Redirecting AngularJs requests to index.html from Node/Express for html5mode?

I'm going nuts with this one...

I'm developing a angular app where I used the yeoman angular scafolding.

My server side is node/express and I'm using AngularJs on the client side.

I'm trying to prettify my url with html5mode and from what I've read, you have to use connect-moderewrite to do this, which I've installed.

I followed the instructions and added it to my Grunt file, but I'm getting an invalid token error.

Has anyone used this and can you tell me what I'm doing wrong?

From what I can see you add the code to livereload.

I've followed this tutorial - http://jjt.io/2013/11/16/angular-html5mode-using-yeoman-generator-angular/

My Grunt file looks like this:

 // Define the configuration for all the tasks
grunt.initConfig({

        // Project settings
        yeoman: appConfig,

        // Watches files for changes and runs tasks based on the changed files
        watch: {
            bower: {
                files: ['bower.json'],
                tasks: ['wiredep']
            },
            js: {
                files: ['<%= yeoman.app %>/scripts/{,*/}*.js'],
                tasks: ['newer:jshint:all', 'newer:jscs:all'],
                options: {
                    livereload: '<%= connect.options.livereload %>'
                }
            },
            jsTest: {
                files: ['test/spec/{,*/}*.js'],
                tasks: ['newer:jshint:test', 'newer:jscs:test', 'karma']
            },
            compass: {
                files: ['<%= yeoman.app %>/styles/{,*/}*.{scss,sass}'],
                tasks: ['compass:server', 'postcss:server']
            },
            gruntfile: {
                files: ['Gruntfile.js']
            },
            livereload: {
                options: {
                    livereload: '<%= connect.options.livereload %>'
                },
                files: [
                    '<%= yeoman.app %>/{,*/}*.html',
                    '.tmp/styles/{,*/}*.css',
                    '<%= yeoman.app %>/images/{,*/}*.{png,jpg,jpeg,gif,webp,svg}'
                ]
            }
        },

        // The actual grunt server settings
        connect: {
            options: {
                port: 9000,
                // Change this to '0.0.0.0' to access the server from outside.
                hostname: 'localhost',
                livereload: 35729
            },
            livereload: {
                options: {
                    open: true,
                    middleware: function(connect, options) {
                        var optBase = (typeof options.base === 'string') ? [options.base] : options.base;
                        return [require('connect-modrewrite')(['!(\\..+)$ / [L]'])].concat(
                                optBase.map(function(path) {
                                    return connect.static(path); })),
                            connect.static('.tmp'),
                            connect().use(
                                '/bower_components',
                                connect.static('./bower_components')
                            ),
                            connect().use(
                                '/app/styles',
                                connect.static('./app/styles')
                            ),
                            connect.static(appConfig.app)
                    ];
                }
            }
        },
