How to extract css styles in webpack

This time I will show you how to extract css styles in webpack, and what are the precautions for extracting css styles in webpack. The following is a practical case, let's take a look.

npm install extract-text-webpack-plugin --save-dev
# for webpack 2
npm install --save-dev extract-text-webpack-plugin
# for webpack 1
npm install --save-dev extract-text-webpack-plugin@1.0.1

First enter the root directory of the project, and then execute the above command to install the plug-in. After the plug-in installation is completed, the next thing we have to do is to introduce the plug-in in webpack.config.js

const ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
 module: {
  rules: [
   {
    test: /\.css$/,
    use: ExtractTextPlugin.extract({
     fallback: "style-loader",
     use: "css-loader"
    })
   }
  ]
 },
 plugins: [
  new ExtractTextPlugin("styles.css"),
 ]
}

const ExtractTextPlugin = require('extract-text-webpack-plugin');
// Create multiple instances 
const extractCSS = new ExtractTextPlugin('stylesheets/[name]-one.css');
const extractLESS = new ExtractTextPlugin('stylesheets/[name]-two.css');
module.exports = {
 module: {
  rules: [
   {
    test: /\.css$/,
    use: extractCSS.extract([ 'css-loader', 'postcss-loader' ])
   },
   {
    test: /\.less$/i,
    use: extractLESS.extract([ 'css-loader', 'less-loader' ])
   },
  ]
 },
 plugins: [
  extractCSS,
  extractLESS
 ]
};

The plug-in has three parameters with the following meanings

1. use: refers to what kind of loader is needed to compile the file. Since the source file is .css, css-loader is selected here

2. fallback: What loader is used to extract the css file after compilation

3. publicfile: used to overwrite the project path and generate the file path of the css file
