EDIT: upon further reflection I believe my question is about grunt-contrib-concat rather than sass.
I have a folder of sass files one of which is called colors.scss
//neutrals
$white: #fff;
$light-gray: #eee;
$gray: #9f9f9f;
$slate: #59595A;
$charcoal: #404041;
$gold: #FFD34E;
//define non-neutral colors by use. These are what would change if our app was whitelabeled.
$bright-accent-color: tint(#FF4849, 0%);
$muted-accent-color: $bright-accent-color;
$dark-accent-color: $bright-accent-color;
$note-color: #FFFAD5;
$bright-warning-color: black; // will this be used in new scheme?
$muted-warning-color: tint(#DB9E36, 20%);
$dark-warning-color: $charcoal;
$light-background-color: #f3f6f9;
$primary-nav-color: #172740; // dark blue
$secondary-nav-color: #263D59; // blue
I would like to produce a dozen sets of compiled css files, of which I would swap out the colors.css file for each compiled set. I'm trying to figure out how to incorporate this into my gruntfile without producing seperate tasks for each one. I would like one task that looks in folder called colors that in turn contains all of the colors.scss files and then for each one does a compilation and puts that compiled set of css files in a folder with the same name as the colors.scss file. The problem is I have no idea where to start. I'm using grunt-contrib-sass currently and I'm able to produce one set of files. My gruntfile looks like this:
sass: {
dist: {
options: {
style: 'expanded'
},
files: {
'dist/main.css': 'app/css/main.scss'
}
}
},
which works fine for compiling one set, but I want to iterate over the colors files and produce one set for each file found. is this possible? where should I start?
Think I got it. I edited my gruntfile with the following modules: sass, concat, and copy.
In summary, I concat the specific brand scss file to the main scss file and then copy all of the support files to a sass folder in the dist directory. Then I run sass on the concat'd files and output the final css files to the dist css folder.
Heres the configuration:
module.exports = function(grunt) {
'use strict';
var sassFiles = [];
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.loadNpmTasks('grunt-contrib-concat');
grunt.loadNpmTasks('grunt-contrib-copy');
grunt.registerTask('default', ['concat', 'copy:sass', 'sass']);
grunt.initConfig({
concat: (function(){
var concat = {
options: {
sourceMap: true
}
};
var files = [];
grunt.file.recurse('app/css/brands/', function(abspath, rootdir, subdir, filename){
files.push(filename);
});
sassFiles = files;
files.forEach(file => {
concat[file] = {
src: [
'app/css/brands/'+file,
'app/css/main.scss'
],
dest: 'dist/css/sass/'+file
};
});
return concat;
}()),
sass: {
dist: {
options: {
style: 'expanded'
},
files: (function(){
var fileObject = {};
sassFiles.forEach(file => {
var filename = file.split('.')[0];
fileObject['dist/css/'+filename+'.css'] =
'dist/css/sass/'+file;
});
return fileObject;
}())
}
},
copy: {
sass: {
files: [
{ expand: true, cwd: 'app/css', src: '**', dest: 'dist/css/sass/' }
]
}
}
});
};

I am trying to minify an angularjs application using grunt and terser. I first used uglifiy-es but then read that it has some issues. So I tried terser. But the output does not give me minified files.
The gruntfile.js
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
//grunt task configuration will go here
ngAnnotate: {
options: {
singleQuotes: true
},
app: {
files: {
'./public/min-safe/js/_config_min.js': ['./controllers/_config.js'],
'./public/min-safe/js/ctrl_accountingdashboard.js': ['./controllers/ctrl_accountingdashboard.js'],
}
}
},
concat: {
js: { //target
src: ['./public/min/app.js', './public/min-safe/js/*.js'],
dest: './public/min/app.js'
}
},
terser: {
options: {},
files: {
'./public/min/app.js': ['./public/min/app.js'],
},
}
});
//load grunt tasks
grunt.loadNpmTasks('grunt-contrib-concat');
grunt.loadNpmTasks('grunt-terser');
grunt.loadNpmTasks('grunt-ng-annotate');
//register grunt default task
grunt.registerTask('default', ['ngAnnotate', 'concat', 'terser']);
}
I had the same problem. According to the documentation, this should work but it didn't for me. Wrapping the "files" setting in a custom target works for me:
terser: {
options: {},
main: {
files: {
'./public/min/app.js': ['./public/min/app.js'],
}
}
}
To add to #Tim's great answer:
Here is an example that allows to run grunt-terser with path / file wildcard patterns (globbing) – which it does not support out of the box.
