eBayUI Core

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

Requirements

Node.js
Marko (v4+)
eBay Skin (v16+)

Note: eBayUI Core components utilize Marko flags and, therefore, require <lasso-page/> to be added to any page which will have core components.

Note: @ebay/skin/global and @ebay/skin/marketsans are required to be loaded by your app for all modules to load correctly.

Note: In order for spread attributes to work properly, marko@4.18.22 at least is required

Browser Policy

All components are developed and tested cross-browser using BrowserStack, in accordance with our official eBay Browser Policy.

Accessibility (A11Y)

We take accessibility very seriously. Very seriously indeed. Therefore, all components are built in accordance to the <a href="https://ebay.gitbooks.io/mindpatterns/content/">eBay MIND Patterns</a>. These patterns, in turn, build on from the specifications provided by the <a href="https://w3c.github.io/aria-practices/">WAI-ARIA Authoring Practices</a>.

Components are built in a layered, progressively enhanced fashion, utilizing the following resources:

<a href="https://github.com/ianmcburnie/bones">Bones (HTML)</a>
<a href="https://github.com/eBay/skin">eBay Skin (CSS)</a>
<a href="https://github.com/makeup-js">MakeupJS (JavaScript)</a>

Each layer does its bit to enforce and enhance accessibility. We consider this level of support to be one of our chief selling points, and we hope you do too!

Components

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:

npm add @ebay/ebayui-core

Upgrading to the latest versions

See the upgrade guide for more information

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

Attributes

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

template.marko

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

Passing new attributes to an ebayui component will always reset it's internal state. If you want to persist this state yourself, events are exposed which allow you to synchronize the state into your own components, for example:

class {
    onCreate() {
        this.state = {
            dialogIsOpen: false
        }
    }

    handleDialogClose() {
        this.state.dialogIsOpen = false;
    }

    handleDialogOpen() {
        this.state.dialogIsOpen = true;
    }
}

<ebay-lightbox-dialog
    open=state.dialogIsOpen
    on-open('handleDialogOpen')
    on-close('handleDialogClose')>
    ...
</ebay-lightbox-dialog>

Pass-Through Attributes

HTML attributes can be used on any component, and they will be passed through to the most prominent tag of the component. The most prominent tag is usually the root or form control, but individual components will note if it varies for specific cases.

Example of static usage:

<ebay-button id="my-button"/>

For using pass-through attributes dynamically, they should be sent through the html-attributes attribute:

$ const myAttributes = { id: 'my-button' };
<ebay-button html-attributes=myAttributes/>

Static and dynamic pass-through attributes can be used simultaneously (html-attributes takes precedence in conflicts):

$ const myAttributes = { id: 'my-button' };
<ebay-button html-attributes=myAttributes type="submit"/>

Events

Events can also be handled using Marko syntax:

template.marko

<ebay-menu text="Sort" type="radio" on-change("onMenuChange")>
    <@item>Price</@item>
    <@item>Time</@item>
    <@item>Distance</@item>
</ebay-menu>
