Configurable og-image

[kamilkisiela]

Instead of hard-coding an og-image based on two properties provided by docs configuration title, websiteName, we should allow to provide a custom url to og-image.

It could be:

interface OgImageProps {
  title: string;
  description?: string;
}

config = {
  ogImage(props: OgImageProps) {
    return '....';
  }
}

We could use it like this:

config = {
   ogImage({title, description}) {
     return `https://.......?product=HIVE&title=${title}&extra={description}`;
   }
}

Why?

No need to pass product (ex value: HIVE) to the configuration and we could also experiment with additional text in the og-image or even completely different og-image.
