**CoolAdmin** is a modern, responsive, and feature-rich admin dashboard template built with **Bootstrap 5.3.8** and **vanilla JavaScript**. Originally rewritten in 2025 to drop jQuery and Bootstrap 4; refreshed in 2026 (v3.0) with a leaner dependency set, accessibility improvements, and per-page SEO metadata; extended in v3.1 with a modern design overlay, a command palette, a theme switcher, loading skeletons, and 11 new pages including kanban, profile, pricing, invoice, and a working data table; refactored in v3.2 with a Pug + SCSS source pipeline so the sidebar nav and shared chrome live in a single editable file.

## What's New in v3.2.0 (May 2026)

### Source pipeline — Pug templates, SCSS partials, Vite dev server

You can still clone the repo and open `index.html` — built HTML and CSS ship in the repo root with zero build step. But contributors now get:

- **One-file menu editing.** Add, rename, or reorder a sidebar item in `src/pug/partials/_nav-data.pug` and it propagates to both the desktop sidebar and the mobile nav on every page. No more touching 24 HTML files for a single nav change.
- **Pug layouts + partials.** Shared `<head>` (with per-page meta mixin), sidebar, topbar, mobile header, and footer scripts live in `src/pug/partials/`. Two layouts (`_default.pug` for dashboards, `_auth.pug` for login/register/forget-pass). Pages set `block variables` (title, description, activePage) and fill in `block content`.
- **SCSS split into 56 partials.** `theme.scss` (legacy) decomposes into 20 ITCSS partials (`_variables`, `_generic`, `_elements`, `_objects`, fourteen `components/_*`, `_utilities`, `_modern-additions`). `theme-2026.scss` (modern overlay) decomposes into 36 partials under `src/scss/2026/`. Sass compiles them back to byte-equivalent CSS (verified via minified diff).
- **Vite dev server with HMR.** `npm run dev` runs Pug watcher + sass watcher + Vite in parallel. Edit a partial or a SCSS variable, see the browser reload in milliseconds.

Addresses [issue #35](https://github.com/puikinsh/CoolAdmin/issues/35). Three pages are migrated to Pug as a proof-of-concept (`index`, `login`, `table`); the other 21 remain hand-written HTML at the repo root and continue to work unchanged. Each can be migrated incrementally — ~10 lines of Pug plus an inner-content extraction.

## What's New in v3.1.0 (May 2026)

### A modern application shell on top of the audited base

- **`theme-2026.css` — single-file design overlay.** Activated by `<body class="theme-2026">`. Inter font, brand-blue palette, modern card and button patterns, stat-cards, profile cards, kanban board, project lists, deadline lists, email split-pane reader. Original styles still ship for anyone who prefers them.
- **Cmd+K command palette** with 31+ commands, keyboard navigation, and fuzzy match.
- **6-preset color theme switcher** (Cmd/Ctrl+Shift+T) — Default Blue, Indigo, Emerald, Sunset, Rose, Slate. Persists in `localStorage`.
- **Toast notification system.** `window.toast.success(...)`, `.info`, `.warning`, `.error`. Stack of up to 5, click-to-dismiss.
- **Loading skeletons.** All four dashboards have a working "Refresh" button that swaps KPI cards and the primary chart to shimmer placeholders for ~1.2s, then re-renders the real charts via `window.__coolReinit()`.
- **Self-updating calendar.** Events generated relative to today, so the demo never goes stale.
- **Interactive inbox** with a 12-message split-pane reader, star/archive/delete/reply.
- **11 new pages.** `profile`, `kanban` (HTML5 drag-and-drop), `pricing`, `invoice` (print-ready), `data-table` (sort/filter/pagination), `wizard`, `docs` (TOC scrollspy), `notifications`, plus `404`, `500`, `maintenance`.
- **Distinct dashboards.** `index2` is now Sales pipeline; `index3` is Marketing analytics; `index4` is Projects. Each has its own KPIs, primary chart, and supporting widgets.
- **Component pages rebuilt** with modern interactive demos (async loading button, 6 modal variants, three tab styles, SVG circular-progress rings, brand-color form switches).

## What's New in v3.0.0 (May 2026)

### Audit pass — leaner, faster, more accessible

- **Cut ~260 KB of JS per page** by removing unused libraries (AOS, Perfect Scrollbar, Swiper) that were loaded on every page but never instantiated.
- **Single icon font.** Dropped the legacy Material Design Iconic Font (`zmdi-*`); migrated all 353 icon usages to Font Awesome 7.
- **Accessibility upgrades.** Skip-to-main-content link, `<main>` landmark, `aria-label` on icon-only buttons, label-for binding + autocomplete on auth forms, `:focus-visible` outlines.
- **Per-page SEO.** Unique title and description for every page. Open Graph + Twitter Card tags. Auth pages flagged `noindex`.
- **Design tokens.** New `:root` block in `theme.css` — brand, surface, text, and shadow custom properties. Foundation for retheming and dark mode (`<html data-bs-theme="dark">`).
- **Cleaner JS.** `main-vanilla.js` rewritten (1003 → 551 lines) with a shared sparkline-options factory; `bootstrap5-init.js` slimmed (69 → 12 lines); plugin styles moved out of injected `<style>` tags into `theme.css`. All 35 `console.log` calls removed.
- **CSS sweep.** 718 obsolete `-webkit-` / `-moz-` / `-ms-` declarations removed; `theme.css` is 33 KB smaller.

