Hi @royal gyro. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

Sure, you can add remark and rehype plugins to MDX and use Prism for syntax highlighting in Astro. Here are the steps:

Install the necessary plugins and modules. For example, if you want to use remark-toc and rehype-minify-html, you would install them using npm or yarn.
Configure your astro.config.mjs file to use these plugins and Prism for syntax highlighting. Here's an example:

import { defineConfig } from 'astro/config';
import mdx from '@astrojs/mdx';
import remarkToc from 'remark-toc';
import rehypeMinifyHtml from 'rehype-minify-html';

export default defineConfig({
  integrations: [
    mdx({
      syntaxHighlight: 'shiki',
      shikiConfig: { theme: 'dracula' },
      remarkPlugins: [remarkToc],
      rehypePlugins: [rehypeMinifyHtml],
      remarkRehype: { footnoteLabel: 'Footnotes' },
      gfm: false,
    }),
  ],
});

In this example, remarkToc and rehypeMinifyHtml are used as remark and rehype plugins respectively. The syntaxHighlight option is set to 'shiki', which is a Prism theme.

If you opt to use Prism, you need to bring your own CSS stylesheet for syntax highlighting to appear. Choose a premade stylesheet from the available Prism Themes (https://github.com/PrismJS/prism-themes), add this stylesheet to your project’s public/ directory, and load this into your page’s <head> in a layout component via a <link> tag.

Please note that MDX does not support passing remark and rehype plugins as a string. You should install, import, and apply the plugin function instead.

For more details, you can refer to the Astro documentation (https://docs.astro.build/en/guides/integrations-guide/mdx/).

@pulsar wharf how can i generate a table of contents for it?

pulsar wharfBOT Oct 2, 2023, 11:44 AM

Let me check the knowledge base for you. One moment! :books:

#

To generate a table of contents in Astro, you can use the remark-toc plugin. Here's how you can do it:

Install the remark-toc plugin using npm or yarn.
Add the remark-toc plugin to your astro.config.mjs file. Here's an example:

import { defineConfig } from 'astro/config';
import remarkToc from 'remark-toc';
import { rehypeAccessibleEmojis } from 'rehype-accessible-emojis';

export default defineConfig({
  markdown: {
    remarkPlugins: [remarkToc],
    rehypePlugins: [rehypeAccessibleEmojis],
  },
});

In this example, remarkToc is used as a remark plugin to generate a table of contents.

Please note that by default, remarkToc requires a “ToC” or “Table of Contents” heading (case-insensitive) on the page to show the table of contents.

For more details, you can refer to the Astro documentation (https://docs.astro.build/en/guides/markdown-content/).

@pulsar wharf can u give steps to use one dark theme and prism for syntax highlighting for astrojs mdx

pulsar wharfBOT Oct 2, 2023, 11:45 AM

#

Let me check the knowledge base for you. One moment! :books:

#

Sure, you can use Prism for syntax highlighting and apply a dark theme in Astro. Here are the steps:

Install the necessary modules. For Prism, you need to install the @astrojs/prism package:

npm install @astrojs/prism

Choose a dark theme from the available Prism Themes (https://github.com/PrismJS/prism-themes). Download the CSS file for the theme and add it to your project’s public/ directory.
Load the theme into your page’s <head> in a layout component via a <link> tag.
Configure your astro.config.mjs file to use Prism for syntax highlighting. Here's an example:

import { defineConfig } from 'astro/config';
import mdx from '@astrojs/mdx';

export default defineConfig({
  markdown: {
    syntaxHighlight: 'prism',
  },
  integrations: [
    mdx({
      syntaxHighlight: 'prism',
    }),
  ],
});

To use the Prism highlighter component in your MDX files, you can do so like this:

import { Prism } from '@astrojs/prism';

<Prism lang="js" code={`const foo = 'bar';`} />

This component provides language-specific syntax highlighting for code blocks by applying Prism’s CSS classes. Note that you need to provide a Prism CSS stylesheet (or bring your own) for syntax highlighting to appear.

For more details, you can refer to the Astro documentation (https://docs.astro.build/en/guides/markdown-content/#prism-configuration).

@pulsar wharf and is there any way i can preprocess mdx? like i wana make a table of contents generator myself and modify data of collection returned?

pulsar wharfBOT Oct 2, 2023, 11:47 AM

Let me check the knowledge base for you. One moment! :books:

#

Yes, you can preprocess MDX and modify the data of a collection in Astro. Here's how you can do it:

Preprocessing MDX: You can use remark or rehype plugins to modify your frontmatter directly. Here's an example of how to add a customProperty to the data.astro.frontmatter property from your plugin’s file argument:

export function exampleRemarkPlugin() {
  return function (tree, file) {
    file.data.astro.frontmatter.customProperty = 'Generated property';
  }
}

Then, apply this plugin to your markdown or mdx integration config:

import { defineConfig } from 'astro/config';
import { exampleRemarkPlugin } from './example-remark-plugin.mjs';

export default defineConfig({
  markdown: {
    remarkPlugins: [exampleRemarkPlugin]
  },
});

Now, every Markdown or MDX file will have customProperty in its frontmatter, making it available when importing your markdown and from the Astro.props.frontmatter property in your layouts (source (https://docs.astro.build/en/guides/markdown-content/)).

Modifying Collection Data: You can access the modified frontmatter inside of a content entry by using the remarkPluginFrontmatter property returned from render(). Here's an example:

import { getEntry } from 'astro:content';
const blogPost = await getEntry('blog', 'post-1');
const { remarkPluginFrontmatter } = await blogPost.render();

#

<p>{blogPost.data.title} — {remarkPluginFrontmatter.readingTime}</p>

Please note that the remark and rehype pipelines only run when your content is rendered, which explains why `remarkPluginFrontmatter` is only available after you call `render()` on your content entry. In contrast, `getCollection()` and `getEntry()` cannot return these values directly because they do not render your content (**source** (<https://docs.astro.build/en/guides/content-collections/>)).

Remember, modifying frontmatter with remark is not recommended as it is handled separately from your type-safe `schema`, and will not reflect any changes or defaults applied through Astro. Use at your own risk!

@pulsar wharf how will add prism themes?

pulsar wharfBOT Oct 2, 2023, 12:55 PM

#

Let me check the knowledge base for you. One moment! :books:

#

To add Prism themes for syntax highlighting in Astro, follow these steps:

Choose a premade stylesheet from the available Prism Themes (https://github.com/PrismJS/prism-themes).
Download the CSS file for the theme and add this stylesheet to your project’s public/ directory.
Load the theme into your page’s <head> in a layout component via a <link> tag. Here's an example:

<head>
  <!-- Local: /public/styles/prism-theme.css -->
  <link rel="stylesheet" href="/styles/prism-theme.css" />
</head>

In this example, replace prism-theme.css with the name of your Prism theme CSS file.

Configure your astro.config.mjs file to use Prism for syntax highlighting. Here's an example:

import { defineConfig } from 'astro/config';
import mdx from '@astrojs/mdx';

export default defineConfig({
  markdown: {
    syntaxHighlight: 'prism',
  },
  integrations: [
    mdx({
      syntaxHighlight: 'prism',
    }),
  ],
});
