0.15.0-beta.1

Minor Changes

  • #5769 93e633922 Thanks @bholmesdev! - Introduce a smartypants flag to opt-out of Astro's default SmartyPants plugin.

    {
  markdown: {
    smartypants: false,
  }
}

    Migration

    You may have disabled Astro's built-in plugins (GitHub-Flavored Markdown and Smartypants) with the extendDefaultPlugins option. This has now been split into 2 flags to disable each plugin individually:

    • markdown.gfm to disable GitHub-Flavored Markdown
    • markdown.smartypants to disable SmartyPants
    // astro.config.mjs
import { defineConfig } from 'astro/config';

export default defineConfig({
  markdown: {
-   extendDefaultPlugins: false,
+   smartypants: false,
+   gfm: false,
  }
});

Patch Changes

0.15.0-beta.0

Minor Changes

  • #5687 e2019be6f Thanks @bholmesdev! - Give remark and rehype plugins access to user frontmatter via frontmatter injection. This means data.astro.frontmatter is now the complete Markdown or MDX document's frontmatter, rather than an empty object.

    This allows plugin authors to modify existing frontmatter, or compute new properties based on other properties. For example, say you want to compute a full image URL based on an imageSrc slug in your document frontmatter:

    export function remarkInjectSocialImagePlugin() {
  return function (tree, file) {
    const { frontmatter } = file.data.astro;
    frontmatter.socialImageSrc = new URL(frontmatter.imageSrc, 'https://my-blog.com/').pathname;
  };
}

    Content Collections - new remarkPluginFrontmatter property

    We have changed inject frontmatter to modify frontmatter in our docs to improve discoverability. This is based on support forum feedback, where "injection" is rarely the term used.

    To reflect this, the injectedFrontmatter property has been renamed to remarkPluginFrontmatter. This should clarify this plugin is still separate from the data export Content Collections expose today.

    Migration instructions

    Plugin authors should now check for user frontmatter when applying defaults.

    For example, say a remark plugin wants to apply a default title if none is present. Add a conditional to check if the property is present, and update if none exists:

    export function remarkInjectTitlePlugin() {
  return function (tree, file) {
    const { frontmatter } = file.data.astro;
+    if (!frontmatter.title) {
      frontmatter.title = 'Default title';
+    }
  }
}

    This differs from previous behavior, where a Markdown file's frontmatter would always override frontmatter injected via remark or reype.

  • #5684 a9c292026 Thanks @bholmesdev! - Refine Markdown and MDX configuration options for ease-of-use.

    Markdown

    • Remove remark-smartypants from Astro's default Markdown plugins.
    • Replace the extendDefaultPlugins option with a simplified gfm boolean. This is enabled by default, and can be disabled to remove GitHub-Flavored Markdown.
    • Ensure GitHub-Flavored Markdown is applied whether or not custom remarkPlugins or rehypePlugins are configured. If you want to apply custom plugins and remove GFM, manually set gfm: false in your config.

    MDX

    • Support all Markdown configuration options (except drafts) from your MDX integration config. This includes syntaxHighlighting and shikiConfig options to further customize the MDX renderer.
    • Simplify extendDefaults to an extendMarkdownConfig option. MDX options will default to their equivalent in your Markdown config. By setting extendMarkdownConfig to false, you can "eject" to set your own syntax highlighting, plugins, and more.

    Migration

    To preserve your existing Markdown and MDX setup, you may need some configuration changes:

    Smartypants manual installation

    Smartypants has been removed from Astro's default setup. If you rely on this plugin, install remark-smartypants and apply to your astro.config.*:

    // astro.config.mjs
import { defineConfig } from 'astro/config';
+ import smartypants from 'remark-smartypants';

export default defineConfig({
  markdown: {
+   remarkPlugins: [smartypants],
  }
});
    Migrate extendDefaultPlugins to gfm

    You may have disabled Astro's built-in plugins (GitHub-Flavored Markdown and Smartypants) with the extendDefaultPlugins option. Since Smartypants has been removed, this has been renamed to gfm.

    // astro.config.mjs
import { defineConfig } from 'astro/config';

export default defineConfig({
  markdown: {
-   extendDefaultPlugins: false,
+   gfm: false,
  }
});

    Additionally, applying remark and rehype plugins no longer disables gfm. You will need to opt-out manually by setting gfm to false.

    Migrate MDX's extendPlugins to extendMarkdownConfig

    You may have used the extendPlugins option to manage plugin defaults in MDX. This has been replaced by 2 flags:

    • extendMarkdownConfig (true by default) to toggle Markdown config inheritance. This replaces the extendPlugins: 'markdown' option.
    • gfm (true by default) to toggle GitHub-Flavored Markdown in MDX. This replaces the extendPlugins: 'defaults' option.

Patch Changes

0.14.0

Minor Changes

  • #5654 2c65b433b Thanks @delucis! - Run heading ID injection after user plugins

    ⚠️ BREAKING CHANGE ⚠️

    If you are using a rehype plugin that depends on heading IDs injected by Astro, the IDs will no longer be available when your plugin runs by default.

    To inject IDs before your plugins run, import and add the rehypeHeadingIds plugin to your rehypePlugins config:

    // astro.config.mjs
+ import { rehypeHeadingIds } from '@astrojs/markdown-remark';
import mdx from '@astrojs/mdx';

export default {
  integrations: [mdx()],
  markdown: {
    rehypePlugins: [
+     rehypeHeadingIds,
      otherPluginThatReliesOnHeadingIDs,
    ],
  },
}
