grunt-merge-objects

Merges two files each with a hierarchical JS key/value object structure. The plugin is specially adapted to object literals specified through AMD define({}). First file is the base object, and subsequent files overrides and extends the base.

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-merge-objects --save-dev

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

grunt.loadNpmTasks('grunt-merge-objects');

The "merge_objects" task

Overview

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

grunt.initConfig({
  merge_objects: {
    options: {
      // functionName: 'define' // Only option and its default value.
    },
    files: {
      // List of files that should be merged, in the order of precedence. Later files override properties in earlier files.
    },
  },
});

Options

options.functionName

Type: String Default value: 'define'

The name of the function wrapping the key/value object literal.

Usage Examples

Properties found in either base.js and extension.js will be copied to a new object literal found in tmp/merged.js, also on sub-property levels. If a property exists in both source files, the value in extension.js will be used.

grunt.initConfig({
    merge_objects: {
      default_options: {
        options: {
        },
        files: {
          'tmp/merged.js': ['test/fixtures/base.js', 'test/fixtures/extension.js']
        }
      }
    }
});

Contributing

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.
