How can I add extra frontmatter to posts

[christoph88]

I want to add extra frontmatter to posts e.g. the field price or subscriptionUrl.
I tried editing the types.ts file and add the fields there.

When I console.log in utils/blog.ts the new frontmatter does not seem to arrive.

I am really stuck on this, how should I fix this?

src/utlils/blog.ts

When I console log data here the new frontmatter is not present.
Despite updating src/types.ts with the new field i would expect ...rest to pick it up.

const getNormalizedPost = async (post: CollectionEntry<'post'>): Promise<Post> => {
  const { id, slug: rawSlug = '', data } = post;
  const { Content, remarkPluginFrontmatter } = await post.render();

  const {
    tags: rawTags = [],
    category: rawCategory,
    author = 'Anonymous',
    publishDate: rawPublishDate = new Date(),
    ...rest
  } = data;

Looks like I forgot to edit content/config.ts, which fixed it.
