React not importing global css; local comp ok - css

React is not loading any global css. All local components are able to get its local styled-components. However, the global css is unable to generated to all components.
I've tried different import paths and tried on different file, also require(path). Not getting anything.
src
--modules
----component1
----component2
----asset
---------global.css
--index.js
global.css
.test-class{
font-size: 100px;
color:red;
}
at index.js
import './modules/assets/global.css'
render() {
return (<div className="test-class">Hello World</div>)}
HOWEVER if i use styledcomponents, it works.
Here's my webpack
module.exports = {
entry: ['babel-polyfill', './src/vendor.js', './src/index.js'],
plugins: [
new HTMLWebpackPlugin({
template: 'src/index.html'
}),
new MiniCssExtractPlugin({
filename: isDev ? '[name].css' : '[name].[hash].css',
chunkFilename: isDev ? '[id].css' : '[id].[hash].css'
})
],
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: ['babel-loader', 'eslint-loader']
},
{
test: /\.ts[x]?$/,
exclude: /node_modules/,
use: ['babel-loader', 'awesome-typescript-loader']
},
{
test: /\.s?[ac]ss$/,
use: [
'style-loader', // : MiniCssExtractPlugin.loader,
{
loader: 'css-loader',
options: {
importLoaders: 1,
modules: false
}
},
{
loader: 'postcss-loader',
options: {
path: '/postcss.config.js',
sourceMap: true
}
}
]
}
]
},
}

You are trying to get the classes from global.css but you are importing app.css in your index.js file. Import the correct file and you are set.
You are importing it correctly:
import './modules/assets/global.css';
Webpack looks good as well, but if you want to be sure just create a rule only for css since you don't seem to be using any scss or similar:
{test: /\.css$/, loader: 'style-loader'},
{
test: /\.css$/,
loader: 'css-loader',
options: {
importLoaders: 1,
modules: false
}
},

How can I load CSS styles using Webpack in React app?

I am having an issue with my React app. I have added Webpack and it is compiling successfully but, at the moment of serving the content, the app shows no styles at all.
This is what I have so far in my webpack.config.js file:
const path = require('path');
const BUILD_DIR = path.resolve(__dirname + '/public/build');
const APP_DIR = path.resolve(__dirname + '/src');
// This is the main configuration object.
// Here, you write different options and tell Webpack what to do
module.exports = {
experiments: {
asyncWebAssembly: true,
topLevelAwait: true,
layers: true // optional, with some bundlers/frameworks it doesn't work without
},
resolve: {
extensions: ['', '.js', '.jsx', '.css']
},
// Path to your entry point. From this file Webpack will begin its work
entry: [APP_DIR + '/index.js', APP_DIR + '/index.css', APP_DIR + '/App.css'],
// Path and filename of your result bundle.
// Webpack will bundle all JavaScript into this file
output: {
path: BUILD_DIR,
filename: 'bundle.js'
},
// Default mode for Webpack is production.
// Depending on mode Webpack will apply different things
// on the final bundle. For now, we don't need production's JavaScript
// minifying and other things, so let's set mode to development
mode: 'development',
module: {
rules: [
{
test: /\.js$/,
exclude: /(node_modules)/,
use: {
loader: 'babel-loader',
options: {
presets: ['#babel/preset-env']
}
}
},
{
test: /\.css$/,
use: [
{ loader: 'style-loader' },
{
loader: 'css-loader',
options: {
modules: true,
},
},
{ loader: 'sass-loader' },
{ loader: 'postcss-loader' }
],
},
]
}
};
Is there anything I am missing to get my css to work? I only have two files, located at /src: App.css and index.css. None of them seem to be loaded and I have no errors in the console.
rules: [
{
test: /\.js|jsx$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.(sass|scss|less|css)$/,
use: [
'style-loader',
'css-loader',
'sass-loader'
]
},
{
test: /\.(png|jpe?g|svg|gif)$/,
loader: 'file-loader'
},
{
test: /\.(woff|woff2|eot|ttf|otf)$/,
use: [
'file-loader',
]
},
{
test: /\.css$/,
use: [
{
loader: 'url-loader',
options: {
limit: false
}
}
]
}

