webpack的loader

Posted 2020-09-23

抽离css样式,打包好的css文件，自动添加到<link>里
防止将样式打包在js中引起页面样式加载错乱的现象;首先我先来介绍下这个插件的安装方法:

npm install extract-text-webpack-plugin --save-dev

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"),
  ]
}
