Import
import { Icon } from '@dnb/eufemia'
Description
The main Icon component is a wrapper for whatever icon you place within it. This means a span
wrapping an inline SVG
.
You can use whatever you like inside this Icon
component.
Why use it?
You will get several advantages on using it, like:
- Responsiveness in terms of
font-size
- Coloring
- Accessibility
Importing Icons
In case your environment doesn't support tree-shaking, import the icons explicitly.
// Named ES importimport { bell } from '@dnb/eufemia/icons'// or named import with modifierimport { bell as Bell } from '@dnb/eufemia/icons'// Default and explicit ES importimport Bell from '@dnb/eufemia/icons/bell'
Icon Sizes
Exists in the Icon Library
- default
1rem
(16px) - medium
1.5rem
(24px)
Additional Sizes
- small
0.75rem
(12px) - large
2rem
(32px) - custom-size will not be responsive. Width and Height is set as
pixels
Custom project Icons
For decorative or functional icons (not illustrations) use SVG
as it gives the user responsiveness and better accessibility. But it gives you also more control, so you can change the color and size inherited by the parent HTML element.
To optimize your SVG icons to be used with Eufemia, you can follow these steps or get at least, inspired:
- Make sure your SVG icon fits in the two sizes (default of
16px
and medium of24px
) with the correct stroke thickness of1.5px
. - Copy the SVG markup (in Figma,
right click
->Copy as
->Copy as SVG
). - Declutter and remove ID attributes in the markup, so they don't appear twice in your web application DOM. In most cases, you don't need
<defs ... />
and the corresponding ids anyway. - Optimize the SVG. Use e.g. Online SVGOMG by using
Paste markup
. - NB: Do not remove
viewBox
! TheviewBox
will together with some CSS ensure that the icon scales based on the root font-size. - Copy again the optimized markup and paste it into your JSX component (inline) og SVG file.
- Consume the custom icons with either dynamic imports (
import(...)
) if you have many icons, or use static imports, like so:
If you have an SVG loader
import ImportedSVGIcon from 'my-icons/custom_icon.svg'render(<Icon icon={ImportedSVGIcon} />)
Inline the SVG in your JSX
function CustomSVGIcon(props) {return <svg {...props}>...</svg>}render(<Button icon={CustomSVGIcon} />)
SVG import in Create React App
import { ReactComponent as CustomIcon } from './custom_icon.svg'render(<Icon size="medium">{CustomIcon}</Icon>)
Primary Icon
There is also the IconPrimary component, which comes with all the Primary Icons included in the @dnb/eufemia
. you don't have to import the primary icons.
