The siteSettings document is a singleton — there is exactly one per site. It controls global branding (logo, site name), header navigation, footer content, social links, and contact information.

​
Singleton pattern

The singleton is enforced in two ways:
  1. Document actions — sanity.config.ts restricts allowed actions to publish, discardChanges, and restore. Editors cannot create or delete the document.
  2. New document options — siteSettings is removed from the “New document” menu so a second instance cannot be created.
On the production dataset, the document ID is siteSettings. On the rwc dataset, each site has its own singleton: siteSettings-rwc-us and siteSettings-rwc-intl. getSiteSettingsId() in sanity.ts returns the correct ID for the current build.

​
Fields

​
Branding group

​
siteName
string
required
Full site name (e.g. YWCC Industry Capstone). Used in the <title> tag fallback and footer.
​
site
string
Multi-site discriminator. Hidden on the production dataset.
​
siteDescription
text
Default meta description for pages that do not have their own SEO description set.
Primary site logo. Used in the header. Supports hotspot. Must include alt text.

​
ctaButton

​
navigationItems
array of objects
Ordered list of header navigation links. Each item uses linkFields (label, href) and supports a children array for dropdown sub-items.
Sub-items (children) are stored in the schema but are not yet rendered in the header. Rendering dropdown navigation is planned for a future story.
​
footerContent
object
Footer body content with two sub-fields:
  • text (text) — body copy shown in the footer
  • copyrightText (string) — copyright line in the footer bottom bar
​
footerLinks
array of objects
Links shown in the footer bottom bar (e.g. Privacy Policy, Terms of Use). Each item uses linkFields.
​
resourceLinks

Links shown in the footer Resources column. Each item uses linkFields.
​
programLinks
array of objects
Links shown in the footer Programs column. Each item uses linkFields.

​

​
socialLinks
array of objects
Social media links. Each item has:
  • platform (string, required) — one of github, linkedin, twitter, instagram, youtube
  • url (url, required) — full URL to the profile
​
contactInfo
object
Contact information displayed in the footer. Sub-fields:
  • address (string)
  • email (string, validated as email with a warning)
  • phone (string)
​
currentSemester
string
Current academic semester label (e.g. Fall 2026). Displayed in various blocks and used as a default semester filter. Format: Season YYYY.

​
Fetching site settings

getSiteSettings() in sanity.ts fetches the singleton and caches the result for the entire build: 
export async function getSiteSettings() {
  if (!visualEditingEnabled && _siteSettingsCache) return _siteSettingsCache
  const { result } = await loadQuery({
    query: SITE_SETTINGS_QUERY,
    params: { siteSettingsId: getSiteSettingsId() },
  })
  _siteSettingsCache = result
  return result
}
It is called from Layout.astro, Header.astro, and Footer.astro. Because of the module-level cache, only one API call is made per build regardless of how many pages include those components.
