Hi, my name is Jonatan Heyman. I made this website in a few hours on a train, while commuting to Stockholm.
More than once I've needed the zip code/postal code for the place I’m currently at, and the swedish postal service’s website is pretty bad. This is my attempt to solve this problem.
Another project of mine is Hotels Near Me. It's a little similar to this website, but instead of showing you the postal code of your current location, it'll list all nearby hotels with available rooms. Check it out at hotels-near-me.today.
This website is built using Flask, Leaflet, and JavaScript Geolocation API. In the process of building this website I also created a small JavaScript library for throttling the browser's watchPosition() callbacks, which I've open sourced.
