    karma-source-map-support

    Greenkeeper badge

    Karma plugin for inline sourcemap support.

    Motivation

    When loading Browserify bundles with inline source maps (via karma-browserify), the stack traces in Chrome don't mention the original modules. This plugin uses source-map-support to improve the situation.

    Use

    Install the plugin with npm:

    npm install karma-source-map-support
    

    Configure Karma to load the plugin as a framework:

    module.exports = function(config) {
      config.set({
        frameworks: ['source-map-support']
        // additional settings here ...
      });
    };

    Example

    The config settings below are a complete example using Mocha and Browserify with source map support:

    module.exports = function(config) {
      config.set({
        frameworks: ['browserify', 'source-map-support', 'mocha'],
        files: [
          'src/**/*.test.js'
        ],
        preprocessors: {
          'src/**/*.test.js': ['browserify']
        },
        browsers: ['PhantomJS'],
        singleRun: false,
        browserify: {
          debug: true // include inline source maps
        }
      });
    };
