Any way to append the css and not override it?
app is the default name taken by the webpack
So either change
.sass('resources/assets/sass/app.scss', 'public/css') -> .sass('resources/assets/sass/app.scss', 'public/css/newfile.css')
or
mix.styles(['resources/assets/style.css'], 'public/css/app.css') -> mix.styles(['resources/assets/style.css'], 'public/css/styles.css')
Edit: If you need everything in one file
mix.sass('resources/assets/sass/app.scss', 'public/css/app.css')
mix.styles(['public/css/app.css', 'resources/assets/style.css'], 'public/css/app.css')
Hope this helps
You don't need to change your webpack file.
In addition to importing .sass and .scss files, Sass can import plain old .css files. The only rule is that the import must not explicitly include the .css extension, because that’s used to indicate a plain CSS #import.
Webpack
mix.js('resources/assets/js/app.js', 'public/js')
.sass('resources/assets/sass/app.scss', 'public/css');
Sass (resources/assets/sass/app.scss)
...
#import '../style.css';

I am using Webpack with Encore under Symfony. I have enable SassLoader, uncommenting .enableSassLoader(), and renamed assets/css/app.css into assets/css/app.scss.
I have modified the require in assets/js/app.js from ../css/app.css to ../css/app.scss.
Until now, it works. Style file is compiled in public/build/app.css
BUT I have a lot of parts SCSS files to import (one includes variables, an other ones mixins, an other one the HTML reset etc.).
So when I try to use (for example, I took only one, and I placed it in the same directory than app.scss:
#import "header"
Or
#import "header.scss";
It doesn't work! Neither import works.
I have tried to add, in my app.js:
require('../css/header.scss');
Above the working:
require('../css/app.scss');
Still doesn't work.
I have tried to add, in webpack.config.js:
.addEntry('header', './assets/js/header.js')
EDIT: It was very stupid !
In my imported scss file 'header', I called #extends .wrapper, which didn't existed yet because it was in an other file I had commented! I didn't read error message in my termimal ^^
Thank for your help everybody
Massya92: Have you added .enableSassLoader() in webpack.config.js ?
TL;DR: My question is how to bundle some of my sass files into single sass file?
I've been developing an Angular component library and I package it with ng-packagr. Let's call it #my-lib/ngx-components.
Consumers of my lib will import my components like #my-lib/ngx-components/navbar.
I decided to add theming support to components.
For example, I have a navbar component with default colors (background, text, hover etc.) I want consumers of my library to be able to override these colors with their own theme. That's why I've written a mixin which takes a $theme input and override some css rules as follows (this is a basic version of what I have)
_navbar-theme.sass
#mixin navbar-theme($theme)
$primary-color: map-get($theme, primary-color)
$secondary-color: map-get($theme, secondary-color)
$color: map-get($theme, color)
.navbar
background-color: $primary-color
color: $color
&:hover
background-color: $secondary-color
Each component has its own *-theme.sass file.
I also have global _theming.sass file which imports all of these as follows
_theming.sass
#import './components/navbar/navbar-theme'
#import './components/button/button-theme'
#import './components/dropdown/dropdown-theme'
I want to export this _theming.sass file from my lib, so people can import this file in their own sass file as #import '~#my-lib/ngx-components/theming' and start using all of the mixins available.
If they want to have custom navbar, button etc, they should be able to use those mixins with single import.
I tried to make it look like angular-material theming setup.
At first, I have tried node-sass which is already in my dependencies. But, it tries to build sass into css so it omits mixins in the output file.
Then, I looked at what angular-material has done. They use scss-bundle
I thought "this is exactly what I want." However, it requires scss files, not sass files. It cannot read sass files.
Then, I thought "Okay, I can give up on sass and start using scss. How do I convert all those files to scss without going through them by hand". Then, I found sass-convert. In this question it was said that I can use it within command line. However, when I install sass-convert with npm globally, it didn't give me a command line executable. I think I need Gulp to use it.
I've been avoding to use Gulp from the beginning, because it means another tool to learn and it adds complexity to codebase.
At this point, I feel like "Hal fixing light bulb"
TL;DR: My question is how to bundle some of my sass files into single sass file?
Also, If you can come up with a solution that requires webpack, that's fine too.
Let's through your opinion or questions:
I want to export this _theming.sass file from my lib, so people can
import this file in their own sass file as #import
'~#my-lib/ngx-components/theming' and start using all of the mixins
available. If they want to have custom navbar, button etc, they should
be able to use those mixins with single import.
You need to know, what is your target audience. Mostly people using angular cli for create their app like template scratch.
So you need provide css bundle (people just want import your css) and sass bundle (who want to use your object or your mixin).
