@ebay/ebayui-core

eBayUI Core

Collection of core eBay components; considered to be the building blocks for all composite structures, pages & apps.

The eBayUI components are Marko custom tags that follow the core principles of HTML. For example:

• Input attributes can only be of type String or Boolean
• State can be manipulated directly from the DOM node
• Events are fired through both Marko and the DOM

For more information, please read Building a UI Component in 2017 and Beyond.

Requirements

• Node.js
• Marko (v3+)
• eBay Skin (v3+)

NOTE: Marko v3 also requires Marko Widgets.

Components

• ebay-breadcrumb
• ebay-button
• ebay-menu
• ebay-select
• ebay-notice

Getting Started

The eBayUI core components are available as the @ebay/ebayui-core package on NPM.

Use npm or yarn to add the package dependency to your project:

yarn add @ebay/ebayui-core

Custom Tags

Once the package dependency is added, the eBay customs tags are now available for use in your Marko templates. For example, to use an ebay-menu component:

template.marko

<ebay-menu label="Sort" type="radio">
    <ebay-menu-item>Price</ebay-menu-item>
    <ebay-menu-item>Time</ebay-menu-item>
    <ebay-menu-item>Distance</ebay-menu-item>
</ebay-menu>

On Marko v3, remember to include the component's resources in your browser.json file.

browser.json

{
    "dependencies": [
        "@ebay/ebayui-core/ebay-menu"
    ]
}

Attributes

Attributes provide initial state for a component. We can see that the menu has label and type attributes:

template.marko

<ebay-menu label="Sort" type="radio">
    <ebay-menu-item>Price</ebay-menu-item>
    <ebay-menu-item>Time</ebay-menu-item>
    <ebay-menu-item>Distance</ebay-menu-item>
</ebay-menu>

Some attributes are stateful and can be updated via the DOM. The label attribute, for example:

var menu = document.querySelector('.menu');
menu.label = 'Sortieren';

NOTE: Undocumented attributes are assumed to be HTML and will be applied to the root element of the custom tag.

Events

Events can be handled via the DOM. For example, the menu emits a menu-change event:

menu.addEventListener('menu-change', onMenuChange);

Events can also be handled using Marko syntax:

template.marko

<ebay-menu label="Sort" type="radio" w-onchange("onMenuChange")>
    <ebay-menu-item>Price</ebay-menu-item>
    <ebay-menu-item>Time</ebay-menu-item>
    <ebay-menu-item>Distance</ebay-menu-item>
</ebay-menu>

Note: when using DOM events, you should also handle event destruction and delegation as needed.

Browser Policy

All components support browsers from the official Tier 1 and Tier 2 of the eBay Browser Policy. This list is defined in the browserslist section of our package.json, where it is also accessible to internal tooling.
