Vue app custom scss file - change font across entire app?

I'm trying to change the app across the entire vue app, I have a custom scss file that is imported into main.ts in the app. So far I have this but don't think its working any suggestions?
$theme-colors: (
"primary": #5e72e4,
);
$vue-slider-mark-label: (
"font-size": 18px,
);
#import url('https://fonts.googleapis.com/css?family=Montserrat&display=swap');
$body-font-family: 'Montserrat';
$font-size-root: 14px !default;
v-app {
font-family: $body-font-family !important;
}
#import "node_modules/bootstrap/scss/bootstrap";
#import "node_modules/bootstrap-vue/src/index.scss";

What you trying to do can be achieved by importing your google font inside of your <style> tag, in best case, in App.vue, your main component.
#import url('https://fonts.googleapis.com/css?family=Montserrat&display=swap');
Then you can use it like this. Please not to not scope this attributes:
html, body {
font-family: 'Montserrat', sans-serif;
}
#app {
font-family: 'Montserrat', sans-serif;
}

How to toggle base css with darkmode css conditionally and using variables in vuejs?

I have created a _darkmode.scss file to apply dark mode globally on my laravel+vuejs application.
I do not know how to replace/toggle it with base css i.e app.css which is generated using webpack mix function.
I have a toggle switch in nav bar, on #change event this file (_darkmode.scss) should be included / excluded.
mix
.js("resources/assets/js/app.js", `${publicPath}/js`)
.sass("resources/assets/sass/app.scss", `${publicPath}/css`)
.extract(toExtract)
.setPublicPath(publicPath)
.setResourceRoot("../")
.browserSync({
proxy: "http://localhost:8000",
port: 8080,
files: [`${publicPath}/*`]
});
if (mix.inProduction()) {
mix.version();
}
This is my app.scss file where I import other styles
#import "variables";
// Bootstrap
#import "~bootstrap/scss/bootstrap";
#import "~font-awesome/scss/font-awesome";
#import url("https://fonts.googleapis.com/css?family=Poppins:200,200i,300,300i,400,400i,500,500i,600,600i,700,700i,800,800i,900,900i");

How do I import files into a scoped style tag without it bleeding out?

I'm importing a css file in a style tag using a .vue file. The scoped css file is affecting all the css on my page and I only want it to affect my current component.
<template>
<div>
<router-view></router-view>
</div>
</template>
<style type="text/css" scoped>
#import '~bootstrap/dist/css/bootstrap.css';
</style>
How do I import a css file that is scoped to my current component?

Can you use sass?
First you'd have to install sass-loader:
npm install sass-loader node-sass --save-dev
Then you can use it like this:
<template>
<div class="container">
<router-view></router-view>
</div>
</template>
<style lang="scss" scoped>
.container {
#import '~bootstrap/dist/css/bootstrap.css';
}
</style>

What is best way for including bootstrap.css to nuxt project?

This is a part of my nuxt.config.js file:
head: {
link: [
{ rel: 'icon', type: 'image/x-icon', href: '/favicon.ico' },
// load bootsttrap.css from CDN
//{ type: 'text/css', rel: 'stylesheet', href: '//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css' },
]
},
css: [
// this line include bootstrap.css in each html file on generate
'bootstrap/dist/css/bootstrap.css',
'assets/main.css'
],
In this case bootstrap.css included in each html file on nuxt generate.
For resolve it I comment line 'bootstrap/dist/css/bootstrap.css' in css section and uncomment rel stylesheet line in link section.
After this bootstrap.css file loaded from CDN and not included in html files. So, I think it not is very well idea.
How copy bootstrap.css from 'node_modules/bootstrap/dist/...' to '~/assets' on build, and after this, load it from here?

Steps to include bootstrap.css into a nuxt project:
1 .Install bootstrap-vue
npm i bootstrap-vue
2.Create the file plugins/bootstrap-vue.js and in it type:
/* eslint-disable import/first */
import Vue from 'vue'
import BootstrapVue from 'bootstrap-vue'
Vue.use(BootstrapVue)
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'
3.Add created plugin to nuxt.config.js:
plugins: [
'#/plugins/bootstrap-vue',
],
After these steps it should work and you can use bootstrap.

