# Adritian Hugo Theme - AI Coding Instructions
## Project Overview
This is a **Hugo theme** for personal websites/portfolios, not a standalone site (although a example site is provided, to demonstrate the usage of the theme itself). The theme provides layouts, styling, and functionality that users import via Hugo modules or as a git submodule.
**Technology Stack:**
- **Static Site Generator:** Hugo (v0.136+ extended version required)
- **CSS Framework:** Bootstrap 5 (v5.3.8)
- **CSS Preprocessor:** SCSS/Sass
- **JavaScript Libraries:** Fuse.js (search), DOMPurify (XSS protection)
- **Testing:** Playwright (E2E tests)
- **Package Manager:** npm
- **Templating:** Hugo Templates (Go templates)
- **Build Tools:** Hugo's built-in asset pipeline, PostCSS, Autoprefixer
## Project Architecture
This is a **Hugo theme** for personal websites/portfolios, not a standalone site. The theme provides layouts, styling, and functionality that users import via Hugo modules or as a git submodule.
The theme provides a example site (`exampleSite/`) that demonstrates all features and serves as a starting point for users. It is also used for the integration tests.
**Key Structure:**
- `layouts/` - Hugo templates (partials, shortcodes, content types)
- `assets/scss/` - Bootstrap 5-based styling with theme customizations
- `exampleSite/` - Demo content that gets distributed to users via `adritian-theme-helper` and serves as a github template repository
- `archetypes/` - Content templates for different content types
- `i18n/` - Multilingual translations (en/es/fr)
## Content Architecture & Custom Types
The theme implements **5 custom content types** with specific frontmatter:
1. **Experience** (`content/experience/`) - Job history with `jobTitle`, `company`, `location`, `duration`
2. **Skills** (`content/skills/`) - Technical skills with progress bars and categories
3. **Blog** (`content/blog/`) - Posts with sidebar/default layouts
4. **Client-work** (`content/client-work/`) - Portfolio pieces
5. **Testimonial** (`content/testimonial/`) - User testimonials
**Critical:** Each content type has a corresponding archetype in `archetypes/` and layout in `layouts/`. Always maintain this trio when adding new types.
## Development Workflows
### Local Development
```bash
# Install dependencies
npm install # Installs Bootstrap + theme-helper
# Theme development (testing with exampleSite)
npm run serve
```
### Testing
```bash
npm test # Full test suite
npm run test:e2e # Playwright E2E tests
npm run test:e2e:no-menus # Tests without navigation (for menu-less configs)
```
**Test Coverage:** E2E tests validate theme switching, language switching, content rendering, search functionality, and HTML validation across all major features.
### Performance Optimization
```bash
npm run build:performance # Optimized build with critical CSS
node scripts/optimize-performance.js # Performance analysis
```
## Styling System
**SCSS Architecture:** Modular approach extending Bootstrap 5
- `assets/scss/adritian.scss` - Main entry point importing all partials
- `assets/scss/_variables.scss` - Theme color/sizing variables
- Individual component files: `_navbar.scss`, `_blog.scss`, `_experience.scss`, etc.
**Theme Colors:** Uses CSS custom properties with `$base-color` as primary. Dark/light themes switch via CSS variables, not separate stylesheets.
## Multilingual (i18n) Implementation
**Translation Strategy:**
- Static strings: `i18n/*.yaml` files (navigation, UI elements)
- Content: Hugo's file-based translation (`content/en/`, `content/es/`, etc.)
- **Post-v1.7.0:** Prefers shortcode-based content over i18n strings for flexibility
## Shortcode System
**Primary Content Method:** Pages built with shortcodes rather than traditional Hugo sections.
Key shortcodes in `layouts/shortcodes/`:
- `experience-section` - Displays limited experience list (controlled by `homepageExperienceCount`)
