Installation

Resources are available within the CdrButton package:

Name	Type	Description
@rei/cdr-button	Node module package	Import the component into your project
cdr-button.css	Style sheet	Component specific styles

To incorporate the required assets for a component, use the following steps:

1. Install using NPM

Install the CdrButton package using npm in your terminal:

Terminal

    npm i -s @rei/cdr-button

2. Import dependencies

main.js

// import your required css.
import "@rei/cdr-link/dist/cdr-button.css";

3. Add component to a template

In this example we’ll create a medium-sized primary button, which is the default.

local.vue

<template>
  <cdr-button
    type="button"
  >
    Add to cart
  </cdr-button>
</template>

<script>
import { CdrButton } from '@rei/cdr-button';
export default {
  ...
  components: {
     CdrButton  
  }
}
</script>

Usage

Size, responsive size, and full-width sizing props

The below example uses both the size and responsive-size props. This button’s size is small, but it will become a large button at the xs and sm breakpoints.

<template>
  <cdr-button
    size="small"
    :responsive-size="[‘large@xs’, ‘large@sm’]"
  >
    Add to cart
  </cdr-button>
</template>

Modifiers

Following variants are available to the cdr-button modifier attribute:

Value	Description
secondary	Sets the secondary style for the button

Click Actions

Use the on-click prop to attach custom actions and event handling.

<template>
  <cdr-button
    :on-click="greet"
  >
    Greet
  </cdr-button>
</template>

<script>
export default {
  ...
  methods: {
    greet() {
      console.log(‘Hello there’);
    }
  }
}
</script>

Composing with icons

CdrButton can be used with the icon component from the CdrIcon package.

Text and Icon

To scale Cedar icons appropriately, include the cdr-button__icon class with any icon component. The size prop scales both the icon and button.

In the below example, a Download button is rendered as a button with icon and text using cdr-icon and the icon sprite.

<template>
  <cdr-button>
    <cdr-icon
      slot="icon"
      class="cdr-button__icon"
      use="#download"
    />
    Download
  </cdr-button>
</template>

<script>
import { CdrButton } from '@rei/cdr-button';
import { CdrIcon } from '@rei/cdr-icon;
export default {
  ...
  components: {
     CdrButton,
     CdrIcon,  
  }
}
</script>

Icon Only

Use the following props to modify cdr-button:

• Default slot must be empty. If text is present in default slot, the text will render
• size prop is disable when icon-only prop is true
• For the SVG files:
  • If the fill color is dark, assign true to the on-dark prop
  • on-dark prop only works if icon-only prop is also true
• Add aria-label text to describe the button’s action when clicked or tapped

<template>
  <cdr-button
    :icon-only="true"
    :on-dark="true"
    aria-label="Complete this step"
  >
    <icon-check-lg
      slot="icon"
      class="cdr-button__icon" />
  </cdr-button>
</template>

CdrCloseButton & CdrPlayButton

The CdrButton package includes two specific icon-only variants. CdrCloseButton and CdrPlayButton include their respective icons and aria-label text for accessibility.

<template>
  <cdr-close-button />
</template>

<script>
import { CdrCloseButton } from '@rei/cdr-button';

export default {
  ...
  components: {
     CdrCloseButton  
  }
}
</script>

Accessibility

• Cdr-button renders as a button or anchor:
  • Select the semantically correct element, which will ensure that screen readers have correct instructions for how to interact with the component
  • Use cdr-link to make a button that looks like a link
  • Do not use div or input elements
• Do not add role=”button” to cdr-button
• Icon-only buttons require aria-label text since only the icon is visible
