import global scss variables with Vue CLI and Vuetify - vue.js

when importing a global scss file into my project via:
import into main.js, didn't let me use the variables i defined but classes and ids work.
import into App.vue, didn't load any styles at all. and i removed the scoped of course
import into vue.config.js as following
module.exports = {
transpileDependencies: [
'vuetify'
],
css: {
loaderOptions: {
sass: {
prependData: '#import "#/scss/_variables.scss";'
}
}
}
}
breaks my whole application and gives me tons of errors in cmd rel. to Vuetify.
can anybody tell me how i can import a global scss into a SPA made with latest Vue CLI and Vuetify?

You don't need to import the variables explicitly. According to the official documentation https://vuetifyjs.com/en/customization/sass-variables vue-cli-plugin-vuetify do this itself. To use global variables just follow these simple steps.
Add Vuetify using command vue add vuetify This will automatically add all the required dependency like vuetify-loader, vue-cli-plugin-vuetify, etc.
Make a variables.scss file in src/{scss, sass or styles} directory. As these are the default directories for global variables Example variable file.
Run the server, you are ready to go.

In general, this seems to work now:
// vue.config.js
module.exports = {
css: {
loaderOptions: {
sass: {
additionalData: '#import "~#/assets/scss/_variables.scss";'
}
}
}
}

