# Icon
|
||
|
||
The `Icon` component in conjunction with `ICON_NAMES` can be used for all icons in the extension
|
||
|
||
<Canvas>
|
||
<Story id="components-componentlibrary-icon--default-story" />
|
||
</Canvas>
|
||
|
||
## Props
|
||
|
||
The `Icon` accepts all props below as well as all [Box](/docs/components-ui-box--default-story#props) component props
|
||
|
||
<ArgsTable of={Icon} />
|
||
|
||
### Name
|
||
|
||
Use the `name` prop and the `ICON_NAMES` object to change the icon.
|
||
|
||
Use the [IconSearch](/story/components-componentlibrary-icon--default-story) story to find the icon you want to use.
|
||
|
||
<Canvas>
|
||
<Story id="components-componentlibrary-icon--name" />
|
||
</Canvas>
|
||
|
||
```jsx
|
||
import { Icon, ICON_NAMES } from '../../component-library';
|
||
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} />
|
||
<Icon name={ICON_NAMES.BANK} />
|
||
<Icon name={ICON_NAMES.CALCULATOR} />
|
||
<Icon name={ICON_NAMES.COIN} />
|
||
// etc...
|
||
```
|
||
|
||
### Size
|
||
|
||
Use the `size` prop and the `Size` object from `./ui/helpers/constants/design-system.js` to change the size of `Icon`. Defaults to `Size.SM`
|
||
|
||
Possible sizes include:
|
||
|
||
- `Size.XS` 12px
|
||
- `Size.SM` 16px
|
||
- `Size.MD` 20px
|
||
- `Size.LG` 24px
|
||
- `Size.XL` 32px
|
||
- `Size.inherit` inherits the font-size from parent element. This is useful for inline icons in text.
|
||
|
||
<Canvas>
|
||
<Story id="components-componentlibrary-icon--size-story" />
|
||
</Canvas>
|
||
|
||
```jsx
|
||
import { Size，TextVariant } from '../../../helpers/constants/design-system';
|
||
import { Icon, ICON_NAMES } from '../../component-library';
|
||
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} size={Size.XS} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} size={Size.SM} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} size={Size.MD} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} size={Size.LG} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} size={Size.XL} />
|
||
<Text as="p" variant={TextVariant.bodySm}>
|
||
<Icon size={Size.inherit} /> inherits the
|
||
font-size of the parent element.
|
||
</Text>
|
||
```
|
||
|
||
### Color
|
||
|
||
Use the `color` prop and the `Color` object from `./ui/helpers/constants/design-system.js` to change the color of `Icon`. Defaults to `Color.inherit` which will use the text color of the parent element. This is useful for inline icons.
|
||
|
||
<Canvas>
|
||
<Story id="components-componentlibrary-icon--color-story" />
|
||
</Canvas>
|
||
|
||
```jsx
|
||
import { IconColor } from '../../../helpers/constants/design-system';
|
||
import { Icon, ICON_NAMES } from '../../component-library';
|
||
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.inherit} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.iconDefault} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.iconAlternative} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.iconMuted} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.overlayInverse} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.primaryDefault} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.primaryInverse} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.errorDefault} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.errorInverse} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.successDefault} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.successInverse} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.warningDefault} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.warningInverse} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.infoDefault} />
|
||
<Icon name={ICON_NAMES.ADD_SQUARE} color={IconColor.infoInverse} />
|
||
```
|
||
|
||
### Layout & Spacing
|
||
|
||
The `Icon` component accepts all [Box](/docs/components-ui-box--default-story#props) component props including `marginTop`, `marginRight`, ` marginBottom`, `marginLeft` which you can use directly to adjust the space between icons and other components like `Text`
|
||
|
||

### Adding a new icon
|
||
|
||
To add a new icon the only thing you need to do is add the icon svg file to `app/images/icons`. To ensure that the icon is added correctly follow these steps:
|
||
|
||
#### Step 1.
|
||
|
||
Optimize the svg using [Fontastic](https://fontastic.me/). This will remove any unnecessary code from the svg. Your svg should only contain a single path.
|
||
|
||
Example of a correctly optimized svg:
|
||
|
||
```
|
||
<svg xmlns="http://www.w3.org/2000/svg" id="icon-add-square-filled" viewBox="0 0 512 512">
|
||
<path d="m337 51l-171 0c-75 0-119 45-119 119l0 172c0 74 44 119 119 119l171 0c75 0 119-45 119-119l0-172c1-74-44-119-119-119z m-3 220l-67 0 0 67c0 8-7 15-15 15-9 0-16-7-16-15l0-67-66 0c-9 0-16-7-16-15 0-8 7-15 16-15l66 0 0-67c0-8 7-15 16-15 8 0 15 7 15 15l0 67 67 0c8 0 15 7 15 15 0 8-7 15-15 15z"/>
|
||
</svg>
|
||
```
|
||
|
||
If your svg **does not** contain a single path, you will need to get a designer to join all paths and outline strokes into a single path.
|
||
|
||
#### Step 2.
|
||
|
||
Add your optimized svg file to to `app/images/icons`
|
||
|
||
#### Step 3.
|
||
|
||
Run `yarn start` to generate the `ICON_NAMES` with your added icon.
