This is probably an affect of my inefficient setup and not a problem with grunt/livereload.
Here's my watch test in my grunfile.js:
watch: {
images: {
files: ['images/**/*.{png,jpg,gif}', 'images/*.{png,jpg,gif}'],
tasks: ['imagemin'],
options: {
spawn: false
}
},
js: {
files: ['js/*.js','js/**/*.js'],
tasks: ['jshint'],
options: {
spawn: false
}
},
svgs: {
files: ['images/*.svg','images/**/*.svg'],
task: ['svgmin'],
options: {
span: false
}
},
scss: {
files: ['sass/*.scss', 'sass/**/*.scss'],
tasks: ['sass','autoprefixer'],
sourceComments: 'normal',
options: {
nospawn: true,
livereload: true
}
}
},
This will recompile my SASS and the reload the page, but it takes 5-6 seconds to complete the CSS compilation, then it does a full page refresh, instead of just reloading the CSS file that changed.
So my questions are this:
How do I keep it from taking so long to compile the SASS and refresh the page, or am I just being to picky, and this is an inherit part of grunt?
How keep if from reloading the entire page, and just reload the CSS file that changed from my SASS compilation?
Check my other answer: Fastest way to compile SCSS (Compass) + refresh the browser?
grunt-contrib-sass uses Ruby sass which is very slow, it has nothing to do with grunt itself.
Use grunt-sass instead, it uses libsass which is lighting fast c implementation of sass.
Read this article:
http://benfrain.com/lightning-fast-sass-compiling-with-libsass-node-sass-and-grunt-sass/
The best solution is to move from grunt-contrib-sass to grunt-sass, but if you don't have much time to fix this, i think, you should move your 'autoprefixer' task from watch section to deploy section.
scss: {
files: ['sass/*.scss', 'sass/**/*.scss'],
tasks: ['sass',
sourceComments: 'normal',
options: {
nospawn: true,
livereload: true
}
}
In my project this trick help me, because 'autoprefixer' task works very slowly
Or you could use a live reloader tool, like fast-live-reload, in combination with the ruby sass compiler.
Note that they offer their own watcher that is very fast (e.g. for compass run: compass watch).

I have lots of different partials and sass files to generate 11 individual website specific style sheets so if I make a changes in a partial that is being used in all 11 style sheets then I have to wait for grunt to compile all these before I can refresh my browser and see the change, one workaround I have is to use the specify option and change the site ID depending on which site I am working on -
compass: {
dev: {
options: {
sassDir: "assets/sass",
specify: "assets/sass/site_##.scss",
cssDir: "assets/styles",
outputStyle: "expanded",
noLineComments: false,
sourcemap: true
}
}
},
watch: {
css: {
files: 'assets/sass/**/*',
tasks: 'compass',
},
},
Is there a way I could make this dynamic in the watch task, i.e. using an ID appended to the body or something?
My partials -
_reset
_grid
_layout
_variables
_mixins
_brand1
_brand2
_brand3
_summer
_winter
_site_1_specific
_site_2_specific
_site_3_specific
_site_4_specific
_site_5_specific
_site_6_specific
_site_7_specific
_site_7_specific
_site_9_specific
_site_10_specific
_site_11_specific
I then have 11 SCSS files importing a combination of the above partials to make the final style sheets.
You can use grunt-newer, that helps you to execute the compass task only in the file that is changed:
https://github.com/tschaub/grunt-newer
npm install grunt-newer --save-dev
grunt.loadNpmTasks('grunt-newer');
Then, you have to change your watch task:
watch: {
css: {
files: '<%= tui.sass %>/**/*',
tasks: ['newer:compass']
},
},
Hope it helps.

I'm trying to install 'modular-scale' (https://github.com/Team-Sass/modular-scale) via my Gruntfile but I can't get it to work.
Note that I don't use a config.rb, I want to require the plugin using Grunt via grunt-contrib-compass.
I thought it was as simple as adding this to my Gruntfile (after the grunt.initConfig({ etc):
compass: {
dist: {
options: {
require: ['modular-scale'], // This line here
sassDir: 'setup',
cssDir: 'css'
}
}
},
watch: {
css: {
files: '**/*.scss',
tasks: ['compass']
}
}
The watch task is absolutely fine. The problem is that if I use one of the SASS variables that are part of the 'modular-scale' plugin, I'll get an error thrown up, suggesting that the 'modular-scale' isn't actually being required.
Am I missing something here?
You no longer need Compass or a config.rb file to use modular-scale.
My livereload is "working" in that it live reloads the page when a file is changed, but only if I modify the file directly. If the file is generated through the grunt stylus or jade compiler, nothing happens.
