While using component based designs, how could I create a Prop in which allows me to include an image object, for instance I want to build a component that allows for a title, description and image.

Hi @shadow agate. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
In Astro, you can define and accept props in your components. These props then become available to the component template for rendering HTML. Props are available on the Astro.props global in your frontmatter script.
Here's an example of how you can create a component that accepts a title, description, and image prop:
---
// src/components/MyComponent.astro
import type { ImageMetadata } from 'astro';
interface Props {
title: string;
description: string;
image: string | ImageMetadata;
}
const { title, description, image } = Astro.props;
---
<h2>{title}</h2>
<p>{description}</p>
<img src={image} alt={description} />
In this example, the title, description, and image props are destructured from the global Astro.props object. The image prop can accept a string or an ImageMetadata object, which is a type provided by Astro for handling images.
You can then use this component in another Astro component, layout, or page, and pass these props as attributes:
---
// src/pages/index.astro
import MyComponent from '../components/MyComponent.astro';
import myImage from "../assets/my_image.png";
---
<MyComponent title="My Title" description="My Description" image={myImage} />
In this example, the MyComponent component is imported and used in an Astro page, with the title, description, and image props passed as attributes.
For more information, you can refer to the Astro documentation on component props (https://docs.astro.build/en/basics/astro-components#component-props).

@bleak briar I'm trying to use a template and I get the following return when I try to run the command...
npm run dev
> astroplate@3.4.0 dev
> yarn generate-json && astro dev
sh: yarn: command not found
Let me check the knowledge base for you. One moment! :books:
The error message sh: yarn: command not found indicates that the yarn package manager is not installed or not found in your system's PATH. The npm run dev command is trying to execute a script that uses yarn, but it can't find the yarn command.
You have two options to resolve this issue:
- Install Yarn: You can install Yarn globally on your system. Here's how you can do it:
npm install --global yarn
After installing Yarn, try running npm run dev again.
- Change the package manager: If you prefer to use
npminstead ofyarn, you can modify thedevscript in yourpackage.jsonfile to usenpmcommands. For example, if yourdevscript looks like this:
"dev": "yarn generate-json && astro dev"
You can change it to:
"dev": "npm run generate-json && astro dev"
Make sure that generate-json script is also compatible with npm.
Remember to run npm install before running npm run dev to ensure all dependencies are installed.
If you continue to encounter issues, please refer to the Astro documentation (https://docs.astro.build/) or the Astro GitHub repository (https://github.com/withastro/astro) for further assistance.

@bleak briar what do I change this to if I want to use npm as my package manager?
"packageManager": "yarn@1.22.19",

If you want to use npm as your package manager, you can change the packageManager line in your package.json file to:
"packageManager": "npm"
