Convert all content to Markdown – fluent-wp-client

Fetch every published post and convert content.rendered — the server-side rendered HTML WordPress returns by default — to individual Markdown files.

Adapting this for a custom post type

Not all CPTs expose content. Before running this against a custom post type, call .describe() to confirm the field is registered:

const desc = await wp.content('recipes').describe();
// desc.schemas.item contains the full REST schema for the resource

If content is absent, the rendered value will be an empty string rather than an error. See Custom endpoints for how sparse CPTs work.

Install Turndown

npm install turndown @types/turndown

to-markdown.ts

import { WordPressClient } from 'fluent-wp-client';
import TurndownService from 'turndown';
import { writeFileSync, mkdirSync } from 'node:fs';

const wp = new WordPressClient({ baseUrl: 'https://example.com' });
const td = new TurndownService();

const posts = await wp.content('posts').listAll({ status: 'publish' });

mkdirSync('content', { recursive: true });

for (const post of posts) {
  const body = td.turndown(post.content.rendered);
  writeFileSync(`content/${post.slug}.md`, `# ${post.title.rendered}\n\n${body}`);
}

console.log(`Converted ${posts.length} posts.`);
