Add Advanced WYSIWYG Builder with AI collaboration by Copilot · Pull Request #60 · starspacegroup/hermes

Copilot · 2025-11-20T05:48:45Z

Implements a full-screen visual page builder to replace the basic WYSIWYG editor. Users can compose pages using drag-and-drop components, with live preview, device-specific rendering, and AI assistance.

Implementation

Core Architecture

Route: /admin/builder/[[pageId]] - Full-screen layout bypassing admin chrome
State: Immutable history with 50-step undo/redo, auto-save every 30s
Components: 6 new Svelte components (~1,300 LOC)
- AdvancedBuilder: Main orchestrator with keyboard shortcuts (Ctrl+Z/Y/S)
- BuilderToolbar: Device preview (mobile/tablet/desktop), save status, AI toggle
- BuilderCanvas: Live preview with widget manipulation controls
- BuilderSidebar: Component library (10 widgets) + layers panel with search/filtering
- BuilderPropertiesPanel: Wrapper for existing WidgetPropertiesPanel
- BuilderAIPanel: Chat interface for AI-assisted editing

Integration Points

Reuses existing WidgetRenderer for component preview
Leverages existing page/widget/revision APIs from src/lib/server/db/
Parses DBPageWidget (config as JSON string) to PageWidget (config as object)

Widget Operations

// Add widget from library
const newWidget: PageWidget = {
  id: `temp-${Date.now()}`,
  type: 'hero',
  config: { heading: 'Welcome', heroHeight: { desktop: '400px' } },
  position: widgets.length
};

// History tracked automatically
addToHistory(); // Captures { title, slug, widgets } snapshot

Screenshots

Empty canvas with component library:

Hero component added with controls visible:

Current Scope

✅ Phase 2 Complete:

Full-screen builder interface at /admin/builder
Component library with 10 widget types (Hero, Columns, Spacer, Divider, Heading, Text, Button, Image, Product, Product Grid)
Live canvas with widget selection/manipulation
Undo/Redo with change tracking
Device preview switcher
AI panel UI (backend integration pending)
Auto-save and unsaved changes indicator

🚧 Future Phases:

Drag-and-drop from library to canvas
Unlimited nesting with drop zones
Expand component library (50+ widgets)
AI backend integration for natural language editing
Visual revision diff
Breakpoint-specific style overrides
Symbol/component library for reusables

Technical Notes

Type Safety: Added type cast for DBPageWidget[] → PageWidget[] transformation in page load
Multi-tenant: Uses locals.siteId directly (not tenantContext)
API Compatibility: getPageRevisions() requires 3 args: (db, siteId, pageId)
Widget Types: Added missing types (features, pricing, cta) to default configs for WidgetType completeness

All 1,249 tests passing. Type checking clean except 2 expected warnings for unused exports (revisions, isNewPage - reserved for future phases).

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

Original prompt

This section details on the original issue you should resolve

<issue_title>Robust and usable WYSIWYG with AI collaborative editing</issue_title>
<issue_description>As a store admin (technical or non-technical), I want an extremely powerful, mobile-first, full-screen Advanced Page & Component WYSIWYG editor with unlimited nesting, live preview, and AI assistance, so that I can visually compose any page type (homepage, landing pages, collection pages, product pages overrides, blog posts, email templates, popups, etc.) using intuitive drag-and-drop, deeply nested sections, reusable components, and beautiful defaults — while retaining limitless customization of layout, styling, animations, logic, and functionality — all without writing code, yet allowing power users to drop in custom CSS/JS/HTML when desired.

Background & Vision

Hermes already has basic Page CRUD with revisions and a simple WYSIWYG. This new editor replaces and dramatically expands that system into a world-class, Framer/Webflow/Builder.io-level visual builder that feels magical on both desktop and mobile. The goal is zero-learning-curve for 90% of use cases (drag beautiful pre-built sections, tweak text/images, done) while giving power users unlimited depth (nested responsive grids, custom animations, conditional visibility, dynamic data binding, custom code components, etc.).

Scope for this Issue

Add new top-level route /admin/builder/:pageId? — full-screen, distraction-free, mobile-first builder canvas.
Add sidebar item Builder
Split-screen or adaptive layout:
- Mobile (<768px): Canvas only, bottom toolbar, tap-to-edit.
- Desktop: Left = layers/tree view + component library, Center = live canvas with device previews, Right = contextual properties panel.
Core editing paradigms:
- Select → edit inline (text, images) or in right panel.
- Drag-and-drop from component library into canvas or between existing containers.
- Unlimited nesting: A page should be able to include another page and a component should be able to include another component.
- Hover outlines + breadcrumbs for deep nesting.
Built-in component library with 60+ beautiful, production-ready components out of the box (Hero, Navbar, Footer, Product Grid, Testimonials, Image Gallery, Countdown Timer, Forms, etc.) — all fully responsive and theme-aware.
Global Styles & Theme editor (colors, typography, shadows, border radius, etc.) with live preview.
Reusable "Symbols" / Saved Components (create once, sync everywhere, override per-instance).
Revision history with visual diff and one-click revert.
Device-specific previews & editing (Desktop, Tablet, Mobile) with breakpoint-specific overrides.
Settings panel for adding AI provider API keys (OpenAI, Anthropic, Grok, etc.).
Export/import pages as JSON for backups or templates marketplace (future).

Acceptance Criteria

Technical Notes

Stack: SvelteKit + Konva.js or React-Grid-Layout alternative → pure Svelte with custom canvas using absolute positioning + Tailwind.
Storage: Pages stored as JSON AST in D1 + full HTML snapshot for revisions.
Rendering engine: Recursive Svelte component resolver from JSON AST (same ...
