Help running a post processing step

[0xQilin]

Hi team,

I'm trying to pull out a list of IDs that are within my MDX which will match the regex of const TWEET_RE = /<StaticTweet\sid="[0-9]+"\s\/>/g; that I can then use to perform getStaticProps.

Mainly trying to follow this specific tutorial : https://blog.maximeheckel.com/posts/static-tweets-with-mdx-nextjs/

I was wondering if there's an easy way to modify the makeSource config folder so that I can simply map over the individual file contents within my target folder to extract these IDs.

This is my existing makeSource config.

export default makeSource({
  contentDirPath: "posts",
  documentTypes: [Post],
  mdx: {
    rehypePlugins: [
      [
        rehypePrettyCode,
        {
          // theme: "github-dark",
          theme: JSON.parse(readFileSync(themePath, "utf-8")),
          onVisitLine(node: any) {
            // Prevent lines from collapsing in `display: grid` mode, and allow empty
            // lines to be copy/pasted
            if (node.children.length === 0) {
              node.children = [{ type: "text", value: " " }];
            }
          },
          onVisitHighlightedLine(node: any) {
            node.properties.className.push("line--highlighted");
          },
          onVisitHighlightedWord(node: any) {
            node.properties.className = ["word--highlighted"];
          },
        },
      ],
    ],
  },
});

Thank you so much!
