Hyva Cms Component

Hyvä CMS Component Creator

Overview

This skill guides the interactive creation of custom Hyvä CMS components for Magento 2. It supports creating components in new or existing modules, with field presets for common patterns and automatic setup:upgrade execution.

Command execution: For commands that need to run inside the development environment (e.g., bin/magento), use the hyva-exec-shell-cmd skill to detect the environment and determine the appropriate command wrapper.

Workflow

Step 1: Module Selection

If not already specified in the prompt, ask the user where to create the component:

Option A: New Module

Ask for both values (do not assume defaults without asking):

1. Vendor name (e.g., Acme) - Required, no default. Do not suggest a Vendor name, prompt for user input.
2. Module name - Suggest CmsComponents as default so user can press Enter to accept

Then use the hyva-create-module skill with:

• dependencies: ["Hyva_CmsBase"]
• composer_require: {"hyva-themes/commerce-module-cms": "^1.0"}

Option B: Existing Module

• Request the module path (can be in app/code/, vendor/, or custom location)
• Verify the module has Hyva_CmsBase as a dependency in etc/module.xml. If not present, add it.
• Verify the module has hyva-themes/commerce-module-cms as a dependency in composer.json. If not present, add it.

Step 2: Component Details

Gather component information:

1. Component name (snake_case, e.g., feature_card)
2. Label (display name in editor, e.g., "Feature Card")
3. Category (Layout, Elements, Media, Content, or Other)
4. Icon - Automatically select an appropriate icon:

Step 4a: Identify icons already in use Use the hyva-cms-components-dump skill to dump all current CMS components. Extract all icon values from the output to build a list of icons already in use by existing components.

Step 4b: Find available lucide icons List the SVG files in vendor/hyva-themes/magento2-theme-module/src/view/base/web/svg/lucide/ to get the full set of available icons.

Step 4c: Select the best fitting icon From the available lucide icons that are NOT already in use by another component:

• Choose the icon whose name best matches the purpose/meaning of the new component
• Consider semantic meaning (e.g., shopping-cart.svg for cart-related, image.svg for image-related, layout-grid.svg for grid layouts)
• Format the selected icon as Hyva_Theme::svg/lucide/[icon-name].svg

If no suitable unused icon can be found, or if the lucide directory doesn't exist, leave the icon property unset.

Step 3: Field Selection

Offer field presets or custom field creation. See references/field-types.md "Field Presets" section for available presets (Basic Card, Image Card, CTA Block, Text Block, Feature Item, Testimonial, Accordion Item) or allow custom field definition.

Authoritative field types: prefer the project's live list when available — run bin/magento hyva:cms:list-fields (core + custom field types) via the hyva-exec-shell-cmd wrapper. Fall back to references/field-types.md only when the command is unavailable.

For custom fields, iterate through each field asking:

1. Field name (snake_case)
2. Field type (see references/field-types.md)
3. Label
4. Default value (optional)
5. Required? (yes/no) - Note: This will be added as attributes.required, NOT as a direct field property
6. Any additional attributes (these go in the attributes object)

Step 4: Variant Support

Ask if the component needs template variants:

• If yes: Gather variant names and labels (e.g., default, compact, wide). See references/variant-support.md for configuration details.
• If no: Use single template

Step 5: Generate Files

Create the required files:

For New Modules

The hyva-create-module skill creates the base module structure. Then add the CMS-specific directories:

app/code/[Vendor]/[Module]/
├── registration.php          # Created by hyva-create-module
├── composer.json             # Created by hyva-create-module
├── etc/
│   ├── module.xml            # Created by hyva-create-module
│   └── hyva_cms/
│       └── components.json   # Create this
└── view/
    └── frontend/
        └── templates/
            └── elements/
                └── [component-name].phtml (or [component-name]/ for variants)

For Existing Modules

Create or update:

• etc/hyva_cms/components.json (merge with existing if present)
• view/frontend/templates/elements/[component-name].phtml

Step 6: Run Setup

After creating files, run bin/magento setup:upgrade using the appropriate command wrapper detected by the hyva-exec-shell-cmd skill.

File Generation Details

components.json Structure

{
    "[component_name]": {
        "label": "[Label]",
        "category": "[Category]",
        "template": "[Vendor]_[Module]::elements/[component-name].phtml",
        "content": {
            // Generated fields
        },
        "design": {
            "includes": [
                "Hyva_CmsBase::etc/hyva_cms/default_design.json",
                "Hyva_CmsBase::etc/hyva_cms/default_design_typography.json"
            ]
        },
        "advanced": {
            "includes": [
                "Hyva_CmsBase::etc/hyva_cms/default_advanced.json"
            ]
        }
    }
}

Valid Component Properties

IMPORTANT: Only specific properties are allowed at the component level. See references/component-schema.md for the complete schema reference.

Key properties: label (required), category, template, icon, children, require_parent, content, design, advanced, disabled, custom_properties.

Invalid properties that will cause schema errors:

• hidden - Does not exist. Use require_parent: true for child-only components, or disabled: true
• Any property not listed in the schema reference

Children Configuration (CRITICAL)

IMPORTANT: children is a ROOT-LEVEL component property, NOT a field type within content, design, or advanced.

INCORRECT ❌:

{
    "my_component": {
        "content": {
            "items": {
                "type": "children",
                "label": "Items"
            }
        }
    }
}

CORRECT ✅:

{
    "my_component": {
        "label": "My Component",
        "children": {
            "config": {
                "accepts": ["child_component"],
                "max_children": 10
            }
        },
        "content": {
            "title": {
                "type": "text",
                "label": "Title"
            }
        }
    }
}

In templates, access children via $block->getData('children'), NOT via a custom field name.

Field Validation (CRITICAL)

IMPORTANT: Field validation attributes like required must be placed in the attributes object, NOT as direct field properties.

INCORRECT ❌:

{
    "title": {
        "type": "text",
        "label": "Title",
        "required": true
    }
}

CORRECT ✅:

{
    "title": {
        "type": "text",
        "label": "Title",
        "attributes": {
            "required": true
        }
    }
}

Other validation attributes that go in attributes:

• required (boolean)
• minlength / maxlength (string)
• min / max (for numbers)
• pattern (regex string)
• placeholder (string)
• comment (help text)
• Custom data attributes for validation messages

Child-Only Components

For components that should only be used as children of other components (like list items), use require_parent: true:

{
    "my_list_item": {
        "label": "My List Item",
        "category": "Elements",
        "require_parent": true,
        "template": false,
        "content": {
            "title": {"type": "text", "label": "Title"}
        }
    },
    "my_list": {
        "label": "My List",
