I install sass-loader, css-loader and style-loader. Here's my webpack config:
var HTMLWebpackPlugin = require('html-webpack-plugin');
var HTMLWebpackPluginConfig = new HTMLWebpackPlugin({
template: __dirname + '/app/index.html',
filename: 'index.html',
inject: 'body'
});
module.exports = {
entry: __dirname + '/app/index.js',
module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.scss$/,
loaders: ['style-loader', 'css-loader']
}
]
},
output: {
filename: 'index.js',
path: __dirname + '/build'
},
plugins : [HTMLWebpackPluginConfig]
};
I have 2 scss file within the same folder: main.scss and variable.scss. I want yo import variable .scss into main.scss but failed with the error message:"Module not found: Error: Can't resolve 'variables' ". Here is my main.scss:
#import "variables";
body {
color: black;
}
You probably need to install and also add the config for the sass-loader, which also requires node-sass as a dependency: https://github.com/webpack-contrib/sass-loader

I am using webpack 4.7.0 with webpack-cli installed. This is for a react-js app. Here is my webpack.config.js:
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const HtmlWebpackPluginConfig = new HtmlWebpackPlugin({
template: './client/index.html',
filename: 'index.html',
'inject': 'body'
});
module.exports = {
entry: './client/index.js',
output: {
path: path.resolve('dist'),
filename: 'bundle.js'
},
module: {
rules: [
{
test: /\.css$/,
use: [
{ loader: "style-loader" },
{ loader: "css-loader" }
]
},
{
test: /\.js$/,
exclude: /node_modules/,
use: "babel-loader"
}
]
}
plugins: [HtmlWebpackPluginConfig]
}
Now when I run the command node_modules.bin\webpack --config webpack.config.js, I get the following error message:
plugins: [HtmlWebpackPluginConfig]
^^^^^^^
SyntaxError: Unexpected identifier
And I am not able to build my application. Here is my npm -v & node -v: 5.7.1
v9.4.0. How do I solve this issue?
I was trying to get react-toolbox to run.
Got the error 'Cannot find module precss' but this is the same code I picked up from the site. Am I missing out on something?
postcss.config.js
module.exports = {
plugins: [
require('precss'),
require('autoprefixer')
]
}
webpack.config.js
var HTMLWebpackPlugin = require('html-webpack-plugin');
var HTMLWebpackPluginConfig = new HTMLWebpackPlugin({
template: __dirname + '/app/index.html',
filename: 'index.html',
inject: 'body'
});
module.exports = {
entry: __dirname + '/app/index.js',
module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel-loader'
},
{
test: /\.css$/,
loaders: [
'style-loader',
'css-loader?importLoaders=1',
'postcss-loader'
]
}
]
},
output: {
filename: 'transformed.js',
path: __dirname+'/build'
},
plugins: [HTMLWebpackPluginConfig]
};
Any thoughts?
What does your package.json look like? Have you added precss as a dependency to your project? You always have to make sure that everything you import/use actually exists in the project.
You can check this by opening your package.json file and checking if it's in the list of dependencies. If it isn't try running:
npm install --save precss
This will install it in your project and you should be able to run the command again.
I have implemented webpack config like
/* eslint-disable no-var */
var path = require('path');
var webpack = require('webpack');
module.exports = {
entry: [
'webpack-hot-middleware/client',
'./src/main'
],
devtool: 'eval-source-map',
output: {
path: __dirname,
filename: 'bundle.js',
publicPath: '/static/'
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin()
],
module: {
loaders: [{
test: /\.js$/,
loaders: ['babel'],
include: path.join(__dirname, 'src')
},
{
test: /\.css$/, // Only .css files
loader: 'style!css' // Run both loaders
}
]
}
};
and I have installed the css-loader style-loader for loding the css on my page and I am using the bootstrap.min.css as below
require('../../node_modules/bootstrap/dist/css/bootstrap.min.css');
it's throw error like
Bootstrap is using the Glyphicons font. You also need to have a loader for the font:
{
test: /\.woff$/,
loader: 'url?limit=100000'
}
Source: christianalfoni.github.io/react-webpack-cookbook/Inlining-fonts
Or:
{
test: /\.(ttf|eot|svg|woff(2)?)(\?[a-z0-9]+)?$/,
loader: 'file-loader'
}