This is the simplest way I have found to include the regular Bootstrap version (not Bootstrap-Vue) in your Nuxt.js project. First, install Bootstrap from your Nuxt.js project directory (I'm using version 5.0.0-beta2):
npm install bootstrap
Then, in nuxt.config.js file, include Bootstrap's CSS and Javascript like this:
css: [
"~/node_modules/bootstrap/dist/css/bootstrap.min.css"
],
plugins: [
{ src: "~/node_modules/bootstrap/dist/js/bootstrap.bundle.min.js", mode: "client" }
],
Note the mode: "client" flag which indicates that the Javascript should only be run on the client. This prevents a ReferenceError: document is not defined error that happens because Bootstrap is not compatible with server side rendering.

For me the best way if you are using scss
As for me i create a sass directory inside assets directory in nuxt.
Then i add app.scss file inside sass directory i just created.
Then inside app.scss i import the following:
#import "bootstrap-variable-override";
#import "~bootstrap/scss/bootstrap.scss";
Then i do yarn add node-sass sass-loader --save
After that in nuxt.config.js i modify css array to include my app.scss
css: [
'#/assets/sass/app.scss'
],
This will compile whatever scss i will write and import in app.scss and provide as a compiled css.
But if you are bootstrap-vue then all you need to do is add this as modules:
modules: ['bootstrap-vue/nuxt']

Way to add Bootstrap 5 with nuxt.js:
If you don't want to do it manually by reading the following answer, you can simply clone my bootstrap 5 with nuxt boilerplate repository, click here.
Installation
npm install bootstrap#next
Note: The command will change, currently bootstrap 5 is in the beta version.
After installing the bootstrap, you will know that you need to install some loaders to compile Bootstrap.
npm install --save-dev sass sass-loader fibers postcss postcss-loader autoprefixer
Note: Installation of fibers is not mentioned in bootstrap documentation but synchronous compilation with sass (2x speed increase) is enabled automatically when fibers is installed.
Adding the CSS Part of Bootstrap and the Customized Bootstrap
At first, create a folder in your nuxt project’s assests folder and also create a scss file inside the created folder. Suppose, the folder’s name is bootstrap and the file name is ‘mystyle.scss’. Now, on this mystyle.scss file, you can override any built-in custom Bootstrap variables.
But you need to import bootstrap styles in this mystyle.scss too.After that, you need the following line to import bootstrap styles
#import "~bootstrap/scss/bootstrap";
Note: Make sure that you import this in the last line of your .scss file.
After importing the bootstrap style, you need to edit the nuxt.config.js
export default {
css: [ { src: '~/assets/bootstrap/mystyle.scss', lang: 'sass'}
],
}
This will not only compile the overridden bootstrap styles but also add the bootstrap style in the whole nuxt project.
Adding the Javascript Part of Bootstrap
First, download bootstrap. You will get a css and a js folder on that downloaded folder. There are many files under those two folders.
We just need one file from js folder. The name of that file is bootstrap.bundle.min.js. Copy that 'bootstrap.bundle.min.js' file and paste that file on your nuxt project's static folder. Then you need to edit your nuxt.config.js to use it.
export default {
script: [
{
src: '/bootstrap.bundle.min.js',
}
]
}
That's it, enjoy!
You can read about it in detail in my medium article, click here.

If you are looking to centralize your CSS imports (specifically bootstrap from node_modules, in your case) into a single file for Nuxt generating, you could include an at-rule import to your 'assets/main.css' (recommend to update it to '~/assets/main.css') specified in your config.
#import '../node_modules/bootstrap/dist/css/bootstrap.css'
Just a reminder: when you simply run Nuxt in dev mode, the CSS will be injected via JS. When generated, however, Nuxt will create a single, hashed, CSS file as part of the document root directory.

