karma-base64-to-js-preprocessor

Preprocessor for converting base64-encoded files into JavaScript strings.

Installation

Just run:

npm install karma-base64-to-js-preprocessor --save-dev

Configuration

This is the default configuration:

// karma.conf.js
module.exports = function(config) {
  config.set({
    preprocessors: {
      '**/*.exe.base64': ['base64-to-js']
    },
    files: [
      '**/*.exe.base64',
      '*.js'
    ]
  });
};

How does it work ?

This preprocessor converts base64-encoded files into JS strings and publishes them in the global window.__raw__.

For instance the file test.base64:

VGhpcyBpcyBhIHRlc3QuCg==

will be served as test.base64.js:

window.__raw__ = window.__raw__ || {};
window.__raw__['test'] = "This is a test.";
