Organize your Gruntfile by feature

Adds grunt.mergeConfig(...), which replaces grunt.initConfig(...), and enables you to organize your Gruntfile by feature, rather than by task.

Example:

Gruntfile.js

module.exports = function(grunt) {

  require('grunt-config-merge')(grunt);



  // Default options:
  grunt.mergeConfig({
    concat: { options: { process: true } },
    watch: { options: { atBegin: true, livereload: true } }
  });



  // JavaScripts:
  grunt.registerTask('build-js', [ 'concat:JS', 'jshint' ]);
  grunt.mergeConfig({
    concat: { 'JS': { files: allJS } },
    jshint: { 'JS': { files: allJS } },
    watch: { 'JS': { files: allJS, tasks: [ 'build-js' ] } }
  });



  // CSS:
  grunt.registerTask('build-css', [ 'concat:CSS' ]);
  grunt.mergeConfig({
    concat: { 'CSS': { files: allCSS } },
    watch: { 'CSS': { files: allCSS, tasks: [ 'build-css' ] } }
  });



  grunt.loadNpmTasks('grunt-contrib-concat');
  grunt.loadNpmTasks('grunt-contrib-jshint');
  grunt.loadNpmTasks('grunt-contrib-watch');

};

And then, easily split your Gruntfile into separate files!

Gruntfile.js:

module.exports = function(grunt) {

  require('grunt-config-merge')(grunt);

  require('./build-defaults.js')(grunt);
  require('./build-js.js')(grunt);
  require('./build-css.js')(grunt);

  grunt.loadNpmTasks('grunt-contrib-concat');
  grunt.loadNpmTasks('grunt-contrib-jshint');
  grunt.loadNpmTasks('grunt-contrib-watch');

};

build-css.js:

module.exports = function(grunt) {

  // CSS:
  grunt.registerTask('build-css', [ 'concat:CSS' ]);
  grunt.mergeConfig({
    concat: { 'CSS': { files: allCSS } },
    watch: { 'CSS': { files: allCSS, tasks: [ 'build-css' ] } }
  });

};

build-js.js:

module.exports = function(grunt) {

  // JavaScripts:
  grunt.registerTask('build-js', [ 'concat:JS', 'jshint' ]);
  grunt.mergeConfig({
    concat: { 'JS': { files: allJS } },
    jshint: { 'JS': { files: allJS } },
    watch: { 'JS': { files: allJS, tasks: [ 'build-js' ] } }
  });

};

Etc...

Installation

Download and install via Node Package Manager:

npm install --save-dev grunt-config-merge

Then add this line near the top of your Gruntfile:

require('grunt-config-merge')(grunt);

And go ahead and start using grunt.mergeConfig instead of grunt.initConfig!
