Tips for migrating from WordPress to Sanity, including using WPGraphQL and block tools.

import SanitySchema from '@sanity/schema';
import blockTools from '@sanity/block-tools';
import Sanity from '@sanity/client';
import { JSDOM } from 'jsdom';

const contentType = SanitySchema.compile({
    name: 'default',
    types: [
        {
            name: 'blocks',
            type: 'array',
            of: [{ type: 'block' }],
        },
    ],
}).get('blocks');

const htmlToBlocks = (html: string) => {
    return blockTools.htmlToBlocks(html, contentType, {
        parseHtml: (html) => new JSDOM(html).window.document,
    });
};

const sanity = Sanity({/* init sanity client */});

async function main() {
  const allPosts = await getAllWordPressPostsViaTheRestApi();

  const t = sanity.transaction();

  for (const post of allPosts) {
    t.createOrReplace({
      _id: post.id.toString(),
      content: htmlToBlocks(post.content.rendered),
    });
  }

  await t.commit();
}

main().catch(e => {
  console.error(e);
  process.exit(1);
});
