Markdown

There are many ways to use markdown files with Content Collections. We can use packages like react-markdown to compile the files at runtime. Or we can use remark to compile the files at build time. The package @content-collections/markdown simplifies the usage of remark with Content Collections. Let's see how we can use it.

First we have to install the package @content-collections/markdown package.

pnpm add @content-collections/markdown

After installing the package, we can use the compileMarkdown function to compile the content of our document.

import { defineCollection, defineConfig } from "@content-collections/core";
import { compileMarkdown } from "@content-collections/markdown";

const posts = defineCollection({
  name: "posts",
  directory: "content",
  include: "*.md",
  schema: (z) => ({
    title: z.string()
  }),
  transform: async (document, context) => {
    const html = await compileMarkdown(context, document);
    return {
      ...document,
      html,
    };
  },
});

export default defineConfig({
  collections: [posts],
});

Now we can use the compiled html in our project. The following snippet shows an example with React.

import { allPosts } from "content-collections";

export default function App() {
  return (
    <main>
      <h1>Posts</h1>
      <ul>
        {allPosts.map((post) => (
          <li key={post._meta.path}>
            <h2>{post.title}</h2>
            <div dangerouslySetInnerHTML={{ __html: post.html }} />
          </li>
        ))}
      </ul>
    </main>
  );
}

And the next snippet shows an example with Svelte.

<script>
  import { allPosts } from "content-collections";
</script>

<h1>Posts</h1>

<ul>
  {#each allPosts as post}
    <li>
      <h2>{post.title}</h2>
      <div>{@html post.html}</div>
    </li>
  {/each}
</ul>

And the last snippet shows an example with Solid.

import { allPosts } from "content-collections";

export default function App() {
  return (
    <main>
      <h1>Posts</h1>
      <ul>
        {allPosts.map((post) => (
          <li>
            <h2>{post.title}</h2>
            <div innerHTML={post.html} />
          </li>
        ))}
      </ul>
    </main>
  );
}

And that's it!
