Prompt engineering a CMS schema

1. current redundancy issues:
   • multiple gallery implementations (media, recordings, events)
   • repeated presentation patterns (hero sections, sliders)
   • duplicated filtering/sorting logic
   • similar display options across different content types
2. Sitecore’s “content item” approach: the Sitecore model you referenced is powerful because it:
   • treats everything as a “content item”
   • separates items into:
     • pure data items (recordings, events)
     • presentation items (galleries, sliders)
     • hybrid items (smart galleries that know how to query)
3. potential solutions in Sanity: while Sanity doesn’t have Sitecore’s exact capabilities, we could try either of the following approaches to defining a gallery:
   • a reference-based approach: (…code sample here…)
   • a GROQ-based approach:

       {
         name: 'dynamicGallery',
         fields: [{
           name:'groqQuery',
           type:'string',
           description:'GROQ query to fetch items'
       }]
       }
     

Instead, we could think about this in terms of “smart components” that have predefined, user-friendly filtering options. For example:

// A more user-friendly approach
{  name:'recordingGallery',  fields:[{      name:'contentSource',      type:'string',      options:{        list:[{title:'Latest Releases', value:'latest'},{title:'Featured Albums', value:'featured'},{title:'By Genre', value:'genre'},{title:'By Year', value:'year'},{title:'Manual Selection', value:'manual'}]}},
// If they choose 'genre'
{      name:'genres',      type:'array',of:[{type:'string'}],      options:{        list:['Classical','Jazz','Contemporary']},hidden:({parent})=> parent?.contentSource !=='genre'},
// If they choose 'year'
{      name:'yearRange',      type:'object',      fields:[{name:'from', type:'number'},{name:'to', type:'number'}],hidden:({parent})=> parent?.contentSource !=='year'},
// If they choose 'manual'
{      name:'selectedRecordings',      type:'array',of:[{type:'reference', to:[{type:'recording'}]}],hidden:({parent})=> parent?.contentSource !=='manual'}]}

This approach:

1. Presents clear, meaningful choices to the content author
2. Hides complexity behind simple selections
3. Still maintains the flexibility of different content sources

4. Keeps the UI intuitive and purpose-driven We could reduce redundancy by:

5. Creating base display components (grid, carousel, etc.)
6. Creating smart content selectors for each content type
7. Combining them in ways that make sense for the content type

For example, a recording gallery and a media gallery might share the same grid display component, but have different content selection interfaces that make sense for their respective content types.

This maintains the power of dynamic querying while keeping the interface accessible to non-technical users. What do you think about this direction?

Here’s a potential approach using Sanity’s API customization:

1. define base presentation interfaces:

    // Base gallery interface
    interface GalleryBase {
      displayStyle: 'grid' | 'carousel' | 'list';
      columns?: number;
      spacing?: 'compact' | 'normal' | 'spacious';
      aspectRatio?: '1:1' | '16:9' | '4:3';
    }
    // Base gallery item interface
    interface GalleryItemBase {
      title: string;
      subtitle?: string;
      thumbnail: ImageAsset;
      link?: string;
      metadata?: Record<string, any>;
    }
   

2. create content-specific mappers:

    // In your Sanity schema
    export default {
      name: 'recordingGallery',
      type: 'document',
      fields: [
        // ... your user-friendly selection fields
      ],
      // This is where the magic happens
      preview: {
        select: {
          contentSource: 'contentSource',
          genres: 'genres',
          yearRange: 'yearRange',
          selectedRecordings: 'selectedRecordings'
        },
        prepare(selection) {
          return {
            ...selection,
            // Define how this should be serialized
            __galleryConfig: {
              mapToGalleryItem: 'recording', // Tell Sanity this needs recording->gallery mapping
              displayConfig: {
                // Default display settings for recordings
                aspectRatio: '1:1',
                metadata: ['year', 'genre', 'duration']
              }
            }
          }
        }
      }
    }
   

3. create a Sanity plugin for content mapping:

