Implementing IP Address Rate Limiting in Go!?
JOIN MY DISCORD / discord
In this video, I discuss a simple implementation of IP address caching in Golang. It covers read-write mutexes, the use of Go routines to clear up stale cache items, and how I implemented it in an endpoint on a little side project.
The IP cache is a nice and simple in-memory Go map, so it's nice and basic and shows a use-case of maps to anyone trying to get familiar with Go.
I implemented this as a package that can be reused, so do let me know if you'd like this available as a module, I'll put some more time into making it production ready then!
