We would like for you to build out an API exposing an endpoint that returns the geolocation info for an IP v4 address received as a param.

Backend

Please implement the backend in Node.js (any framework or no framework at all — your choice).

Your API should expose a single GET endpoint that receives an IPv4 address and returns its location data in JSON.

You may use this CSV file that contains partial location

Using SSHFS to mount your Raspberry Pi's home directory on your Mac

It is useful to be able to mount your Raspberry Pi's file system on your Mac's desktop. The Raspberry Pi is ready to rock-'n-roll but some work needs to be done on the Mac. This gist assumes macOS Mojave 10.14. Your mileage may vary on earlier or later versions.

Set up passwordless SSH (optional)

You can make your life quite a bit simpler if you set up SSH on your Mac so that it can login to your Raspberry Pi without needing a password. Follow this tutorial.

The tutorial assumes two Raspberry Pis but there is no difference in approach if you use a Mac and a Pi, or two Macs.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• A Russian translation of this article can be found here, contributed by Timur Demin.
• A Turkish translation can be found here, contributed by agyild.
• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