   // sanity-plugin-content-mappings.ts
   import createPlugin from 'sanity-plugin-content-mappings'
   export default createPlugin({
     name: 'content-mappings',
     contentMappers: {
       recording: {
         toGalleryItem: (recording) => ({
           title: recording.title,
           subtitle: recording.artist,
           thumbnail: recording.coverArt,
           link: `/recordings/${recording.slug.current}`,
           metadata: {
             year: recording.releaseDate?.split('-')[0],
             genre: recording.genre,
             duration: recording.duration
           }
         })
       },
       performance: {
         toGalleryItem: (performance) => ({
           title: performance.title,
           subtitle: performance.venue,
           thumbnail: performance.image,
           link: `/performances/${performance.slug.current}`,
           metadata: {
             date: performance.date,
             location: performance.location
           }
         })
       }
       // Add more mappers as needed
     }
   })
   

4. create a custom “client wrapper:”

   // sanityClient.ts
   import { createClient } from '@sanity/client'
   const client = createClient({
     // ... your config
   })
   // Add automatic content mapping
   export const enhancedClient = {
     fetch: async (query, params) => {
       const result = await client.fetch(query, params)
       // If the result contains gallery configuration
       if (result.__galleryConfig) {
         return transformToGallery(result)
       }
       return result
     }
   }
   function transformToGallery(data) {
     // Apply the appropriate content mapper
     const mapper = contentMappers[data.__galleryConfig.mapToGalleryItem]
     return {
       // Gallery base properties
       displayStyle: data.displayStyle || 'grid',
       columns: data.columns || 3,
       spacing: data.spacing || 'normal',
       // Transform items using the mapper
       items: data.items.map(item => mapper.toGalleryItem(item))
     }
   }
   

5. use in your frontend:

    // Your frontend component
    const GalleryComponent = () => {
      const gallery = useQuery('*[_type == "recordingGallery"]')
      // gallery data is already transformed to:
      // {
      //   displayStyle: 'grid',
      //   columns: 3,
      //   items: [
      //     {
      //       title: "Album Name",
      //       subtitle: "Artist",
      //       thumbnail: {...},
      //       link: "/recordings/album-slug",
      //       metadata: {
      //         year: "2024",
      //         genre: "Classical",
      //         duration: "1:23:45"
      //       }
      //     },
      //     // ... more items
      //   ]
      // }
      return <GenericGallery {...gallery} />
    }
   

This approach gives you:

1. clean separation between content and presentation
2. automatic transformation of content types to presentation types
3. consistent gallery structure across different content sources
4. type-safe interfaces for your frontend
5. centralized mapping logic
6. user-friendly CMS interface

1. content authors get:
   • Simple, purpose-built interfaces
   • No exposure to technical details
   • Natural workflows (“I want a gallery of my latest recordings”)
2. frontend developers get:
   • Consistent data structures
   • Type-safe interfaces
   • One set of presentation components
   • No query spaghetti
3. backend developers get:
   • Centralized transformation logic
   • Clear separation of concerns
   • Extensible mapping system
   • Clean schema definitions

We could extend this pattern to other common presentation needs:

interface HeroBase {
  layout: 'full' | 'split' | 'overlay';
  content: {
    title: string;
    subtitle?: string;
    description?: string;
    cta?: ButtonConfig;
  };
  media: ImageAsset | VideoAsset;
}

And then to corresponding mappers like:

performance: {
  toHero: (performance) => ({
    layout: 'overlay',
    content: {
      title: performance.title,
      subtitle: `${performance.venue} - ${formatDate(performance.date)}`,
      description: performance.description,
      cta: {
        label: 'Get Tickets',
        link: performance.ticketLink
      }
    },
    media: performance.featuredImage
  })
}

This schema design provides a comprehensive structure for a musician’s website, combining business domain entities with flexible presentation components.

The relationships are designed to be both logical and practical, allowing for complex content management while maintaining ease of use.

Now we’ve properly distinguished between the WebsiteOwner (the primary musician who owns the website) and other Artists who might appear in performances, recordings, and credits. Key changes include:

1. WebsiteOwner entity:
   • Central entity for the website owner
   • Has personal content (biography, education, skills)
   • Offers services and packages
   • Participates in performances and recordings
2. Artist entity:
   • Represents collaborators and other musicians
   • Referenced in performances, recordings, and credits
   • Has basic profile information
   • Many-to-many relationships with performances and recordings
3. updated relationships:
   • Performances can feature multiple artists
   • Recordings can feature multiple artists
   • Tracks can feature multiple artists
   • Credits explicitly reference artists
4. content ownership:
   • Biography, Education, and Skills are now explicitly tied to WebsiteOwner
   • Services are offered by the WebsiteOwner
   • Other artists are linked through performances, recordings, and credits

While we’ve set up preview configurations that help with the Studio experience, we haven’t yet implemented the transformations that would automatically convert specific content types (like recordings) into generic presentation structures (like gallery items) at the schema/API level.

