ember-breadcrumb-trail is a minimalistic but very flexible breadcrumb management solution. It provides only 2 helpers but they give you complete control over the HTML structure, the components you use to render that structure and the needed data to make it all work. Bring your own everything!

This addon is heavily inspired by ember-page-title and the already existing breadcrumb addons.

• Ember.js v3.16 or above (lower versions might work, but aren't tested)
• Ember CLI v3.16 or above
• Node.js v12 or above
• Works with Embroider (safe and optimized) and FastBoot

ember install ember-breadcrumb-trail

This helper allows you to add breadcrumbs and is the equivalent of the page-title helper but for breadcrumbs.

Positional arguments are used as the title for the breadcrumb. Multiple positional arguments will be combined into a single title.

{{breadcrumb "Home"}}
{{! "Home" }}

{{breadcrumb "Hottest JS framework 🔥: " this.hottestFramework}}
{{! "Hottest JS framework 🔥: Ember" }}

The title can be accessed with the title property of the breadcrumb object.

Any data that you need to render your breadcrumbs can be passed in as named arguments. This can be used to pass route information so that the breadcrumb can be linked to it.

The named arguments will be available under the data property of the breadcrumb object.

This helper simply returns the registered breadcrumbs and can be used wherever you want to display them. The breadcrumb data can easily be looped over with {{#each}} and combined with other helpers if extra data manipulation is needed.

Array of registered breadcrumbs (objects)

This simple example implements an a11y friendly breadcrumb structure using Ember's <LinkTo> component and the {{has-next}} helper from ember-composable-helpers to determine if a breadcrumb is the last breadcrumb in the list.

<nav aria-label="Breadcrumb">
  <ol>
    {{#each (breadcrumbs) as |breadcrumb|}}
      <li>
        <LinkTo
          @route={{breadcrumb.data.route}}
          aria-current={{if (not (has-next breadcrumb breadcrumbs)) "page"}}
        >
          {{breadcrumb.title}}
        </LinkTo>
      </li>
    {{/each}}
  </ol>
</nav>

{{! index.hbs }}
{{breadcrumb "Home" route="index"}}

{{! about.hbs }}
{{breadcrumb "About" route="about"}}

A similar example where ember-link is used instead of <LinkTo>.

<nav aria-label="Breadcrumb">
  <ol>
    {{#each (breadcrumbs) as |breadcrumb|}}
      <li>
        <a
          href={{breadcrumb.data.link.href}}
          aria-current={{if (not (has-next breadcrumb breadcrumbs)) "page"}}
          {{on "click" breadcrumb.data.link.transitionTo}}
        >
          {{breadcrumb.title}}
        </a>
      </li>
    {{/each}}
  </ol>
</nav>

{{! blog.hbs }}
{{breadcrumb "Blog" link=(link "blog")}}

{{! blog/post.hbs }}
{{breadcrumb this.post.title link=(link "blog.post" this.post.id)}}
