Simple AngularJS application: Showing error in Gruntfile.js

$ grunt connect:development:keepalive

ERROR:

Running "connect:development:keepalive" (connect) task

Warning: undefined is not a function Use --force to continue.

Aborted due to warnings.

I am presently learning AngularJS from the book Professional AngularJS (wrox) and here's a basic code from the book:

app/index.html

<!DOCTYPE HTML>
<html ng-app="Workflow">
    <head>
        <title>Chapter Two</title>
        <link rel="stylesheet" href="main.css" />
    </head>
    <body ng-controller="ToolsCtrl">
        <h1>Workflow tools from this chapter:</h1>
        <ul>
            <li ng-repeat="tool in tools">{{tool}}</li>
        </ul>

        <script src="bower_components/angular/angular.js"></script>
        <script src="app.js"></script>
    </body>
</html>

app/main.less

html,
body {
  h1 {
    color: steelblue;
  }

app/app.js

'use strict';

angular.module('Workflow', [])
.controller('ToolsCtrl', function($scope) {
        $scope.tools = [
            'Bower',
            'Grunt',
            'Yeoman'
        ];
    });

Gruntfile.js

module.exports = function(grunt) {
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),

        connect: {
            options: {
                port: 9000,
                open: true,
                livereload: 35729,
                hostname: 'localhost'
            },

            development: {
                options: {
                    middleware: function(connect) {
                        return [
                            connect.static('app')
                        ];
                    }
                }
            }
        },

        less: {
            development: {
                files: {
                    'app/main.css': 'app/main.less'
                }
            }
        }
    });

    require('load-grunt-tasks')(grunt);

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

.bowerrc

{
  "directory": "app/bower_components"
}

These are all the codes provided by the book as is, for this application. Also, as the book asked, I ran these commands on the root folder from the terminal:

sudo npm install -g bower

sudo npm install -g grunt-cli

sudo npm install --save-dev grunt

sudo npm install --save-dev load-grunt-tasks

sudo npm install --save-dev grunt-contrib-connect

sudo npm install --save-dev grunt-contrib-jshint

sudo npm install --save-dev grunt-contrib-less

sudo npm install --save-dev grunt-contrib-watch

sudo npm install -g less

lessc app/main.less > app/main.css

grunt less

I had to use sudo because, otherwise it was throwing error:

Please try running this command again as root/Administrator.

According to the book, if I run grunt connect:development:keepalive from my terminal, then, my browser should fire up with the application running. But is giving me the error as I mentioned above.

Please help me with the situation as I have no idea what wrong am I doing. This is why I included all the code. I am very new to these tools and technologies, and I am not even sure if I should follow this book to learn AngularJS.

Thank you.

EDIT:

Since I am using the WebStorm IDE, it is showing me a problem in the Gruntfile.js in the line connect.static('app'). It says Unresolved function or method static() when I hover the mouse over it.

it is correct that the problem is in the Gruntfile.js in the line connect.static('app')

According to the forum from the website for the book "static" is no longer a part of Connect module and you will need to run npm install serve-static. after that declare a variable above your grunt.intConfig line in your Gruntfile.js like so...

var serveStatic = require('serve-static');

then change your middleware function to look like this

middleware: function(connect) {
            return [
              serveStatic('app')

hope this helps. It helped me solve it
