Live Streaming / Broadcast (Node.js, Redis, React, Docker, Socket.IO) overview

A live streaming and broadcast platform enabling real-time video distribution with interactive chat and viewer engagement features. Node.js handles stream ingestion, transcoding orchestration, and HLS manifest generation for adaptive bitrate delivery. Socket.IO powers the real-time chat, viewer polls, and donation overlays with sub-second latency. React renders the player interface with chat integration, stream quality selectors, and clip creation tools. Redis manages viewer presence, chat rate limiting, and stream metadata caching. Docker containers isolate transcoding workers for horizontal scaling during peak concurrent viewer loads. The tradeoff is transcoding infrastructure cost during high-concurrency events and ensuring chat consistency across geographically distributed viewers.
