#Rewrite Web Component in pure Astro
iron parcelBOT
Sure, you can rewrite your Box.js web component in Astro. Here's how you can do it:
---
// Astro Component Script
let { padding, borderWidth, invert } = Astro.props;
// Default values
padding = padding || 'var(--s1)';
borderWidth = borderWidth || 'var(--border-thin)';
invert = invert || false;
// Unique identifier for the style
const styleId = `Box-${padding}-${borderWidth}-${invert}`;
// Style
const style = `
[data-id="${styleId}"] {
padding: ${padding};
border: ${borderWidth} solid;
${invert ? `background-color: var(--color-light); filter: invert(100%);` : ''}
}
`;
---
<!-- Astro Component Markup -->
<div data-id={styleId}>
<slot></slot>
<style>{style}</style>
</div>
In this Astro component, we're using Astro.props to get the properties padding, borderWidth, and invert. We're also providing default values for these properties. We then use these properties to construct a unique identifier styleId and a style string style. In the markup, we apply the styleId as a data attribute to the div and include the style within a style tag.
Please note that in Astro, HTML attributes like class do not automatically pass through to child components. Instead, accept a class prop in the child component and apply it to the root element. When destructuring, you must rename it, because class is a reserved word in JavaScript (source (https://docs.astro.build/en/guides/styling#passing-a-class-to-a-child-component)).
Also, Astro <style> CSS rules are automatically scoped by default. Scoped styles are compiled behind-the-scenes to only apply to HTML written inside of that same component. The CSS that you write inside of an Astro component is automatically encapsulated inside of that component (source (https://docs.astro.build/en/guides/styling#_top)).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

Sure, you can rewrite your Stack.js web component in Astro. Here's how you can do it:
---
// Astro Component Script
let { space, recursive, splitAfter } = Astro.props;
// Default values
space = space || 'var(--s1)';
recursive = recursive || false;
splitAfter = splitAfter || null;
// Unique identifier for the style
const styleId = `Stack-${space}-${recursive}-${splitAfter}`;
// Style
const style = `
[data-id="${styleId}"]${recursive ? '' : ' >'} * + * {
margin-block-start: ${space};
}
${splitAfter ? `
[data-id="${styleId}"]:only-child {
block-size: 100%;
}
[data-id="${styleId}"] > :nth-child(${splitAfter}) {
margin-block-end: auto;
}`
: ''}
`.replace(/\s\s+/g, ' ').trim();
