# GarminSync UI Redesign Implementation Plan

## Overview
Transform the existing GarminSync web interface from the current bootstrap-based UI to a modern, clean design matching the provided mockups. The target design shows two main pages: Home (dashboard with statistics and sync controls) and Activities (data table view).

## Current State Analysis

### Existing Structure
- **Backend**: FastAPI with SQLAlchemy, scheduled daemon
- **Frontend**: Bootstrap 5 + jQuery, basic dashboard
- **Database**: SQLite with Activity, DaemonConfig, SyncLog models
- **Templates**: Jinja2 templates in `garminsync/web/templates/`
- **Static Assets**: Basic CSS/JS in `garminsync/web/static/`

### Current Pages
- Dashboard: Basic stats, daemon controls, logs
- Configuration: Daemon settings, cron scheduling  
- Logs: Paginated sync logs with filters

## Target Design Requirements

### Home Page Layout
```
┌─────────────────────────────────────────────────────────┐
│ Navigation: [Home] [Activities]                         │
├─────────────────────────────────────────────────────────┤
│ Left Sidebar (25%)    │ Right Content Area (75%)        │
│ ┌─────────────────┐   │ ┌─────────────────────────────┐ │
│ │ Sync Now        │   │ │                             │ │
│ │ (Blue Button)   │   │ │     Log Data Display        │ │

└─────────────────────────────────────────────────────────┘
```

### Activities Page Layout
```
┌─────────────────────────────────────────────────────────┐
│ Navigation: [Home] [Activities]                         │
├─────────────────────────────────────────────────────────┤

│ └─────────────────────────────────────────────────────┘ │
└─────────────────────────────────────────────────────────┘
```

## Implementation Plan

### Phase 1: Backend API Enhancements

#### 1.1 New API Endpoints
**File: `garminsync/web/routes.py`**

Add missing endpoints:
```python
@router.get("/activities")
async def get_activities(
    page: int = 1,
    per_page: int = 50,
    activity_type: str = None,
    date_from: str = None,
    date_to: str = None
):
    """Get paginated activities with filtering"""
    
@router.get("/activities/{activity_id}")  
async def get_activity_details(activity_id: int):
    """Get detailed activity information"""

@router.get("/dashboard/stats")
async def get_dashboard_stats():
    """Get comprehensive dashboard statistics"""
```

#### 1.2 Database Model Enhancements
**File: `garminsync/database.py`**

Enhance Activity model:
```python
class Activity(Base):
    __tablename__ = 'activities'
    
    activity_id = Column(Integer, primary_key=True)
    start_time = Column(String, nullable=False)
    activity_type = Column(String, nullable=True)  # NEW
    duration = Column(Integer, nullable=True)      # NEW (seconds)
    distance = Column(Float, nullable=True)        # NEW (meters)
    max_heart_rate = Column(Integer, nullable=True) # NEW
    avg_power = Column(Float, nullable=True)       # NEW
    calories = Column(Integer, nullable=True)      # NEW
    filename = Column(String, unique=True, nullable=True)
    downloaded = Column(Boolean, default=False, nullable=False)
    created_at = Column(String, nullable=False)
    last_sync = Column(String, nullable=True)
```

Add migration function to populate new fields from Garmin API.

### Phase 2: Frontend Architecture Redesign

#### 2.1 Modern CSS Framework
**File: `garminsync/web/static/style.css`**

Replace Bootstrap with custom CSS using modern techniques:
```css
/* CSS Variables for consistent theming */
:root {
    --primary-color: #007bff;
    --secondary-color: #6c757d;
    --success-color: #28a745;
    --danger-color: #dc3545;
    --light-gray: #f8f9fa;
    --dark-gray: #343a40;
    --border-radius: 8px;
    --box-shadow: 0 2px 10px rgba(0,0,0,0.1);
}

/* CSS Grid Layout System */
.container {
    max-width: 1200px;
    margin: 0 auto;
    padding: 0 20px;
}

.layout-grid {
    display: grid;
    grid-template-columns: 300px 1fr;
    gap: 20px;
    min-height: calc(100vh - 60px);
}

/* Modern Card Components */
.card {
    background: white;
    border-radius: var(--border-radius);
    box-shadow: var(--box-shadow);
    padding: 20px;
}

/* Responsive Design */
@media (max-width: 768px) {
    .layout-grid {
        grid-template-columns: 1fr;
    }
}
```

