The evolution of web rendering. From PHP (MPA) to React (SPA), back to Next.js (SSR/SSG). Deep dive into hydration cost and Server Components.
Fast by name. Partitioning around a Pivot. Why is it the standard library choice despite O(N²) worst case?
Tired of naming classes? Writing CSS directly inside HTML sounds ugly, but it became the world standard. Why?
Establishing TCP connection is expensive. Reuse it for multiple requests.
A comprehensive deep dive into client-side storage. From Cookies to IndexedDB and the Cache API. We explore security best practices for JWT storage (XSS vs CSRF), performance implications of synchronous APIs, and how to build offline-first applications using Service Workers.
After using Next.js for over a year, I've learned this:
"Rendering strategy is about balancing business requirements and costs."And this choice can vary by page, even by component. Next.js's real strength is this flexibility.
I started with a simple understanding of "Next.js is an SSR framework," but now I think of it as "Next.js is the Swiss Army knife of web rendering." You just pick the right tool for the situation.
Finally, RSC is a true game changer. Bundle size reduction, hydration optimization, simplicity of backend integration. It's still in the stabilization phase, but I'm convinced it will become the standard for web development.
The most impactful realization from this process was "technology is about tradeoffs." There's no silver bullet. Choose based on the situation, measure, and improve. That's the developer's job, and that's what I came to understand.