Let me create these transformations.

I’ll start by creating a new directory for our transformations and implement the gallery transformation system.

I’ll continue by creating transformations for performances and artists into gallery items, as these are also common use cases for gallery presentations.

Now, let’s create a central index file to export all our transformations and register them in our schema: Now we have a complete transformation system that will:

1. Automatically transform specific content types (recordings, performances, artists) into standardized gallery items
2. Maintain consistent gallery structures across different content types
3. Handle all the complex GROQ queries at the schema level

For example, to create a gallery of recordings in your frontend, you would:

1. Create a recordingGallery document in Sanity Studio
2. Add references to the recordings you want to display
3. Configure the gallery layout and filters

Then in your frontend, you can simply query the gallery and all the transformations will be handled automatically.

The data will come pre-structured in a consistent gallery format, regardless of whether it’s displaying recordings, performances, or artists.

For example, a simple GROQ query might look like:

*[_type == "recordingGallery" && _id == $galleryId]{
  title,
  description,
  layout,
  "items": items[]{
    title,
    subtitle,
    description,
    "image": image.asset->url,
    tags,
    link,
    metadata
  }
}

This will give you a fully structured gallery with all the recording data already transformed into the appropriate format.

No complex joins or transformations needed in the frontend code.

Would you like me to add more transformations for other content types, or would you like to start working on the frontend implementation now?

I’ve set up the initial frontend implementation with Next.js, TypeScript, and Tailwind CSS. The frontend now includes:

1. a reusable Gallery component system that can display any of our transformed gallery types (recordings, performances, artists)
2. responsive layouts with grid, masonry, carousel, and list options
3. filtering capabilities based on tags
4. smooth animations and transitions using Framer Motion
5. image optimization using Next.js Image component
6. type-safe code with TypeScript

To complete the setup, you’ll need to create a .env.local file in the src/frontendtake01 directory with the following environment variables:

NEXT_PUBLIC_SANITY_PROJECT_ID=your_project_id
NEXT_PUBLIC_SANITY_DATASET=production`

To run the frontend:

1. navigate to the frontend directory: cd src/frontendtake01
2. install dependencies: npm install
3. start the development server: npm run dev

The frontend will automatically fetch and display any galleries you create in your Sanity Studio.

Each gallery will be properly transformed and displayed according to its layout settings.

Currently, the Gallery component supports four basic layout options:

1. grid - A traditional grid layout where items are arranged in equal-sized cells
2. masonry - A Pinterest-style layout where items maintain their aspect ratios and are arranged in columns
3. carousel - A horizontal scrolling layout where items can be swiped/scrolled through
4. list - A vertical list layout where items are stacked

We could enhance these layouts with additional options like:

1. Advanced Grid Options:
   • Varying item sizes (some items spanning multiple cells)
   • Dynamic columns based on screen size
   • Different aspect ratios for different content types
2. Advanced Masonry Options:
   • Custom column widths
   • Priority placement for featured items
   • Animated item insertion/removal
3. Advanced Carousel Options:
   • Multiple items per slide
   • Auto-play functionality
   • Different transition effects
   • Infinite scroll
4. Advanced List Options:
   • Alternating item alignments
   • Timeline-style layout
   • Compact vs. expanded views
5. New Layout Types:
   • mosaic - A more artistic grid with predefined patterns
   • staggered - Items arranged in an offset pattern
   • horizontal - Side-scrolling with variable item widths
   • showcase - Featured items with spotlight effects
6. Enhanced Filtering:
   • Multiple simultaneous filters
   • Search functionality
   • Sort options (date, alphabetical, etc.)
   • Filter animations

