Configure grunt-bower-task with Sails.js (Bootstrap + jQuery as example)

bower.js

/**
 * Task to pull out specific files from bower packages.
 */
module.exports = function (grunt) {
  grunt.config.set('bower', {
    install: {
      options: {
        layout: function(type, component) {
          return type;
        },
        targetDir: './assets',
        install: true,
        cleanTargetDir: false,
        cleanBowerDir: false
      }
    }
  });

  grunt.loadNpmTasks('grunt-bower-task');
};

bower.json

{
  "name": "sails-bower",
  "dependencies": {
    "jquery": "^2.2.0",
    "bootstrap": "^3.3.6"
  },
  "exportsOverride": {
    "bootstrap": {
      "styles": "dist/css/*.min.css",
      "fonts": "dist/fonts/*",
      "js/dependencies": "dist/js/bootstrap.min.js"
    },
    "jquery": {
      "js/dependencies": "dist/jquery.min.js"
    }
  }
}

default.js

module.exports = function (grunt) {
  grunt.registerTask('default', ['bower:install', 'compileAssets', 'linkAssets',  'watch']);
};

pipeline.js

// CSS files to inject in order
var cssFilesToInject = [
  'styles/bootstrap.min.css',
  'styles/bootstrap-theme.min.css',
  'styles/**/*.css'
];
// Client-side javascript files to inject in order
var jsFilesToInject = [
  
  // Load sails.io before everything else
  'js/dependencies/sails.io.js',
  
  // Dependencies like jQuery, or Angular are brought in here
  'js/dependencies/jquery.min.js',
  'js/dependencies/bootstrap.min.js',
  'js/dependencies/**/*.js',

  // All of the rest of your client-side js files
  // will be injected here in no particular order.
  'js/**/*.js'
];

prod.js

module.exports = function(grunt) {
  grunt.registerTask('prod', [
    'bower:install',
    'compileAssets',
    'concat',
    'uglify',
    'cssmin',
    'sails-linker:prodJs',
    'sails-linker:prodStyles',
    'sails-linker:devTpl',
    'sails-linker:prodJsJade',
    'sails-linker:prodStylesJade',
    'sails-linker:devTplJade'
  ]);
};

The files should go in the following places (GitHub gist doesn't allow path in filenames):
bower.json
tasks/config/bower.js
tasks/register/default.js
tasks/register/prod.js
tasks/pipeline.js

Don't forget to install grunt-bower-task as a dev dependency using:
npm install grunt-bower-task --save-dev
