hyperate ⏱

hyperate provides a wrapper around a http.RoundTripper to help rate limit outgoing HTTP requests.

Installation

go get github.com/dstotijn/hyperate

Usage

Simple

// Create an http.RoundTripper that rate limits outgoing HTTP requests to 10
// per second, allowing bursts of 5 requests.
rt := hyperate.New(http.DefaultTransport, rate.NewLimiter(10, 5))
client := &http.Client{Transport: rt}

Based on HTTP response headers

Use HTTP response headers (RateLimit-Remaining and RateLimit-Reset) (draft-polli-ratelimit-headers-02) to continously set rate limit.

rt := hyperate.New(http.DefaultTransport, rate.NewLimiter(rate.Inf, 1),
    hyperate.WithRateLimitHeaderCheck(),
)
client := &http.Client{Transport: rt}