#### 2.2 Navigation Component
**File: `garminsync/web/static/navigation.js`**

Create dynamic navigation:
```javascript
class Navigation {
    constructor() {
        this.currentPage = this.getCurrentPage();
        this.render();
    }
    
    getCurrentPage() {
        return window.location.pathname === '/activities' ? 'activities' : 'home';
    }
    
    render() {
        const nav = document.querySelector('.navigation');
        nav.innerHTML = this.getNavigationHTML();
        this.attachEventListeners();
    }
    
    getNavigationHTML() {
        return `
            <nav class="nav-tabs">
                <button class="nav-tab ${this.currentPage === 'home' ? 'active' : ''}" 
                        data-page="home">Home</button>
                <button class="nav-tab ${this.currentPage === 'activities' ? 'active' : ''}" 
                        data-page="activities">Activities</button>
            </nav>
        `;
    }
}
```

### Phase 3: Home Page Implementation

#### 3.1 Home Page Template Redesign
**File: `garminsync/web/templates/dashboard.html`**

```html
{% extends "base.html" %}

{% block content %}
<div class="container">
    <div class="navigation"></div>
    
    <div class="layout-grid">
        <!-- Left Sidebar -->
        <div class="sidebar">
            <div class="card sync-card">
                <button id="sync-now-btn" class="btn btn-primary btn-large">
                    <i class="icon-sync"></i>
                    Sync Now
                </button>
                <div class="sync-status" id="sync-status">
                    Ready to sync
                </div>
            </div>
            
            <div class="card statistics-card">
                <h3>Statistics</h3>
                <div class="stat-item">
                    <label>Total Activities:</label>
                    <span id="total-activities">{{stats.total}}</span>
                </div>
                <div class="stat-item">
                    <label>Downloaded:</label>
                    <span id="downloaded-activities">{{stats.downloaded}}</span>
                </div>
                <div class="stat-item">
                    <label>Missing:</label>
                    <span id="missing-activities">{{stats.missing}}</span>
                </div>
            </div>
        </div>
        
        <!-- Right Content Area -->
        <div class="main-content">
            <div class="card log-display">
                <div class="card-header">
                    <h3>Log Data</h3>
                </div>
                <div class="log-content" id="log-content">
                    <!-- Real-time log updates will appear here -->
                </div>
            </div>
        </div>
    </div>
</div>
{% endblock %}
```

#### 3.2 Home Page JavaScript Controller
**File: `garminsync/web/static/home.js`**

```javascript
class HomePage {
    constructor() {
        this.logSocket = null;
        this.statsRefreshInterval = null;
        this.init();
    }
    
    init() {
        this.attachEventListeners();
        this.setupRealTimeUpdates();
        this.loadInitialData();
    }
    
    attachEventListeners() {
        document.getElementById('sync-now-btn').addEventListener('click', 
            () => this.triggerSync());
    }
    
    async triggerSync() {
        const btn = document.getElementById('sync-now-btn');
        const status = document.getElementById('sync-status');
        
        btn.disabled = true;
        btn.innerHTML = '<i class="icon-loading"></i> Syncing...';
        status.textContent = 'Sync in progress...';
        
        try {
            const response = await fetch('/api/sync/trigger', {method: 'POST'});
            const result = await response.json();
            
            if (response.ok) {
                status.textContent = 'Sync completed successfully';
                this.updateStats();
            } else {
                throw new Error(result.detail || 'Sync failed');
            }
        } catch (error) {
            status.textContent = `Sync failed: ${error.message}`;
        } finally {
            btn.disabled = false;
            btn.innerHTML = '<i class="icon-sync"></i> Sync Now';
        }
    }
    
    setupRealTimeUpdates() {
        // Poll for log updates every 5 seconds during active operations
        this.startLogPolling();
        
        // Update stats every 30 seconds
        this.statsRefreshInterval = setInterval(() => {
            this.updateStats();
        }, 30000);
    }
    
    async startLogPolling() {
        // Implementation for real-time log updates
    }
    
    async updateStats() {
        try {
            const response = await fetch('/api/activities/stats');
            const stats = await response.json();
            
            document.getElementById('total-activities').textContent = stats.total;
            document.getElementById('downloaded-activities').textContent = stats.downloaded;
            document.getElementById('missing-activities').textContent = stats.missing;
        } catch (error) {
            console.error('Failed to update stats:', error);
        }
    }
}
```

