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 🙏

Usage

// Import all custom actions
import { registerActionOptions } from "stimulus-fx";
registerActionOptions(application);

// Or only import specific custom actions
import { whenOutside } from "stimulus-fx/actions";
application.registerActionOption("whenOutside", whenOutside);

// Or like this
import { whenOutside } from "stimulus-fx/actions/whenOutside";
application.registerActionOption("whenOutside", whenOutside);

In your HTML:

<div data-controller="dropdown">
  <button data-action="dropdown#show:stop">Show</button>

  <ul data-dropdown-target="menu" data-action="click@window->dropdown#hide:whenOutside">
  </ul>
</div>

Available action options

  • throttled (use data-throttled-wait='2000' to specify the interval)
  • withConfirm
  • withKey (use data-key='meta' to specifiy the key, or data-key='ctrl,shift' for multiple keys)
  • withMetaKey; deprecated use withKey instead
  • whenOutside

Enhanced Stimulus debugging

Stimulus FX offers an experimental enhanced debugging feature that goes beyond Stimulus' standard debug = true option. Not only does it show the same details as the default debug option, but it also displays your controller's targets and values.

Preview of enhanced debugging with Stimulus

Here's how to set it up:

// app/javascript/controllers/application.js
+import { enableDebug } from "stimulus-fx"

-const application = Application.start()
+const application = enableDebug(Application.start())

You can enable debugging for specific controllers:

 export default class extends Controller {
+  static debug = true
+
}

For the best experience, it's recommended to turn off Stimulus' default debug feature when using this enhanced version.

Release

Because I always forget how to do this and don't feel like pulling a third-party dependency for releasing.

npm version patch # or minor, or major
npm publish
git push
git push --tags
