Grunt livereload with node.js application

Not sure if you have solved this question yet, but I have done this by adding my express application as a middleware attached to the 'connect.livereload.options.middleware' option.

However, automatic reloading of server side code doesn't work. For that you could implement a reload friendly server using a simple 'node ./server.js', create a connect middleware that acts as a transparent proxy to your development server, and invoke that within your Gruntfile.js before your standard connect/livereload server starts.

connect: {    options: {        port: 9000,        // change this to '0.0.0.0' to access the server from outside        hostname: 'localhost'    },    livereload: {        options: {            middleware: function (connect) {                return [                    lrSnippet,                    mountFolder(connect, '.tmp'),                    mountFolder(connect, 'app'),                    require('./server') // your server packaged as a nodejs module                ];            }        }    }}

server.js:

var app = express();...// Export your server object.module.exports = app;

My answer is using Gulp that I am more familiar with, instead of Grunt, but I imagine the same approach would work with Grunt as well.

See my repository (and an older one) and my other answer.

Neither any browser extension nor adding any script to your files is needed.

The solution is based on the gulp-livereload and connect-livereload packages working together. First, you start your live reload listener, and pipe into it any file changes (change * to any more specific node-glob to listen to only specific files):

var gulpLivereload = require('gulp-livereload');gulpLivereload.listen();gulp.watch('*', function(file) {  gulp.src(file.path)    .pipe(gulpLivereload());});

Second, you configure your server to use the listener as middleware via connect-livereload:

var connect = require('connect');var connectLivereload = require('connect-livereload');connect()  .use(connectLivereload())  .use(connect.static(__dirname))  .listen(8080);

See the packages for more information on how they work internally.

In the Gruntfile, remove connect:livereload and open from server task.

Add following script in the HTML file

<!-- livereload script --><script type="text/javascript">    document.write('<script src="http://'        + (location.host || 'localhost').split(':')[0]        + ':35729/livereload.js?snipver=1" type="text/javascript"><\/script>')</script>
