hi guys,
I have this piece of content type that is a rich text:

   {
            name: "info",
            title: "Info",
            type: "array",
            of: [
                {
                title: "Block",
                type: "block",
                styles: [{title: "Normal", value: "normal"}],
                lists: [],
            },
and I need to render this on my homepage, how do I render this in here:

export async function getStaticProps ({preview = false}) {
  const product = await getClient(preview).fetch(groq`
    *[_type == 'product']{
      name,
      sku,
      image,
      finish,
      info,
    }[0]`)

  return {
      props: {
        product,
      },
    }
}

You'll need to use the @portabletext/react library to render that rich text content in your Next.js app. Here's how to set it up:

First, install the library:

npm install @portabletext/react

Then in your component, import and use the PortableText component:

import { PortableText } from '@portabletext/react'

export default function Product({ product }) {
  return (
    <div>
      <h1>{product.name}</h1>
      <PortableText value={product.info} />
    </div>
  )
}

export async function getStaticProps ({ preview = false }) {
  const product = await getClient(preview).fetch(groq`
    *[_type == 'product']{
      name,
      sku,
      image,
      finish,
      info,
    }[0]`)

  return {
    props: {
      product,
    },
  }
}

The basic implementation is that simple! The PortableText component takes your info array and automatically renders it as proper HTML.

If you want to customize how the content looks, you can pass custom components:

const components = {
  block: {
    normal: ({children}) => <p className="my-custom-paragraph">{children}</p>,
  },
  marks: {
    strong: ({children}) => <strong className="font-bold">{children}</strong>,
  }
}

<PortableText value={product.info} components={components} />

Note: If you're using the older @sanity/block-content-to-react library anywhere, you should migrate to @portabletext/react as it's the modern, officially supported version. The main difference is that the old node prop is now called value.