Symfony: How to Import a Sass File into Every Vue Component

I am currently struggling with this. In my Symfony project I have a _variables.scss file, where I keep my global variables (e.g. colors).
This is included in my main scss file like this #import "variables"; - which works fine. Now I also use VueJs in my project and I would like to use my global variables inside Vue components. Now one way to achieve this is just importing the variables.scss itself:
//CustomButton.vue
<template>
...
</template>
<script>
export default {
name: "CustomButton"
}
</script>
<style lang="scss" scoped>
#import "../../scss/_variables.scss";
//able to use variables here
</style>
However with a growing project and different paths, this seems to be unnecessary work. What I'd like to achieve is to load the variables.scss into every Vue component automatically.
This is quite well explained here: [css-tricks.com - How to Import a Sass File into Every Vue Component in an App][1]
Sadly this does not work in my case (I think the vue.config.js is ignored completly) - the variables are still not usable inside the Vue component. I also tried to add the JavaScript into my main js file - where I load Vue - however this seems to break stuff (some module exception).
Is there any specific way to achieve this with symfony?
PS: I am using Symfony 5, Sass-Loader 9.0.1, Vue 2.6.12, Vue-Loader 15, Vue-Template-Compiler 2.6.12
[1]: https://css-tricks.com/how-to-import-a-sass-file-into-every-vue-component-in-an-app/
Solution 1:
//webpack.config.js
.enableSassLoader(options => {
options.additionalData = `
#import "./assets/scss/_variables.scss"; //path.resolve is not working in my case to import the absolute path
`
})
```
Webpack config:
module.exports = {
...
module: {
rules: [
{
test: /\.scss$/,
use: [
process.env.NODE_ENV !== 'production'
? 'vue-style-loader'
: MiniCssExtractPlugin.loader,
'css-loader',
{
loader: 'sass-loader',
options: {
data: `
#import "functions";
#import "variables";
#import "mixins";
`,
includePaths: [
path.resolve(__dirname, "../asset/scss/framework")
]
}
}
]
},
]
}
this config imports 3 files: "_functions.scss", "_variables.scss", "_mixins.scss" from folder"../asset/scss/framework" and no need to use #import "../../scss/_variables.scss"; every time in your vue components. Maybe, you will adapt this webpack config to your needs or will get some idea to resolve your issue.
This is what you need c:
Since you are using Encore, modify your webpack.config.js, add this code
var Encore = require('#symfony/webpack-encore');
Encore.configureLoaderRule('scss', (loaderRule) => {
loaderRule.oneOf.forEach((rule) => {
rule.use.push({
loader: 'sass-resources-loader',
options: {
resources: [
// Change this url to your _variables.scss path
path.resolve(__dirname, './assets/app/styles/_vars.scss'),
]
},
})
})
})
You also are going to have to install sass-resources-loader
npm install sass-resources-loader
Then compile your code again and your sass variables will be available everywhere
Solution to my question:
//webpack.config.js
.enableSassLoader(options => {
options.additionalData = `
#import "./assets/scss/_variables.scss"; //path.resolve is not working in my case to import the absolute path
`
})
this will import the file in every sass template + vue component

Overriding Vuetify variables

I'm using Vuetify in my project, and I want to use a variable file to override the styles generated by Vuetify.
I'm loading the components and their corresponding styles using the a-la-carte method, so I'm NOT importing the Vuetify SASS file using this:
#import '~vuetify/src/styles/styles.sass'
// Not using this method because I don't want to generate styles that are not being used by
// vuetify components I'm not using
Also, my project is using *.scss, not *.sass.
I'm also injecting a global SCSS file containing mixins and other variables in my vue.config.js:
css: {
sourceMap: productionSourceMap,
loaderOptions: {
scss: {
prependData: `#import '#/scss/_common.scss';`
}
}
},
I included a Vuetify variable, $border-radius-root, in that common.scss file, but it doesn't seem to have any effect.
Any idea how to do what I want without having to write entirely new CSS rules to override Vuetify's generated stylesheet? Basically I want to change the units that Vuetify uses using their own stylesheet generator.
Actually the solution is, and I'm dumb for not thinking of this before, to add another loader to vue.config.js:
css: {
sourceMap: productionSourceMap,
loaderOptions: {
scss: {
prependData: `#import '#/scss/_common.scss';`
},
sass: {
prependData: `#import '#/sass/_vuetify-variables.sass';`
}
}
},
Since vuetify is using sass as the css pre-processor, it needs sass-loader to handle the variable overrides and apply it to the framework.
If you are using Nuxt:
you can add customVariable path in your nuxt.config.js file, in vuetify object
Note you have to enable treeShake. This option is required for custom SASS variables to work
example:
vuetify: {
// usually file should be in assets folder
customVariables: ['~/path/to/variables.scss'],
treeShake: true,
}
If you are using Vue CLI:
Create a folder with name: sass, scss, or styles
Create new file inside this folder and name it: variables.scss or variables.sass
vuetify-loader will automatically bootstrap your variables into Vue CLI’s compilation process, overwriting the framework defaults.
From Vuetify docs:
If you have not installed Vuetify, check out the quick-start guide. Once installed, create a folder called sass, scss or styles in your src directory with a file named variables.scss or variables.sass. The vuetify-loader will automatically bootstrap your variables into Vue CLI's compilation process, overwriting the framework defaults.
