How to import css with webpack? - css

Question

TWO PART QUESTION
My steps:
Created empty folder
opend cmd
navigate to folder and run npm init -f
run vue init webpack
run npm install
npm i bootstrap-vue
npm run dev
my main.js:
import Vue from 'vue'
import App from './App'
import router from './router'
import BootstrapVue from 'bootstrap-vue'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'
Vue.use(BootstrapVue);
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
render: h => h(App)
})
webpack.base.conf.js:
var path = require('path')
var utils = require('./utils')
var config = require('../config')
var vueLoaderConfig = require('./vue-loader.conf')
function resolve(dir) {
return path.join(__dirname, '..', dir)
}
module.exports = {
entry: {
app: './src/main.js'
},
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production' ?
config.build.assetsPublicPath : config.dev.assetsPublicPath
},
resolve: {
extensions: ['.js', '.vue', '.json'],
alias: {
'#': resolve('src'),
}
},
module: {
rules: [{
test: /\.vue$/,
loader: 'vue-loader',
options: vueLoaderConfig
},
{
test: /\.js$/,
loader: 'babel-loader',
include: [resolve('src'), resolve('test')]
},
{
test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('img/[name].[hash:7].[ext]')
}
},
{
test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('media/[name].[hash:7].[ext]')
}
},
{
test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
}
},
{ //this rule will only be used for any vendors
test: /\.css$/,
loaders: ['style-loader', 'css-loader'],
include: [/node_modules/]
},
{
test: /\.css$/,
loaders: ['to-string-loader', 'css-loader'],
exclude: [/node_modules/] //add this line so we ignore css coming from node_modules
},
{
test: /\.css$/,
use: [
'style-loader',
'css-loader'
]
}
]
}
}
when I run this I get:
Module build failed: Unknown word (5:1)
Part 2:
After some time found a solution to the above problem by installing a loader package and changin my main.js to this:
import Vue from 'vue'
import App from './App'
import router from './router'
import '!style-loader!css-loader!bootstrap/dist/css/bootstrap.css';
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
render: h => h(App)
})
this solved my first problem BUT:
If i try to add a local css file like so:
import Vue from 'vue'
import App from './App'
import router from './router'
import '!style-loader!css-loader!bootstrap/dist/css/bootstrap.css';
import './content/bootstrapGrid.css'
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
render: h => h(App)
})
I again get the same error:
Module build failed: Unknown word (5:1)
I am new to webpack, vue and the entire SPA.
Been at this for a while now and im stuck, anyone that can see what I am missing?

Answer 1

!css-loader
This is the plain css loader. It will return the css code interpreting the resources inside, but it will not add it to the page.
With this loader #import and url(...) are interpreted like require() and will be resolved.
!style-loader
This loader adds CSS to the DOM by injecting a or tag.
To inject a you need to get the content of the css file, and then inject that.
require("style!raw!./file.css");
// => add rules in file.css to document
But it’s recommended to combine it with the css-loader, as it will interpret all the resources in your css file, instead of just having the raw css. (Check)
require("style!css!./file.css");
// => add rules in file.css to document
If you want to add a to your css file, you need to first have the url to that file, for that you can use the file-loader.
require("style/url!file!./file.css");
// => add a <link rel="stylesheet"> to file.css to document
Hope this helps!
