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 🙏

vcf-nav

Vaadin Component Factory component for navigation menus. This component is a stepping stone towards an official Vaadin component. Please provide feedback through issues in this repository.

Features

  • Navigation with a label can be collapsible
  • Navigation items can have prefix and suffix content, for example, icons and badges
  • Hierarchial items. A parent item can be without a path (non-navigable)
  • Supports keyboard and screen reader navigation

Missing features (things that will be added in the official component):

  • Material theme
  • Localization support (to provide a custom text for the expand/collapse button of a navigation item)
  • TypeScript types

Potential feature additions:

  • Horizontal variant (“navigation bar”), with sub-items in a popup
  • Icon-only variant (“navigation rail”), with sub-items in a popup
  • [insert your idea]

Usage

HTML

<vcf-nav collapsible>
  <span slot="label">Main menu</span>

  <vcf-nav-item path="/dashboard">
    <vaadin-icon icon="vaadin:chart" slot="prefix"></vaadin-icon>
    Dashboard
    <span theme="badge primary" slot="suffix" aria-label="(2 new items)">2</span>
  </vcf-nav-item>

  <vcf-nav-item>
    <vaadin-icon icon="vaadin:folder-open" slot="prefix"></vaadin-icon>
    Parent

    <vcf-nav-item path="/child1" slot="children">
      Child 1
    </vcf-nav-item>

    <vcf-nav-item path="/child2" slot="children">
      Child 2
    </vcf-nav-item>
  </vcf-nav-item>
</vcf-nav>

Java

NOTE: The Java classes are not included in this repository. You can get them by downloading a starter project from start.vaadin.com.

AppNav nav = new AppNav("Main menu");
nav.setCollapsible(true);

AppNavItem dashboard = new AppNavItem("Dashboard", "/dashboard");
dashboard.setIcon(new Icon(VaadinIcon.CHART));
Span newItems = new Span("2");
newItems.getElement().setAttribute("aria-label", "(2 new items)");
newItems.getElement().getThemeList().add("badge primary");
newItems.getElement().setAttribute("slot", "suffix");
dashboard.getElement().appendChild(newItems.getElement());

AppNavItem parent = new AppNavItem("Parent");
parent.setIcon(new Icon(VaadinIcon.FOLDER_OPEN));

AppNavItem child1 = new AppNavItem("Child 1", "/child1");
AppNavItem child2 = new AppNavItem("Child 2", "/child2");

parent.addItem(child1, child2);
nav.addItem(dashboard, parent);

Styling

This component does not utilize the Vaadin ThemableMixin interface, and therefore does not allow you to easily inject styles into its shadow DOM.

The component is meant to be styled using standard CSS features. Regular “light DOM” styling works for most things, and the ::part() selector for more detailed styling.

Example:

frontend/themes/[mytheme]/styles.css

html {
  --vcf-nav-child-indent: var(--lumo-space-m);
}

vcf-nav {
  padding: 0;
  font-size: var(--lumo-font-size-m);
  color: var(--lumo-body-text-color);
}

vcf-nav::part(label) {
  text-transform: uppercase;
  font-size: var(--lumo-font-size-xs);
}

vcf-nav-item::part(item) {
  border-inline-start: 2px solid transparent;
}

vcf-nav-item[active]::part(item) {
  border-inline-start-color: var(--lumo-primary-color);
}

<vcf-nav>

Parts

::part(label)
The <summary> element that displays the label of the navigation menu.

::part(label)::after
The expand/collapse icon of the label element. Defaults to var(--lumo-icons-dropdown).

State attributes

[collapsible]
Indicates that the navigation menu is user-collapsible and the pseudo element for the expand/collapse icon is visible.

[collapsed]
Indicates that the navigation menu has been collapsed and the navigation items are hidden.

<vcf-nav-item>

NOTE: the navigation item applies styles to any prefix element with a class name that contains "icon", assuming all such elements are meant to be the item icon.

Parts

::part(item)
The <a> element that contains the item label and prefix and suffix content.

::part(toggle-button)
The <button> element which contains the expand/collapse icon, if the item has child items.

::part(toggle-button)::before
The expand/collapse icon. Defaults to var(--lumo-icons-dropdown).

::part(children)
The <slot> element that contains any child items. Can be styled visually.

State attributes

[active]
Indicates that the item is currently the active/visible view in the application. This attribute is automatically set based on the current path/URL.

[child-active]
Indicates that a child item of this navigation item is currently active.

[expanded]
Indicates that the child items of this navigation item are visible.

Custom properties

--vcf-nav-child-indent
The amount of visual indentation of child items. Can be set globally in the html element. Defaults to var(--lumo-space-l).