I'm trying to setup a React project with react-css-modules, webpack and Hot Module Replacement. Everything is working like a charm but I can't get the CSS sourcemaps to work.
I followed this guide to make HMR work. It involves a BrowserSync setup to update the css file after Webpack writes it to disk.
I use (as suggested by react-css-modules) the ExtractTextPlugin to extract all of the css:
{
test: /\.scss$/,
loader: ExtractTextPlugin.extract('style','css?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]!sass')
}
But if I change this to sourcemaps, as suggested here
loader: ExtractTextPlugin.extract('style', 'css?sourceMap!sass-loader outputStyle=expanded&sourceMap=true&sourceMapContents=true')
I get the error: "root" CSS module is undefined. in my browser console.
You can find my example repo here, but here's the full webpack config I'm using for development.
var webpack = require('webpack');
var path = require('path');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var WriteFilePlugin = require('write-file-webpack-plugin').default;
module.exports = {
entry: {
bundle: [
'webpack/hot/dev-server',
'webpack-hot-middleware/client',
'./index.js'
]
},
devtool: 'cheap-module-source-map',
debug: true,
devServer: devServer,
context: path.resolve(__dirname, './src'),
output: {
path: path.resolve(__dirname, './builds'),
filename: '[name].js',
publicPath: '/builds/'
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.OldWatchingPlugin(),
new WriteFilePlugin(),
new ExtractTextPlugin('[name].css', {
allChunks: true
})
],
module: {
loaders: [
{
test: /\.js$/,
loaders: ['react-hot', 'babel-loader'],
exclude: /node_modules/
},
{
test: /\.scss$/,
loader: ExtractTextPlugin.extract('style','css?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]!sass')
}
]
},
resolve: {
extensions: ['', '.js', '.json']
}
};
How to make the sourcemap work?
Use this:
ExtractTextPlugin.extract('style','css?sourceMap&modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]!sass?sourceMap')
i.e. add the sourceMap param to both css & sass loaders. It said so in sass-loader docs.
This is how I have my css modules set up:
'css-loader?modules&sourceMap&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]!',
I'm totally new to webpack and I'm doing my first configuration for a new project.
I'm trying to load my jsx/scss file but I've this problem:
var path = require('path');
var webpack = require('webpack');
var autoprefixer = require('autoprefixer');
var node_modules_dir = path.resolve(__dirname, 'node_modules');
var ExtractTextPlugin = require("extract-text-webpack-plugin");
var HtmlWebpackPlugin = require('html-webpack-plugin');
var cssExtractTextPlugin = new ExtractTextPlugin("css", "index.css");
var staticPrefix = path.join(__dirname, 'src')
var distPath = path.join(__dirname, 'dist')
module.exports = {
devtool: 'eval',
//context: path.join(__dirname, staticPrefix),
entry: {
'app': ['webpack-hot-middleware/client', path.join(__dirname, 'src/app.jsx')],
'vendor': [
'bootstrap/js/dropdown',
'bootstrap/js/tab',
'bootstrap/js/tooltip',
'bootstrap/js/alert',
'jquery',
'react-router',
'react-bootstrap'
],
'myapp': path.join(__dirname, 'src/stylesheets/base.scss') //'stylesheets/base.scss'
},
output: {

new webpack.ProvidePlugin({

'root.jQuery': 'jquery'
}),
new ExtractTextPlugin('[name].css')
],
module: {
loaders: [

},
postcss: function() {
return [autoprefixer];
},
resolve: {
modulesDirectories: [path.join(__dirname, staticPrefix), 'node_modules'],
extensions: ['', '.jsx', '.js']
},
};
The problem is that when I run: node_modules/.bin/webpack --config=webpack.config.dev it give me 2 errors:
ERROR in ./src/app.jsx

Where I'm doing wrong ?
With babel 6 you need to include the babel react preset to transpile your .jsx files. You also need to add the babel es2015 preset to transpile ES2015, i.e. ES6, syntax:
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /(node_modules)/,
loader: 'babel',
query: {
presets:[ 'react', 'es2015' ]
}
}
]
}
On a side note, if you tweak your regex in the test key, you don't need two loader entries (for the .js and .jsx files).
Make sure you install these presets separately:
npm i -D babel-preset-es2015 babel-preset-react
More info on the babel 6 changes can be found here
