Eleventy Plugin Unified

Use the unified ecosystem in Eleventy.

You can render, transform and lint:

• markdown with the remark ecosystem.
• html with the rehype ecosystem.
• text with the retext ecosystem.

Install

npm install eleventy-plugin-unified remark-slug

// .eleventy.config.cjs
const EleventyUnifiedPlugin = require("eleventy-plugin-unified");

module.exports = function (eleventyConfig) {
  eleventyConfig.addPlugin(EleventyUnifiedPlugin, ["remark-slug"]);
};

Then with a markdown file with:

# Hello, world

It will render like this:

<h1 id="hello-world">Hello, world</h1>
