react-css-modules不能正常工作

Question

我想使用react-css- styles.myBtn，但是当我在代码中使用className模块时，我在浏览器中得到了这个类N6OJGonmM2EqyZqImevh，而不是myBtn_。

package.json

  "scripts": {
    "build": "webpack",

    "webpack": "^5.58.2",
    "webpack-cli": "^4.9.1",
    "webpack-dev-server": "^4.3.1"
  }
}

css代码

.myBtn{
  color: blue;
}

Component.jsx

import React from "react";
import styles from "./myBtn.module.css";

const Component=()=>{
  return(
    <div>
      <button className={styles.myBtn}>1234</button>
    </div>
  )
}

export default Component;

如何获取Component_myBtn_XxXx类型的类？

Answer 1

如果您的组件文件名为Component，其代码如下：

const Component=()=>{
  return(
   ...
  )
}

假设在Component旁边有一个css文件，它的内容是：

.myBtn{
  color: blue;
}

因此，css文件应该命名为：Component.module.css。最后，您可以像这样使用它：

import React from "react";
import styles from "./Component.module.css";

const Component=()=>{
  return(
    <div>
      <button className={styles.myBtn}>1234</button>
    </div>
  )
}

export default Component;

我必须在webpack.cofig中添加以下内容

{
        test: /\.css$/,
        use: [
          MiniCssExtractPlugin.loader,
          {
            loader: "css-loader",
            options: {
              importLoaders: 1,
              modules:{
                localIdentName: '[name]__[local]___[hash:base64:5]'
              },
            },
          },
        ],
        include: /\.module\.css$/,
      },
      {
        test: /\.css$/,
        use: [MiniCssExtractPlugin.loader,"css-loader"],
        exclude: /\.module\.css$/,
      },
