This tutorial provides a detailed guide to implementing real-time location tracking on a live-updating map using the EON framework and the Mapbox API with JavaScript. It explains how to stream data from a connected user, display their location on a map, and update the marker as the user moves. The tutorial includes steps for setting up Mapbox with EON, using PubNub for data streaming, and customizing markers and map elements. It also discusses using unique PubNub API keys for enhanced security, configuring distributed systems to compile messages from multiple sources, and offers guidance on customizing maps via the Mapbox API and editor. Practical examples, such as tracking multiple devices and publishing messages from different sources, are provided to illustrate the functionality of the system.
