Virtual Yard: Terminal-Style Yard Management System Prompt (Svelte 5 / Svelte Flow)

Overview

Create a Svelte 5-based (Client Side Rendered ONLY) Yard Management System called "Virtual Yard" that visualizes warehouse parking spots and appointments in real-time. The application should match the LANEWEAVER TMS Bloomberg terminal aesthetic with a dark theme, monospace fonts, and high information density. The system should provide an interactive map of a warehouse facility showing loading docks, parking spots, and the current status of each space while maintaining the terminal-inspired design language.

Key Components

Header

• Terminal-style header with:
  • Application identifier in left corner ("4-LINEHAUL 2-VIRTUAL YARD")
  • Row of color-coded command buttons (QUOTE, NEW, TRACK, BOOK, DOCS, RATE, CARR)
  • System options in top right corner ("Tabs are here = Options")
• Status filter bar directly below header:
  • Main filters shown with triangular dropdown indicators
  • Checkbox-based subfilters with clear on/off states
  • Color-coded labels for different trailer types/statuses
• Secondary filter bar showing:
  • Current status
  • Item count
  • Sort criteria
  • Applied filter count
  • Last update timestamp

Warehouse Map

• Visual representation of the warehouse and yard layout
• Multiple sections of parking spots with clear labeling (R01-R29, P01-P69 in example)
• Color-coded spots reflecting their current status
• Interactive map allowing selection of spots
• Side section showing parking for trucks/trailers ("Gates" in example)

Appointment Sidebar

• "New Appointment" button at the top
• List of current appointments showing:
  • Transport company name
  • Truck license plate
  • Trailer license plate
  • Date (YYYY-MM-DD format)
  • Time (HH:MM format in 24-hour notation)
• Each appointment should be visually distinct (card-based UI)
• Ability to highlight the corresponding spot when an appointment is selected

Technical Requirements

1. Frontend
   • Create using Svelte 5 (Client Side Rendered ONLY) and TypeScript
   • Use a component-based architecture (leveraging Svelte's structure)
   • Implement responsive design principles
   • Use a modern UI library compatible with Svelte (e.g., Skeleton UI, Flowbite Svelte, or Tailwind directly)
   • Implement state management using Svelte's built-in stores (writable, readable, derived)
   • Integrate Svelte Flow library for drag-and-drop functionality
2. Map Visualization
   • Implement using Svelte Flow for interactive, draggable elements
   • Make each parking spot a "node" in Svelte Flow
   • Enable snap-to-grid functionality for all parking spots and docks
   • Make each trailer/truck a draggable element
   • Configure collision detection and space validation (if supported by Svelte Flow or implement custom logic)
   • Implement zoom and pan functionality
   • Allow for dynamic status updates
3. Data Management
   • Create models for:
     • Spaces (id, type, status, current_occupant, coordinates)
     • Appointments (company, vehicle_details, scheduled_time, assigned_space)
     • Facilities (name, layout_config)
     • Trailers (id, license_plate, company, status, current_position)
   • Implement CRUD operations for appointments and trailer positions
   • Ensure all spot labels (R01-R29, P01-P69, etc.) are programmatically generated and tied to backend data
   • Create a robust API integration to sync trailer positions with backend systems
   • Implement real-time database updates when trailers are moved
   • Add scheduling functionality that uses the actual yard layout data
   • Develop validation to prevent double-booking spaces
4. Additional Features
   • Search functionality
   • Filtering by status, time, company
   • Export/reporting capabilities
   • User roles and permissions
   • Dark/light mode toggle
   • Notifications for upcoming appointments

UI/UX Guidelines

1. Bloomberg Terminal-Inspired Design
   • Use a dark theme with high contrast elements (black background with bright text)
   • Match the LANEWEAVER TMS aesthetic exactly as shown in the example
   • Follow the terminal-style, information-dense approach
   • Implement a highly functional, data-first design philosophy
2. Color Scheme
   • Primary background: Black (#000000)
   • Secondary background: Dark gray (#1A1A1A) for alternating rows
   • Text: White (#FFFFFF) and yellow (#FFD700) for headers and highlights
   • Action buttons with distinct colors:
     • QUOTE: Red (#FF0000)
     • NEW: Green (#00FF00)
     • TRACK: Blue (#0000FF)
     • BOOK: Green (#00AA00)
     • DOCS: Teal (#008B8B)
     • RATE: Purple (#800080)
     • CARR: Orange (#FFA500)
   • Status colors:
     • Empty: Light blue (#ADD8E6)
     • Loading: Yellow (#FFD700)
     • Loaded: Green (#00FF00)
     • External: White striped pattern
   • Highlight positive values in green (#00FF00)
   • Highlight critical data in yellow (#FFD700)
   • Use blue (#0000FF) for clickable items or links
3. Typography
   • Use monospace fonts exclusively (Consolas, Monaco, or similar)
   • Keep all text uppercase for headers and labels
   • Use mixed case for data content
   • No rounded corners or fancy styling
   • Maintain high contrast ratios for readability
4. Layout
   • Dense, tabular data presentation
   • Fixed-width, terminal-style layout
   • Command buttons at the top
   • Status bars and filters directly below command area
   • Main content in a dense data grid/table
   • Detail panels at the bottom
   • Use dot leaders or color blocks for visual separation
   • Minimize white space, maximize information density
   • Use color to distinguish between different data types rather than spacing

