Hi @solar vale. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Sure, I can guide you on how to create a card component in Astro that utilizes JSON data. Here are the steps:
- First, you need to import your JSON data into your Astro component. Astro supports importing JSON files directly into your application. Imported files return the full JSON object in the default import. Here's how you can do it:
// Load the JSON object via the default export
import data from './data.json';
Source (https://docs.astro.build/en/guides/imports/#json)
- Next, you need to create your Astro component. You can use the component script to write any JavaScript code that you need to render your template. This can include creating variables that you will reference in your template. Here's an example:
---
import Card from "../src/components/Card.astro";
const result = await container.renderToString(Card, { props: { name: "Hello, world!" },});
---
Source (https://docs.astro.build/en/reference/container-reference/#props-option)
- Now, you can use the imported JSON data in your Astro component. Here's an example of how you can do it:
---
// For TypeScript support
interface Props {
name: string;
};
const { name } = Astro.props;
---
<div>
{name}
</div>
Source (https://docs.astro.build/en/reference/container-reference/#props-option)
Remember, the code fence (---) is used to identify the component script in your Astro component. The JavaScript that you write in it is “fenced in.” It won’t escape into your frontend application, or fall into your user’s hands. You can safely write code here that is expensive or sensitive without worrying about it ever ending up in your user’s browser.
You can even write TypeScript in your component script! Source (https://docs.astro.build/en/basics/astro-components/#the-component-script)
I hope this helps! Let me know if you have any other questions.
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@storm hedge how to map the features from the json?
{data.features.map((feature, index) => (
<div class={card relative overflow-hidden rounded-lg p-6 mb-6 bg-gradient-to-br ${feature.gradient}}>
<div class="flex items-center justify-between mb-2">
<h3 class="text-xl font-bold">{feature.title}</h3>
<svg width="24" height="24" viewBox="0 0 24 24" fill="none" xmlns="http://www.w3.org/2000/svg">
<rect width="24" height="24" fill="white"/>
<path d="M12 6L7 18H17L12 6Z" fill="black"/>
</svg>
</div>
<p class="text-base">{feature.content}</p>
</div>
))}

Let me check the knowledge base for you. One moment! :books:
Sure, you can map over the features array from your JSON data and create a card for each feature in Astro. Here's how you can do it:
---
import data from './data.json';
---
{data.features.map((feature, index) => (
<div class={`card relative overflow-hidden rounded-lg p-6 mb-6 bg-gradient-to-br ${feature.gradient}`}>
<div class="flex items-center justify-between mb-2">
<h3 class="text-xl font-bold">{feature.title}</h3>
<svg width="24" height="24" viewBox="0 0 24 24" fill="none" xmlns="<http://www.w3.org/2000/svg">>
<rect width="24" height="24" fill="white"/>
<path d="M12 6L7 18H17L12 6Z" fill="black"/>
</svg>
</div>
<p class="text-base">{feature.content}</p>
</div>
))}
In this code, we're importing the JSON data and then using the map() function to iterate over each feature in the features array. For each feature, we're creating a new div element with the class card and other classes, and we're using the feature's gradient, title, and content properties to populate the card's content.
Remember, in Astro, you can use JavaScript expressions inside curly braces {} in your HTML code, and they will be evaluated as JavaScript. This is how we're able to use the map() function and other JavaScript code inside our Astro component.
