Rate limit API requests in Sanic and append remaining number to response

Question

I am trying to implement rate limiting for requests in Sanic. Unfortunately, the sanic-limiter package on PyPI has not been maintained for years and is not working with current Sanic versions.

I found some GitHub fork of that package, which can be used to set a global request limit by defining a limiter:

limiter = Limiter(
        app,
        global_limits = [
            "1 per second",
            "500 per day"
            ],
        key_func = get_remote_address
    )

I couldn't get other parts of the exampes working; thus, I assume that version of sanic-limiter is also not fully compatible with current Sanic versions. According to the description, sanic-limiter is supposed to be the Sanic version of Flask-Limiter, which is linked in the references of the repo.

Flask-Limiter provided the functionality I am interested in, as described in the docs:

@app.after_request
def add_headers(response):
    if limiter.current_limit:
        response.headers["RemainingLimit"] = limiter.current_limit.remaining
        response.headers["ResetAt"] = limiter.current_limit.reset_at
        response.headers["MaxRequests"] = limiter.current_limit.limit.amount
        response.headers["WindowSize"] = limiter.current_limit.limit.get_expiry()
        response.headers["Breached"] = limiter.current_limit.breached
    return response

I tried to translate this into Sanic like this:

    @app.middleware("response")
    async def add_headers(request, response):
        if limiter.current_limit:
            response.headers["RemainingIDs"] = str(
                limiter.current_limit.remaining
                )
            
            response.headers["ResetAt"] = str(
                limiter.current_limit.reset_at
                )
        
        return response

but the limiter apparently does not have those attributes.

Now, I wondered whether anybody got some rate limit working on a current Sanic version and knows how to return the number of remaining requests. Unfortunately, sanic-limiter is barely documented and probably does not provide all required functionalities. So, maybe you know an alternative to sanic-limiter or some work-around?
