Content

Frontmatter Schema

Every content file starts with YAML frontmatter:

---
layout: layouts/page.njk    # Required
title: Page Title           # Required
description: Meta desc      # Recommended
date: 2026-01-08           # Recommended
draft: false               # Optional
tags: [tag1, tag2]         # Optional
image: /path/to/og.jpg     # Optional
---

Layout Options

Layout	Use Case
layouts/base.njk	Raw HTML shell, rarely used directly
layouts/page.njk	Standard content pages
layouts/docs.njk	Documentation with sidebar TOC
layouts/post.njk	Blog posts (if using blog)

Markdown Content

Markdown files are processed with Nunjucks, so you can use template features:

# {{ title }}

Published on {{ date | readableDate }}

## Section Heading

Regular markdown content here.

{% include "partials/cta.njk" %}

Collections

Define collections in eleventy.config.js:

eleventyConfig.addCollection("posts", function (collectionApi) {
  return collectionApi
    .getFilteredByGlob("src/content/posts/**/*.md")
    .filter((item) => !item.data.draft)
    .sort((a, b) => b.date - a.date);
});

Data Cascade

Eleventy merges data from multiple sources (highest priority first):

1. Frontmatter in the template
2. Template-specific data file (page.11tydata.js)
3. Directory data file (posts.json)
4. Global data files (_data/*.json)
