Webpack 5 没有在.js文件中加载图像

Question

I'm making a module that I have to test through the third party site.

everything works fine except the Webpack won't build any image files that I add inside the .js files. I can't import the images because there is too many and they are being selected by a variable. I can't figure out why the images won't build.

I have also tried file-loader and url-loader, nothing works.

The return in the react file

return (<div><img src="/src/images/screenshot.png" /></div> )

Here is the config:

module.exports = {
    mode: isProd ? "production" : "development",
    entry: "./src/index.js",
    module: {
        rules: [

{ test: /.(jpe?g|png|svg|gif|ico|eot|ttf|woff|woff2|mp4|mp3|pdf|webm|txt)$/i, use: [ { loader: "file-loader", }, ], }, { test: /.(jpe?g|png|svg|gif|ico|eot|ttf|woff|woff2|mp4|mp3|pdf|webm|txt)$/, type: "asset/resource", generator: { filename: "static/chunks/[path][name].[hash][ext]", }, },

            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: {
                    loader: "babel-loader",
                    options: {
                        plugins: [
                            "syntax-dynamic-import",
                            "transform-react-jsx",
                        ],
                    },
                },
            },
            {
                test: /\.(css|scss|sass)$/,
                use: ["style-loader", "css-loader", "sass-loader"],
            },
        ],
    },
    plugins: [
        new webpack.DefinePlugin({
            __PUBLIC_PATH__: JSON.stringify(publicPath),
        }),
    ],
    output: {
        filename: "[name].js",
        chunkFilename: "[name].chunk.js",
        path: buildPath,
        publicPath,
    },
    devServer: {
        static: {
            directory: buildPath,
            watch: true,
        },
        historyApiFallback: true,
        headers: {
            "Access-Control-Allow-Origin": "*",
        },
        client: {
            logging: "log",
            reconnect: false,
            webSocketURL: "ws://localhost:8080",
        },
    },
};

For images to be processed by webpack, you should use file-loader

Install it with $ npm install file-loader --save-dev .

Then add this rule to your webpack config:

    rules: [
      {
        test: /\.(jpe?g|png|svg|gif|ico|eot|ttf|woff|woff2|mp4|mp3|pdf|webm|txt)$/i,
        use: [
          {
            loader: 'file-loader',
          },
        ],
      },
    ],
