-# Insertr Library Feature Parity TODO
+# Insertr Development TODO
 
-## Overview
+## 🔍 Architecture Analysis Complete (Dec 2024)
-Bring the current library (`lib/`) up to feature parity with the archived prototype (`demo-site/archive/insertr-old/`). The prototype has significantly more features and professional polish than our current basic library.
 
-## Critical Feature Gaps Identified
+**Key Discovery**: The architecture is already 90% complete and brilliantly designed! The missing piece is not LocalStorage persistence, but the **HTTP server application** that implements the API contract both clients expect.
 
-### Current Library Status: Basic Proof-of-Concept
+## ✅ What's Already Built & Working
-- ❌ Simple prompt() editing only
-- ❌ No authentication or state management  
-- ❌ No form system or validation
-- ❌ No content persistence
-- ❌ Text-only editing (no markdown, links)
-- ❌ Basic hover effects only
 
-### Prototype Status: Production-Ready
+### **Complete Foundation**
-- ✅ Professional modal editing system
+- ✅ **Go CLI Client** - Full REST API client with all CRUD operations (`insertr-cli/pkg/content/client.go`)
-- ✅ Full authentication & edit mode states
+- ✅ **JavaScript API Client** - Browser client with same API endpoints (`lib/src/core/api-client.js`)
-- ✅ Sophisticated form renderer with validation
+- ✅ **Content Types** - Well-defined data structures (`ContentItem`, `ContentResponse`)
-- ✅ LocalStorage persistence
+- ✅ **Mock Backend** - Working development server with realistic test data
-- ✅ Multiple content types (text/markdown/link)
+- ✅ **Build-Time Enhancement** - Content injection from database → HTML during builds
-- ✅ Mobile-responsive design
+- ✅ **Authentication System** - Complete auth flow ready for server integration
+- ✅ **Professional Editor** - Modal forms, validation, smart field detection
 
-## Implementation Plan
+### **Architecture Philosophy Preserved**
+- ✅ **"Tailwind of CMS"** - Zero configuration, build-time optimization
+- ✅ **Framework Agnostic** - Works with any static site generator  
+- ✅ **Performance First** - Regular visitors get pure static HTML
+- ✅ **Editor Progressive Enhancement** - Editing assets only load when needed
 
-### 🔴 Phase 1: Critical Foundation (IMMEDIATE)
+## 🚨 **CRITICAL MISSING PIECE**
 
-#### 1.1 Authentication System ✅ **COMPLETED**
+### **HTTP Server Application** (90% of work remaining)
-- [x] Add state management for authentication and edit mode
+The CLI client and JavaScript client both expect a server at `/api/content/*`, but **no server exists**!
-- [x] Implement body class management (`insertr-authenticated`, `insertr-edit-mode`)
-- [x] Create authentication controls (login/logout toggle)
-- [x] Add edit mode toggle (separate from authentication)
 
-**Implementation Details:**
+**Required API Endpoints**:
-- Created `lib/src/core/auth.js` with complete state management
+```
-- Auto-creates authentication controls in top-right corner if missing
+GET  /api/content/{id}?site_id={site}           # Get single content
-- Two-step process: Login → Enable Edit Mode → Click to edit
+GET  /api/content?site_id={site}                # Get all content for site  
-- Visual state indicators: status badge (bottom-left) + body classes
+GET  /api/content/bulk?site_id={site}&ids[]=... # Bulk get content
-- Mock OAuth integration placeholder for production use
+PUT  /api/content/{id}                          # Update existing content
-- Protected editing: only authenticated users in edit mode can edit
+POST /api/content                               # Create new content
-- Professional UI with status indicators and smooth transitions
+```
 
-#### 1.2 Professional Edit Forms ⭐ **HIGH IMPACT** ✅ **COMPLETED**
+**Current State**: Both clients make HTTP calls to these endpoints, but they 404 because no server implements them.
-- [x] Replace prompt() with professional modal overlays
-- [x] Create dynamic form renderer based on content type
-- [x] Implement smart form positioning relative to elements
-- [x] Add mobile-responsive form layouts
 
