I want to launch a lean but fully working social network that feels familiar to Instagram users and is built entirely with React on the front-end, Node.js on the back-end and PostgreSQL as the data store. Core features I need from day one are: photo and video sharing (upload, display, feed), real-time direct messaging between users, and rich user profiles with avatar, bio and basic follow / unfollow mechanics. For authentication I only need a solid email-and-password flow right now, but the codebase should be organised so that OAuth providers can be slotted in later without a full rewrite. Please structure the project as a modern SPA: React (hooks, context or Redux if you prefer), responsive UI, lazy-loaded media, and clean routing. The server may use Express or a comparable Node fra...