## Quick Start

CoolAdmin ships **two ways to run it**, depending on whether you want to edit shared partials or just preview the built template.

### As an end user — no Node required

Built HTML and CSS live in the repo root. Clone, serve statically, open in a browser:

```bash
git clone https://github.com/puikinsh/CoolAdmin.git
cd CoolAdmin
python3 -m http.server 8000      # or:  npx serve .
```

Then open `http://localhost:8000/index.html`. Every page (24 in total) works without a toolchain.

### As a contributor — Pug + SCSS + Vite

To edit shared layouts, sidebar nav, or SCSS partials, run the source pipeline:

```bash
npm install                      # one-time
npm run dev                      # starts pug-watch + sass-watch + Vite dev server at :3000
```

`npm run dev` runs three watchers concurrently:

- **Pug** — `node scripts/build-pug.js --watch` recompiles root `*.html` when anything in `src/pug/` changes.
- **Sass** — `sass --watch src/scss/*.scss:css/*.css` recompiles `css/theme.css` and `css/theme-2026.css` from `src/scss/` sources.
- **Vite** — dev server with HMR at `http://localhost:3000`, auto-opens `index.html`.

Edit `src/pug/partials/_nav-data.pug` to change the sidebar — the change appears on every page automatically.

For a production rebuild without watchers:

```bash
npm run build                    # one-shot pug + sass build
```

### Source layout

```

└── scripts/
    └── build-pug.js             # Node script: src/pug/pages/*.pug → root *.html
```

### Adding a new page (Pug workflow)

1. Add the nav entry to `src/pug/partials/_nav-data.pug`.
2. Drop your page content (everything that would go inside `.container-fluid`) into `src/pug/partials/content/your-page.html`.
3. Create `src/pug/pages/your-page.pug`:

   ```pug
   extends ../layouts/_default

   block variables
     - var pageMeta = { title: 'Your page', description: 'Short description' }
     - var activePage = 'your-page.html'

   block content
     include ../partials/content/your-page.html
   ```

4. Run `npm run build:pug` (or leave `npm run dev` running).

## Customization Guide

### **Colors & Theming**
The template uses CSS custom properties for easy theming:

```css
:root {
  /* Primary Colors */
  --primary-color: #4272d7;
  --secondary-color: #6c757d;
  --success-color: #28a745;
  --warning-color: #ffc107;
  --danger-color: #dc3545;
  --info-color: #17a2b8;
  
  /* Background Colors */
  --body-bg: #f8f9fa;
  --card-bg: #ffffff;
  --sidebar-bg: #2c3e50;
  
  /* Text Colors */
  --text-primary: #212529;
  --text-secondary: #6c757d;
  --text-muted: #868e96;
}
```

### **Chart Customization**
Charts use Chart.js v4 configuration format:

```javascript
const chartConfig = {

### **Adding New Components**
The vanilla JavaScript utilities make it easy to add new components:

```javascript
// Using the custom vanilla-utils.js
const element = $('.my-selector');           // querySelector
const elements = $$('.my-selector');         // querySelectorAll
on(element, 'click', handler);               // addEventListener
addClass(element, 'active');                // classList.add
removeClass(element, 'active');             // classList.remove
toggleClass(element, 'active');             // classList.toggle
```

## Mobile Optimization

## Modern JavaScript Features

### **Vanilla JavaScript Utilities**
Replace jQuery with modern JavaScript patterns:

```javascript
// Old jQuery way
$('.element').addClass('active').on('click', handler);

// New vanilla way
const element = $('.element');
addClass(element, 'active');
on(element, 'click', handler);

// Modern ES6+ patterns
document.querySelectorAll('.elements').forEach(el => {
  el.addEventListener('click', (e) => {
    e.target.classList.toggle('active');
  });
});
```

### **Chart.js v4 Integration**
Modern chart configuration with improved performance:

```javascript
// Automatic chart initialization
document.addEventListener('DOMContentLoaded', () => {
  const charts = document.querySelectorAll('[data-chart]');
  charts.forEach(canvas => {
    const type = canvas.dataset.chart;
    const config = getChartConfig(type);
    new Chart(canvas, config);
  });
});
```
