I'm running a pretty straightforward workflow with Grunt, operating inside MAMP. I'm using a watch task to trigger a Sass task, which runs two sub-tasks (placing expanded and compressed stylesheets in different directories), and minifying/concatenating JavaScript files. The Sass task works without issue, but the Watch task will not see any JavaScript file changes to trigger the Uglify task. Here's my Grunt.js file
module.exports = function(grunt){
grunt.initConfig({
pkg : grunt.file.readJSON('package.json'),
//Sass task
sass:{
dev: {
options: {
style: 'expanded',
sourcemap: 'none'
},
files: {
//Destination, Source
'human-readable/style-expanded.css': 'sass/style.scss',
'human-readable/bootstrap-min.css': 'sass/bootstrap.scss'
}
},
prod:{
options:{
style: 'compressed',
sourcemap: 'none'
},
files:{
//Destination, Source
'style.css': 'sass/style.scss',
'css/bootstrap.min.css': 'sass/bootstrap.scss'
}
}
},
//Uglify task
uglify:{
options:{
mangle: false,
screwIE8: true
},
my_target:{
files:{
//Destination, Source
'js/main.min.js': ['human-readable/main.js','js/bootstrap.min.js']
}
}
},
//Watch task
watch: {
css: {
files: '**/*.scss',
tasks: ['sass']
},
scripts: {
files: '**/*.js',
tasks: ['uglify']
}
}
});
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default', ['watch']);
}
Ideas?
may be you are trying to watch two things at the same time, that might be the problem, try the grunt-concurrent module, it allows you to run grunt tasks concurrently / in parallel:
grunt.loadNpmTasks('grunt-concurrent');
grunt.initConfig({
...
concurrent: {
tasks: ['watch:css', 'watch:script']
}
...
grunt.registerTask('default', ['concurrent']);
...

I have a pretty basic setup with sass, watch and uglify but for some reason I can't get watch to detect when a js file is saved. It works fine for SCSS/CSS (compiles and reloads.) If I run 'grunt uglify' it bundles my JS files, and if watch is running (in another console instance) it will detect it and trigger the reload.
I've tried lots of combinations and I have a feeling it's something really dumb I'm doing/not doing but I'm just not seeing it.
my gruntfile.js:
module.exports = function(grunt) {
grunt.registerTask('default', ['sass', 'uglify']);
grunt.initConfig({
sass: {
dist: {
options: {
style: 'expanded'
},
files: { 'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/css/main.css': 'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/css/main.scss' }
}
},
uglify: {
my_target: {
files: {
'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/js/site.js': [
'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/lib/jquery/dist/jquery.js',
'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/lib/*.js'
]
}
}
},
watch: {
options: {
livereload: 35729,
},
html: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/Views/*.cshtml'],
},
sass: {
options: {
livereload: false
},
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/css/*.scss'],
tasks: ['sass']
},
css: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/css/main.css'],
tasks: []
},
scripts: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/js/site.js'],
tasks: ['uglify']
}
}
});
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.loadNpmTasks('grunt-contrib-uglify');
};
Look at your watch config:
scripts: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/js/site.js'],
tasks: ['uglify']
}
You are only watching for a single js files changes called site.js. To watch all your sources use this config:
scripts: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/lib/*.js'],
tasks: ['uglify']
}
Use the same pattern as in the uglify config. I assumed you are not going to modify jquery itself.
So i am trying to set up my first grunt application, but i am struggling with the watch task.
When I run the task watch looks like it is working when i change my sass files, but the css files are not updated, so it looks like it is not compiling.
I am wondering if i need to install something else, for me this is all new... and i am not sure if I understand, because it looks very simple but I just cant make it work.
So here is my code
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
watch:{
sass:{
options: {
livereload: true
},
files:['sass/**/*.scss'],
task:['sass']
},
css: {
files: ['css/*.css'],
tasks: []
}
},
sass: {
dist: {
files: [{
expand: true,
cwd: 'sass',
src: ['*.scss', '*.sass'],
dest: 'css/',
ext: '.css'
}]
}
}
});
grunt.loadNpmTasks('grunt-sass');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default', ['sass']);
};
I think you want your livereload to be on the css files instead of scss. As it is the compiled file that you want to be reloaded and not the preprocessed (scss) file.
Example
watch:{
sass:{
files:['sass/**/*.scss'],
task:['sass']
},
css: {
options: {
livereload: true
},
files: ['css/*.css']
}
}
OWWWWW....
I just found the problem... it should have been "tasks" not "task", i wasted sooo much time, on finding this little thingy!
