object-fit-images polyfill

If you need to support older browsers, you can use this polyfill for object-fit: https://github.com/fregante/object-fit-images. This package already includes necessary syntax to work with the polyfill - all you have to do is include the polyfill.

<script src="//cdnjs.cloudflare.com/ajax/libs/object-fit-images/3.2.4/ofi.min.js"></script>
<script>
    objectFitImages();
</script>

Usage

import { DocumentNode, HeadingNode } from '@prezly/story-content-format';
import { Renderer, Component } from '@prezly/slate-renderer';

const documentNode: DocumentNode = {
    type: DocumentNode.TYPE,
    version: '0.50',
    children: [
        {
            type: HeadingNode.Type.HEADING_ONE,
            children: [{ text: 'Hello world!' }],
        },
    ],
};

export function Content() {
    return <Renderer nodes={documentNode} />;
}

// You can also override default renders by
// declaring custom renderers as children `<Component>` elements
export function ContentWithCustomHeadings() {
    return (
        <Renderer nodes={documentNode}>
            <Component
                match={isHeadingNode}
                component={({ children, node }) => <div style={{ color: 'red' }}>{children}</div>}
            />
        </Renderer>
    );
}

Development

There is a sandbox app in this repository with Hot Module Replacement. It will automatically include updates of any code changes you make locally. To start it, simply run pnpm start:

pnpm install
pnpm start

Visual regression tests

Visual regression tests use Playwright against a static Storybook build. Docker keeps local screenshots consistent with CI.

pnpm test:visual

Regenerate the committed snapshots after an intentional visual change:

pnpm test:visual:update

Failed CI runs upload the Playwright report and image diffs in the playwright-report artifact.
