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 🙏

<paper-listbox>

<paper-listbox> implements an accessible listbox control with Material Design styling. The focused item is highlighted, and the selected item has bolded text.

<paper-listbox>
  <paper-item>Item 1</paper-item>
  <paper-item>Item 2</paper-item>
</paper-listbox>

An initial selection can be specified with the selected attribute.

<paper-listbox selected="0">
  <paper-item>Item 1</paper-item>
  <paper-item>Item 2</paper-item>
</paper-listbox>

Make a multi-select listbox with the multi attribute. Items in a multi-select listbox can be deselected, and multiple item can be selected.

<paper-listbox multi>
  <paper-item>Item 1</paper-item>
  <paper-item>Item 2</paper-item>
</paper-listbox>

Styling

The following custom properties and mixins are available for styling:

| Custom property | Description | Default | | --- | --- | --- | | --paper-listbox-background-color | Menu background color | --primary-background-color | | --paper-listbox-color | Menu foreground color | --primary-text-color | | --paper-listbox | Mixin applied to the listbox | {} |

Accessibility

<paper-listbox> has role="listbox" by default. A multi-select listbox will also have aria-multiselectable set. It implements key bindings to navigate through the listbox with the up and down arrow keys, esc to exit the listbox, and enter to activate a listbox item. Typing the first letter of a listbox item will also focus it.

See: Documentation, Demo.
