To use an image asset that's shipped with patternfly core, you'll prefix the paths with @pfassets
. @pfassets
is an alias for the patternfly assets directory in node_modules.
import imgSrc from '@pfassets/images/g_sizing.png';
Then you can use it like:
<img src={imgSrc} alt="Some image" />
You can use a similar technique to import assets from your local app, just prefix the paths with. @app
.
import loader from '@app/assets/images/loader.gif';
<img src={loader} alt="Content loading />
Inlining SVG in the app's markup is also possible.
import logo from '@app/assets/images/logo.svg';
Then you can use it like:
<span dangerouslySetInnerHTML={{__html: logo}} />
You can also use SVG to apply background images with CSS. To do this, your svg's must live under a bgimages
directory. This is necessary because you may need to use SVG's in several other context (inline images, fonts, icons, etc.) and so we need to be able to differentiate between these usages so the appropriate loader is invoked.
body {
background: url(./assets/bgimages/img_avatar.svg);

- For accessibility compliance, we use react-axe
- To keep our bundle size in check, we use webpack-bundle-analyzer
- To keep our code formatting in check, we use prettier
- To keep our code logic and test coverage in check, we use jest
