js'
        }
    });
};

It is also possible to specify a transform function to be used for the template name.

module.exports = function(karma) {
        karma.set({
            ...
            emberPreprocessor: {
                nameTransform: function(templateName) {
                    // your transform function code
                    return transformedName;
                }
            }
        });
    };

Processed templates will made available in Ember.TEMPLATES. For example:

templates/parent.hbs // => Ember.TEMPLATES['parent']
templates/parent/child.hbs // => Ember.TEMPLATES['parent/child']
templates/parent/child/index.hbs // => Ember.TEMPLATES['parent/child/index']
