Build My First Community Platform

Help me build my first community platform as a beginner using Next.js, TypeScript and Tailwind CSS with a real database. Explain the product model before coding.

Include registration, profiles, posts, comments, likes, follows, notifications, search, saved posts, reporting and moderation. Enforce authorization so users can only modify their own content unless they have an explicit moderator role. Add validation, pagination, abuse prevention, privacy-aware profiles, audit-friendly moderation states, loading/error/empty states, responsive accessible UI, SEO and deployment instructions. Use Next.js with TypeScript and Tailwind CSS. Build a polished, accessible, responsive application with clear beginner explanations, reusable components, semantic HTML, loading/error/empty states, form validation, SEO metadata, dark/light mode and deployment instructions. Explain important decisions as you go.
