Code splitting is a technique used in web development to split your application’s code into smaller chunks, allowing you to load only the necessary code at runtime. This approach can significantly improve the initial load time of your web application, resulting in a better user experience.
In traditional web development, all the JavaScript code for an application is bundled into a single file, which can become quite large as the application grows in complexity. When a user visits your website, their browser has to download the entire bundle before the application can run. This can lead to slow load times, especially for users with slower internet connections or older devices.
With code splitting, you can divide your application’s code into smaller, more manageable chunks or modules. These modules are then loaded dynamically, on-demand, as the user interacts with your application. This means that the initial load time is reduced because the browser only needs to download the bare minimum code required to render the initial view.
Let’s dive into a practical example to understand how code splitting works in a React application.