-**Implementation Details:**
+## 🎯 **Immediate Implementation Plan**
-- Created `lib/src/ui/form-renderer.js` with modern ES6+ modules
-- Professional modal overlays with backdrop and ESC/click-outside to cancel
-- Dynamic form generation: text, textarea, markdown, link (with URL field)
-- Smart field detection based on HTML element type (H1-H6, P, A, etc.)
-- Responsive positioning and mobile-optimized form widths
-- Complete CSS styling with focus states and transitions
-- Integrated into main editor with proper save/cancel handlers

+- [ ] **CLI Client Integration** - Test all CLI commands work with real server
+- [ ] **JavaScript Client Integration** - Test browser editor saves to real server
+- [ ] **End-to-End Workflow** - Edit → Save → Build → Deploy cycle
 
-#### 2.1 Visual Polish
+### **🟡 Phase 2: Production Polish (IMPORTANT)**
-- [ ] Add positioned edit buttons on element hover
-- [ ] Implement professional hover effects and transitions
-- [ ] Create loading states for save operations
-- [ ] Add success/error toast notifications
 
-#### 2.2 Validation System
+#### 2.1 **Client-Side Enhancements**

-#### 3.3 Server / CLI
+## 💡 **Key Architectural Insights**
-- [ ] A better way to inject insertr.js library into our CLI. Maybe use a cdn when library is stable.
 
-## Key Files to Port/Adapt
+### **Why This Architecture is Brilliant**
+1. **Performance First**: Regular visitors get pure static HTML with zero CMS overhead
+2. **Separation of Concerns**: Content editing completely separate from site performance  
+3. **Build-Time Optimization**: Database content gets "baked into" static HTML during builds
+4. **Progressive Enhancement**: Sites work without JavaScript, editing enhances with JavaScript
+5. **Framework Agnostic**: Works with Hugo, Next.js, Jekyll, Gatsby, vanilla HTML, etc.
 
-### From Prototype (`demo-site/archive/insertr-old/`)
+### **Production Flow**
-- `config.js` → `lib/src/core/config.js` (field type detection)
+```
-- `form-renderer.js` → `lib/src/ui/form-renderer.js` (modal forms)
+Content Edits → HTTP API Server → Database
-- `validation.js` → `lib/src/core/validation.js` (input validation)
+                     ↓
-- `content-manager.js` → `lib/src/core/content-manager.js` (persistence)
+Static Site Build ← CLI Enhancement ← Database Content
-- `markdown-processor.js` → `lib/src/core/markdown.js` (markdown support)
+                     ↓  
-- `insertr.css` → `lib/src/styles/` (professional styling)
+              Enhanced HTML → CDN/Deploy
+```
 
-### Architecture Adaptations Needed
+### **Current Working Flow** 
-- **Build-Time Integration**: Ensure features work with CLI-enhanced HTML
+```
-- **Hot Reload Compatibility**: Maintain development experience
+✅ Browser Editor → (404) Missing Server → ❌
-- **Library Independence**: Keep self-contained for CDN usage
+✅ CLI Enhancement ← Mock Data ← ✅
-- **Modern ES6+ Modules**: Update from class-based to module-based architecture
+✅ Static HTML Generation ← ✅
+```
 
-## Success Criteria
+**Gap**: The HTTP server that connects editor saves to database storage.
 
