The System
It's pretty simple. At sunrise and sunset, an iOS Shortcut sends my iPhone's approximate current location to the /api/location route in a POST request. The server then stores the data in a database and serves it to visitors.
This gives you a rough snapshot of where I am in the world, not a live GPS feed, plus the current local time. It's useful for friends and family, and honestly just a fun project.
If you're interested in how this works technically, you can find the complete source of this entire website on GitHub. The shortcut file can be downloaded here.
