A solution to the IP Address Tracker challenge

Solution retrospective

In this challenge I created a small express app in order to hide the secret API_KEY from IP Geolocation API.

That's my first time using environment variables on Netlify, then I was not sure how to access these variables on development context. I ended up creating a .env file and used the dotenv library for development. It worked. But, I think it's better I do some more research about this topic. But if someone knows, I will be very glad to hear if I did the right thing.

    Hello Vander, congrats on finishing this challenge! pretty good job with the API_KEY hide on the backend!

    You App seems to work good but I can enter any type of value and it keeps loading to infinity, maybe you can add some validation to your input so it only gets valid ip's or domains, you can use a simple regular expression on your function that executes the code, for example this one:

    const ipRegex = '^((25[0-5]|(2[0-4]|1[0-9]|[1-9]|)[0-9])(\.(?!$)|$)){4}$'

    Also would recommend you to handle the error in the html or maybe displaying an alert() so a normal user can see when the app is failing and why, you can use a try catch block in your fetch function and catch the error, and the display the error if it fails, don't know how it works with axios tho, I have always used the fetch function.

    Hope my feedback helps you!, Good job!