In my case, I put bootstrap.css file in "static" folder, and then register it to the nuxt.config.js as bellow
head: {
title: "Nuxt",
meta: [
{ charset: "utf-8" },
{ name: "viewport", content: "width=device-width, initial-scale=1" },
{
hid: "description",
name: "description",
content: "Nuxt"
}
],
link: [
{ rel: "icon", type: "image/x-icon", href: "/favicon.ico" },
{ rel: "stylesheet", href: "/css/bootstrap.css" } //Register your static asset
]
},

Here is my setup, and this is for those who like to customize bootstrap default style:
In my assets/styles/_bootstrap.scss I have imported required style:
#import "~bootstrap/scss/functions";
#import "~bootstrap/scss/variables";
#import "~bootstrap/scss/mixins";
//#import "~bootstrap/scss/root";
#import "~bootstrap/scss/reboot";
#import "~bootstrap/scss/type";
//#import "~bootstrap/scss/images";
//#import "~bootstrap/scss/code";
#import "~bootstrap/scss/grid";
//#import "~bootstrap/scss/tables";
#import "~bootstrap/scss/forms";
#import "~bootstrap/scss/buttons";
#import "~bootstrap/scss/transitions";
//#import "~bootstrap/scss/dropdown";
//#import "~bootstrap/scss/button-group";
//#import "~bootstrap/scss/input-group";
//#import "~bootstrap/scss/custom-forms";
//#import "~bootstrap/scss/nav";
//#import "~bootstrap/scss/navbar";
//#import "~bootstrap/scss/card";
//#import "~bootstrap/scss/breadcrumb";
//#import "~bootstrap/scss/pagination";
//#import "~bootstrap/scss/badge";
//#import "~bootstrap/scss/jumbotron";
//#import "~bootstrap/scss/alert";
//#import "~bootstrap/scss/progress";
//#import "~bootstrap/scss/media";
//#import "~bootstrap/scss/list-group";
#import "~bootstrap/scss/close";
#import "~bootstrap/scss/modal";
//#import "~bootstrap/scss/tooltip";
//#import "~bootstrap/scss/popover";
#import "~bootstrap/scss/carousel";
#import "~bootstrap/scss/utilities";
//#import "~bootstrap/scss/print";
Just in case you like to change the default style of bootstrap then I created assets/styles/_bootstrap-variables.scss:
There are lots of variable that you can find in node-modules/bootstrap/scss/variables.scss, I am just changing a few.
#import url('https://fonts.googleapis.com/css?family=Cabin:400,500,700');
$font-family-cabin: 'Cabin', sans-serif;
$font-family-base: $font-family-cabin;
$primary: #b62f20;
$secondary: #e8e8e9;
$success: #87b4a6;
$info: #f0f6fc;
//$warning: #faeecf;
//$danger: $red !default;
//$light: $gray-100 !default;
//$dark: $gray-800 !default;
And import all my other styles and plugins in one file assets/styles/main.scss:
#import "bootstrap-variables"; // this should alway be on top
#import "bootstrap";
#import "my-other-style";
And finally, import the stylesheet in layouts/default.vue
<template lang="pug">
div
nuxt
</template>
<style lang="scss">
#import '../assets/styles/main';
</style>

In my case, I add it from CDN as an object entry to link array (in nuxt.config.js)
link: [
{rel: 'stylesheet', type: 'text/css', href: 'https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css'}
]

You install bootstrap-vue :
yarn add bootstrap-vue
Then in the nuxt.config.js file you add a module, and a separate config for importing the icons :
modules: ['bootstrap-vue/nuxt'],
bootstrapVue: {
icons: true // Install the IconsPlugin (in addition to BootStrapVue plugin
}
And thats it.
For more configuration read the documentation here : https://bootstrap-vue.org/docs
(Read until the middle where it handles nuxt)

I used for Bootstrap v5
nuxt.config.js
css: [
'~/assets/scss/main.scss',
],
styleResources: {
scss: [
'~/node_modules/bootstrap/scss/_functions.scss',
'~/node_modules/bootstrap/scss/_variables.scss',
'~/node_modules/bootstrap/scss/_mixins.scss',

'~/node_modules/bootstrap/scss/_grid.scss'
]
},
modules: [
'#nuxtjs/style-resources',
],
#nuxtjs/style-resources to have mixins, variables, grid available inside components:

.header {
#include make-container();
