Frontend Mentor - IP address tracker solution
This is my solution to the IP address tracker challenge on Frontend Mentor. Frontend Mentor challenges help you improve your coding skills by building realistic projects.
Built with HTML, CSS, Leaflet.js, and Express.js server for proxy and rate limit of https://geo.ipify.org API
If the map does not load it is because API is rate limited by the Express Proxy to 5 requests per 15 minutes so that limited API credits aren’t used up too quickly.
Overview
The challenge
Users should be able to:
- View the optimal layout for each page depending on their device’s screen size
- See hover states for all interactive elements on the page
- See their own IP address on the map on the initial page load
- Search for any IP addresses or domains and see the key information and location
My process
Built with
- Semantic HTML5 markup
- CSS custom properties
- Flexbox
- Express - Node.js Server framework api proxy
- Leaflet Maps
- Geo-ipify location API
What I learned
Use Typescript when building Express servers. Not having access to any method return types for http-proxy-middleware made route string conversion much more complicated than it needed to be.
