You write `.phtml` templates using Alpine.js (not KnockoutJS), Tailwind CSS (not LESS), and View Models (not Blocks). You always use `$escaper->escapeHtml()` for output, fetch data via GraphQL or PHP View Models, and never use RequireJS or jQuery. --- ## Hyvä vs Luma — Key Differences | Aspect | Luma (Legacy) | Hyvä | |--------|--------------|------| | JavaScript | RequireJS + KnockoutJS + jQuery | Alpine.js | | CSS | LESS compilation | Tailwind CSS | | Bundle size | ~300KB+ JS | ~30KB JS | | Data fetching | Section data / knockout | GraphQL + PHP View Models | | Template format | `.phtml` + KO `` | `.phtml` with Alpine.js attributes | | State management | KO observables | Alpine.js `x-data` | **Never use** in Hyvä: `require()`, `define()`, `ko.observable()`, jQuery, LESS, `data-mage-init`, `data-bind`. --- ## Theme Structure ``` app/design/frontend/Vendor/hyva-child/ ├── registration.php ├── theme.xml # Parent: Hyva/default ├── composer.json ├── web/ │ └── tailwind/ │ ├── tailwind-source.css # @tailwind directives + @layer components │ └── tailwind.config.js # Content paths + theme extensions └── Magento_Theme/ └── templates/ └── html/ ├── header.phtml └── footer.phtml ``` **theme.xml**: ```xml My Hyvä Child Theme Hyva/default ``` --- ## Tailwind CSS ### Build Commands ```bash cd app/design/frontend/Vendor/hyva-child/web/tailwind npm install npm run watch # Development npm run build-prod # Production ``` ### tailwind.config.js ```javascript const { theme } = require('tailwindcss/defaultTheme'); const colors = require('tailwindcss/colors'); module.exports = { content: [ '../../**/*.phtml', '../../../Hyva/default/**/*.phtml', '../../../../code/**/*.phtml', ], theme: { extend: { colors: { primary: colors.blue, secondary: colors.gray, accent: colors.amber, }, fontFamily: { sans: ['Inter', ...theme.fontFamily.sans], }, }, }, plugins: [ require('@tailwindcss/forms'), require('@tailwindcss/typography'), ], }; ``` ### tailwind-source.css ```css @tailwind base; @tailwind components; @tailwind utilities; @layer components { .btn-primary { @apply px-4 py-2 bg-primary-600 text-white rounded-lg hover:bg-primary-700 transition-colors duration-200 font-medium; } .btn-secondary { @apply px-4 py-2 bg-white text-primary-600 border border-primary-600 rounded-lg hover:bg-primary-50 transition-colors duration-200; } .card { @apply bg-white rounded-lg shadow-md p-6; } .form-input { @apply mt-1 block w-full border-gray-300 rounded-md shadow-sm focus:ring-primary-500 focus:border-primary-500; } } ``` --- ## View Models (Preferred over Block Classes) ### ViewModel — `ViewModel/ProductData.php` ```php productRepository->get($sku); } catch (NoSuchEntityException) { return null; } } public function formatPrice(float $price): string { return '$' . number_format($price, 2); } } ``` ### Layout XML (wiring View Model) ```xml Vendor\Module\ViewModel\ProductData ``` ### Template consuming View Model ```php getData('view_model'); $product = $viewModel->getProductBySku('SKU-001'); ?> escapeHtml($product->getName()) ?> escapeHtml($viewModel->formatPrice((float)$product->getPrice())) ?> ``` --- ## Alpine.js Patterns ### Basic Component ```html function initProductGallery() { return { images: getGalleryImagesJson() ?>, activeIndex: 0, get activeImage() { return this.images[this.activeIndex]?.full || ''; }, get activeAlt() { return this.images[this.activeIndex]?.alt || ''; }, setActive(index) { this.activeIndex = index; }, init() { /* initialization logic */ } } } ``` ### Add to Cart ```html Add to Cart Adding... function initAddToCart() { return { qty: 1, isLoading: false, message: '', async addToCart() { this.isLoading = true; this.message = ''; try { await fetch('/rest/V1/carts/mine/items', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ cartItem: { sku: escapeJs($block->getProduct()->getSku()) ?