Module Description


Grunt task for converting JSON files to AngularJS values.

This is a fork of [karma-ng-json2js-preprocessor] (

see my gulp version [gulp-ng-json2js] (

I figured that we had no need to convert data on every karma test run, rather we make it into a grunt task that we run when required.

Getting Started

This plugin requires Grunt ~0.4.5

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, you may install this plugin with this command:

npm install grunt-ng-json2js --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:


The "ng_json2js" task


In your project's Gruntfile, add a section named ng_json2js to the data object passed into grunt.initConfig().

  ng_json2js: {
    options: {
            // strip this from the file path
             stripPrefix: 'test/fixture/',

             // prepend this to the
             prependPrefix: 'served/'
    files: [


For instance this test/fixture/data.json ...

    prop: val

... with the configuration given above will be converted into:

angular.module('served/data.json', []).value('servedData', {
    prop: 'val'

Inject json fixture into your test case:

describe('me', function(){

    it('should not fail', function() {
        var testFixture;
        inject(function (_servedData_) {
            testFixture = _servedData_;

            prop: 'val'



In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
