我创建了包含 7 个页面和 13 个组件的非常简单的 react 应用程序.我正在使用 gulp 编译它,browserify 用于依赖项,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.
我构建的 app.js 文件有 1.1 MB.我觉得挺大的.
My build'ed app.js file has 1.1 MB. I think it is quite big.
我能做些什么来减小它的大小?有没有什么好的做法可以实现最小尺寸?
What can I do to reduce its size ? Are there any good practices to achieve smallest size ?
我没有依赖的源代码是91 KB.
My source code without dependencies is 91 KB.
推荐答案使用 webpack-uglify 并禁用 source maps 可以极大地提高输出到合理的大小(对于 hello world 应用程序约为 140kbs)
Using webpack-uglify and disabling source maps can greatly improve the output to a reasonable size (~140kbs for a hello world application)
几个步骤:
将 webpack 配置中的 devtool 设置为 cheap-source-map 或 cheap-module-source-map 以便不捆绑源映射输出:
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 参数调用 webpack
Activate uglify plugin or call webpack with -p argument
plugins: [ new webpack.optimize.UglifyJsPlugin({ compress: { warnings: false } }) ]为生产定义节点环境导致 webpack 删除测试助手并优化输出大小:
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:这些步骤应仅用于生产构建,因为它们会增加构建时间.
Note: these steps should be only used for production builds as they increase the build time.