I want to export this _theming.sass file from my lib, so people can
import this file in their own sass file as #import
'~#my-lib/ngx-components/theming' and start using all of the mixins
available. If they want to have custom navbar, button etc, they should
be able to use those mixins with single import.
I tried to make it look like angular-material theming setup.
Firstly, you need to know that #angular/material doesn't export sass (they use scss) but they export css thene compiled by scss-bundle (as you mention it) see their code and documentation theme.
I thought "this is exactly what I want." However, it requires scss
files, not sass files. It cannot read sass files.
I would like quote this answer:
Sass is a CSS pre-processor with syntax advancements. Style sheets in
the advanced syntax are processed by the program, and turned into
regular CSS style sheets. However, they do not extend the CSS standard
itself.
It is better you need transfer your code from sass to scss (by yourself), it would not much to do it (I think, I always write scss instead sass file).
Solution:
1. Provide css and sass (scss better)
When you deliver your component libs, You have to provide css and scss. Beacuse angular cli doesn't provide scss loader by default.
Don't use sass file, use scss file see my refer answer on top.
scss-bundle + webpack
Since you have to provide css, you can you webpack shell plugin to bundle scss. Scss have provide cli, if you want to use cli.
2. Structure your scss
Okay, let's take sample from bootstrap#4 module for this case. Bootstrap use structure like this (Documents):
scss
|-- _variables.scss
|-- _mixins.scss
|-- _functions.scss
|-- ...
|-- index.scss
inside index.scss will have like this:
#import 'variables'
#import 'mixins'
#import 'functions'
...
so, this scss you have to deliver beside css. Like bootstrap do, then mixin will available to consumer. Also this good approach when consumer to find scss file in scss folder (easy to pointing which is scss put in).
UPDATE
For bundle to single file you have to create task runner to do it. In your case you want to use webpack, you can create a plugin to do it.
Here example plugin:
scss-bundle-plugin.js
call to you config webpack:
plugins: [
new webpack.NoEmitOnErrorsPlugin(),
new SCSSBundlePlugin({
file: path.join(__dirname, 'src/index.scss')
})
],
To try playground, checkout hello-world-loader then:
# install dependency
npm install
# try play ground
npm run webpack
it will create file _theme.scss at ./dist.
My advice don't use webpack, use task runner instead (gulp or grunt) for this simple case. Webpack too advance and hard to write task.
There is also a widely used package, called scss-bundle.
It is quite simple to use, you just create a config file with all relevant configuration and then run scss-bundle.
This for example will use all scss files, imported in entry.scss and move it to out.scss. All imports will be resolved, except for angular themes in this example, like #import '~#angular/material/theming';.
scss-bundle.config.json:
{
"bundlerOptions": {
"entryFile": "my-project/src/entry.scss",
"outFile": "dist/out.scss",
"rootDir": "my-project/src",
"project": "../../",
"ignoreImports": [
"~#angular/.*"
],
"logLevel": "debug"
}
}
My solution for scss / sass files
I've used small module bundle-scss
It bundles files by file name mask. So you need to pass correct mask like ./src/**/*.theme.scss specify destination file and maybe your custom sort-order
You don't have to create one entry point file with all imports. bundle-scss will get all files by mask analyze all imports and include this files as well
Can we refer sass file instead of css file directly in the index.html?
If it is possible, how does the webpack compile sass into css file? Also, which is the best way to bundle the sass file while building the application?
I am using the following versions:
webpack(3.5.5), angular/cli(1.4.1) and angular4
My folder structure is like this,
src
├--- assets
| ├--- sass
| | ├--- common.scss
| | ├--- base.scss
| | ├--- coustom.scss
| ├--- css
| ├--- common.css
| ├--- base.css
| ├--- coustom.css
|
├--- index.html
├--- .angular-cli.json
First of all browser does not understand scss ot less. so you have to compile then and convert them to css while running in your browser.
As you are using angular cli there is a pretty sumple way to do that and no configuration required.
new cli project
so while generating you project you can pass a flag to tell cli to choose scss instead of css.
ng new projectname --style scss
existing project
If its an existing cli project you can edit .angular-cli.json file to change from css to scss.
first your style need to scss
"styles": [
"/asset/scss/common.scss",
"/asset/scss/base.scss",
"/asset/scss/custom.scss",
"/asset/scss/common.css",
"/asset/scss/base.css",
"/asset/scss/custom.css",
"styles.scss"
],
and the default style is scss
"defaults": {
"styleExt": "scss",
"component": {}
}
For external js libraries you you add a script block and add your scripts there. it will automatically added to your build.
"scripts": [
"../node_modules/jquery/dist/jquery.js"
],
I have tried to follow the instructions at laravel-elixir, but I'm apperantly still to green to get it, so I hope you can explain it to me in a more beginner-friendly way.
I want to use elixir to compile my scss from resources/assets/scss/styles.scss and then output the file to public/styles.css .
