Real-Time Data Streaming with Node.js and RxJS

In today's fast-paced digital landscape, processing live data as it happens is a crucial skill for modern web developers. This text-based course guides you through the process of connecting to real-time public data streams, handling continuous event flows, and filtering information based on location and keywords. You will transform raw, high-velocity data into structured, actionable insights using reactive programming principles. By completing this course, you will understand how to build resilient streaming pipelines that can ingest, filter, and process live event feeds. What you'll learn: Understand the core concepts of event-driven architectures and reactive programming; Configure a secure Node.js environment to connect to external streaming APIs; Apply RxJS operators to filter, map, and throttle incoming real-time data packets; Implement geographic bounding boxes to isolate stream data by specific map coordinates; Manage stream backpressure and handle connection dropouts gracefully; Structure modern asynchronous Node.js code using clean event-handling patterns. You will start with the absolute fundamentals of stream-based architectures and API authentication, then progress step-by-step through setting up RxJS observables to handle continuous data flows. This course is designed specifically for beginners with basic JavaScript knowledge who want to explore real-time backend development without any complex prerequisites.
