The text details a project that uses Open Notify's API and PubNub to track and display the location of the International Space Station (ISS) in real-time. The author begins by expressing their fondness for the IFTTT app, which inspired them to create a custom solution that sends notifications when the ISS is overhead. By utilizing Open Notify's simple API, the project retrieves ISS coordinates, processes them through a server-side script with npm packages 'get-json' and 'pubnub', and publishes the data through PubNub. On the client side, a basic HTML file using Mapbox and JavaScript displays the ISS location on a map, updating in real-time as new data is received. The project serves as a demonstration of streaming dynamic data from a source and publishing it elsewhere, with potential applications in tracking real-time stock market data.