How do I set the custom path to my .scss file? Where is the file outputted, so I can .copy() it to public?
My styles.scss looks like this (yes, there are 2 assets folders in total. Laravels and my own):
/*! Testing Elixir */
//assets
#import 'assets/cssReset';
#import 'assets/variables';
#import 'assets/mixins';
//layouts
#import 'layouts/base';
#import 'layouts/dashboard';
#import 'layouts/logo';
#import 'layouts/forms';
#import 'layouts/siteNavigation';
#import 'layouts/lesson';
#import 'layouts/course';
#import 'layouts/courseList';
#import 'layouts/courseNavigation';
#import 'layouts/landingPage1';
#import 'layouts/landingPage2';
#import 'layouts/pagination';
#import 'layouts/footer';
//userMenu
#import 'layouts/menu';
It would be really helpfull if gulp gave some kind of feedback in the commandline when run.
My gulp.js
var elixir = require('laravel-elixir');
/*

|
*/
elixir(function(mix) {
mix.sass('app.scss');
});
Okay, so I finally figured where I went wrong.
I thought app in mix.sass('app.sass'); was a path variable, and . was the equivalent to / like with blade directory seperators, and then sass was the folder name. It turned out app.sass was a filename. Do'h...
When I renamed my path to: resources/assets/sass and then specified:
elixir(function(mix) {
mix.sass('styles.scss');
});
Gulp outputted the file here: public/css/styles.css
Hope this helps others that makes the same false assumptions like me.
Is there anyway to import a regular CSS file with Sass's #import command? While I'm not using all of the SCSS syntax from sass, I do still enjoy it's combining/compressing features, and would like to be able to use it without renaming all of my files to *.scss
After having the same issue, I got confused with all the answers here and the comments over the repository of sass in github.
I just want to point out that as December 2014, this issue has been resolved. It is now possible to import css files directly into your sass file. The following PR in github solves the issue.
The syntax is the same as now - #import "your/path/to/the/file", without an extension after the file name. This will import your file directly. If you append *.css at the end, it will translate into the css rule #import url(...).
In case you are using some of the "fancy" new module bundlers such as webpack, you will probably need to use use ~ in the beginning of the path. So, if you want to import the following path node_modules/bootstrap/src/core.scss you would write something like #import "~bootstrap/src/core".
NOTE:
It appears this isn't working for everybody. If your interpreter is based on libsass it should be working fine (checkout this). I've tested using #import on node-sass and it's working fine. Unfortunately this works and doesn't work on some ruby instances.
This was implemented and merged starting from version 3.2 (pull #754 merged on 2 Jan 2015 for libsass, issues originaly were defined here: sass#193 #556, libsass#318).
To cut the long story short, the syntax in next:
to import (include) the raw CSS-file the syntax is **without `.css`** extension at the end (results in actual read of partial `s[ac]ss|css` and include of it inline to SCSS/SASS):
#import "path/to/file";
to import the CSS-file in a traditional way syntax goes in traditional way, **with `.css` extension** at the end (results to `#import url("path/to/file.css");` in your compiled CSS):
#import "path/to/file.css";
And it is damn good: this syntax is elegant and laconic, plus backward compatible! It works excellently with libsass and node-sass.

To avoid further speculations in comments, writing this explicitly: Ruby based Sass still has this feature unimplemented after 7 years of discussions. By the time of writing this answer, it's promised that in 4.0 there will be a simple way to accomplish this, probably with the help of #use. It seems there will be an implementation very soon, the new "planned" "Proposal Accepted" tag was assigned for the issue #556 and the new #use feature.
UPD: on 26 October 2020 lib-sass was deprecated, therefore issue #556 was immediately closed.
__
answer might be updated, as soon as something changes.
Looks like this is unimplemented, as of the time of this writing:
https://github.com/sass/sass/issues/193
For libsass (C/C++ implementation), import works for *.css the same way as for *.scss files - just omit the extension:
#import "path/to/file";
This will import path/to/file.css.
See this answer for further details.
See this answer for Ruby implementation (sass gem)
You must prepend an underscore to the css file to be included, and switch its extension to scss (ex: _yourfile.scss). Then you just have to call it this way:
#import "yourfile";
And it will include the contents of the file, instead of using the CSS standard #import directive.
Good news everyone, Chris Eppstein created a compass plugin with inline css import functionality:
https://github.com/chriseppstein/sass-css-importer
Now, importing a CSS file is as easy as:
#import "CSS:library/some_css_file"
If you have a .css file which you don't wish to modify, neither change its extension to .scss (e.g. this file is from a forked project you don't maintain), you can always create a symlink and then import it into your .scss.
