objectDecorators syntax for cssClasses with space-config

Tricks & Techniques
1

Hi all,
It was just not obvious to me how to to use objectDecorators to inject cssClasses, the manual only shows the decoration set within frontmatter in place, not the space-config case.
cssClasses attribute is a list (hence the plural) and has to be formatted as one.
Not being a JS dev, it took me some time and going through pull request comments on decorations to get to the proper syntax.
Posting it here, for any non JS-savy future users:

objectDecorators:
- where: 'tag = "page" and tags = "holiday"'
  attributes:
    pageDecoration:
      cssClasses: "['christmas-decoration']"
      prefix: "'🎄 '"

Ah. Thanks for that. That is indeed a bit unintuitive. I hadn’t tried doing this yet.