Please note the helper properties _src and _dest in the terser config which are not read by grunt-terser itself but by the task terser_all. This task expands the globbing pattern(s) in _src and builds the real config in the files property. When done it runs terser with that updated config.
module.exports = function (grunt) {
grunt.initConfig({
terser: {
dist: {
options: {
compress: {
drop_console: true // remove console.log, console.info, ...
}
},
files: {
// FILLED through terser_all task below!
// Examples config:
// "dist/example.js": [ "path/to/files/example.js" ]
// "dist/example_joined.js": [ "path/to/files/*.js" ]
},
// -----
// HELPER PROPERTIES to build the files prop (see above) in the terser_all task below.
_src: [
"path/to/files/*.js"
],
_dest: "dist/"
}
}
});
grunt.registerTask('terser_all', function () {
// work on this target in terser config
var terser_target_name = "dist";
// read the terser config
var terser_config = grunt.config.get('terser') || {};
var terser_target_config = terser_config[terser_target_name] || {};
// get the destination dir
var destDir = terser_target_config._dest;
// loop through all source files and create an entry in the terser config for each of it
var files = grunt.file.expand(terser_target_config._src);
for (const [i, file] of files.entries()) {
grunt.log.writeln(file);
// add this file to the terser config as: dest_file: src_file
terser_target_config.files[destDir + file] = file;
}
// show new config on CLI
grunt.log.writeflags(terser_target_config);
// write back config and run task
grunt.config.set('terser', terser_config);
grunt.task.run('terser');
});
grunt.loadNpmTasks('grunt-terser');
grunt.registerTask('build', ['terser_all']);
grunt.registerTask('default', ['build']);
};
Just a note:
If you try to "disable" some options by renaming this disables the whole process. At least this was my result with grunt-terser. I was left with the original js file.
{
mangleX: {
reserved: [/* ... */]
}
}
I have a Sailsjs project, and it comes with Grunt built in. Here is what tasks/register/prod.js looks like:
module.exports = function(grunt) {
grunt.registerTask('prod', [
'compileAssets',
//'concat',
'uglify',
'cssmin',
'sails-linker:prodJs',
'sails-linker:prodStyles',
//'sails-linker:devTpl',
//'sails-linker:prodJsJade',
//'sails-linker:prodStylesJade',
//'sails-linker:devTplJade'
]);
};
and here is my attempt to get Grunt to minify files separately tasks/config/cssmin.js:
module.exports = function(grunt) {
grunt.config.set('cssmin', {
dist: {
src: 'assets/css/test.css',
dest: '.tmp/public/min/test.min.css'
}
});
grunt.config.set('cssmin', {
dist: {
src: 'assets/css/main.css',
dest: '.tmp/public/min/main.min.css'
}
});
grunt.loadNpmTasks('grunt-contrib-cssmin');
};
This doesn't work correctly, it only gives me main.min.css (minified) but not test.min.css.
"dist" is not a static part of the syntax, it's the name of the target. You can have as many targets as you want, but you can't have two with the same name.
grunt.config.set('cssmin', {
test: {
src: 'assets/css/test.css',
dest: '.tmp/public/min/test.min.css'
},
main: {
src: 'assets/css/main.css',
dest: '.tmp/public/min/main.min.css'
}
});
Running "cssmin" executes both targets, "cssmin:test" runs the first one and "cssmin:main" runs the second.
The second time you set the value for the cssmin task you are overwriting your previous value, thus you are only returned main.min.css.
