海外TECH	DEV Community	Minimizing Webpack bundle size	https://dev.to/useanvil/minimizing-webpack-bundle-size-38gg	Minimizing Webpack bundle size The dreaded loading spinnerThe two key metrics in determining whether users will stay on your site is the time it takes to load the page and the time it takes to interact with it The first is First Contentful Paint and the second is Time to Interactive You can find these metrics for your own site by going to your developer tools and generating a report under the Lighthouse tab on Chrome Lighthouse metrics for a random web appBy minimizing the size of the bundle we reduce the time it takes for browsers to download the JavaScript for our site improving user experience With every additional second of wait time the user is more likely to close the tab Consider all of the users that visit your site everyday and that can be thousands of seconds wasted The chance of losing a potential user is even higher when you have a complex web app making it even more important to ensure the bundle size stays low Understanding the situationLet s start by getting an understanding of all the code amp dependencies that need to be sent to the browser along with the memory size of each Adding webpack bundle analyzer to your webpack configuration is the perfect starting point Install yarn add D webpack bundle analyzer ornpm install save dev webpack bundle analyzerUsage import WebpackBundleAnalyzer from webpack bundle analyzer webpackConfig plugins new WebpackBundleAnalyzer BundleAnalyzerPlugin After compiling your bundle your browser should open up a visualization of all the content and its memory sizes Visualization of the bundle Tree shakingWebpack works by building a dependency graph of every module imported into our web app traversing through files containing the code we need and bundling them together into a single file As our app grows in complexity with more routes components and dependencies so does our bundle When our bundle size exceeds several MBs performance issues will arise It s time to consider tree shaking as a solution Tree shaking is a practice of eliminating dead code or code that we ve imported but do not utilize Dead code can vary from React components helper functions duplicate code or svg files Let s go through ways of reducing the amount of dead code we have with help from some Webpack plugins babel plugin importThe babel plugin import plugin for babel loader enables Webpack to only include the code we need when traversing through dependencies during compilation instead of including the entire module This is especially useful for heavy packages like antd and lodash More often than not web apps only need select UI components and helper functions so let s just import what s needed Install yarn add D babel plugin import ornpm install save dev babel plugin importUsage webpackConfig module rules test js jsx include path resolve dirname src client use loader babel loader options plugins modularly import the JS and styles that we use from antd import libraryName antd style true antd modularly import the JS that we use from ant design icons import libraryName ant design icons libraryDirectory es icons antd icons We instantiated two instances of babel plugin import one for the antd package and the other for the ant design package Whenever Webpack encounters import statements from those packages it is now selective in terms of what part of the package to include in the bundle import Dropdown from antd transforms tovar dropdown require antd lib dropdown babel plugin lodashSimilar to babel plugin import the babel plugin lodash plugin cherry picks the code we need to import from lodash The parsed size of the entire lodash package is KB so we definitely don t want everything Install yarn add D babel plugin lodash ornpm install save dev babel plugin lodashUsage webpackConfig module rules test js jsx include path resolve dirname src client use loader babel loader options plugins modularly import the JS that we use from lodash lodash presets babel env targets node If you re already using babel plugin import for lodash this may be unnecessary but it s always nice to have alternatives import from lodash const objSize size a b c transforms toimport size from lodash size const objSize size a b c context replacement pluginLooking at the visual of bundle js the locale data in the moment package already makes up KB In the case that no locale functionality is used we should remove that portion of the package from the bundle Webpack s ContextReplacementPlugin is the best way to do this KB totalimport webpack from webpack only include files matching en in the moment locale contextwebpackConfig plugins push new webpack ContextReplacementPlugin moment locale en A quick look at the bundle analyzer visualization shows that this simple plugin already shaves KB off our bundle size A very quick win KB total moment timezone data webpack pluginIf you re using moment timezone in your app you ll find moment timezone data webpack plugin extremely useful Moment timezone includes a comprehensive json file of all timezones for a wide date range which results in a package size of KB As with locales it s highly likely we don t need this large data set so let s get rid of it This plugin helps us do that by customizing the