Replicating Jekyll's `markdownify` filter in Nunjucks with Eleventy

Jekyll has a useful filter called markdownify that converts a Markdown string into HTML. Nunjucks doesn't have this filter.

I've replicated this in Eleventy by adding this into my .eleventy.js file.

module.exports = function (eleventyConfig) {
  const md = require("markdown-it")({
    html: false,
    breaks: true,
    linkify: true,
  });

  eleventyConfig.addNunjucksFilter("markdownify", (markdownString) =>
    md.render(markdownString)
  );
};
In a Nunjucks template, you can now use {{ someMarkdownString | markdownify | safe }} to convert any Markdown string to HTML.

I'm not 100% sure about the | safe bit, but it's working for me like this.
