Munia is a full-stack social media web application built with Next.js 14, React 18, and TypeScript. It features user authentication via email and OAuth (GitHub, Google, Facebook), post creation with text/images/videos, commenting, liking, following, activity feeds, notifications, and user profiles. The architecture uses Next.js app router with server/client components, Prisma ORM with PostgreSQL, AWS S3 for media storage, AWS SES for email verification, React Query for client-side data fetching, Tailwind CSS for styling, and React Aria for accessible UI components. Key entry points include Next.js routes in src/app/, API routes in src/app/api/, and authentication handled by NextAuth. Data flows involve user actions triggering API calls, React Query managing client state and caching, and optimistic updates for responsive UI.
