Astro Content Layer API — Quick Notes

Astro 5’s Content Collections use the glob loader to load Markdown/MDX:

import { defineCollection, z } from 'astro:content';
import { glob } from 'astro/loaders';

const blog = defineCollection({
  loader: glob({ pattern: '**/*.md', base: './src/content/blog' }),
  schema: z.object({ title: z.string() }),
});

For rendering, use render() instead of entry.render():

const { Content, headings } = await render(entry);

headings plugs straight into the floating TOC component.