Css of node-modules

I am using css modules in my react application. After setting modules:true inwebpack.config.js, I am able to get css from files which I created in my src folder. I am importing some components from node-modules. But the css of components present in node-modules is not getting applied.
I also tried importing css of node-modules using import 'path'; but it didnt work.
If I set modules:false, css of node-modules is getting applied and css of files in src folder is not getting applied.
webpack.config.js
module.exports = {
module: {
rules: [
{
test: /\.css$/,
use: [
{
loader: "style-loader"
},
{
loader: "css-loader",
options: {
modules: true,
},
}
],
},
],
},
};
This might be due to the node module you are using may not be following module syntax. I mean they might be setting classes directly with a string instead of using like style.someClassName. So, you need 2 entries in your rules 1 for your stuff and 1 for node modules.
for ex:
module.exports = {
module: {
rules: [{
test: /\.css$/,
exclude: /node_modules/,
use: [{
loader: "style-loader"
},
{
loader: "css-loader",
options: {
modules: true,
},
}
],
}, {
test: /\.css$/,
include: /node_modules/,
use: [{
loader: "style-loader"
},
{
loader: "css-loader",
options: {
modules: false,
},
}
],
}],
},
};

React-filepond external CSS is not being applied. I suspect it's a webpack issue

This is beating my head in. I'm using react-filepond module in my react app, but the external CSS is not being applied. The module works but has no style. I suspect it's a loader issue in webpack but I'm still learning webpack and probably missed something. Thanks!
Here are the imports as per react-filepond:
import { FilePond } from 'react-filepond';
import 'filepond/dist/filepond.css'; // located in node_modules
Here's my webpack.config.js.
I'm using webpack 3.12.0
const path = require('path');
const autoprefixer = require('autoprefixer');
const htmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
devtool: 'cheap-module-eval-source-map',
entry: './src/index.js',
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'bundle.js',
chunkFilename: '[id].js',
publicPath: '/'
},
resolve: {
extensions: ['.js', 'jsx', '.css']
},
module: {
rules: [
{
test: /\.js$/,
loader: 'babel-loader',
options: {
presets: ['react']
},
exclude: /node_modules/
},
{
test: /\.css$/,
use: [
{ loader: 'style-loader' },
{
loader: 'css-loader',
options: {
importLoaders: 1,
modules: true,
localIdentName: '[name]__[local]__[hash:base64:5]'
}
},
{
loader: 'postcss-loader',
options: {
ident: 'postcss',
plugins: () => [
autoprefixer({
browsers: [
"> 1%",
"last 2 versions"
]
})
]
}
}
]
},
{
test: /\.(png|jpe?g|gif)$/,
loader: 'url-loader?limit=8000&name=images/[name].[ext]'
}
]
},
devServer: {
historyApiFallback: true
},
plugins: [
new htmlWebpackPlugin({
template: __dirname + '/src/index.html',
inject: 'body',
filename: 'index.html'
})
]
};
I found the solution for others wondering about this.
Issue: I am using CSS modules in react (note the line modules:true in the configuration of my css-loader in my webpack-config.js
The external react module I was trying to use does NOT use CSS modules.
Solution:
create a second rule for external CSS. Thus I have one for my CSS (as in the source above) and then I added this rule:
{
/* External CSS from node_modules */
test: /\.css$/,
include: /node_modules/,
loader: [
require.resolve('style-loader'),
{
loader: require.resolve('css-loader'),
options: {
importLoaders: 1,
minimize: true,
},
}
]
},
Most importantly, I did NOT turn on CSS Modules
And then, in my other CSS rule, I added:
exclude: /node_modules/,