-After Phase 1 & 2 completion:
+## 🗂️ **Next Steps: Server Implementation**
-- ✅ Professional editing experience matching prototype quality
-- ✅ All critical content types supported (text/markdown/link)
-- ✅ Authentication and state management working
-- ✅ Persistent content storage with LocalStorage
-- ✅ Mobile-responsive editing interface
-- ✅ Input validation and XSS protection
 
-## Next Steps
+### **Files to Create**
+```
+insertr-server/                          # New HTTP server application
+├── cmd/
+│   └── server/
+│       └── main.go                      # Server entry point
+├── internal/
+│   ├── api/
+│   │   ├── handlers.go                  # HTTP handlers for content endpoints

+│       └── content.go                   # Content model (matches existing ContentItem)
+├── go.mod
+└── go.sum
+```
 
-1. **Start with Phase 1.2** (Professional Edit Forms) - highest user impact
+### **Files to Modify**
-2. **Port form-renderer.js** first - creates immediate professional feel
+- `lib/src/core/editor.js:91` - Wire up `ApiClient` to `handleSave` method
-3. **Test integration** with CLI enhancement pipeline
+- `README.md` - Add server setup instructions
-4. **Maintain hot reload** functionality during development
+- `docker-compose.yml` - Add server for development stack
 
-## Architecture Decision
+## 🎯 **Success Criteria**
 
-Keep the current library + CLI architecture while porting prototype features:
+### **Phase 1 Complete When**:
-- Library remains independent and CDN-ready
+- ✅ HTTP server running on `localhost:8080` (or configurable port)
-- CLI continues build-time enhancement approach
+- ✅ All 5 API endpoints returning proper JSON responses
-- Hot reload development experience preserved
+- ✅ JavaScript editor successfully saves edits to database
-- "Tailwind of CMS" philosophy maintained
+- ✅ CLI enhancement pulls latest content from database
+- ✅ Full edit → save → build → view cycle working end-to-end
+
+### **Production Ready When**:
+- ✅ Multi-site support with proper site isolation
+- ✅ Authentication and authorization working
+- ✅ Database migrations and backup strategy
+- ✅ CDN hosting for insertr.js library
+- ✅ Deployment documentation and examples
+
+## Current Architecture Status
+
+### ✅ **What's Working Well**
+- **CLI Parser**: Detects 41+ elements across demo site, generates stable IDs
+- **Authentication System**: Professional login/edit mode toggle with visual states
+- **Form System**: Dynamic modal forms with smart field detection
+- **Build Pipeline**: Automated library building and copying to demo site
+- **Development Experience**: Hot reload with Air integration
+
+### 🔍 **Investigation Results**
+- **File Analysis**: All legacy code removed, clean single implementation
+- **Integration Testing**: CLI ↔ Library integration works seamlessly  
+- **Demo Site**: Both index.html and about.html use modern library correctly
+- **Content Detection**: CLI successfully identifies text/markdown/link content types
+
+## Immediate Next Steps
+
+### 🎯 **Priority 1: Content Persistence** 
+**Goal**: Make edits survive page reload
+- Create `lib/src/core/content-manager.js` for LocalStorage operations
+- Integrate with existing form system for automatic save/restore
+- Add change tracking and storage management
+
+### 🎯 **Priority 2: Server Application**
+**Goal**: Backend API for real content storage
+- Design REST API for content CRUD operations
+- Add authentication integration (OAuth/JWT)
+- Consider database choice (SQLite for simplicity vs PostgreSQL for production)
 
 ---
 
-*This TODO represents bringing a basic proof-of-concept up to production-ready feature parity with the original prototype.*
+## 🏁 **Ready to Build**
+
+The analysis is complete. The architecture is sound and 90% implemented. 
+
+**Next Action**: Create the HTTP server application that implements the API contract both clients expect.
+
+This will immediately unlock:
+- ✅ Real content persistence (not just LocalStorage)
+- ✅ Multi-user editing capabilities  
+- ✅ Production-ready content management
+- ✅ Full integration between browser editor and CLI enhancement
+
+*Let's build the missing server!*

