Core flow

• Once signed in, users land on a news-feed style timeline that pulls posts from friends as well as their own. User interaction requirements
• Users must be able to send and accept friend requests.
• Each post can be shared to the user’s own timeline; a simple “Share” action that duplicates the post while referencing the original author is enough. Content handling
• Allow image, video and plain text uploads. Store media on disk or an S3-compatible bucket, and keep file metadata in MongoDB/mysql.
Preferred stack details React (hooks, functional components) Redux Toolkit or Context API for state Node/Express API, Mysql
