「排除」通天裝載機的選項的WebPack

 

    module.exports = { 
     entry: './index.js', 
     output: { 
      filename: 'index.min.js', 
      path: './' 
     }, 
     module: { 
      loaders: [ 
       { 
        test: /\.js$/, 
        loader: 'babel', 
        exclude: /node_modules/, 
        query: { 
         presets: ['es2015'], 
         plugins: ['transform-runtime'] 
        }, 
        cacheDirectory: true 
       } 
      ] 
     } 
    }

 

    const pi = 3.14159265; 

    let s = "Hello"; 

    for (let codePoint of s) { 
     console.log(codePoint); 
    }

當我刪除的「排除」行了，編譯後的文件變成大約兩倍，它拋出錯誤：「$擴展是不是一個函數」。「排除」通天裝載機的選項的WebPack

我想知道爲什麼排除選項對編譯過程有影響。我只編譯./index.js

這就是導致這種行爲的transform-runtime插件 - 如果您將它放開，大小是相同的。

爲了找到問題的根源，我創建了兩個配置，其中一個排除了node_modules，另一個排除了您的問題。此外，我讓的WebPack生成源Maps（網絡包的-d參數/ devtool：「源圖」配置），看着包含文件不出現在排除版本（簡單差異）。這些都是

的transform-runtime插件處理這些文件，所以他們都包含在構建時，不排除node_modules。