I try to added the Sass task to my grunt process using the grunt-contrib-sass plugin but when i run it he create the css files but this file is empty
This is my Gruntfile.js :
module.exports = function(grunt){
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
sass: {
dist: {
options: {
style:'expanded',
trace: true
},
files: {
'main.css':'sass/app.scss'
}
}
},
watch: {
css: {
files: '**/*.scss',
tasks: ['sass']
}
}
});
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default', ['watch']);
};
When i start the command "grunt" i have this :
Running "watch" task Waiting..... File "sass\app.scss"
changed Running "sass:dist" task (and nothing)
I have :
Ruby 2.1.5 [x64-mingw32]
SASS : 3.4.10
Grunt : newest version
Thanks !
Could you try changing this:
watch: {
css:
files: '**/*.scss',
tasks: ['sass']
}
}
To this:
watch: {
css:
files: '/**/*.scss',
tasks: ['sass']
}
}
To make sure it watches from the root of the project
Curious about whether there’s a way to use both Autoprefixer and Compass in Grunt without having to specify a different output path for each task.
I currently have my .scss files in a folder named source. The compass task compiles these into a folder named build. I want to then run Autoprefixer without having to specify another different output path (i.e. still be in the build directory).
Is it not possible to run Autoprefixer on a compass compiled CSS file without specifying a different output path? Is it possible to run both at the same time perhaps?
Here’s the section of my gruntfile it relates to if it’s of any help. What I run in terminal is grunt watch:
compass: {
options: {
sassDir: 'style/source',
cssDir: 'style/build',
outputStyle: 'expanded',
}
},
watch: {
css: {
files: ['style/source/**/*.scss'],
tasks: ['compass'],
options: {
spawn: false,
}
}
},
Refs:
https://github.com/nDmitry/grunt-autoprefixer
https://github.com/gruntjs/grunt-contrib-compass
If you do not specify an output location for Autoprefixer, it will just use the input location and overwrite the files. Here’s the updated section of the gruntfile if it’s of help to anyone:
autoprefixer: {
css: {
src: 'style/build/**.css',
}
},
watch: {
options: {
livereload: true,
},
css: {
files: ['style/source/**/*.scss'],
tasks: ['compass', 'autoprefixer:css'],
options: {
spawn: false,
}
}
}
You may also want to add map: true to the autoprefixer call.
Here is a working copy for your goal :
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
autoprefixer: {
css: {
src: 'css/*.css',
options: {
map: true
}
}
},
compass: {
css: {
options: {
config: 'config.rb'
}
}
},
watch: {
css: {
files: '**/*.scss',
tasks: ['compass:css', 'autoprefixer:css'],
options: {
interrupt: true
}
}
}
});
grunt.loadNpmTasks('grunt-autoprefixer');
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default', ['watch']);
};
I have recently discovered grunt as it is used within an opensource project I have started to work on. Having not worked with grunt before I am struggling to see how it works, or in my case doesn't.
The grunt file is supplied by the project and I assume it works for everyone else. I have installed grunt and the necessary grunt modules have all installed in the "Node_modules" directory.
When running the grunt file the first process performs a number of concatenations and this seems to work fine. The concatenated files are created.
All of the other steps do not seem to execute. The files they are intended to create are not created. There is no error message displayed on the console when grunt is executed.
I'm stumped - anyone have any clues what might be the problem.
The grunt file is :

The output from the console is as follows :
Running "jshint:globals" (jshint) task
>> 0 files lint free.
Running "concat:dist" (concat) task
File "chrome/js/requester.js" created.
Running "concat:requester_html" (concat) task
File "chrome/requester.html" created.
Running "concat:requester_tester" (concat) task
File "chrome/tester.html" created.
Done, without errors.
Given that the tasks are defined like this:
grunt.registerTask('default', ['jshint', 'concat']);
grunt.registerTask('package', ['concat', 'handlebars', 'sass', 'compress']);
the output you show is what you'd expect if you are running grunt without a task name. It runs the jshint and concat tasks.
If you want to run the tasks associated with package, then you have to run grunt package to run those tasks.
It looks like I did not understand "tasks" within grunt.
Instead of executing "grunt" which runs the "default" tasks, I had to execute "grunt package" which runs the tasks that I was interested in.
As Louis said, you have to specify the right task to run.
But you can also create or modify the tasks you have in order to make it simpler. In your example you may include package in the default task. Because concat task is already executed inside package, you may just replace it in the default task:
grunt.registerTask('default', ['jshint', 'package']);
grunt.registerTask('package', ['concat', 'handlebars', 'sass', 'compress']);
and, in order to build your site, just type
grunt
both jshint and package tasks will be executed
