Hi @swift thunder. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
#Array passed from an astro file to a react component, appears as an object in the component
mortal scarabBOT
Astro parses children passed into a React component from an Astro component as plain strings, not React nodes. This could be the reason why your array is appearing as an object with the array as a property of that object.
For example, the <ReactComponent /> below will only receive a single child element:
import ReactComponent from './ReactComponent';
<ReactComponent> <div>one</div> <div>two</div></ReactComponent>
If you are using a library that expects more than one child element to be passed, you might find this to be a blocker.
You can set the experimental flag experimentalReactChildren to tell Astro to always pass children to React as React virtual DOM nodes. There is some runtime cost to this, but it can help with compatibility. You can enable this option in the configuration for the React integration:
import { defineConfig } from 'astro/config';
import react from '@astrojs/react';
export default defineConfig({
// ...
integrations: [
react({
experimentalReactChildren: true,
}),
],
});
This information is extracted from the Astro documentation (https://docs.astro.build/en/guides/integrations-guide/react/#children-parsing).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@mortal scarab I'm not passing the array as a child but as a property. Example: <ReactComponent someArray={someArray} />

Let me check the knowledge base for you. One moment! :books:
Astro allows you to pass properties (props) from Astro components to framework components, such as React. If you're passing an array as a prop to a React component and it's appearing as an object, it might be due to how the data is being handled within the React component itself, not necessarily an issue with Astro.
Here's an example of passing props from Astro to a React component:
import TodoList from '../components/TodoList.jsx';
<div>
<TodoList initialTodos={["learn Astro", "review PRs"]} />
</div>
In this example, an array ["learn Astro", "review PRs"] is passed as a prop initialTodos to the TodoList React component.
If you're experiencing issues, you might want to check how you're accessing and using the someArray prop within your React component. Ensure that you're correctly accessing the array prop in your React component like so:
function ReactComponent({ someArray }) {
// You can now use someArray as an array within your component
}
