I have a bunch of various css from plugins and separate style sheets I am using, and I am trying to build a task that will combine and minify all of them. Right now I'm trying to do this with cssmin, I am not sure if I am on the right path, as this is my first time trying this, but here is what I am trying.
cssmin: {
target: {
files: {
'css/output.css': ['css/*.css', 'css/*.min.css']
},
files: [{
expand: true,
cwd: 'css',
src: ['css/output.css'],
dest: 'build/css',
ext: '.min.css'
}]
}
}
The idea is that it will take all css and min.css files in my css folder and combine them into 1 output.css then minify that build/css as a min.css file. I am not too sure if this is how this is suppose to work but this is my first attempt in trying so. The basic idea is combine and minify everything into 1 file in the bottom of my tasks (after I have auto prefixed and used uncss to strip bootstrap). I would appreciate any guidance, is this the right direction with this? This doesn't seem to work correctly, so would appreciate any help.
Thanks for reading!
I am not sure... but this works for me, and only have to include cssmin task in my grunt.registerTask line of code. It minifies all my autoprefixed .css, except the already minified versions and combine them into one big minified stylesheet. Hope it helps ^^
cssmin: {
minify: {
files: [{
expand: true,
cwd: 'src/styles',
src: ['**/*.css', '!**/*.min.css'],
dest: 'public/assets/styles',
ext: '.min.css'
}]
},
options: {
shorthandCompacting: false,
roundingPrecision: -1
},
combine: {
files: {
'public/assets/styles/style.css': ['!public/assets/styles/**/*.min.css', 'public/assets/styles/**/*.css']
}
}
}
minify task is not necessary. When you concatenate several files, cssmin minifies the content automatically.
cssmin: {
options: {
shorthandCompacting: false,
roundingPrecision: -1
},
combine: {
files: {
'css/output.min.css': ['css/*.css', '!css/*.min.css']
}
}
}

I'm using imagemin with Grunt and it works as expected with PNGs/JPGs, but not with SVGs.
When I add an SVG into my project, Grunt says:
>> File "../public/microsite/src/img/Sketch.svg" added.
Running "imagemin:dynamic" (imagemin) task
Minified 0 images (saved 0 B)
Is this simply because it can't optimise them any further, or because it's not trying to at all? Even if an SVG can't be optimised, which I doubt is the case, I'd still like it imagemin to place it in the dist folder.
This is my config:
imagemin: {
dynamic: {
options: {
optimizationLevel: 3,
svgoPlugins: [{ removeViewBox: false }]
},
files: [{
expand: true,
cwd: '../public/microsite/src/img/',
src: ['*.{png, jpg, svg}'],
dest: '../public/microsite/build/img/'
}]
}
}
I figured out the spaces in the src object were invalid. I removed them, which allowed all image files to be minified. src: ['*.*'] also works.
We are trying to compile our sass files to css files, however we want to compile each individual sass file into an individual css file (one-to-one).
For example our product_view.scss should have a product_view.css.
However all configurations we have tried create one css file for everything called styles.css in our "out/css" folder.
sass: {
dist: {
options: {
compass: true,
style: 'expanded'
},
files: [{
expand: true,
cwd: '<%= pkg.src %>/assets/sass',
src: ['*.scss'],
dest: '<%= pkg.src %>/assets/media/out/css',
ext: '.css'
}]
},
},
I use grunt-contrib-compass (Compass) to compile my SASS, which has some nice extras. For example, compass includes a reset utility you can use by using
#import 'compass/reset';
But disregarding that, compass also outputs every file individually (as long as it does not start with _ which are files that can be included but won't be compiled by themselves). Here is the setup I use in my gruntfile:
compass: {
'default': {
options: {
sassDir: "css/sass/",
cssDir: "css/",
outputStyle: "compressed"
}
}
}
I cannot seem to find an easy way to copy all the files from Polymer to using grunt-bower-task.
grunt.initConfig({
bower: {
install: {
options: {
targetDir: 'wwwroot/lib',
layout: 'byComponent',
install: true,
copy: true,
verbose: true,
cleanTargetDir: false,
bowerOptions: {}
}
}
}
I understand that only the main files defined inside each element's bower.json file get copied over. I am also aware that I could put a exportsOverride section in my own bower.json to include more files like this -
"exportsOverride": {
"*": {
"": "*.*",
"demo": "demo/*.*",
"test": "test/*.*"
}
}
But this doesn't cover all cases as some elements have more sub-folders than just demo and test. Do I have to manually look them all up and add their paths to the exportsOverride, or there's an easy way that I've overlooked?
hate to provide a sample of a fail....
