What are the best practices for code splitting in web development?

Code splitting is a technique to split your code into smaller chunks, which can be loaded on demand. Best practices include using dynamic imports, leveraging libraries like React.lazy, and analyzing bundle sizes.

How do I implement dynamic imports in my project?

You can implement dynamic imports using the import() function. For example, instead of importing a module at the top, you can do it inside a function or a component.

What tools can help me analyze my bundle sizes?

Tools like Webpack Bundle Analyzer, Source Map Explorer, and Lighthouse can help you analyze and visualize your bundle sizes.

Are there any performance implications of code splitting?

Yes, while code splitting can improve initial load times, it may introduce additional network requests. It's important to balance the number of chunks.

Can you give examples of when to use code splitting?

Sure! Use code splitting for large libraries, routes in single-page applications, or components that are not always needed at startup.
