FastAPI & Next.js project: Flight Booking App With DevOps. Day 1 - 100 - Server-Sent Events (SSE) in FastAPI—Starting In-App Notifications ⚡ | Flight Booking Engine | Day 55

In Day 55, we introduce SSE in FastAPI and lay the foundation for real-time updates without WebSockets. This is the first stream focused on pushing live events from the backend to the frontend. No magic. No abstractions. Just understanding how SSE works and why it fits perfectly for notifications. 💡 In this live session: • Understand what Server-Sent Events (SSE) are • Compare SSE vs WebSockets (when to use each) • Implement a basic SSE endpoint in FastAPI • Stream events from the backend to the client • Prepare the system for in-app notifications This is the starting point for live booking updates, ticket uploads, and admin-triggered notifications. 📂 GitHub Repo: 👉 https://github.com/KNehe/aero_bound_ventures-public.git 📘 Full Playlist: 👉 https://www.youtube.com/playlist?list=PLdtwawCR2QjmdfhM-7SzDOVGop373bbgW 🔥 Subscribe for real FastAPI + Next.js systems — built live, explained clearly, production-focused. #FastAPI #ServerSentEvents #FlightBookingApp #FullStack #Backend
