带有原因反应的webpack CSS加载器

我正在努力使Webpack与我的理性应用一起工作。

我已经使用以下命令安装了webpack:

npm install --save-dev webpack

我已经使用以下命令安装了style-loader和css-loader:

npm install --save-dev style-loader css-loader

这是我的package.json文件的示例:

 "devDependencies": {
    "bs-platform": "^4.0.18",
    "css-loader": "^2.1.0",
    "html-webpack-plugin": "^3.2.0",
    "style-loader": "^0.23.1",
    "sw-precache-webpack-plugin": "^0.11.5",
    "webpack": "^4.29.3",
    "webpack-cli": "^3.2.3",
    "webpack-dev-server": "^3.1.14",
    "webpack-pwa-manifest": "^4.0.0"
  },
  "dependencies": {
    "react": "^16.8.1",
    "react-dom": "^16.8.1",
    "reason-react": ">=0.5.3"
  }

这是我的webpack.config.js文件的示例:

const outputDir = path.join(__dirname, 'build/');

module.exports = {
  entry: './src/Index.bs.js',
  mode: isProd ? 'production' : 'development',
  output: {
    path: outputDir,
    filename: 'index.js',
    publicPath: PUBLIC_PATH
  },
  module: {
    rules: [{
      test: /\.css$/,
      use: [
        { loader: "style-loader" },
        { loader: "css-loader" }
      ]
    }]
  },

我已将以下命令添加到我的Index.re文件中,以加载我的CSS文件:

[%raw {|require('../css/index.css')|}] 

这是生成的js文件:

// Generated by BUCKLESCRIPT VERSION 4.0.18, PLEASE EDIT WITH CARE
'use strict';

var Component1 = require("./Component1.bs.js");
var ReactDOMRe = require("reason-react/src/ReactDOMRe.js");
var ReasonReact = require("reason-react/src/ReasonReact.js");

((require('../css/index.css')));

ReactDOMRe.renderToElementWithId(ReasonReact.element(undefined, undefined, Component1.make("Hello!", /* array */[])), "index1");

/*  Not a pure module */

启动webpack时没有任何错误,但是我的css文件未在“ build”文件夹中生成... 这是我的项目文件夹:

Project folders

之所以不会生成,是因为style-loader在样式标签上按需添加了html文件头。

要生成物理的CSS文件,请使用mini-css-extract-plugin
