My livereload setting.

Gruntfile.js

/*jslint white: true, nomen: true, maxlen: 120, plusplus: true, node: true, */
/*global module:false,  */

'use strict';

module.exports = function(grunt) {

  grunt.initConfig({

    connect: {
      server: {
        options: {
          port: 9001,
          hostname: 'localhost',
          base: '.',
          open: true,
          keepalive: false
        }
      }
    },

    watch: {
      livereload: {
        files: ['*.js', '*.css', '*.html']
      },
      options: {
        livereload: true
      }
    }
  });

  // npm install grunt-contrib-watch --save-dev
  grunt.loadNpmTasks('grunt-contrib-watch');
  // npm install grunt-contrib-connect --save-dev
  grunt.loadNpmTasks('grunt-contrib-connect');

  grunt.registerTask('default', ['connect', 'watch']);
};
