为什么material-ui占用太多空间? [英] why material-ui takes too much space?

问题描述

我正在使用webpack捆绑我的React项目.我的项目取决于material-ui的以下组件:

I am using webpack to bundle my react project. My project depends on material-ui for below component:

material-ui/Dialog
material-ui/styles/getMuiTheme
material-ui/styles/MuiThemeProvider
material-ui/FlatButton
material-ui/TextField

webpack-bundle-size-analyzer报告material-ui占用1.07MB的大小.以下是我的webpack配置文件:

webpack-bundle-size-analyzer reports material-ui takes 1.07MB size. Below is my webpack config file:

const webpack = require('webpack');
const path = require('path');
const NpmInstallPlugin = require('npm-install-webpack-plugin');
const WebpackShellPlugin = require('webpack-shell-plugin');
var CompressionPlugin = require("compression-webpack-plugin");

const PATHS = {
  react: path.join(__dirname, 'node_modules', 'react', 'dist', 'react.min.js'),
  app: path.join(__dirname, 'src'),
  build: path.join(__dirname, './dist')
};

module.exports = {
  entry: {
    app: './app/index.jsx',
    android: './app/utils/platform_android.js',
    ios: './app/utils/platform_ios.js',

    new CompressionPlugin({
      asset: "[path].gz[query]",
      algorithm: "gzip",
      test: /\.js$|\.html$/,
      threshold: 10240,

    new webpack.optimize.CommonsChunkPlugin(/* chunkName= */["vendor"], /* filename= */"[name].bundle.js", Infinity),
  ],
  devServer: {
    colors: true,
    contentBase: __dirname,
    historyApiFallback: true,

    inline: true,
    port: 9093,
    progress: true,
    stats: {
      cached: false
    }
  }
}

我已经尝试使用CompressionPlugin，UglifyJsPlugin来优化我的捆绑文件，但仍然需要1MB以上的内存.如何缩小尺寸?我不想使用gzip，因为我的应用程序在移动设备上的webview上运行，并且其中一些不支持gzip编码.

I already tried to use CompressionPlugin, UglifyJsPlugin to optimize my bundle files but it still takes more than 1MB. How can I reduce its size? I don't want to use gzip since my app is running on webview on mobile device and some of them doesn't support gzip encoding.

推荐答案

最后，我弄清楚了问题所在.在我的webpack配置文件中，我将所有供应商js分离到另一个js捆绑文件中.我在那里列出了"material-ui".打包我的应用程序时，整个"material-ui"库将打包到vendor.js中.我必须从供应商列表中删除material-ui，通过这种方式，仅打包我的源代码所需的组件.

Finally I figured out what the problem. In my webpack config file, I separate all vendor js into a different js bundle file. And I listed 'material-ui' there. When package my app, the whole 'material-ui' library will be packaged into vendor.js. I have to remove the material-ui from vendor list, in this way only the components required by my source code will be packaged.
