chunks are larger than 500 kB after minification
Hello, I have a Nuxt application and everything works perfectly, but I’ve been focusing on optimizations lately. I was checking the build, and it gives that warning: “Some chunks are larger than 500 kB after minification.”
Is there any article, best practices, or place where I can study this type of optimization?

Yes, there are official Nuxt resources and best practices to help you optimize your application and address warnings about large chunks after minification.
The Nuxt documentation provides a dedicated performance best practices guide that covers built-in features, profiling tools, and common problems related to performance. It specifically recommends using tools like Nuxi Analyze to visualize your production bundle and identify large blocks that could be split, lazy-loaded, or optimized by importing only the necessary components instead of entire modules. This helps reduce chunk sizes and improve overall performance. The guide also links to external resources on instant loading, perceived performance, and the critical rendering path for deeper study Nuxt performance.
Additionally, the guide highlights common issues such as overusing plugins, unused code, and not leveraging Vue performance tips, all of which can contribute to unnecessarily large bundles. Addressing these can help reduce your chunk sizes and improve your build output Common problems.
For practical steps:
- Use dynamic imports to split large chunks.
- Analyze your bundle with Nuxi Analyze or similar tools.
- Remove unused dependencies and code.
- Import only what you need from third-party libraries.
You can find all these recommendations and more in the Nuxt performance best practices documentation.
