I have used IP Chicken for checking my public IP Address for pretty much 15 years (since hearing about it on TechTV). Once upon a time, I tried writing my own alternative in ColdFusion but it is a lot of overhead for such a dumb thing. I started wondering if I could do it with just JavaScript.

This is one way? :)

It uses a service that CloudFlare offers, Vue.js, and Axios. The data that CloudFlare returns isn’t JSON but you can do some substrings to get what you need.

I will likely return to this at some point. I think that there is a better method.

Also, I created ip.jws.app (because why not?) if you want to see these concepts in action.
