React component `props` type

[maiden lava]

So I have this Astro file:

 <MyComponent socials={socials} client:only="react">
            <div class="relative" slot="one-to-react">
              "asdasdzzz"
            </div>

            <p slot="two-to-react">
              "zxczxczxc"
            </p>
          </MyComponent>

And this is my react component:

export default function MyComponent(props: any) { 
return <div>
{props.twoToReact}
{props.oneToReact}
</div>
}

But using any is not useful and I don't know how can I type the props, that are generated by Astro:
two slots, and the client attribute
and also the socials thing is the data returned by getCollection() so again, I don't know how to specify the type for these things

Can someone please help and explain if there is any way to be type-safe in this use case?

Hi @maiden lava. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Astro supports TypeScript, which can help you define the shapes of objects and components in your code, preventing runtime errors. You can type your component props using TypeScript.

For the socials prop, you can use the CollectionEntry utility to correctly type your component props. This utility takes a string argument that matches the name of your collection schema, and will inherit all of the properties of that collection’s schema. Here's an example:

import type { CollectionEntry } from 'astro:content';
interface Props { 
  socials: CollectionEntry<'your-collection-name'>;
  // other props...
}

Replace 'your-collection-name' with the name of your collection schema.

For the slots, Astro does not need to receive {children} as a function prop and will automatically render child content in a <slot />. If you have multiple sets of children, you can use named slots (https://docs.astro.build/en/core-concepts/astro-components/#named-slots). However, the type checking for slots is not explicitly mentioned in the provided extracts.

For the client attribute, it's not clear from the provided extracts how to type this prop in TypeScript.

Remember, the Astro dev server won’t perform any type checking, but you can use a separate script (https://docs.astro.build/en/guides/typescript/#type-checking) to check for type errors from the command line.

For more information, you can refer to the Astro TypeScript guide (https://docs.astro.build/en/guides/typescript/).

@vernal ember Is there any way to also get the types for something like socials.data.type ? like what you did with CollectionEntry<'your-collection-name'> but accessing deeper types?

Let me check the knowledge base for you. One moment! :books:

The CollectionEntry utility type provided by Astro gives you access to the properties of your collection schema. If your collection schema has a data property that itself has a type property, you should be able to access it like so:

import type { CollectionEntry } from 'astro:content';

interface Props {
  socials: CollectionEntry<'your-collection-name'>;
  // other props...
}

// Accessing the type property
const type = props.socials.data.type;

Replace 'your-collection-name' with the name of your collection schema.

However, the exact typing would depend on the structure of your collection schema. If you have a more complex or nested structure, you might need to define additional types or interfaces to accurately represent your data.

For more information, you can refer to the Astro TypeScript guide (https://docs.astro.build/en/guides/typescript/).

@vernal ember i want this to use as a prop type not inside the function body

If you want to access nested properties in your TypeScript types, you can define a more specific type or interface that represents the structure of your data.

Assuming your data object has a type property, you could define a new type or interface that includes this property. Here's an example:

import type { CollectionEntry } from 'astro:content';

interface DataType {
  type: string; // replace 'string' with the actual type of 'type'
  // include other properties if needed
}

interface CollectionEntryData extends CollectionEntry<'your-collection-name'> {
  data: DataType;
}

interface Props {
  socials: CollectionEntryData;
  // other props...
}

In this example, DataType is a new interface that represents the structure of your data object. CollectionEntryData then extends the CollectionEntry utility type and overrides the data property with your new DataType.

Replace 'your-collection-name' with the name of your collection schema, and 'string' with the actual type of your type property.

For more information, you can refer to the Astro TypeScript guide (https://docs.astro.build/en/guides/typescript/).
