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 🙏

Smol frontend router


var nanorouter = require('nanorouter')
var router = nanorouter({ default: '/404' })

router.on('/foo', function (params) {
  console.log('hit /foo')
router.on('/foo/:bar', function (params) {
  console.log('hit a route with params',
router.on('/foo#baz', function (params) {
  console.log('we do hash routes too!')
router.on('/foo/*', function (params) {
  console.log('and even wildcards', params.wildcard)



How is this different from sheet-router?

sheet-router does slightly more and has a different syntax. This router is lighter, faster and covers less concerns. They're pretty similar under the hood though.


router = nanorouter([opts])

Create a new router. opts can be:

  • opts.default: set a default handler in case no route matches. Defaults to /404

router.on(routename, handler(params))

Register a handler on a routename. The handler receives an object with params on each render. A result can be returned the caller function.

result = router.emit(routename)

Call a handler for a routename. If no handler matches, the handler specified in opts.default will be called. If no default handler matches, an error will be thrown. Results returned from the called handler will be returned from this function.

matchedRoute = router.match(route)

Matches a route and returns an object. The returned object contains the properties {cb, params, route}. This method does not invoke the callback of a route. If no route matches, the route specified in opts.default will be returned. If no default route matches, an error will be thrown.

Note that router() does not affect browser history. If you would like to add or modify history entries when you change routes, you should use history.pushState() and history.replaceState() alongside router().
