# HTML Componentization Gameplan
*Saved for future implementation*
## **Executive Summary**
**Problem**: 40+ HTML files with 80% duplicate code (sidebar, header, footer, navigation)
**Solution**: Extract common components into reusable templates
**Impact**: Dramatically improve maintainability, development speed, and consistency
---
## **Current Structure Analysis**
### **Repeating Components Identified**
1. **HTML Head Section** (~15 lines)
- Meta tags, title, Vite imports
- Same across all files except page-specific titles
2. **Sidebar Navigation** (~140 lines)
- Logo and branding
- User profile section
- Main navigation menu
- Sidebar footer buttons
3. **Top Navigation** (~120 lines)
- Hamburger menu toggle
- User profile dropdown
- Notifications dropdown
- Messages list
4. **Footer** (~10 lines)
- Copyright and attribution
- Consistent across all pages
5. **Body Wrapper Structure** (~20 lines)
- Container and layout divs
- Same Bootstrap 5 structure
### **Code Duplication Stats**
- **Total Files**: 40+ HTML files
- **Duplicate Code**: ~80% (300+ lines per file)
- **Unique Content**: ~20% (varying by page complexity)
- **Maintenance Burden**: Updates require touching 40+ files
---
## **Implementation Options**
### **Option 1: Template Engine (Recommended)**
**Technology**: Eleventy (11ty) or Handlebars
**Benefits**: Static generation, great documentation, minimal learning curve
```html
<!-- layouts/base.html -->
<!DOCTYPE html>
<html lang="en">
<head>
{{> head title=title }}
</head>
<body class="nav-md">
<div class="container body">
<div class="main_container">
{{> sidebar activeMenu=activeMenu }}
{{> topnav user=user }}
<div class="right_col" role="main">
<div class="page_title">
<div class="title_left">
<h3>{{title}}</h3>
</div>
</div>
<div class="clearfix"></div>
{{{ content }}}
</div>
{{> footer }}
</div>
</div>
</body>
</html>
```
### **Option 2: Server-Side Includes**
**Technology**: PHP includes or SSI
**Benefits**: Simple, widely supported
```php
<?php
$pageTitle = "Dashboard";
$activeMenu = "home";
include 'components/head.php';
?>
<body class="nav-md">
<?php include 'components/sidebar.php'; ?>
<?php include 'components/topnav.php'; ?>
<!-- Page content here -->
<?php include 'components/footer.php'; ?>
</body>
```
### **Option 3: Build Script**
**Technology**: Node.js build script
**Benefits**: Custom control, integrates with existing Vite setup
```javascript
// build-components.js
const fs = require('fs');
const path = require('path');
function buildPage(pageContent, config) {
const template = fs.readFileSync('templates/base.html', 'utf8');
const sidebar = fs.readFileSync('components/sidebar.html', 'utf8');
const topnav = fs.readFileSync('components/topnav.html', 'utf8');
const footer = fs.readFileSync('components/footer.html', 'utf8');
return template
.replace('{{sidebar}}', sidebar)
.replace('{{topnav}}', topnav)
.replace('{{footer}}', footer)
.replace('{{content}}', pageContent)
.replace('{{title}}', config.title)
.replace('{{activeMenu}}', config.activeMenu);
}
```
---
## **Implementation Plan**
### **Phase 1: Component Extraction**
**Duration**: 2-3 hours
1. **Create directory structure**:
```
components/
├── head.html
├── sidebar.html
├── topnav.html
└── footer.html
templates/
└── base.html
pages/
├── dashboard-content.html
├── forms-content.html
└── ... (page-specific content)
```
2. **Extract sidebar component** (lines 21-160 from existing files):
```html
<!-- components/sidebar.html -->
<div class="col-md-3 left_col">
<div class="left_col scroll-view">
<!-- navbar brand -->
<div class="navbar nav_title" style="border: 0;">
<a href="index.html" class="site_title">
<i class="fas fa-paw"></i> <span>Gentelella Alela!</span>
</a>
</div>
<!-- ... rest of sidebar -->
</div>
