Episode notes
Next.js Is A Server-First React Framework
- Next.js is a backend framework that serves React applications and generates HTML on the server for initial loads.
- Server-rendered HTML enables pages to display content even with client JavaScript disabled, improving UX and SEO.
Avoid getServerSideProps As Default
- Avoid overusing getServerSideProps for most pages because it couples data-fetching to the page and has rough edges.
- Prefer safer, component-level fetching strategies when possible to keep data boundaries clear and maintainable.
Dev Mode Double Renders Enforce Robustness
- React's dev-mode double renders are intentional to simulate interrupted renders and enforce cleanup correctness.
- Write effects with proper cleanup so interrupted or concurrent renders don't cause resource leaks or race conditions.
