šŸ“¦ Installation

To install this component, run:
yarn add @bliss-design-system/button

šŸŽ Usage

To use this component, you'll need to register the component to the window's Custom Elements Registry. In order to achieve that, you'll want to call this function within your application's client-facing entry file:
import { blissRegisterButton } from '@bliss-design-system/button';

blissRegisterButton(); // Registers <bliss-button>

That will make the component available in your application and you can use it like this:
<!-- renders a primary button with a default theme in medium size -->
<bliss-button>I am button</bliss-button>

To use the button with an icon, you'll need to have the <bliss-icon> component and the Iconsets registered to your application. Both are peer dependencies of this component, and you won't be able to see the icon without them.
<bliss-button icon="trash">

To use the button with a loading spinner, you'll need to have the <bliss-loading> component registered to your application. It is a peer dependency of this component, and you won't be able to see the loading state without it.
<bliss-button loading>
  Doing things

There are multiple attributes you can add to the button to leverage different needs, e.g. for a secondary, full width, critical button:
<bliss-button variant="secondary" theme="critical" full-width>
  Very wide and important button

In addition to the examples above, the you can also render an <a> with button styling (including the button attributes defined below), by providing a href:
<bliss-button href="www.example.com">
  I'm a link!


The button accepts the following attributes:
| Attribute | Type | Description | Default | Required | Options | | --------------- |:--------------:| :-------------------------:|:-------:|:--------:|:-------:| | size | string | defines the button size | medium | false | small, medium | | type | string | defines the button type | button | false | button, submit, reset | | theme | string | button theme | default | false | default, neutral, critical | | variant | string | button variant | primary | false | primary, secondary, ghost | | disabled | boolean | disable the button | false | false | - | | loading | boolean | display the loading spinner | false | false | - | | icon-only | boolean | display an icon only | false | false | - | | icon-trailing | boolean | display icon after the label | false | false | - | | full-width | boolean | make the button full width of its container | false | false | - |
For a link styled like a button, you can use the following attributes in addition to the ones in the table above:
| Attribute | Type | Description | Default | Required | Options | | --------------- |:--------------:| :-------------------------:|:-------:|:--------:|:-------:| | href | string | URL | '' | false | - | | target | string | where to display the linked URL | '' | false | _blank, _self, _top, _parent | | rel | string | relationship of the linked URL | '' | false | - | | download | string | download instead of navigate | '' | false | - |


The button comes with three themes to choose from, but we recognise that there might be instances where that might not be enough. If you need to change the color of the component, or of an icon or loading spinner within the component, you can access the styles with the ::part pseudo element. The implementation looks like this:
bliss-button::part(button) {
  color: green

>āš ļø Please note, Bliss can't support all of the variations that might come up over time, so it will be your full responsibility to maintain any changes that you make to the component that don't follow the existing API.


The <bliss-button> handles labelling for you in every state.
The only requirement is that you always pass in text content, even if you are using an icon-only variation of the button, because that is what the button relies on to populate its aria-label.
The colour contrast is handled out of the box for each variant and each theme.

You don't need to move into the package's directory to run storybook, tests or anything else. All of those commands exist in the root of the component toolkit, so while you can work on the component within its specific folder, you don't need to move through directories to run anything.
