使用dynamic import可以把打包的文件分成两个,一个仅仅包含展示<StockTable />才需要的代码的main文件、一个仅仅包含展示<StockChart />才需要的代码及依赖的文件。 这个技术如此有用,以至于React 16.6增加了一个API:React.lazy(), 使得它更易结合React组件使用。 为了使用React.lazy(),我们需要更改App.js的两个地...
In the context of React, this technique is particularly useful for large or resource-intensive components, such as images, videos, or sections of a webpage that are not immediately visible when the page loads. By deferring the loading of these non-essential resources, you can significantly impr...
React, the “leader” in this space at the moment, is not without blame here. Big and bloated components with unused code chunks are often bottlenecks in performance when being downloaded or executed in the browser. One way to address this challenge is throughlazy loading, an optimization techn...

同时,React.lazy() 组件需要在 React.Suspense 组件下进行渲染,Suspense 又支持传入 fallback 属性,作为动态加载模块完成前组件渲染的内容。 回到系列文章开头的例子: import Loading from './components/loading'; const MyComponent: React.FC<{}> = () => { const [Bar, setBar] = useState(null); const...

To understand lazy loading in React, we need to think in two steps. 1. Use dynamice import: to load script 2. Use React.lazy to load dynammice import, it will hook up with a component constloadGlobe = () =>import('../globe')constGlobe = React.lazy(loadGlobe) ...
This was all about how to implement lazy loading in react, if you need the fallback feature, you can update HOC's render method where it is returning null. Instead of null, you can return your fallback component, and it can be passed as props too. ...
