I have multiple React files in a folder:

content
  - blog-post-1.jsx
  - blog-post-2.jsx
  - blog-post-3.jsx

I now want to go through the files in this folder and extract the frontmatter of each file. I was thinking of exporting a javascript object from each file, e.g.:

// e.g.: blog-post-1.jsx
export const frontmatter = {
  title: "My Title",
  published: "02/12/2024"
}

But I am stuck here: How could I map through the folder and automatically grab the frontmatter object from each file, without knowing the exact number of files in the content folder?
