Common Fixes I Implement

Ensure Pre-rendered Meta

Dynamic meta tags must be generated on the server, not the client.

export const getServerSideProps = async () => { ... }

Fix Hydration Errors

Mismatched HTML between server and client kills performance and UX.

Error: Text content does not match server-rendered HTML.

Sitemap for Dynamic Routes

Automatically generate sitemaps for thousands of database-driven pages.

next-sitemap.config.js // generateRobotsTxt: true
