Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

reqlimit

A utility to limit the number of requests per second.

See the examples directory for some usages.

API

Constructor reqlimit(maxRps:number):reqlimit

maxRps is the highest number of requests/second that you want reqlimit to allow.

reqlimit.check(key:object):object

Where key is any suitable identifer for a recurring request. This function calculates requests per second, and marks an entry as "blocked" if the calculation exceeds maxRps. If an entry is blocked, this function stops its calculations.

The returned object contains the following properties:

	count	// The number of requests made by this entry
	last	// A timestamp of the last request made (in milliseconds since epoch)
	rps		// Current request/second
	block	// Boolean indicating if the entry exceeded maxRps

reqlimit.release(timeout:number)

Removes entries that are older than timeout (in seconds).