>, qty: this.qty } }) }); this.message = 'Added to cart!'; window.dispatchEvent(new CustomEvent('reload-customer-section-data')); } catch { this.message = 'Error adding to cart. Please try again.'; } this.isLoading = false; } } } ``` ### Global Alpine Store (Shared State) ```html document.addEventListener('alpine:init', () => { Alpine.store('cart', { count: 0, async refresh() { const res = await fetch('/customer/section/load/?sections=cart'); const data = await res.json(); this.count = data.cart?.summary_count || 0; } }); }); ``` ### GraphQL Data Fetching **Public query (no auth):** ```html function initProductList() { return { products: [], async fetchProducts() { const res = await fetch('/graphql', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ query: `{ products(filter: { category_id: { eq: "10" } }, pageSize: 12) { items { sku name small_image { url } price_range { minimum_price { final_price { value currency } } } } } }`}) }); const data = await res.json(); this.products = data.data.products.items; } } } ``` **Customer-authenticated query (wishlist, orders, account):** For customer-specific data, pass the customer token via `Authorization: Bearer` header. In Hyvä, retrieve it from the customer section or store it in Alpine state after login. ```html function initWishlist() { return { items: [], customerToken: window.authorizationToken || '', // set by Hyvä customer section async fetchWishlist() { const res = await fetch('/graphql', { method: 'POST', headers: { 'Content-Type': 'application/json', 'Authorization': `Bearer ${this.customerToken}` }, body: JSON.stringify({ query: `{ wishlist { items_v2 { items { id product { name sku small_image { url } } } } } }`}) }); const data = await res.json(); this.items = data.data?.wishlist?.items_v2?.items || []; } } } ``` --- ## Required Configuration (Disable Luma Incompatibilities) ```bash # Disable JS bundling and minification (Tailwind handles CSS) bin/magento config:set dev/js/enable_js_bundling 0 bin/magento config:set dev/js/minify_files 0 bin/magento config:set dev/css/minify_files 0 # Enable required GraphQL modules bin/magento module:enable \ Magento_CatalogGraphQl \ Magento_QuoteGraphQl \ Magento_CustomerGraphQl \ Magento_UrlRewriteGraphQl bin/magento setup:upgrade bin/magento cache:flush ``` --- ## Hyvä Best Practices | Practice | Description | |----------|-------------| | View Models for data | Prefer over Block classes — cleaner separation | | Alpine stores for shared state | Cart count, customer session, wishlist | | Tailwind utilities | Prefer `class="..."` over custom CSS files | | GraphQL for dynamic data | Use for product lists, cart, search | | `$escaper->escapeHtml()` | Always escape user/DB data in templates | | `/* @noEscape */` comment | Only for pre-validated JSON (e.g. gallery JSON) | | SVG icons | Use Heroicons (included in Hyvä) over icon fonts | | Child themes only | Never modify Hyva/default directly | | Purge paths in config | Keep `tailwind.config.js` content paths accurate | --- ## Compatibility Modules Third-party Luma modules need compatibility modules to work in Hyvä. Check: - Hyvä Module Tracker: `https://gitlab.hyva.io/hyva-public/module-tracker` ```json // hyva-themes.json — register custom module for Hyvä event system { "Vendor_Module": { "src": "app/code/Vendor/Module" } } ``` --- ## Instructions for LLM - Never use `require()`, `define()`, jQuery, KnockoutJS, or LESS in Hyvä templates - All dynamic JS logic goes in inline `` with Alpine.js `x-data` functions - Always use `$escaper->escapeHtml()` — use `/* @noEscape */` only for known-safe JSON - Data from PHP to Alpine: serialize with `json_encode()` and output with `/* @noEscape */` - Tailwind classes are purged based on content paths — if a class doesn't appear, add the path to `tailwind.config.js` - After Tailwind changes: `npm run build-prod` in the theme's tailwind directory - After PHP/layout changes: `bin/magento cache:clean` (+ static content deploy in production) - Hyvä uses GraphQL heavily — if you're loading dynamic data, prefer GraphQL over AJAX REST calls ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [furan917](https://github.com/furan917) - **Source:** [furan917/magento-ai-toolkit](https://github.com/furan917/magento-ai-toolkit) - **License:** MPL-2.0 Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-furan917-magento-ai-toolkit-magento-hyva - Seller: https://agentstack.voostack.com/s/furan917 - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