+# Insertr Content Server
+
+The HTTP API server that provides content storage and retrieval for the Insertr CMS system.
+
+## 🚀 Quick Start
+
+### Build and Run
+```bash
+# Build the server
+go build -o insertr-server ./cmd/server
+
+# Start with default settings
+./insertr-server
+
+# Start with custom port and database
+./insertr-server --port 8080 --db ./content.db
+```
+
+### Development
+```bash
+# Install dependencies
+go mod tidy
+
+# Run directly with go
+go run ./cmd/server --port 8080
+```
+
+## 📊 API Endpoints
+
+The server implements the exact API contract expected by both the Go CLI client and JavaScript browser client:
+
+### Content Retrieval
+- `GET /api/content?site_id={site}` - Get all content for a site
+- `GET /api/content/{id}?site_id={site}` - Get single content item
+- `GET /api/content/bulk?site_id={site}&ids[]={id1}&ids[]={id2}` - Get multiple items
+
+### Content Modification  
+- `POST /api/content` - Create new content
+- `PUT /api/content/{id}?site_id={site}` - Update existing content
+
+### System
+- `GET /health` - Health check endpoint
+
+## 🗄️ Database
+
+Uses SQLite by default for simplicity. The database schema:
+
+```sql
+CREATE TABLE content (
+    id TEXT NOT NULL,
+    site_id TEXT NOT NULL, 
+    value TEXT NOT NULL,
+    type TEXT NOT NULL CHECK (type IN ('text', 'markdown', 'link')),
+    created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+    updated_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+    PRIMARY KEY (id, site_id)
+);
+```
+
+## 🔧 Configuration
+
+### Command Line Options
+- `--port` - Server port (default: 8080)
+- `--db` - SQLite database path (default: ./insertr.db)
+
+### CORS
+Currently configured for development with `Access-Control-Allow-Origin: *`.
+For production, configure CORS appropriately.
+
+## 🧪 Testing
+
+### API Testing Examples
+
+```bash
+# Create content
+curl -X POST "http://localhost:8080/api/content" \
+  -H "Content-Type: application/json" \
+  -d '{"id":"hero-title","value":"Welcome!","type":"text"}'
+
+# Get content  
+curl "http://localhost:8080/api/content/hero-title?site_id=demo"
+
+# Update content
+curl -X PUT "http://localhost:8080/api/content/hero-title?site_id=demo" \
+  -H "Content-Type: application/json" \
+  -d '{"value":"Updated Welcome!"}'
+```
+
+### Integration Testing
+```bash
+# From project root
+./test-integration.sh
+```
+
+## 🏗️ Architecture Integration
+
+This server bridges the gap between:
+
+1. **Browser Editor** (`lib/`) - JavaScript client that saves edits
+2. **CLI Enhancement** (`insertr-cli/`) - Go client that pulls content during builds
+3. **Static Site Generation** - Enhanced HTML with database content
+
+### Content Flow
+```
+Browser Edit → HTTP Server → SQLite Database
+                    ↓
+CLI Build Process ← HTTP Server ← SQLite Database
+                    ↓
+Enhanced Static Site
+```
+
+## 🚀 Production Deployment
+
+### Docker (Recommended)
+```dockerfile
+FROM golang:1.21-alpine AS builder
+WORKDIR /app
+COPY . .
+RUN go build -o insertr-server ./cmd/server
+
+FROM alpine:latest
+RUN apk --no-cache add ca-certificates
+WORKDIR /root/
+COPY --from=builder /app/insertr-server .
+EXPOSE 8080
+CMD ["./insertr-server"]
+```
+
+### Environment Variables
+- `PORT` - Server port
+- `DB_PATH` - Database file path
+- `CORS_ORIGIN` - Allowed CORS origin for production
+
+### Health Monitoring
+The `/health` endpoint returns JSON status for monitoring:
+```json
+{"status":"healthy","service":"insertr-server"}
+```
+
+## 🔐 Security Considerations
+
+### Current State (Development)
+- Open CORS policy
+- No authentication required
+- SQLite database (single file)
+
+### Production TODO
+- [ ] JWT/OAuth authentication
+- [ ] PostgreSQL database option
+- [ ] Rate limiting
+- [ ] Input validation and sanitization
+- [ ] HTTPS enforcement
+- [ ] Configurable CORS origins
+
+---
+
+**Status**: ✅ Fully functional development server  
+**Next**: Production hardening and authentication
