目前没有配置加载器来处理这个文件

Question

我有一个 TypeScript(TS) React 项目，我用它来保存我的所有 React 组件。我正在从这个项目中创建一个 NPM 包，然后在单独的 React 项目中使用它。为了解决之前的 .css 和图像文件不属于我的包的问题，​​我现在尝试实现 Webpack，但我的知识确实存在漏洞。

尝试运行 webpack 时出现多个类似错误：
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file.

我已经安装了所有我认为必要的加载器：

• 样式加载器
• ts-loader
• 文件加载器

webpack.config.js

const path = require('path');

module.exports = {
    entry: './src/index.ts',
    devtool: 'inline-source-map',
    module: {
        rules: [
        {
            test: /\.tsx?$/,
            use: 'ts-loader',
            exclude: /node_modules/,
        },
        ],
    },
    resolve: {
        extensions: [ '.tsx', '.ts', '.js' ],
    },
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, 'dist'),
    },
    module: {
        rules: [
            {
                test: /\.css$/,
                use: [
                    'style-loader',
                    'css-loader'
                ]
            },
            {
                test: /\.(png|svg|jpg)$/,
                use: [
                    'file-loader',
                ],
            },
        ]
    }
};

我通过反复试验发现了问题。 webpack.config.js 对两个单独的模块部分不满意。

以下是成功捆绑的配置。

webpack.config.js

const path = require('path');

module.exports = {
    entry: './src/index.ts',
    devtool: 'inline-source-map',
    module: {
        rules: [
            {
                test: /\.css$/,
                use: [
                    'style-loader',
                    'css-loader'
                ]
            },
            {
                test: /\.(png|svg|jpg)$/,
                use: [
                    'file-loader',
                ],
            },
            {
                test: /\.tsx?$/,
                use: 'ts-loader',
                exclude: /node_modules/,
            },
        ]
    },
    resolve: {
        extensions: [ '.tsx', '.ts', '.js' ],
    },
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, 'dist'),
    },
};