FWIW recently , i had very similar issue ... worked it and failed
what i did is abandon the attempt to flatten everything out in the "dist" tag for a first polymer project. Rather i just ran minify/ugly on one or two elements leaving the HTTP2 type file structure ( deep and many many, dirs/files. )
// the process belo NG . Manual edit needed on "polymer-min.html" go end and chg the js file name
copy: {
main: {
files: [
// includes files within path
{expand: true, src: ['*html'], dest: 'dest/', filter: 'isFile'},
// includes files within path and its sub-directories
{expand: true, src: ['js/**', 'images/**' ,'css/**' ,'elements/**' ,'bower_components/**'], dest: 'dest/'},
{ src: ['tmp/csp/build-csp.html'], dest: 'dest/bower_components/cast-button-polymer/cast-button-polymer-min.html',
filter: 'isFile',
options: {
process: function (content, srcpath) {
return content.replace(/build-csp.js/g,"cast-button-polymer-min.js");
},
},
},
{ src: ['tmp/csp/build-csp-min.js'], dest: 'dest/bower_components/cast-button-polymer/cast-button-polymer-min.js', filter: 'isFile'},
],
},
},
I have the following setup in Grunt for the concat and minification of my projects css
cssmin: {
options: {
},
concat: {
files: {
'dist/app.css': [
'tmp/*.css',
'app/theme/css/vendors/fontello.css',
'app/theme/js/vendors/revolution/css/settings.css',
'app/theme/css/styles.css',
'app/theme/css/media-queries.css',
'app/app.css'
]
}
},
min: {
files: [{
src: 'dist/app.css',
dest: 'dist/app.css'
}]
}
},
It works fine with the exception that, as far as I can tell its removed the following import statement
#import url("http://fonts.googleapis.com/css?family=Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic");
And all 3rd party css files have relative image paths which are not resolved. I can see cssmin uses clean css which should be able to help handle these issues but after hours of searching and reading the docs I can't any clear examples or doucmentation on how to configure the above to solve this?
I used Ze Rubeus suggestion of moving my font import statement into the HTML instead (a little annoying as it means modifying a 3rd party css file). But I found the option for fixing the css paths which is
rebase: true,
relativeTo: './'
My cssmin configuration now looks like
cssmin: {
options: {
rebase: true,
relativeTo: './'
},
concat: {
files: {
'dist/app.css': [
'tmp/*.css',
'app/theme/css/vendors/fontello.css',
'app/theme/js/vendors/revolution/css/settings.css',
'app/theme/css/styles.css',
'app/theme/css/media-queries.css',
'app/app.css'
]
}
},
min: {
files: [{
src: 'dist/app.css',
dest: 'dist/app.css'
}]
}
}
And everything is working :)
You have to change all you import PATH depend on this directory 'dist/app.css'
And instead of css font import I advice you to use the HTML link like the following
<link href='http://fonts.googleapis.com/css?family=Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic' type='text/css'>
make sure to change all url Path's on these directory's :
'tmp/*.css',
'app/theme/css/vendors/fontello.css',
'app/theme/js/vendors/revolution/css/settings.css',
'app/theme/css/styles.css',
'app/theme/css/media-queries.css',
'app/app.css'
depend on this output 'dist/app.css': because there is no task in gruntjs who correct the import Path in css files for you !
regarding your code the watch task need's to be something like so :
watch: {
css: {
files: ['tmp/*.css',
'app/theme/css/vendors/fontello.css',
'app/theme/js/vendors/revolution/css/settings.css',
'app/theme/css/styles.css',
'app/theme/css/media-queries.css',
'app/app.css'],
tasks: ['concat','cssmin'],
options: { spawn: false }
}
},
And execute this command grunt watch in your terminal to keep automatically tracking for changes in these files and apply these tasks .
I have the following snippet in my Gruntfile.js:
imagemin: {
options: {
optimizationLevel: 7,
cache: false
},
dist: {
files: [{
expand: true,
cwd: 'Assets/img/',
src: ['**/*.{png,jpg,gif}', '!optimised/*.*'],
dest: 'Assets/img/optimised/'
}]
}
}
When I run grunt imagemin the files in /optimised get optimised again, what's the correct pattern to make sure I exclude whatever files I have in my 'optimised' folder?
I've tried the globbing pattern ! that's used to negate a match but can't make it work.
Just found the answer, maybe this might help someone else as I couldn't find anything like it on SO.
src: ['**/*.{png,jpg,gif}', '!optimised/**']
