Not able to import css files in react - css

Question

In App.js I wanted to import App.css file or any css file. import './App.css' is not working here and giving error " ERROR in ./src/shared/App.css 1:0
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders "
Directory Structure -
1. public
- bundle.js
2. src
- browser (folder) > index.js
- server (folder) > index.js
- server (folder) > App.js , App.css
This is my webpack.config.js file -
var path = require('path')
var webpack = require('webpack')
var nodeExternals = require('webpack-node-externals')
var combineLoaders = require('webpack-combine-loaders');
var browserConfig = {
entry: './src/browser/index.js',
output: {
path: path.resolve(__dirname, 'public'),
filename: 'bundle.js',
publicPath: '/'
},
module: {
rules: [
{ test: /\.(js)$/, exclude: /node_modules/, use: ['babel-loader']},
{
test: /\.css$/,
exclude: /node_modules/,
loader: combineLoaders([
{
loader: 'style-loader'
}, {
loader: 'css-loader',
query: {
modules: true,
localIdentName: '[name]__[local]___[hash:base64:5]'
}
},
])
}
]
},
resolve: {
extensions: ['*', '.js', '.jsx', '.css']
},
mode: 'production',
plugins: [
new webpack.DefinePlugin({
__isBrowser__: "true"
})
]
}
var serverConfig = {
entry: './src/server/index.js',
target: 'node',
externals: [nodeExternals()],
output: {
path: __dirname,
filename: 'server.js',
publicPath: '/'
},
mode: 'production',
module: {
rules: [
{ test: /\.(js)$/, exclude: /node_modules/, use: ['babel-loader']},
{
test: /\.css$/,
exclude: /node_modules/,
loader: combineLoaders([
{
loader: 'style-loader'
}, {
loader: 'css-loader',
query: {
modules: true,
localIdentName: '[name]__[local]___[hash:base64:5]'
}
}
])
}
]
},
resolve: {
extensions: ['*', '.js', '.jsx', '.css']
},
plugins: [
new webpack.DefinePlugin({
__isBrowser__: "false"
})
]
}
module.exports = [browserConfig, serverConfig]

To load CSS files in your ReactJS project, install the css-loader for ReactJS...
npm install --save-dev style-loader css-loader
Also, make sure to modify your webpack.config.js file, located in my project at: ./node_modules/webpack-dev-server/client/webpack.config.js. You'll need to add loaders, which will look something like...
module.exports = {
module: {
loaders: [
{ test: /\.js$/, exclude: /node_modules/, loaders: 'babel', query: { presets: ['react', 'es2015', 'stage-1'] } },
{ test: /\.css$/, loader: "style-loader!css-loader" }
]
},
...
}
Finally, make sure you have a resolution rule for CSS in webpack.config.js...
resolve: {
extensions: ['', '.js', '.css',...]
}
