Grunt not live-reloading Sass/SCSS (NodeJS) - node.js

I am having a little trouble with Grunt, it's compiling my Sass/SCSS files (.scss I am using) but it won't LiveReload. I'm using the 'watch' dependency which integrates the LiveReload functionality.
Watch: https://github.com/gruntjs/grunt-contrib-watch
Sass/SCSS: https://github.com/gruntjs/grunt-contrib-sass
Here's my config below (relevant piece), can anyone advise as to where I'm going wrong? It live reloads for everyother file and folder.
grunt.initConfig({
connect: {
options: {
port: 9000,
hostname: 'localhost'
},
livereload: {
options: {
middleware: function ( connect ) {
return [
mountFolder(connect, 'app'),
lrSnippet
];
}
}
}
},
open: {
server: {
path: 'http://localhost:<%= connect.options.port %>'
}
},
sass: {
app: {
files: {
'./app/css/style.min.css': 'app/css/scss/style.scss'
}
}
},
watch: {
options: {
nospawn: true
},
css: {
files: './app/css/scss/*.scss',
tasks: ['sass'],
options: {
livereload: true,
},
},
livereload: {
options: {
livereload: LIVERELOAD_PORT
},
files: [
'app/{,*/}*.html',
'app/css/{,*/}*.{css,scss,sass}',
'app/js/{,*/}*.js',
'app/img/{,*/}*.{png,jpg,jpeg,gif,webp,svg}'
]
}
}
});

Instead of using the connect middleware, try using something like this in your watch task (coffeescript Gruntfile syntax below):
watch:
livereload:
files: "path/to/generated/css"
options:
livereload: true

WebStorm / grunt debug run throwing EADDRINUSE error

I have a Node/Angular app, developed using the WebStorm IDE. I can run the application fine via WebStorm (Shift + F10). However, any time I try to run in debug mode, I am receiving the EADDRINUSE error:
Running "concurrent:default" (concurrent) task
Verifying property concurrent.default exists in config...OK
Files: [no src] -> default
Options: limit=10, logConcurrentOutput
Error: listen EADDRINUSE :::52387
Here is my gruntfile.js - like I said, WebStorm builds and runs it just fine, until I try to run it in debug mode, where it throws the error:

The problem is caused by the way Grunt spawns child tasks. By default, grunt.util.spawn() inherits main process arguments and starts child process with same options as the main process (--debug-brk=52387), so child process is started on the same debug port as the main process, causing EADDRINUSE. See https://github.com/gruntjs/grunt/issues/1420.
As a workaround, try adding process.execArgv = []; to the top of Gruntfile.js - it should help

Grunt app deployed on Heroku ... and what's next ?... my app doesn't start

I have a basic node app with gruntfile and I had some pains to make the deploy. So I did a new grunt task, did some changes.
The deploy then is fine.
But now when I go to my app. I have a blank page.
It doesn't load the appConfig.app dir.
I probably miss something big I couldn't figure out. I thought grunt connect would do the wire but it seems server.js is waiting something.
NB : I think I don't need Express here.

}
It was a huge and harsh debugging but I finally found out.
It was coming from multiple mistakes and bugs I had :
the node server.js is useless
I invstigated on the grunt connect method and created a production setup
I splitted the grunt serve into a grunt build task and a webconnect task
Then updated package.json file
Very important for heroku : in Gruntfile.js on the connect object :
dist: {
options: {
port:process.env.PORT, #<=== need to have a dynamic port env for Heroku deployment
open: true,
base: '<%= appConf.dist %>'
}
}
here are the grunt tasks added :
// Build the production application
grunt.registerTask('build', 'Compile on dist folder', function () {
grunt.task.run([
'clean:dist',
'ngconstant:production',
'wiredep',
'sass',
'concurrent:dist',
'autoprefixer:dist'
]);
});
// Build the production application
grunt.registerTask('webconnect', 'connect web server', function () {
grunt.task.run([
'connect:dist'
]);
});
then on package.json :
"scripts": {
"postinstall": "bower install && grunt build",
"start": "grunt webconnect"
}

why this error come 'can not read property summary of undefined' when running command grunt filerev_apply?

why I am getting can not read property summary of undefined error while I run grunt filerev_apply or grunt filerev_replace . And when I run grunt.filerev.summary
It shows grunt.filerev.summary is not recognized as internal or external command.
Gruntfile.js

Grunt watch task is not starting until the first output to console

My task configuration works fine but I have annoying issue where the watch task does not start to monitor unless I refresh a page or add a line for console output. So normally I am supposed to get:
Running "watch" task
Waiting...
But I don't get it until some output goes to the console.
Is it a bug?
My config is:
module.exports = function(grunt) {
grunt.initConfig({
concat: {
options: {
separator: '\n\n'
},
dev: {
src: ['ng_app/app.js', 'ng_app/**/*.js'],

How to configure Grunt serve/livereload to combine mustache templates

I'm using Yeoman template to develop a static web site. grunt serve nicely works with the auto reload plugin.
For repeating elements I started to use {{mustache}} partials and it works like a blast. Now I want the auto reload to assemble my page, so I can look at the resulting page when editing one of the mustache files (either a main file or a partial).
I found a grunt task for it, but stitching it together eludes me. My config looks like this:
grunt.initConfig({
sass: {
dev: {
src: ['src/sass/*.sass'],
dest: 'dest/css/index.css',
},
},
watch: {
sass: {
// We watch and compile sass files as normal but don't live reload here
files: ['src/sass/*.sass'],
tasks: ['sass']
},
mustache: {
files: '**/*.mustache',
tasks: ['mustache_render'],
options: {
interrupt: true
},
},
livereload: {
options: { livereload: true },
files: ['dest/**/*']
}
},
mustache_render: {
options: {
{data: 'common-data.json'}
},
your_target: {
files: [
{expand: true,
template: '**/*.mustache',
dest: 'dest/'}
]
}
}
});
I must be missing something since the html files are not updated when I save the file.
You can add the livereload option directly to your mustache target options.
grunt.initConfig({
watch: {
mustache: {
files: '**/*.mustache',
tasks: ['mustache_render'],
options: {
interrupt: true,
livereload: true
},
}
},
mustache_render: {
options: {
{data: 'common-data.json'}
},
main: {
files: [
{expand: true,
template: '**/*.mustache',
dest: 'dest/'}
]
}
}
});
Also, if you're using grunt-contrib-connect to serve your files, don't forget to add the livereload option to it:
connect: {
http: {
options: {
hostname: "*",
port: process.env.PORT || 80,
livereload: true
}
}
}
