Create a JSON Endpoint for All Posts in Jekyll

Last reviewed on January 23, 2020

Create posts.json (you can name this file whatever you want) in the root of your Jekyll site with the following contents:

  {% raw %}{% for post in site.posts %}
      "url": "{{post.url}}",
      "title": {{post.title | jsonify}},
      "content": {{post.content | jsonify}},
      "keywords": "{{post.keywords}}",
      "created": "{{ | date: "%B %e, %Y"}}"
    }{% unless forloop.last %},{% endunless %}
  {% endfor %}{% endraw %}

Visit /posts.json and voila!

This example used the site.posts collection but other collections can be used too.

With this JSON endpoint, we can make AJAX requests to it. I did this for the search bar on this blog. For example:

(async () => {
  const response = await fetch('/posts.json');
  const posts = await response.json();
