karma-coffee-preprocessor

> Preprocessor to compile CoffeeScript on the fly.

Installation

This plugin ships with Karma by default, so you don't need to install it, it should just work ;-)

The easiest way is to keep karma-coffee-preprocessor as a devDependency in your package.json.
``json
{
"devDependencies": {
"karma": "~0.10",
"karma-coffee-preprocessor": "~0.1"
}
}
`

You can simple do it by:
`bash
npm install karma-coffee-preprocessor --save-dev
`

Configuration


Following code shows the default configuration...
`js
// karma.conf.js
module.exports = function(config) {
config.set({
preprocessors: {
'*/.coffee': ['coffee']
},

coffeePreprocessor: {
// options passed to the coffee compiler
options: {
bare: true,
sourceMap: false
},
// transforming the filenames
transformPath: function(path) {
return path.replace(/\.js$/, '.coffee');
}
}
});
};
`

If you set the sourceMap coffee compiler option to true` then the generated source map will be inlined as a data-uri.