Sample Data Structure

Provide sample JSON structures for:

1. Warehouse Layout Configuration:
2. Trailer Data:
3. Appointment Data:
4. Real-time Status Updates:

Implementation Approach

1. Begin with static UI components matching the design using Svelte components.
2. Integrate Svelte Flow and implement the interactive yard map
   • Set up draggable trailers/trucks as nodes or custom elements.
   • Create snappable parking spots and dock positions (nodes).
   • Configure proper coordinates and collision detection (may require custom logic).
3. Implement programmatic labeling system for all spaces
   • Ensure each label has a corresponding database entry.
   • Build validation logic for space assignment.
4. Set up state management with Svelte stores and proper backend integration
   • Create real-time sync for trailer positions (e.g., using WebSockets connected to stores).
   • Build API connectors for appointment data.
5. Develop the appointment management system
   • Link appointments directly to yard positions.
   • Implement scheduling logic that prevents conflicts.
6. Add real-time updates and notifications.
7. Implement search and filtering capabilities.
8. Add user authentication and permissions.
9. Add advanced features (reporting, analytics, etc.).
10. Optimize performance (leveraging Svelte's compile-time optimizations) and polish the UI.

Terminal-Style Interaction Requirements

• Keyboard-first navigation with extensive shortcut support
  • Function keys for main actions
  • Number keys for quick access to specific trailers
  • Arrow keys for navigation between spots
  • Tab/Shift+Tab for moving between interface sections
• Command modes similar to vim/terminal applications
• Support for quick commands via a command input field
• Instant response to user actions with minimal animations
• Ability to "tab through" all interactive elements
• Support for power users with advanced keyboard shortcuts

Accessibility Considerations

• Despite the terminal aesthetic, ensure screen reader compatibility
• Provide high contrast ratios that exceed WCAG AA standards
• Include alternative interaction methods alongside keyboard shortcuts
• Ensure all color-coded information also has text indicators
• Implement focused states that are clearly visible

Performance Considerations

• Optimize rendering for large yard layouts (Svelte helps here)
• Efficient state updates using Svelte stores to prevent unnecessary re-renders
• Progressive loading for large datasets
• Caching strategies for frequently accessed data

I'll create a comprehensive Virtual Yard Management System with a Bloomberg terminal aesthetic! This will include an interactive warehouse map using Svelte Flow, real-time appointment management, and terminal-style navigation with keyboard shortcuts. The system will feature drag-and-drop trailers, color-coded parking spots, and a dark, high-contrast interface optimized for warehouse operations.

Analyze the following errors and fix them:

• components/parking-spot.svelte:27:26: ERROR: Expected token > https://svelte.dev/e/expected_token components/status-filters.svelte:29:86: ERROR: [plugin: esbuild-svelte] This type of directive is not valid on components https://svelte.dev/e/component_invalid_directive components/trailer-node.svelte:24:26: ERROR: [plugin: esbuild-svelte] Expected token > https://svelte.dev/e/expected_token components/yard-map.svelte:4:49: ERROR: Could not resolve "@xyflow/svelte"

I'll fix these Svelte errors right away! The main issues are syntax errors with class bindings, invalid directive usage, and a missing dependency. I'll correct the class binding syntax for Svelte 5, fix the component directives, and replace the @xyflow/svelte dependency with a custom interactive map solution.

Analyze the following errors and fix them:

• components/status-filters.svelte:30:12: ERROR: Expected token } https://svelte.dev/e/expected_token

I'll fix the syntax error in the status filters component. The issue is with an incomplete Button tag that's missing its closing bracket and content.

Analyze the following errors and fix them:

• components/status-filters.svelte:33:4: ERROR: </Button> attempted to close an element that was not open https://svelte.dev/e/element_invalid_closing_tag

I'll fix the duplicate closing Button tag in the status filters component. There's an extra </Button> tag that needs to be removed.