So, the vuetify-loader automatically loads #/scss/variables.scss in a Vue CLI project, so you could set $border-radius-root in that file, and it will overrride the framework default.

Loading vuetify in a package that i use in a vuetify project

What is the correct way of loading vuetify into a package that i use in a vuetify project?
When serving projects it all seems to work fine but when i build the project i've got some issues with the css/sass
things i've tried:
With vuetify loader: the css is loaded twice so i can't overwrite sass variables
Without vuetify loader: the package doesn't have the vuetify css, so it looks horrible
Without vuetify loader with vuetify.min.css: the css is loaded twice so i can't overwrite sass variables, and the loaded css is all the css so it's huge
My package is called vuetify-resource, and this is the source code of the index.js (without the vuetify loader) At this point everything works on npm run serve But when i build the package doesn't have "access" to the vuetify css.
import Vue from 'vue';
import Vuetify from 'vuetify';
import VuetifyResourceComponent from './VuetifyResource.vue';
Vue.use(Vuetify);
const VuetifyResource = {
install(Vue, options) {
Vue.component('vuetify-resource', VuetifyResourceComponent);
},
};
export default VuetifyResource;
To solve my issue i had to do a couple of things.
Make peer dependencies of vuetify and vue
add vuetify to the webpack externals, so when someone uses the package, the package uses that projects vuetify
not longer import vue and vuetify in the index.js it's not needed, the project that uses the package imports that
import the specific components that you use in every .vue file
for example:
Vue.config.js
module.exports = {
configureWebpack: {
externals: {'vuetify/lib': 'vuetify/lib'},
},
};
index.js
import VuetifyResourceComponent from './VuetifyResource.vue';
const VuetifyResource = {
install(Vue, options) {
Vue.component('vuetify-resource', VuetifyResourceComponent);
},
};
export default VuetifyResource;
part of the component.vue
import { VDataTable } from 'vuetify/lib';
export default {
name: 'vuetify-resource',
components: {
VDataTable
},
Step 4 in Ricardo's answer is not needed if you use vuetify-loader, it will do the job for you.
And I would modify step 2 to also exclude Vuetify's styles/css from your bundle. If you don't exclude them you can run into styling issues when the Vuetify version differ between your library and your application.
Use a regular expression in vue.config.js like this: configureWebpack: { externals: /^vuetify\// }. That way, only your own styles are included in the library bundle.

How to import whole SCSS folder in Vue Nuxt project?

At my company we are not writing css in Vue files, we prefer to do it the old way with SCSS.
Problem is, we end up with a need of writing new import in styles.scss any time we create new component, and it really bugs me in bigger projects.
Not so long ago, when I have been developing in React, I imported module called node-sass-glob-importer in webpack.config file, tweaked a bit (you can check here) and it worked - I could have imported folder like this: #import "components/**";
In Nuxt, I only have nuxt.config.js file and I am lost a bit. I know how to extend some simple stuff there, but this seems to be more complicated.
Any help of importing node-sass-glob-importer or doing the same thing in some other way?
how about using https://github.com/nuxt-community/style-resources-module and than:
export default {
modules: ['#nuxtjs/style-resources'],
styleResources: {
scss: [
'./assets/yourFolder/*.scss'
]
}
}
You can use node-sass-glob-importer in Nuxt like this:
nuxt.config.js:
const globImporter = require('node-sass-glob-importer');
export default {
...
css: [
'~/assets/scss/global.scss'
],
...
build: {
extend(config, {loaders: {scss}}) {
const sassOptions = scss.sassOptions || {};
sassOptions.importer = globImporter();
scss.sassOptions = sassOptions;
}
}
}
global.scss:
#import "./assets/scss/base/*";
#import "./assets/scss/components/*";
styleResources is used for things like variables, mixins and functions that you want to use anywhere in your SCSS without having to import the files.

Dedupe CSS in Vue.js development mode

I am working on a Vue.js project that heavily uses single file components. These components have scss styles associated with them.
In production mode the duplicate css that occurs from importing the same component multiple times is filtered out. But in development mode the same scss is imported multiple times.
This leads to slow downs with the chrome debugger when inspecting and modifying the css.
Does anone know a way to dedupe the css/scss attatched to single file components in developlment mode?
Here is my current vue config:
module.exports = {
lintOnSave: false,
configureWebpack: {
resolve: {
alias: require("./aliases.config").webpack
},
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
_: "lodash"
}),
new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/)
]
}
Here's how we ended up solving it.
Import only pure SCSS in components (ie. mixins, variables, functions). If a file with CSS is imported in each component the sass loader will NOT dedupe the CSS in development mode.
In your vue config add the following to include you scss variables in every single file component:
module.exports = {
...
css: {
loaderOptions: {
sass: {
data: `
#import "#src/_variables.scss";
`
}
}
},
...
}
Import your global scss in your app entry (main.js or equivalent)
import "bootstrap";
import "#src/global.scss";
In your global.scss file you can import your variables file so that it can also access your scss variables.
