Hi @jade summit. 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 type your component props using TypeScript. To do this, you would define a Props interface in your component frontmatter. Here's how you can type the pageInfo object to the PageInfo type:
---
interface Props {
pageInfo: PageInfo;
}
const { pageInfo } = Astro.props;
---
In this example, PageInfo is a type that you would have defined elsewhere in your code. If PageInfo is a complex object, you would define it like this:
interface PageInfo {
title: string;
description: string;
// other properties...
}
Then you can use it in your Astro component as shown above.
Remember, the Astro VSCode Extension will automatically look for the Props interface and give you proper TypeScript support when you use that component inside another template.
For more information, you can refer to the Astro documentation on TypeScript and component props (https://docs.astro.build/en/guides/typescript/#component-props).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

Let me check the knowledge base for you. One moment! :books:
If you want to type the pageInfo object outside of the Astro component, you can use JSDoc notation to provide type definitions manually to VSCode. Here's how you can do it:
---
export default /** @type {import('astro').AstroUserConfig & { pageInfo: PageInfo }} */ {
// your configuration options here...
// <https://docs.astro.build/en/reference/configuration-reference/>
}
---
In this example, PageInfo is a type that you would have defined elsewhere in your code. If PageInfo is a complex object, you would define it like this:
interface PageInfo {
title: string;
description: string;
// other properties...
}
Then you can use it in your Astro component as shown above.
