問題描述

我創建了包含 7 個頁面和 13 個組件的非常簡單的 react 應用程序.我正在使用 gulp 編譯它，browserify 用于依賴項，所有文件都被最小化.

I created pretty simple react application containing 7 pages and 13 components. I am using gulp to compile it, browserify for dependencies, all files are minimized.

我構建的 app.js 文件有 1.1 MB.我覺得挺大的.

My build'ed app.js file has 1.1 MB. I think it is quite big.

我能做些什么來減小它的大小?有沒有什么好的做法可以實現最小尺寸?

What can I do to reduce its size ? Are there any good practices to achieve smallest size ?

我沒有依賴的源代碼是91 KB.

My source code without dependencies is 91 KB.

推薦答案

使用 webpack-uglify 并禁用 source maps 可以極大地提高輸出到合理的大小(對于 hello world 應用程序約為 140kbs)

Using webpack-uglify and disabling source maps can greatly improve the output to a reasonable size (~140kbs for a hello world application)

幾個步驟:

將 webpack 配置中的 devtool 設置為 cheap-source-map 或 cheap-module-source-map 以便不捆綁源映射輸出:

Setting devtool in webpack config to cheap-source-map or cheap-module-source-map so the source maps are not bundled with the output:

{
  eval: 'cheap-source-map'
}

激活 uglify 插件或使用 -p 參數調用 webpack

Activate uglify plugin or call webpack with -p argument

plugins: [
  new webpack.optimize.UglifyJsPlugin({
    compress: {
      warnings: false
    }
  })
]

為生產定義節點環境導致 webpack 刪除測試助手并優化輸出大小:

Defining node environment for production causes webpack to remove test helpers and optimize the ouput size:

plugins: [
  new webpack.DefinePlugin({
    'process.env': {
      'NODE_ENV': JSON.stringify('production')
    },
  })
]

注意:這些步驟應僅用于生產構建，因為它們會增加構建時間.

Note: these steps should be only used for production builds as they increase the build time.
