React Loadable vs React Lazy

Developers should use React Loadable when building large React applications where reducing the initial bundle size is critical for performance, such as in single-page applications (SPAs) or progressive web apps (PWAs) meets developers should use react lazy when building large react applications where initial bundle size impacts performance, such as in spas with many routes or complex features. Here's our take.

React Loadable

Nice Pick

Developers should use React Loadable when building large React applications where reducing the initial bundle size is critical for performance, such as in single-page applications (SPAs) or progressive web apps (PWAs)

Pros

• It is particularly useful for optimizing load times on slow networks or mobile devices, and when implementing features like route-based or component-based code splitting to enhance user experience
• Related to: react, code-splitting

Cons

• Specific tradeoffs depend on your use case

React Lazy

Developers should use React Lazy when building large React applications where initial bundle size impacts performance, such as in SPAs with many routes or complex features

Pros

• It is ideal for lazy-loading components that are not immediately required, like modals, tabs, or route-based components, to enhance user experience by speeding up the first contentful paint
• Related to: react-suspense, code-splitting

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use React Loadable if: You want it is particularly useful for optimizing load times on slow networks or mobile devices, and when implementing features like route-based or component-based code splitting to enhance user experience and can live with specific tradeoffs depend on your use case.

Use React Lazy if: You prioritize it is ideal for lazy-loading components that are not immediately required, like modals, tabs, or route-based components, to enhance user experience by speeding up the first contentful paint over what React Loadable offers.

The Bottom Line

React Loadable wins

Developers should use React Loadable when building large React applications where reducing the initial bundle size is critical for performance, such as in single-page applications (SPAs) or progressive web apps (PWAs)