When I look at grunt with verbose turned on, the Live reloading root.css... line appears only if I save root.css directly. If root.css is modified through the stylus compiler, the line does not appear. It's as if watch doesn't detect the file has been changed if it's changed through a compiler. This same issue occurs with jade as well.
Here's my stylus task (trimmed):
stylus: {
options: {
compress: false,
use: [
require('autoprefixer-stylus')
]
},
src: [
'app/styl/**/*.styl'
],
dest: 'build/css/root.css'
}
And here's my watch task (trimmed):
livereload: {
options: {
livereload: 1337,
},
files: 'build/**/*'
},
stylus: {
files: [
'app/styl/**/*.styl',
],
tasks: ['stylus:dev']
},
I really hope I'm just doing something stupid. I can't find any problems similar to this one.
EDIT:
Just in case this helps, I discovered that by changing my grunt task from running ['clean','jade:dev', 'stylus:dev', 'connect:dev', 'watch'] to only running ['connect:dev', 'watch'], livereload works as intended once, then never again. (Modifying the css directly still works though.)
EDIT 2:
I was able to fix this by adding livereload to each specific task in watch, like so:
livereload: {
options: {
livereload: 1337,
},
files: 'build/**/*'
},
stylus: {
files: [
'app/styl/**/*.styl',
],
tasks: ['stylus:dev'],
options: {
livereload: 1337
}
},
As to why this works, I have no idea. If anyone can shed some light on this, it'd be much appreciated. Though to be honest, I don't know why I didn't try this earlier.
GruntJS newbie here. I currently have my gruntfile.js using the watch task to look for changes to any .js files in my js/components/ folder and uglify those scripts into a single script.js file.
The issue that I'm having is that these changes cause a full page reload.
Is it possible to only reload the script.js file without also reloading the HTML/CSS? The effect I'm after is the same effect I'm currently getting with SASS/CSS files like so:
watch : {
options: { livereload: true },
sass: {
options: {
livereload: false
},
files: ['css/sass/*.scss'],
tasks: ['compass:dev']
},
css: {
files: ['css/*.css']
}
}
This reloads only my CSS without reloading the entire page, which makes for a much smoother workflow. Is it possible to do the same for JS? If not, why not? My current JS workflow configuration looks like this:
grunt.initConfig({
uglify: {
my_target: {
files: {
'js/script.js' : ['js/components/*.js']
}
}
},
watch : {
options: { livereload: true },
scripts: {
files: ['js/components/*.js'],
tasks: ['uglify']
}
}
});
After reading around I finally wound up on the livereload.js Github page. Under the developer's rundown of the project's current status, "Live JS reloading" is the one remaining to-do item. So it's a planned feature, but not yet implemented. The last commit on the project was 7 months back, so I'm not sure when/if we can anticipate this update.
I want to use watch mode in my development environment. It works fine with single less file. But I have so many less files which are imported to app.less. My app.less looks
#import "variables";
#import "mixins";
It seems I can not use watch mode in this setting. Is there any other ways?
Upd. This syntax is for old grunt versions so it should not be used.
You need to use LiveReload app for this. Or maybe another software that can reload page with LiveReload browser extension (maybe Sublime Text editor with a plugin).
Possible setup is Node.js with Grunt which has grunt-contrib-less and grunt-reload modules installed.
Your grunt.js config should look like this:
module.exports = function(grunt) {
grunt.initConfig({
// Start LiveReload server
reload: {
port: 35729,
liveReload: {}
},
// Simple css compilation
less: {
src: 'less/app.less',
dest: 'css/app.css'
},
// Reload files on change
watch: {
less: {
files: ['less/*.less'],
tasks: 'less'
},
reload: {
files: ['*.html',
'css/app.css',
'js/*.js'],
tasks: 'reload'
}
}
});
// Third party modules
grunt.loadNpmTasks('grunt-reload');
grunt.loadNpmTasks('grunt-contrib-less');
// Register default task
grunt.registerTask('default', 'less');
};
Then you need to run
$ grunt watch:less
and
$ grunt watch:reload
in two separate terminal windows.
I'm totally agree with this comment
Refresh less css which has other imported less files without page load .
Thanks, thevasya.
But there's no need to start several terminals.
watch: {
less: {
files: ['less/*.less'],
tasks: 'less'
},
reload: {
files: ['*.html',
'css/app.css',
'js/*.js'],
tasks: 'reload'
}
}
after that you can start watching by
$ grunt watch
and that's it. If you change any less file, it will start only less task.
P.S.: This answer was updated for proper work with grunt 0.4.
