I'm having troubles using front matter in my layouts. It simply displays out the front matter to the page without creating the data needed for my layout.

Here goes the code:

/src/_includes/layouts/base.html

---
rightLinks : [
        {
            "icon": "mail_outline",
            "href": "https://google.com"
        }
    ]
---
<!DOCTYPE html>
<html lang="es-AR">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>{{ title }}</title>
  <link href="https://fonts.googleapis.com/icon?family=Material+Icons"
      rel="stylesheet">

  <link rel="stylesheet" href="/css/global.css">
</head>
<body>
  <!-- top-nav try to use rightLinks data from this layout -->
  {% include "partials/top-nav.html" %}
  {% include "partials/main-nav.html" %}
  <main tabindex="-1" id="main-content">{% block content %}{% endblock %}</main>
</body>
</html>

/src/_includes/layouts/home.html

{% extends "layouts/base.html" %} 
{% block content %}

<section class="hero is-black is-fullheight-with-navbar hero-home">
  <div class="hero-body">
    <div class="container">
      <div>
        <h1 class="title text-black text-huge">
          Nexus Materiales Eléctricos
        </h1>
        <h2 class="subtitle is-4">
          Somos mayoristas en insúmos eléctricos de calidad.
        </h2>
      </div>
      <div class="mt-6">
        <a href="/marcas" class="button is-rounded is-large is-dark is-uppercase text-semi-black">
          ver marcas
        </a>
      </div>
    </div>
  </div>
</section>

<section class="section has-background-white">
  <h2 class="title">Nuestras marcas destacadas</h2>
  <h3 class="subtitle">Calidad y seguridad</h3>
</section>

{% endblock %}

/src/index.md

---
title: 'Hello World!'
layout: 'layouts/home'
---

I get as a visual result the actual string at the top: enter image description here

It seems to me that Eleventy, for some reason, is skipping the front matter.

Here is my Eleventy configuration file:

module.exports = function(config) {
    config.addWatchTarget("./src/sass/");
    config.addPassthroughCopy('./src/images')

    // Return your Object options:
    return {
        dir: {
            input: "src",
            output: "dist"
        },
        markdownTemplateEngine: 'njk',
        dataTemplateEngine: 'njk',
        htmlTemplateEngine: 'njk',
    }
  };

Someone can explain to me why is this happening, and how can I solve this? Thanks

  • Not an issue I think, but Eleventy looks in _includes for layouts. Your file is _includes/layouts/base.html. When you specify the layout in your template, are you doing something like: layouts/base ? – Raymond Camden Sep 10 '21 at 14:27
  • I'm not able to reproduce this myself. Maybe share your template calling it? – Raymond Camden Sep 10 '21 at 14:33
  • Hello Raymond, I've just updated this question with the new code. As you'll notice, I'm defining data in a 'base' layout. That *data* will be used by a partial called 'top-nav'. By the moment, I've moved this information to _data where I can access this information at global, but this is not ideal. I really wanted to be as a front matter in my base.html layout. – Lucas David Ferrero Sep 10 '21 at 16:13
  • I think front matter is parsed by Eleventy, not Nunjucks, which is why you are seeing it like that. – Raymond Camden Sep 10 '21 at 19:59

Front-matter data is only available in layout files that are directly referenced by pages with the layout: front matter key, not with Nunjucks {% extends %}. Front matter data in directly referenced layout files are merged with other data as part of 11ty's data cascade. (11ty docs: front matter in layouts)

For example:

<!-- index.md -->
---
layout: layouts/content
---
# some content here

{# layouts/base.njk #}
---
hello: "world"
---
{# ^ the above will be printed as plain text and isn't available #}

{# layouts/content.njk #}
---
someKey: "something"
---
{% extends "layouts/base.njk" %}

{{ someKey }}
{# ^ this will render "something" as expected #}

This is likely because {% extends %} is a feature of Nunjucks, and Eleventy is not aware of which other Nunjucks files are being referenced.

For your situation, you have a couple of options. First, you could place your front matter data in layouts/home, since that's what you're referencing in your index.md. Another option is to just use Nunjuck's set tag.

{% set links = [
    {
        "icon": "mail_outline",
        "href": "https://google.com"
    }
] %}

{% for link in links %}
    {{ link.icon }}
    {{ link.href }}
{% endfor %}