</div>
```
3. **Extract other components** following the same pattern
### **Phase 2: Template System Setup**
**Duration**: 1-2 hours
1. **Install template engine**:
```bash
npm install @11ty/eleventy --save-dev
```
2. **Configure build process**:
```javascript
// .eleventy.js
module.exports = function(eleventyConfig) {
eleventyConfig.addPassthroughCopy("src");
eleventyConfig.addPassthroughCopy("images");
return {
dir: {
input: "pages",
output: "production",
includes: "../components",
layouts: "../templates"
}
};
};
```
### **Phase 3: Convert Pages**
**Duration**: 4-6 hours
1. **Start with simple pages**:
- `plain_page.html``pages/plain-page.md`
- `page_404.html``pages/404.md`
2. **Convert dashboard pages**:
- Extract unique content from `index.html`, `index2.html`, `index3.html`
- Create page-specific data files for dynamic content
3. **Handle complex pages**:
- `form_advanced.html` (lots of unique JavaScript)
- `tables_dynamic.html` (DataTables integration)
### **Phase 4: Dynamic Features**
**Duration**: 2-3 hours
1. **Active menu highlighting**:
```html
<li class="{{#if (eq activeMenu 'home')}}active{{/if}}">
<a href="index.html">Dashboard</a>
</li>
```
2. **Page-specific titles and meta tags**:
```yaml
---
title: "Dashboard - Gentelella"
description: "Main dashboard overview"
activeMenu: "home"
scripts: ["dashboard-specific.js"]
---
```
3. **Conditional content**:
```html
{{#if showNotifications}}
{{> notifications-dropdown}}
{{/if}}
```
---
## **Benefits After Implementation**
### **Immediate Benefits**
- **Single Point of Updates**: Change navigation in one file, applies everywhere
- **Consistency Guaranteed**: No more forgetting to update one file
- **Development Speed**: New pages only need content, not full HTML structure
- **Bug Fixes**: Fix header/sidebar issues once, not 40+ times
### **Long-term Benefits**
- **Easy Rebranding**: Logo, colors, layout changes in components only
- **A/B Testing**: Test different navigation layouts easily
- **Team Collaboration**: Multiple developers can work without conflicts
- **Scalability**: Add new pages without duplicating boilerplate
### **Technical Benefits**
- **Smaller Git Diffs**: Only content changes tracked, not structure
- **Better Caching**: Separate content from layout for browser caching
- **SEO Improvements**: Consistent meta tags and structure
- **Accessibility**: Implement improvements across all pages simultaneously
---
## **Migration Strategy**
### **Risk Mitigation**
1. **Backup Strategy**: Keep original files in `production-backup/`
2. **Gradual Migration**: Convert 5-10 pages at a time
3. **Testing Protocol**: Compare generated vs original HTML
4. **Rollback Plan**: Git branches for easy reversion
### **Quality Assurance**
1. **Visual Regression Testing**: Screenshot comparison
2. **Functionality Testing**: Ensure all JavaScript still works
3. **Responsive Testing**: Mobile/tablet layouts intact
4. **Cross-browser Testing**: Same compatibility as originals
### **Performance Considerations**
1. **Build Time**: Template compilation should be fast (<5 seconds)
2. **Output Size**: Generated HTML should be identical in size
3. **Development Speed**: Hot reload for template changes
4. **Maintenance**: Clear documentation for future developers
---
## **Recommended Next Steps**
### **When Ready to Implement**
1. **Start Small**: Begin with 3-5 simple pages (plain_page, 404, etc.)
2. **Choose Technology**: Recommend Eleventy for its simplicity
3. **Set Timeline**: Allocate 1-2 days for full implementation
4. **Team Training**: Ensure team understands new workflow
### **Prerequisites**
- [ ] Backup current production files
- [ ] Choose template engine (Eleventy recommended)
- [ ] Set up development environment
- [ ] Plan testing strategy