To minify multiple separate files with cssmin you would only set grunt.config once and it would look like this:
module.exports = function(grunt) {
grunt.config.set('cssmin', {
dist: {
src: 'assets/css/test.css',
dest: '.tmp/public/min/test.min.css'
},
dist2: {
src: 'assets/css/main.css',
dest: '.tmp/public/min/main.min.css'
}
});
grunt.loadNpmTasks('grunt-contrib-cssmin');
};
I'm working on a Node.js website and I'm using Grunt to concat and minify my CSS and JS files. However, after running the grunt command I'm getting the error message:

If anything I would have thought jQuery would be the one that's getting concatenated multiple times but it's not. Any suggestions what I might be doing wrong?
EDIT: Here's my upgraded grunt file with all 3rd party libraries listed in the concat.src.

Your issue seems to be in concate.js.src
src: ["public/lib/**/jquery.js", "public/lib/**/*.js", "public/js/cts.js"]
This will have your files added multiple times as there might some files common among the paths mentioned in src.
You should probably move all your vendor files like jquery out of the public directory and put in a different one, say vendor.
Your src should then look something like
src: ["vendor/**/*.js", "public/**/*.js"]
As you see now there are no common files among these two paths.
Also its a good practice to always have 3rd party code outside your app directory as a sibling folder and not inside it.
EDIT:
Ah! I see whats your problem. You want to have jquery first among the other vendor files.
public/lib/**/jquery.js and public/lib/**/*.js together might be causing files added twice.
Try this
src: ["public/lib/jquery/jquery.js", "public/lib/**/*.js", "!public/lib/jquery/jquery.js", public/js/cts.js"]
Put the full path of jquery first public/lib/jquery/jquery.js and then the !public/lib/jquery/jquery.js should prevent jquery being added again as part of public/lib/**/*.js
Got the above pattern from here http://gruntjs.com/configuring-tasks#globbing-patterns
If this still doesn't work, then another option is to add all paths in the src array individually. If you have a requirejs config just copy the paths from there, as jquery might not be the only dependency issue you face in future.
I am trying to concatenate a set of .less files into a big .less file, and then have it processed into a big .css file using Grunt's grunt-contrib-less module.
module.exports = function(grunt) {
require('load-grunt-tasks')(grunt);
grunt.initConfig({
concurrent: {
target1: ['concat:lesscss'],
target2: ['less']
},
concat: {
lesscss: {
files: {
'server/static/css/big.less':
['server/static/css/commons-reset-and-core.css',
'server/static/css/base.less',
'server/static/css/ads.less',
'server/static/css/ext.less']
}
}
},
less: {
files: {
'server/static/css/big.css':
'server/static/css/big.less'
}
}
});
grunt.registerTask('default', ['concurrent:target1', 'concurrent:target2']);
};
The big.less is created properly, but the big.css file is not. Yet, Grunt returns
Done, without errors.
What am I doing wrong?
Did you try to wrap it as here:
less: {
development: {
files: {
'server/static/css/big.css': 'server/static/css/big.less'
}
}
},
I think that's required
I'm new to Grunt and I'm lost in all it's option.
I'm trying to do two things :
Minify all my js files into one each time I change one of them
Process a specific scss file when one of my scss file is changed
Here is the current Gruntfile.js I got :
module.exports = function (grunt) {
grunt.initConfig({
// define source files and their destinations
uglify: {
files: {
src: 'js/*.js', // source files mask
dest: 'jsm/', // destination folder
expand: true, // allow dynamic building
flatten: true, // remove all unnecessary nesting
ext: '.min.js' // replace .js to .min.js
}
},
watch: {
js: { files: 'js/*.js', tasks: [ 'uglify' ] },
}
});
// load plugins
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-uglify');
// register at least this one task
grunt.registerTask('default', [ 'uglify' ]);
};
How could I achieve this?
Use the grunt-contrib-concat
grunt.initConfig({
concat: {
dist: {
src: ['files/**.min.js'],
dest: 'project.js',
},
}
});
You should wrap all you files in an anonymous function and define variables using var so you do not get variable conflicts between files.
(function(){
// foo has function scope
var foo = 3;
console.log(foo);
// FOO is a global variable and
// can be accessed between files
window.FOO = 3;
console.log(FOO);
}).call()
