Hello everyone! ๐Ÿ™‚
Im trying to make a custom preview of a embed youtube video but it doesnt work. What am i doing wrong? Its version 3.


import { defineField, defineType } from "sanity";
import getYouTubeId from "get-youtube-id";

interface Youtube {
  _type: "youtube";
  url: string;
}

interface PreviewProps {
  media: React.ReactNode;
  title: string;
}

const YoutubePreview: React.FC<PreviewProps> = ({ media, title }) => {
  const id = getYouTubeId(media as string);
  const embedUrl = `<https://www.youtube.com/embed/${id}>`;
  return (
    <div>
      <h2>{title}</h2>
      <iframe
        width="560"
        height="315"
        src={embedUrl}
        title="YouTube video player"
        frameBorder="0"
        allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture"
        allowFullScreen
      ></iframe>
    </div>
  );
};

export default defineType({
  name: "youtube",
  type: "object",
  fields: [
    {
      name: "url",
      title: "URL",
      type: "url",
      validation: (Rule) => Rule.required(),
    },
  ],
  preview: {
    select: {
      url: "url",
    },
    prepare(selection) {
      const { url } = selection;
      if (!url) {
        return {
          title: "Missing YouTube URL",
          media: <div>Missing YouTube URL</div>,
        };
      }
      const id = getYouTubeId(url);
      const media = (
        <img
          src={`<https://i.ytimg.com/vi/${id}/hqdefault.jpg>`}
          alt="Video thumbnail"
        />
      );
      return {
        title: "YouTube Video",
        media,
      };
    },
    component: YoutubePreview,
  },
}) as unknown as Youtube;

Ah you dont want to just define the preview.media (but as you can see it does work in general ๐Ÿ˜‰ ), but define the preview component for the whole type. At the moment youโ€™re only defining a custom component for media.you need to define this on the type bot in the preview, but I would still select and prepare values as do
๐Ÿ™‚
components:{
  preview: YoutubePreview,
}
