Firstly, to clarify your question, you're asking about strategies for implementing code splitting and dynamic imports in a React application that's rendered on the server side. This involves loading only the necessary code to the client at runtime, thus optimizing performance. My strategy leverages React's built-in support for dynamic imports via React.lazy and Suspense, in conjunction with the @loadable/component library which enhances SSR compatibility.
Dynamic Imports in React: React's React.lazy function allows us to render a dynamic import as a regular component. Suspense components can then wrap lazy components, enabling us to specify a loading state (a fallback component) while we're waiting for the lazy component to load. However, React.lazy and Suspense do not out-of-the-box support server-side rendering....
