why material-ui takes too much space? - reactjs

Question

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 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 = {

app: './app/index.jsx',

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.

Answer 1

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.

Answer 2

There are a couple of things you could do to reduce the size:
Make sure you are only requiring in the components you need from material-ui and not the whole library
Try using Minifyify
See more suggestions in this GitHub Issue.

Answer 3

I would go for Option 2 listed in their documentation here: Minimizing Bundle Size. They suggest this provides a much better experience for both developers and users, I think with much faster loading times for both.
Setup your Babel configuration with babel-plugin-import or babel-plugin-transform-imports. These configurations make sure only the files that you use from Material-UI are included in your builds.
Convert all you Material-UI import statements as such:
-import Button from '#material-ui/core/Button';
-import TextField from '#material-ui/core/TextField';
+import { Button, TextField } from '#material-ui/core';
