Notes on Building Fast Web Apps with Next.js

Practical patterns for keeping your App Router architecture simple, static-friendly, and easy to maintain.

Text size

The best performance optimization is shipping less JavaScript by default. Server Components let you render rich content pages without hydrating static text in the browser.

Keep your data layer decoupled from your UI components. Even when starting with local TypeScript files, wrapping reads in clean helper functions makes migrating to MDX or a CMS trivial later.

Focus on fast feedback loops: strict TypeScript types, semantic HTML, and minimal utility classes go a long way.