1. Card Transforms
   • PersonCard - For artists, collaborators, team members
   • EventCard - For performances, workshops, masterclasses
   • ProductCard - For merchandise, courses, packages
2. List Transforms
   • Timeline - For event histories, career milestones
   • Schedule - For upcoming performances, lessons
   • Playlist - For tracks, recordings, videos
   • PriceList - For services, packages, merchandise
3. Hero Transforms
   • PageHero - For main page headers
   • EventHero - For featured performances
   • ProfileHero - For artist profiles
   • AlbumHero - For featured recordings
4. Grid Transforms
   • ServiceGrid - For service offerings
   • TestimonialGrid - For client feedback
   • SkillGrid - For capabilities and expertise
   • AchievementGrid - For awards and recognition
5. Detail Transforms
   • EventDetails - Complete performance information
   • ArtistBio - Structured biography presentation
   • AlbumDetails - Complete recording information
   • VenueDetails - Venue information and amenities
6. Feed Transforms
   • NewsFeed - For blog posts, updates
   • MediaFeed - For photos, videos
   • ReviewFeed - For performance reviews
   • SocialFeed - For social media integration
7. Stats Transforms
   • PerformanceStats - Venue counts, audience sizes
   • CareerStats - Years active, performances given
   • EngagementStats - Student counts, workshop attendees
   • MediaStats - Recording counts, streaming numbers
8. Calendar Transforms
   • EventCalendar - For performances
   • AvailabilityCalendar - For bookings
   • TourCalendar - For tour dates
   • ClassCalendar - For teaching schedules
9. Contact Transforms
   • BookingForm - For performance inquiries
   • LessonInquiry - For teaching requests
   • ContactDetails - For various contact methods
   • LocationInfo - For venue and teaching locations
10. Feature Transforms - ServiceFeatures - Highlight service benefits - ProgramFeatures - Highlight program contents - VenueFeatures - Highlight venue amenities - PackageFeatures - Highlight package inclusions

Each of these transforms would standardize the presentation structure while maintaining the specific business context, making your frontend development much more straightforward and consistent.

1. Stories File: Gallery.stories.tsx defines different variations of the component:
   • Different layouts (grid, masonry, list, carousel)
   • With/without filters
   • With/without title and description
2. Component Structure: Components are more isolated and don’t depend on Sanity
   • Removed Sanity-specific image handling
   • Simplified props interface
   • Mock data for demonstration
3. Documentation: The stories file includes:
   • Component documentation
   • Props documentation
   • Interactive controls
   • Visual examples

To run Storybook:

cd src/designcomponents
npminstallnpm run storybook

This will open Storybook in your browser where you can:

• See all Gallery variations
• Interact with props in real-time
• View component documentation
• Test different layouts and configurations

   • Display real-world examples

These enhancements help developers and designers better understand how to use the component in different situations and ensure it works correctly across various scenarios.

…(created Gallery.test.stories.tsx)…

I’ve created test stories that verify four key aspects of the Gallery component:

1. FilteringTest
   • Tests that filters work correctly
   • Verifies item counts after each filter change
   • Checks that “All” filter resets properly
2. AccessibilityTest
   • Verifies proper heading structure
   • Checks tab navigation order
   • Ensures buttons have accessible labels
3. EmptyStateTest
   • Verifies component handles empty data gracefully
   • Checks that title still displays
   • Ensures no items are rendered
4. LoadingStateTest
   • Verifies image loading behavior
   • Checks for proper alt text
   • Tests placeholder handling

These tests run automatically in Storybook and provide visual feedback when something fails. They help ensure the component remains functional as you make changes.

Would you like me to explain how to run these tests or add more test scenarios?

While GalleryItem is a child component of Gallery, it’s still a reusable component that should be tested and documented independently.

Let me create those:

…(created GalleryItem.stories.tsx)…

…(created GalleryItem.test.stories.tsx)…

I’ve created separate stories and tests for GalleryItem. Here’s what each file contains:

GalleryItem.stories.tsx:

• Default view with all features
• No image variation
• Long text handling
• Minimal content
• Different layout variations

GalleryItem.test.stories.tsx:

1. InteractionTest
   • Tests hover states
   • Verifies overlay content
   • Checks link behavior
2. AccessibilityTest
   • Tests image alt text
   • Verifies link accessibility
   • Checks keyboard navigation
3. ContentFallbackTest
   • Tests minimal content rendering
   • Verifies optional elements
   • Checks fallback behavior
4. AnimationTest
   • Tests initial animation state
   • Verifies animation completion
   • Checks final state

This separation allows us to:

• Test GalleryItem in isolation
• Document its individual features
• Verify its behavior independently
• Make it easier to reuse in other contexts besides Gallery

This is a common pattern in component libraries where both parent and child components get their own documentation and tests.