Creates a symlink:
ln -s path/to/css/file.css path/to/sass/files/_file.scss
Imports symlink file into a target .scss:
#import "path/to/sass/files/file";
Your target output .css file is going to hold contents from imported symlink .scss file, not a CSS import rule (mentioned by #yaz with highest comment votes). And you don't have duplicated files with different extensions, what means any update made inside initial .css file immediately gets imported into your target output.
Symbolic link (also symlink or soft link) is a special type of file
that contains a reference to another file in the form of an absolute
or relative path and that affects pathname resolution.
– http://en.wikipedia.org/wiki/Symbolic_link
You can use a third-party importer to customise #import semantics.
node-sass-import-once, which works with node-sass (for Node.js) can inline import CSS files.
Example of direct usage:
var sass = require('node-sass');,
importOnce = require('node-sass-import-once');
sass.render({
file: "input.scss",
importer: importOnce,
importOnce: {
css: true,
}
});
Example grunt-sass config:
var importOnce = require("node-sass-import-once");
grunt.loadNpmTasks("grunt-sass");
grunt.initConfig({
sass: {
options: {
sourceMap: true,
importer: importOnce
},
dev: {
files: {
"dist/style.css": "scss/**/*.scss"
}
}
});
Note that node-sass-import-once cannot currently import Sass partials without an explicit leading underscore. For example with the file partials/_partial.scss:
#import partials/_partial.scss succeeds
#import * partials/partial.scss fails
In general, be aware that a custom importer could change any import semantics. Read the docs before you start using it.
If I am correct css is compatible with scss so you can change the extension of a css to scss and it should continue to work. Once you change the extension you can import it and it will be included in the file.
If you don't do that sass will use the css #import which is something you don't want.
I figured out an elegant, Rails-like way to do it. First, rename your .scss file to .scss.erb, then use syntax like this (example for highlight_js-rails4 gem CSS asset):
#import "<%= asset_path("highlight_js/github") %>";
Why you can't host the file directly via SCSS:
Doing an #import in SCSS works fine for CSS files as long as you explicitly use the full path one way or another. In development mode, rails s serves assets without compiling them, so a path like this works...
#import "highlight_js/github.css";
...because the hosted path is literally /assets/highlight_js/github.css. If you right-click on the page and "view source", then click on the link for the stylesheet with the above #import, you'll see a line in there that looks like:
#import url(highlight_js/github.css);
The SCSS engine translates "highlight_js/github.css" to url(highlight_js/github.css). This will work swimmingly until you decide to try running it in production where assets are precompiled have a hash injected into the file name. The SCSS file will still resolve to a static /assets/highlight_js/github.css that was not precompiled and doesn't exist in production.
How this solution works:
Firstly, by moving the .scss file to .scss.erb, we have effectively turned the SCSS into a template for Rails. Now, whenever we use <%= ... %> template tags, the Rails template processor will replace these snippets with the output of the code (just like any other template).
Stating asset_path("highlight_js/github") in the .scss.erb file does two things:
Triggers the rake assets:precompile task to precompile the appropriate CSS file.
Generates a URL that appropriately reflects the asset regardless of the Rails environment.
This also means that the SCSS engine isn't even parsing the CSS file; it's just hosting a link to it! So there's no hokey monkey patches or gross workarounds. We're serving a CSS asset via SCSS as intended, and using a URL to said CSS asset as Rails intended. Sweet!
To import a regular CSS file into Sass:
Official Sass Documentation: Import CSS into Sass
Simple workaround:
All, or nearly all css file can be also interpreted as if it would be scss. It also enables to import them inside a block. Rename the css to scss, and import it so.
In my actual configuration I do the following:
First I copy the .css file into a temporary one, this time with .scss extension. Grunt example config:
copy: {
dev: {
files: [
{
src: "node_modules/some_module/some_precompiled.css",
dest: "target/resources/some_module_styles.scss"
}
]
}
}
Then you can import the .scss file from your parent scss (in my example, it is even imported into a block):
my-selector {
#import "target/resources/some_module_styles.scss";
...other rules...
}
Note: this could be dangerous, because it will effectively result that the css will be parsed multiple times. Check your original css for that it contains any scss-interpretable artifact (it is improbable, but if it happen, the result will be hard to debug and dangerous).
to Import css file in to scss simply use the this:
#import "src/your_file_path";
without using extension .css at the end
It is now possible using:
#import 'CSS:directory/filename.css';
I can confirm this works:
class CSSImporter < Sass::Importers::Filesystem
def extensions
super.merge('css' => :scss)
end
end
view_context = ActionView::Base.new
css = Sass::Engine.new(
template,
syntax: :scss,
cache: false,
load_paths: Rails.application.assets.paths,
read_cache: false,
filesystem_importer: CSSImporter # Relevant option,
sprockets: {
context: view_context,
environment: Rails.application.assets
}
).render