data we want to include and stripping out the rest Install yarn add D moment timezone data webpack plugin ornpm install save dev moment timezone data webpack pluginUsage import MomentTimezoneDataPlugin from moment timezone data webpack plugin only include timezone data starting from year to in AmericawebpackConfig plugins push new MomentTimezoneDataPlugin startYear endYear matchZones America A before and after analysis shows the package size shrinking to KB from KB Code splittingA major feature of Webpack is code splitting which is partitioning your code into separate bundles to be loaded on demand or in parallel There are a couple ways code splitting can be done through Webpack one of which is having multiple entry points and another is having dynamic imports We ll be focusing on dynamic imports PolyfillsA fitting use case for code splitting is polyfills since they re only neccessary depending on the browser We don t know in advance whether a polyfill would be required until the client fetches the bundle and thus we introduce dynamic imports In cases where a dependency is used for something that is already supported by some browsers it may be a good idea to drop the dependency use the native function supported by most browsers and polyfill the function for browsers that don t support it One example is getting the timezone import moment from moment timezone moment tz guess works the same asIntl DateTimeFormat resolvedOptions timeZoneIf we get Intl DateTimeFormat resolvedOptions timeZone polyfilled on the older browsers we can completely drop moment timezone as a dependency reducing our bundle size by an extra KB Let s start by adding the polyfill as a dependency yarn add date time format timezone ornpm install date time format timezoneWe should only import it if the browser does not support it if Intl DateTimeFormat resolvedOptions timeZone import webpackChunkName “polyfill timezone date time format timezone then module gt module default As Webpack traverses through the code during compilation it ll detect any dynamic imports and separate the code into its own chunk We ve accomplished two things reducing the size of the main bundle and only sending the polyfill chunk when necessary Frontend routesFor complex web apps that can be divided into sections route based code splitting is a clear solution For example a website may have an e commerce section and an about the company section Many users who visit the site only interact with the e commerce pages so loading the other sections of the web app is unnecessary Let s reduce our bundle size by splitting our main bundle into many bundles to be loaded on demand If you re using React good news because route based code splitting is pretty intuitive in this framework Like with the example shown earlier dynamic imports is used to partition the app into separate bundles import React Suspense lazy from react import BrowserRouter Route Switch from react router dom import LoadingScreen from components LoadingScreen const App props gt lt BrowserRouter gt lt Suspense fallback lt LoadingScreen gt gt lt Switch gt lt Route exact path component lazy gt import routes landing gt lt Route path shop component lazy gt import routes shop gt lt Route path about component lazy gt import routes about gt lt Switch gt lt Suspense gt lt BrowserRouter gt Once we have this code in place Webpack will take care of the bundle splitting Removing duplicate dependenciesDuplicate dependencies arise when dependencies with overlapping version ranges exist This generally happens due to the deterministic nature of yarn add and npm install As more dependencies are added the more likely duplicate packages are installed This leads to an unnecessarily bloated size of your web app and bundle Fortunately there are tools for this If you re using yarn version or greater you can skip this as yarn has taken care of it automatically These tools work by moving dependencies with overlapping version ranges further up the dependency tree enabling them to be shared by multiple dependent packages and removing any redundancies If you re using yarn x yarn global add yarn deduplicateyarn deduplicate yarn lockOr if you use NPM npm dedupe Upgrading and removing dependenciesLook at the bundle visual again and check if the large dependencies support tree shaking and whether there is a similar but smaller package that does everything you need Upgrading dependencies frequently is recommended as package size usually slims down over time and as tree shaking is introduced Lastly production modeMake sure Webpack is in production mode on release Webpack applies a number of optimizations to your bundle including minification with TerserWebpackPlugin if you re using Webpack v or above If not you ll have to install and add it manually Other optimizations include omitting development only code and using optimized assets SummaryWe ve covered the importance of bundle size analyzing the composition of a bundle tree shaking code splitting dependency deduplication and various Webpack plugins to make our lives easier We also looked into dynamic imports and loading code on demand With these practices introduced into your webpack config js file you can worry less about those dreaded loading spinners We ve applied these practices to our code at Anvil and
