Thank you. I tried this and I’m not sure how it works for you, but here it doesn’t. I hit the problem with these Atlassian libraries which I reported some time ago here (and I heard only crickets so far). They seem to be not ESM ready. If I just use the code as you pasted it, e.g.:
import TurndownService from 'turndown';
import { MarkdownTransformer } from '@atlaskit/editor-markdown-transformer';
import { JSONTransformer } from '@atlaskit/editor-json-transformer';
import defaultSchema from '@atlaskit/adf-schema/schema-default';
const turndownService = new TurndownService({ headingStyle: 'atx' });
const markdownTransformer = new MarkdownTransformer(defaultSchema);
const jsonTransformer = new JSONTransformer();
const html = '<strong>Hello world!</strong>';
const markdown = turndownService.turndown(html);
const node = markdownTransformer.parse(markdown);
const adfDoc = jsonTransformer.encode(node);
console.log(adfDoc);
I get the following error:
node index.js

Did you mean to import "@atlaskit/adf-schema/dist/cjs/schema/default-schema.js"?

If I change it from import defaultSchema from '@atlaskit/adf-schema/schema-default'; to @atlaskit/adf-schema/dist/cjs/schema/default-schema.js, then there is another error:

Sorry to not be able to upload the whole project, but this broken forum doesn’t allow me to upload attachments. I got the following error:
Even if it worked, I wouldn’t go with this approach. From HTML to Markdown to ADF seems too risky for me. I thought anyone who dares to invent new formats must also maintain libraries that allow people to convert industry standard formats (HTML) into this ADF, but it seems Atlassian don’t share this opinion.
