# Page Designer Skill

This skill guides you through creating custom Page Designer page types and component types for Salesforce B2C Commerce.

## Overview

Page Designer allows merchants to create and manage content pages through a visual editor. Developers create:

1. **Page Types** - Define page structures with regions
2. **Component Types** - Reusable content blocks with configurable attributes

## File Structure

Page Designer files are in the cartridge's `experience` directory:

```
/my-cartridge
    /cartridge
        /experience
            /pages
                homepage.json           # Page type meta definition
                homepage.js             # Page type script
            /components
                banner.json             # Component type meta definition
                banner.js               # Component type script
        /templates
            /default
                /experience
                    /pages
                        homepage.isml   # Page template
                    /components
                        banner.isml     # Component template
```

**Naming:** The `.json` and `.js` files must have matching names. Use only **alphanumeric** or **underscore** in file names and in any subdirectory names under `experience/pages` or `experience/components`.

**Component types in subfolders:** You can put component meta and script in a subdirectory (e.g. `experience/components/assets/`). The **component type ID** is then the path with dots: `assets.hero_image_block`. The template path under `templates/default/` must mirror that path (e.g. `templates/default/experience/components/assets/hero_image_block.isml`), and the script must call `Template('experience/components/assets/hero_image_block')` so the path matches. Stored ID is `component.{component_type_id}`; total length must not exceed 256 characters.

## Page Types

### Meta Definition (pages/homepage.json)

```json
{
    "name": "Home Page",
    "description": "Landing page with hero and content regions",
    "region_definitions": [
        {
            "id": "hero",
            "name": "Hero Section",
            "max_components": 1
        },
        {
            "id": "content",
            "name": "Main Content"
        },
        {
            "id": "footer",
            "name": "Footer Section",
            "component_type_exclusions": [
                { "type_id": "video" }
            ]
        }
    ]
}
```

### Page Script (pages/homepage.js)

```javascript
'use strict';

var Template = require('dw/util/Template');
var HashMap = require('dw/util/HashMap');

module.exports.render = function (context) {
    var model = new HashMap();
    var page = context.page;

    model.put('page', page);

    return new Template('experience/pages/homepage').render(model).text;
};
```

### Page Template (templates/experience/pages/homepage.isml)

```html
<isdecorate template="common/layout/page">
    <isscript>
        var PageRenderHelper = require('*/cartridge/experience/utilities/PageRenderHelper');
    </isscript>

    <div class="homepage">
        <div class="hero-region">
            <isprint value="${PageRenderHelper.renderRegion(pdict.page.getRegion('hero'))}" encoding="off"/>
        </div>

        <div class="content-region">
            <isprint value="${PageRenderHelper.renderRegion(pdict.page.getRegion('content'))}" encoding="off"/>
        </div>

        <div class="footer-region">
            <isprint value="${PageRenderHelper.renderRegion(pdict.page.getRegion('footer'))}" encoding="off"/>
        </div>
    </div>
</isdecorate>
```

## Component Types

### Meta Definition (components/banner.json)

```json
{
    "name": "Banner",
    "description": "Promotional banner with image and CTA",
    "group": "content",
    "region_definitions": [],
    "attribute_definition_groups": [
        {
            "id": "image",
            "name": "Image Settings",
            "attribute_definitions": [
                {
                    "id": "image",
                    "name": "Banner Image",
                    "type": "image",
                    "required": true
                },
                {
                    "id": "alt",
                    "name": "Alt Text",
                    "type": "string",
                    "required": true
                }
            ]
        },
        {
            "id": "content",
            "name": "Content",
            "attribute_definitions": [
                {
                    "id": "headline",
                    "name": "Headline",
                    "type": "string",
                    "required": true
                },
                {
                    "id": "body",
                    "name": "Body Text",
                    "type": "markup"
                },
                {
                    "id": "ctaUrl",
                    "name": "CTA Link",
                    "type": "url"
                },
                {
                    "id": "ctaText",
                    "name": "CTA Button Text",
                    "type": "string"
                }
            ]
        },
        {
            "id": "layout",
            "name": "Layout Options",
            "attribute_definitions": [
                {
                    "id": "alignment",
                    "name": "Text Alignment",
                    "type": "enum",
                    "values": ["left", "center", "right"],
                    "default_value": "center"
                },
                {
                    "id": "fullWidth",
                    "name": "Full Width",
                    "type": "boolean",
                    "default_value": false
                }
            ]
        }
    ]
}
```

**Component meta:** Always include `region_definitions`. Use `[]` when the component has no nested regions (no slots for other components).

### Component Script (components/banner.js)

```javascript
'use strict';

var Template = require('dw/util/Template');
var HashMap = require('dw/util/HashMap');
var URLUtils = require('dw/web/URLUtils');

module.exports.render = function (context) {
    var model = new HashMap();
    var content = context.content;

    // Access merchant-configured attributes
    model.put('image', content.image);        // Image object
    model.put('alt', content.alt);            // String
    model.put('headline', content.headline);  // String
    model.put('body', content.body);          // Markup string
    model.put('ctaUrl', content.ctaUrl);      // URL object
    model.put('ctaText', content.ctaText);    // String
    model.put('alignment', content.alignment || 'center');
    model.put('fullWidth', content.fullWidth);

    return new Template('experience/components/banner').render(model).text;
};
```

**Template path:** The path passed to `Template(...)` must match the template path under `templates/default/`. If the component lives in a subfolder (e.g. `experience/components/assets/hero_image_block`), use `Template('experience/components/assets/hero_image_block')` and place the ISML at `templates/default/experience/components/assets/hero_image_block.isml`.

**Handling colors (string or color picker object):** If an attribute can be a hex string or a color picker object `{ color: "#hex" }`, use a small helper so the script works with both:

```javascript
function getColor(colorAttr) {
    if (!colorAttr) return '';
    if (typeof colorAttr === 'string' && colorAttr.trim()) return colorAttr.trim();
    if (colorAttr.color) return colorAttr.color;
    return '';
}
```

### Component Template (templates/experience/components/banner.isml)

```html
<div class="banner ${pdict.fullWidth ? 'banner--full-width' : ''}"
     style="text-align: ${pdict.alignment}">
    <isif condition="${pdict.image}">
        <img src="${pdict.image.file.absURL}"
             alt="${pdict.alt}"
             class="banner__image"/>
    </isif>

    <div class="banner__content">
        <h2 class="banner__headlin
