@hiqsociety Yes there is a middleware for fasthttp, you can find an example here: https://github.com/ulule/limiter-examples/blob/master/fasthttp/main.go

@gitmko0 Yes you can, but you'll have to create some plumbing and boilerplate to do so.

In summary, create a new instance of limiter with the new rate (https://github.com/ulule/limiter/blob/545607961466ac04a70680947ce0f0e7fbb2366f/limiter.go#L31)

And pass this new instance to the service / middleware / components managing the rate limiter, by replacing the previous instance and this new one.
