feat: Support RenderMarkdown API

[sgalcheung]

To support Astro 5.9.0 new feat: adds support for rendering markdown in loaders #13850

Compatible with PR: Restrict remark/rehype plugins usage #3274

Implement key code:

const id = item.id;
const parsedData = await parseData({
  id,
  data: JSON.parse(JSON.stringify(item)),
});

const content = item.data?.content?.iv;

store.set({
  id,
  data: parsedData,
  rendered: content ? await renderMarkdown(content) : undefined,
});

This code has a convention that renderMarkdown must specify a markdown field to render, so we assume that the schema you want to cache uses the content field to store markdown content.

Then, you can use the render method as usual for local collection content.

---
import { getEntry, render } from 'astro:content';
const entry = await getEntry('my-collection', Astro.params.id);
const { Content } = await render(entry);
---
<Content />
