Webpack-dev-server 不生成源映射

Webpack-dev-server doesn't generate source maps

我使用 babel-loader,但无法弄清楚如何生成或在哪里可以找到转译文件的源映射。我尝试了 eval-source-mapinline-source-mapsource-map

webpack.config.js

const BowerWebpackPlugin = require("bower-webpack-plugin");

module.exports = {
    entry: './src/script/index.jsx',
    output: {
        filename: 'bundle.js',
        sourceMapFilename: "bundle.js.map",
        publicPath: 'http://localhost:8090/assets'
    },
    debug: true,
    devtool: 'inline-source-map',
    module: {
        loaders: [
            {   
                test: /\.js[x]?$/, 
                loaders: ['react-hot', 'jsx', 'babel'],
                exclude: /node_modules/ 
              },
              {
                test: /\.scss$/,
                loaders: [ 'style', 'css?sourceMap', 'sass?sourceMap' ]
              },
              {
                test: /\.less$/,
                loaders: [ 'style', 'css?sourceMap', 'less?sourceMap' ]
              },
              {
                test: /\.css$/,
                loaders: [ 'style', 'css']
              },
              { test: /\.woff$/,   loader: "url-loader?limit=10000&mimetype=application/font-woff" },
              { test: /\.woff2$/,   loader: "url-loader?limit=10000&mimetype=application/font-woff2" },
              { test: /\.(eot|ttf|svg|gif|png)$/,    loader: "file-loader" }
        ]
    },
    plugins: [
        new BowerWebpackPlugin()
    ],
    externals: {
        //don't bundle the 'react' npm package with our bundle.js
        //but get it from a global 'React' variable
        'react': 'React'
    },
    resolve: {
        extensions: ['', '.js', '.jsx']
    }
}

编辑://

毕竟这 webpack.config.js and this package.json 适合我。

edit2://

现在我用this webpack config

使用webpack -d

d 标志代表开发快捷方式,它启用所有开发人员工具,例如源映射。

{devtool:"source-map"} 添加到您的 webpack.config.js

查看更多here

使用webpack-dev-server -d

  • -d 是 shorthand 对于 --debug --devtool source-map --output-pathinfo
  • output-pathinfo 向生成的包添加注释,解释 module/files 包含在哪些地方。所以在生成的代码中,注释被添加到这行代码:require(/* ./test */23) 表示 23 指向 test 模块。当您查看 Webpack 生成的代码时,这非常有用,而在单步执行调试器时则用处不大。我得到了这个例子 from this relevant bit of documentation.

  • 这一切都有效,因为 webpack-dev-server 接受与 webpack 所有相同的标志。

  • See this section in the docs 了解详情。

提示与陷阱

  • --content-base - 默认情况下,开发服务器将在您 运行 命令所在的目录中提供文件。如果您的构建文件在 build/ 中,则需要指定 --content-base build/ 所以开发服务器将在 build 目录
  • 中提供文件
  • --inline - 每当您保存有一些更改的文件时自动重新加载!

请在您的webpack.config.js文件中添加以下内容`

devtool: "#inline-source-map",

你可以从webpack的网站上找到关于它的明确信息` https://webpack.github.io/docs/configuration.html

另请从 webpack 站点找到源映射部分的附加屏幕截图。

我所做的只是改变:

// package.json
{
    ...
    **from** "dev:serve": "webpack-dev-server",
    **to** "dev:serve": "webpack-dev-server -d",
    ...
}

相当于:$ webpack-dev-server -d

现在我可以在 Chrome 中使用 Ctrl + p 并且我看到了我的 ES6 语法来设置断点。