Webpack: extract css to its own bundle

I'm using webpack on a project. I use style-loader so I can import "my.css".
The css gets bundled with the javascript and will be rendered in a <style> tag when component mount, ok.
However, I would like to keep that import syntax and make webpack build a css bundle for every entry point.
So webpack output should be [name].bundle.js AND [name].bundle.css.
Is this something I can achieve ?
var config = {
entry: {
'admin': APP_DIR + '/admin.entry.jsx',
'public': APP_DIR + '/public.entry.jsx'
},
output: {
path: BUILD_DIR,
filename: '[name].bundle.js'
},
resolve: {
extensions: ['.js', '.jsx', '.json']
},
plugins: [],
devtool: 'cheap-source-map',
module: {
loaders: [{
test: /(\/index)?\.jsx?/,
include: APP_DIR,
loader: 'babel-loader'
},
{
test: /\.scss$/,
loaders: [
'style-loader',
'css-loader',
'sass-loader',
{
loader: 'sass-resources-loader',
options: {
resources: ['./src/styles/constants.scss']
},
}
]
}
],
}
};
along with this babel.rc:
{
"presets" : ["es2015", "react"],
"plugins": ["transform-decorators-legacy", "babel-plugin-root-import"]
}
Yes, you need to use extract-text-webpack-plugin. You might want to do it only on your production config. Config looks like this:
const ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
module: {
rules: [
{
test: /\.scss$/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
//resolve-url-loader may be chained before sass-loader if necessary
use: ['css-loader', 'sass-loader']
})
}
]
},
plugins: [
new ExtractTextPlugin('style.css')
//if you want to pass in options, you can do so:
//new ExtractTextPlugin({
// filename: 'style.css'
//})
]
}

How can I compile and load the pure CSS in ReactJS with webpack?

I am using a simple CSS based template for a ReactJS application with webpack module and not able to connect the CSS after compilation.
My webpack configuration looks like this...
var rucksack = require('rucksack-css')
var webpack = require('webpack')
var path = require('path')
module.exports = {
context: path.join(__dirname, './src'),
entry: {
css : './public/assets/css/main.css',
jsx: './index.js',
html: './public/index.html',
vendor: [
'react',
'react-dom',
'react-redux',
'react-router',
'react-router-redux',
'redux'
]
},
output: {
path: path.join(__dirname, './static'),
filename: 'bundle.js',
},
module: {
loaders: [
{
test: /\.html$/,
loader: 'file?name=[name].[ext]'
},
{
test: /\.css$/,
include: /src/,
loaders: [
'style-loader',
'css-loader?modules&sourceMap&importLoaders=1&localIdentName=[local]___[hash:base64:5]',
'postcss-loader'
]
},
{
test: /\.css$/,
exclude: /src/,
loader: 'style!css'
},
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
loaders: [
'react-hot',
'babel-loader'
]
},
],
},
resolve: {
extensions: ['', '.js', '.jsx']
},
postcss: [
rucksack({
autoprefixer: true
})
],
plugins: [
new webpack.optimize.CommonsChunkPlugin('vendor', 'vendor.bundle.js'),
new webpack.DefinePlugin({
'process.env': { NODE_ENV: JSON.stringify(process.env.NODE_ENV || 'development') }
})
],
devServer: {
contentBase: './src',
hot: true
}
}
and relative path for my css file is 'src/public/assets/css/main.css'.
Is there any way to use pure traditional CSS without changing it to the react based CSS-in-JS ?
I keep the CSS as a seprate thing, i use gulp or grunt to make things easyer then include the files as your base html
You could use the extract-text-webpack-plugin to pull your css out of your JS files. I believe the general best practice is to use the 'CSS-in-JS' (as you mentioned it) while working in development to benefit from hot-reloading. And then using the plugin above to build for production.
Also, it seems as though your config file has some redundancy.
{
test: /\.css$/,
include: /src/,
loaders: [
'style-loader',
'css-loader?modules&sourceMap&importLoaders=1&localIdentName=[local]___[hash:base64:5]',
'postcss-loader'
]
},
{
test: /\.css$/, // <--- this test seems redunant. Perhaps remove it.
exclude: /src/,
loader: 'style!css'
},
