App Footer

Figma GitHub

A footer that appears on every screen to display supplementary information and links.

The App Footer is a universal component designed to provide essential links and content at the bottom of the application.

Usage

When to use

  • On every screen of an application where universal links or content are required.

Order of content

While the Ember component allows flexibility in the ordering of links and content, we recommend the following structure for a consistent visual appearance across applications:

  • StatusLink
  • LegalLinks
  • Additional links
  • Plain text items (or metadata, such as version numbers)
  • Copyright

Example of the recommended order of content within the App Footer

The StatusLink is used to communicate the application status via a third-party service or tool (such as statuspage.io). If needed, the status can be customized to suit the specific product needs.

Example of status link options

A set of standard legal links are provided by default. These are recommended for customer-facing products, but can be turned on/off within the component as needed.

Example of the App Footer with legal links only

Additional links can be added as necessary. Common examples may include linking to a changelog, GitHub, etc.

Example of the App Footer with additional links

Plain text items

Plain text content can be added after the links. This is often used for displaying the version number or other metadata related to the product.

Example of the App Footer with plain text list items

Extra content blocks

Extra content blocks are available before the list of links and before the copyright.

Example of where additional content can go in the App Footer

Do

The extra content block can be used to add quick interactions that change the whole application, e.g., a theme switcher.

Example of what additional content can go in the App Footer

Don’t

Avoid adding information that's critical to the user's journey in the App Footer.

Example of what additional content should not go in the App Footer

Themes

The App Footer supports both Light and Dark theme options. The dark theme can be used when there is a need for a footer on a dark background, e.g., a loading screen, but it should be used sparingly.

Responsiveness

In Figma, we support two size variants, Large and Small, to help illustrate how the component will respond to different viewport sizes. In code, the component is responsive.

Due to limitations in Figma, the component may not be a direct translation to what is rendered in the browser. The Ember component should be the source of truth for proper wrapping.

Large

The Large size accounts for most larger viewport sizes and, depending on the number of links and additional content, will display elements in a single row or wrap as the viewport size is reduced.

Please note, this screenshot is reduced in size to fit within the content container of the website.

How to use this component

The AppFooter is used to display a brief list of useful links and information relevant to an entire application.

Basic invocation with recommended content

The AppFooter contains only a copyright by default. The provided LegalLinks child component is recommended for inclusion in application footers for our cloud products such as HCP and TFC.

© 2024 HashiCorp 
<Hds::AppFooter as |AF|>
  <AF.LegalLinks />
</Hds::AppFooter>

Add the StatusLink to display information on the health of your application. Pass a predefined status name or use individual arguments to set text, statusIcon, iconColor to create a custom status type. Pass a custom href value to point to a custom URL.

© 2024 HashiCorp 
<Hds::AppFooter as |AF|>
  <AF.StatusLink @status="operational" />
</Hds::AppFooter>

You can add custom links in addition to or instead of including LegalLinks.

  <AF.Link
    @href="https://cloud.hashicorp.com/docs/changelog"

</Hds::AppFooter>

Item

Item components can be used to include meta text or other non-link content.

  • v.2.0
  • Vault
  • API: 1.0

  • 1.4.10 Reflow (Level AA):
    Content can be presented without loss of information or functionality, and without requiring scrolling in two dimensions.
  • 1.4.3 Minimum Contrast (Level AA):
    The visual presentation of text and images of text has a contrast ratio of at least 4.5:1