- `experience-list` - Print-friendly experience list
- `contact-section` - Formspree integration
- `showcase-section` - Portfolio display
- `about-section`, `text-section` - Content blocks
**Pattern:** Most homepage sections use shortcodes for maximum customization flexibility.
## Module Distribution Model
**Critical Understanding:** This theme is distributed via:
1. **Hugo Module** (recommended) - `hugo mod get github.com/zetxek/adritian-free-hugo-theme`
2. **Theme Helper Package** - `@zetxek/adritian-theme-helper` downloads demo content
3. **Git Submodule** (legacy) - Direct theme inclusion
**Bootstrap Process:**
```bash
hugo mod get -u github.com/zetxek/adritian-free-hugo-theme
hugo mod npm pack
npm install # Installs Bootstrap + theme-helper
./node_modules/@zetxek/adritian-theme-helper/dist/scripts/download-content.js
```
## Configuration Patterns
**Hugo Config (`hugo.toml`):**
- Performance optimizations: `[minify]`, `[imaging]`, `[markup]` sections
- Custom output formats for content types (footer content excluded from HTML generation)
- Module imports section for theme loading
**Package.json Scripts:**
- `serve` - Development with exampleSite
- `build` - Production build with minification
- Separate test commands for different scenarios
## Key Integration Points
**Search:** Powered by Fuse.js with JSON index generation
**Contact Forms:** Formspree integration via shortcode
**Analytics:** Vercel Analytics support built-in
**Performance:** Critical CSS generation, image optimization, minification
## Common Development Pitfalls
1. **Missing Dependencies:** Theme requires Bootstrap via npm - users often miss `npm install` step
2. **Content Structure:** Custom content types require specific frontmatter fields - validate against archetypes
3. **Translation Scope:** Post-v1.7.0 prefers shortcode content over i18n strings
4. **Module vs Submodule:** Most issues stem from incorrect installation method
## Testing Philosophy
E2E tests validate real user workflows rather than individual components. Tests include theme switching, language switching, navigation, search, and content rendering across different configurations (with/without menus).
When modifying layouts or adding features, ensure corresponding E2E tests exist in `tests/e2e/`.
## Coding Standards and Conventions
### HTML/Hugo Templates
- Use semantic HTML5 elements for proper document structure
- Follow Hugo's template naming conventions (lowercase with hyphens)
- Partial templates should be in `layouts/partials/`
- Shortcodes should be in `layouts/shortcodes/`
- Use Hugo's built-in functions when available (e.g., `absURL`, `relURL`)
### SCSS/CSS
- Follow Bootstrap 5 conventions and utility classes where possible
- Use BEM naming methodology for custom components when needed
- Prefix custom variables with theme-specific identifiers
- Keep files modular - one component per file
- Use CSS custom properties for themeable values
- File naming: lowercase with underscores (e.g., `_navbar.scss`, `_blog.scss`)
### JavaScript
- Use vanilla JavaScript (no jQuery)
- Prefer modern ES6+ syntax
- Keep JavaScript minimal - theme is primarily CSS-driven
- Use DOMPurify for any user-generated content sanitization
- Ensure all JavaScript is progressively enhanced (works without JS when possible)
### Content and Configuration
- YAML frontmatter for content files
- TOML for Hugo configuration files
- Follow existing frontmatter patterns for each content type
- Use descriptive, human-readable keys
### File Naming Conventions
- Templates: lowercase with hyphens (e.g., `single.html`, `list.html`)
- SCSS files: lowercase with underscores, prefixed with `_` for partials
- Content files: lowercase with hyphens (e.g., `my-blog-post.md`)
- Archetypes: match content type name (e.g., `blog.md`, `experience.md`)
## Web Accessibility Requirements
**This theme prioritizes accessibility (WCAG 2.1 AA compliance):**
- All interactive elements must be keyboard accessible
- Proper ARIA labels and roles for non-semantic elements
- Color contrast ratios must meet WCAG AA standards (4.5:1 for normal text, 3:1 for large text)
- Images must have descriptive `alt` attributes
- Forms must have associated labels
- Focus indicators must be visible and clear
- Dark/light theme switching must maintain accessibility standards in both modes
- Skip navigation links for keyboard users
- Semantic HTML structure (proper heading hierarchy, landmarks, etc.)
- Test changes with screen readers when modifying navigation or interactive elements
## Security Best Practices
- Never commit secrets, API keys, or sensitive data
- Use DOMPurify for sanitizing any user-generated or external content
- Validate and sanitize all user inputs in contact forms
- Follow Hugo's security best practices for template rendering
- Keep dependencies updated to patch security vulnerabilities
- Use Hugo's built-in `safeHTML`, `safeCSS`, `safeJS` functions appropriately
## Files and Directories to Ignore
Copilot should **ignore** or be cautious with:
- `node_modules/` - Third-party dependencies
- `public/` - Hugo build output (generated files)
- `resources/` - Hugo's asset cache
- `.hugo_build.lock` - Hugo build lock file
- `package-lock.json` - npm lock file (only update via npm commands)
- `.git/` - Version control directory
- `exampleSite/public/` - Example site build output
- `exampleSite/resources/` - Example site cache
- `.DS_Store` - macOS system files