### Phase 4: Activities Page Implementation

#### 4.1 Activities Page Template
**File: `garminsync/web/templates/activities.html`**

```html
{% extends "base.html" %}

{% block content %}

                            <th>Duration</th>
                            <th>Distance</th>
                            <th>Max HR</th>
                            <th>Power</th>
                        </tr>

                </table>
            </div>
            
            <div class="pagination-container">
                <div class="pagination" id="pagination">
                    <!-- Pagination controls -->

        this.setupEventListeners();
    }
    
    async loadActivities() {
        try {
            const params = new URLSearchParams({
                page: this.currentPage,
                per_page: this.pageSize,
                ...this.filters

            const response = await fetch(`/api/activities?${params}`);
            const data = await response.json();
            
            this.activities = data.activities;
            this.totalPages = Math.ceil(data.total / this.pageSize);

        }
    }
    
    renderTable() {
        const tbody = document.getElementById('activities-tbody');
        tbody.innerHTML = '';
        
        this.activities.forEach((activity, index) => {
            const row = this.createTableRow(activity, index);
            tbody.appendChild(row);
        });
    }
    
    createTableRow(activity, index) {
        const row = document.createElement('tr');
        row.className = index % 2 === 0 ? 'row-even' : 'row-odd';
        
        row.innerHTML = `

    }
    
    formatPower(watts) {
        return watts ? `${Math.round(watts)}W` : '-';
    }
}
```

### Phase 5: Styling and Visual Polish

#### 5.1 Advanced CSS Styling
**File: `garminsync/web/static/components.css`**

```css
/* Table Styling */
.activities-table {
    width: 100%;
    border-collapse: collapse;
    font-size: 14px;
}

.activities-table thead {
    background-color: #000;
    color: white;
}

.activities-table th {
    padding: 12px 16px;
    text-align: left;
    font-weight: 600;
    border-right: 1px solid #333;
}

.activities-table td {
    padding: 12px 16px;
    border-bottom: 1px solid #eee;
}

.activities-table .row-even {
    background-color: #f8f9fa;
}

.activities-table .row-odd {
    background-color: #ffffff;
}

/* Sync Button Styling */
.btn-primary.btn-large {
    width: 100%;
    padding: 15px;
    font-size: 16px;
    font-weight: 600;
    border-radius: var(--border-radius);
    background: linear-gradient(135deg, #007bff 0%, #0056b3 100%);
    border: none;
    color: white;
    cursor: pointer;
    transition: all 0.2s ease;
}

.btn-primary.btn-large:hover {
    transform: translateY(-2px);
    box-shadow: 0 4px 12px rgba(0,123,255,0.3);
}

.btn-primary.btn-large:disabled {
    opacity: 0.6;
    cursor: not-allowed;
    transform: none;
}

/* Statistics Card */
.statistics-card .stat-item {
    display: flex;
    justify-content: space-between;
    margin-bottom: 10px;
    padding: 8px 0;
    border-bottom: 1px solid #eee;
}

.statistics-card .stat-item:last-child {
    border-bottom: none;
}

.statistics-card label {
    font-weight: 500;
    color: #666;
}

.statistics-card span {
    font-weight: 600;
    color: #333;
}
```

#### 5.2 Responsive Design
**File: `garminsync/web/static/responsive.css`**

```css
/* Mobile-first responsive design */
@media (max-width: 768px) {
    .layout-grid {
        grid-template-columns: 1fr;
        gap: 15px;
    }
    
    .sidebar {
        order: 2;
    }
    
    .main-content {
        order: 1;
    }
    
    .activities-table {
        font-size: 12px;
    }
    
    .activities-table th,
    .activities-table td {
        padding: 8px 10px;
    }
}

@media (max-width: 480px) {
    .activities-table {
        display: block;
        overflow-x: auto;
        white-space: nowrap;
    }
}
```

### Phase 6: Integration and Testing

#### 6.1 Updated Base Template
**File: `garminsync/web/templates/base.html`**

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>GarminSync</title>
    <link href="/static/style.css" rel="stylesheet">
    <link href="/static/components.css" rel="stylesheet">
    <link href="/static/responsive.css" rel="stylesheet">
</head>
<body>
    {% block content %}{% endblock %}
    
    <script src="/static/navigation.js"></script>
    <script src="/static/utils.js"></script>
    
    {% block page_scripts %}{% endblock %}
</body>
</html>
```

#### 6.2 App Router Updates
**File: `garminsync/web/app.py`**

Add activities route:
```python
@app.get("/activities")
async def activities_page(request: Request):
    """Activities page route"""
    if not templates:
        return JSONResponse({"message": "Activities endpoint"})
    
    return templates.TemplateResponse("activities.html", {
        "request": request
    })
```

### Phase 7: Performance Optimization

#### 7.1 Lazy Loading and Pagination
- Implement virtual scrolling for large activity datasets
