海外TECH	DEV Community	Implement Code Splitting in React	https://dev.to/damcosset/implement-code-splitting-in-react-1c0j	Implement Code Splitting in React Understanding React bundlingBy using tools such as Webpack or Browserify React applications are bundled Bundled means that the files inside your application are imported and merged into one file This way when you import your application in a webpage you only need to import one file Assuming you have two files greeting jsexport const greeting gt console log Hello my friend index jsimport greeting from greeting js greeting A bundle would transform these files into const greeting gt console log Hello my friend greeting Of course this is oversimplified because there are a lot of steps in the bundling process but you get the idea Bundling issueBundling is great when your application is small but as your application grows the bundle grows as well That means if a user loads the home page of your web app she will still have to import the bundle of your ENTIRE application This can cause performance issues To avoid this we can implement code splitting In this article we will use code splitting based on our routes import Code splitting implies that we will have our code into smaller pieces Yet we won t need to change the way our code is written We will change the way we import our components We need to tell the tool in charge of bundling our code when to split our code If you use create react app which uses Webpack you will start by using the dynamic import function The syntax goes as follow import myModule js then myModule gt myModule init The syntax uses a promise to wait for the Javascript file to be loaded before using the content of the file React lazyReact implements this sort of logic with React lazy It allows you to display a component just like any other component the difference being that it will be imported dynamically import React lazy from react const DynamicallyImported lazy gt import DynamicallyImported js React lazy takes a function that returns a dynamic import This component will not be imported with the rest of the application like you would without any code splitting implemented React will import this component only when it is rendered for the first time Note that the component that you dynamically import needs to be a default export and of course it needs to export a React component So if we implement code splitting based on our routes this means that if a user checks our application and never travels to a particular route that route won t be imported at all A huge benefit for your user as you will only force her browser to import exactly what he needs and nothing more SuspenseA component imported with React lazy must be used inside a Suspense component A Suspense component provides a fallback content This content acts an indication that our lazy component is loading import React lazy Suspense from react const DynamicallyImported lazy gt import DynamicallyImported js const CoolComponent gt return lt div gt lt Suspense fallback lt div gt Loading lt div gt gt lt DynamicallyImported gt lt Suspense gt lt div gt Such dynamically imported components don t need to be directly surrounded by a Suspense component One Suspense component can also handle several dynamically imported components import React lazy Suspense from react const DynamicallyImported lazy gt import DynamicallyImported js const AnotherDynamicallyImported lazy gt import AnotherDynamicallyImported js const CoolComponent gt return lt div gt lt Suspense fallback lt div gt Loading lt div gt gt lt header gt lt h gt Hello there lt h gt lt header gt lt div gt Something else lt div gt lt DynamicallyImported gt lt p gt Divider lt p gt lt AnotherDynamicallyImported gt lt Suspense gt lt div gt Code splitting based on our routesRoutes are a good place to start implementing code splitting Going from one page to another users are expecting the page to load as a block and to wait a bit for the page to be rendered It makes it a good place to start while being sure to not alter the user experience In this example I ll use the popular react router dom package for the routing of my React application Of course it can be used with any library you prefer Before code splitting your Router component could look something like this import React from react import Route Router Switch from react router dom import Header from Header import About from pages About import Blog from pages Blog import Contact from pages Contact import Home from pages Home import Products from pages Products import createBrowserHistory from history const history createBrowserHistory export default gt return lt Router history history gt lt Header gt lt Switch gt lt Route exact path component Home gt lt Route path about component About gt lt Route path products component Products gt lt Route path blog component Blog gt lt Route path contact component Contact gt lt Switch gt lt Router gt If you ve used react router dom before this will be familiar If not this is how routing is implemented using this library With this code whenever a user travels to one page the entire application code will be loaded Because we have only one bundle there can t be any other way This can be expensive We ll need to do three things to make code splitting work and having several bundles Import React lazy and Suspense Modify how we import our components Home About Products Blog and Contact to make it dynamic using React lazy and import Use the Suspense component to provide a fallback in our return function You would change the first line to import React lazy Suspense from react Done Import dynamically our components Change line to like so const About lazy gt import pages About const Blog lazy gt import pages Blog const Contact lazy gt import pages Contact const Home lazy gt import pages Home const Products lazy gt import pages Products Awesome Finally surround the components dynamically imported with the Suspense component export default gt return lt Router history history gt lt Header gt lt Suspense fallback lt div gt Loading page lt div gt gt lt Switch gt lt Route exact path component Home gt lt Route path about component About gt lt Route path products component Products gt lt Route path blog component Blog gt lt Route path contact component Contact gt lt Switch gt lt Router gt Fantastic You have successfully implemented code splitting in your React application Your users are happy with the newfound speed of their application Time to celebrate I am using create react app which uses Webpack If I run npm run build after implementing code splitting I can see that Webpack is creating different bundles now More files but smaller files And that s the point Hope it was clear enough If not as always don t hesitate to ask questions in the comments Have fun ️	2020-05-21 18:36:57
