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.


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 🙏

Small timing library




nanotiming stability

npm version build status downloads js-standard-style

Small timing library. Useful to integrate into libraries that have multiple methods. Works both in the browser and Node. To use this in Node, make sure you are using v8.5.0 or greater.


var nanotiming = require('nanotiming')
// require 'perf_hooks' for Node environment
// var performance = require('perf_hooks').performance

var timing = nanotiming('my-loop') // Start profiling

var i = 1000
while (--i) console.log(i)

// Stop profiling

// in the browser
var timings = window.performance.getEntries()
var timing = timings[timings.length - 1]
console.log(, timing.duration) // log the last entry
window.performance.clearMeasures(    // be a good citizen and free after use

// in Node 
var timings = performance.getEntries()
var timing = timings[timings.length - 1]
console.log(, timing.duration) // log the last entry
performance.clearMeasures(    // be a good citizen and free after use

Timing names

Timings inside the view are appended with a unique UUID so they can be cleared individually. While there's no strict format for timing formats, we recommend using a format along these lines:

choo.render [12356778]
choo.route('/') [13355671]
choo.emit('log:debug') [13355675]

Disabling timings

Performance timers are still a somewhat experimental technology. While they're a great idea conceptually, there might be bugs. To disable timings complete, in the browser set:

window.localStorage.DISABLE_NANOTIMING = true

Alternatively, in Node set:

process.env.DISABLE_NANOTIMING = true


endTiming = nanotiming(name)

Start a new timing.


The unique ID created for the timing.

endTiming([cb(err, name)])

Close the timing. Measuring the timing is done inside a requestIdleCallback() (browser) or setTimeout (node) tick, so it might not be available immediately. If a callback is passed it will be called with an error (if measuring wasn't successful) and the timing's name.
