Next.js: 3 Tips for Turbo Speed

In an era of instant gratification, a slow site is a dead site. Three seconds of waiting and the user is lost. No engineering degree needed, just three key principles.

1. Images: The Serial Killer

The performance serial killer. Uploading 4K photos for mobile is criminal. The solution is Next.js <Image />: it automatically resizes and converts to WebP/AVIF. A personal assistant optimizing every pixel.

2. Code Splitting

Downloading huge libraries for trivial tasks is like renting a truck for a letter. Import only essentials. Code Splitting is the necessary diet: load heavy parts only when truly needed.

3. Server Components

The Client (browser) shouldn't cook, it should just eat. With Server Components, the meal arrives ready (pure HTML), light and fast. Moving heavy logic to the server is the only way to fly.

Conclusion

Speed isn't magic, it's discipline: cutting fat until only the essential remains.
