A Markdown blog post

Tags File

Use the tags plugin option to configure the path of a YAML tags file.

By convention, the plugin will look for a tags.yml file at the root of your content folder(s).

This file can contain a list of predefined tags. You can reference these tags by their keys in Markdown files thanks to the tags front matter.

Keeping tags consistent

Using a tags file, you can ensure that your tags usage is consistent across your plugin content set. Use the onInlineTags: 'throw' plugin option to enforce this consistency and prevent usage of inline tags declared on the fly.

Types

The YAML content of the provided tags file should respect the following shape:

type Tag = {
  label?: string; // Tag display label
  permalink?: string; // Tag URL pathname segment
  description?: string; // Tag description displayed in the tag page
};

type TagsFileInput = Record<string, Partial<Tag> | null>;

Example

tags.yml

releases:
  label: 'Product releases'
  permalink: '/product-releases'
  description: 'Content related to product releases.'

# A partial tag definition is also valid
announcements:
  label: 'Announcements'

# An empty tag definition is also valid
# Other attributes will be inferred from the key
emptyTag:

content.md

---
tags: [releases, announcements, emptyTag]
---

# Title

Content

Authors File

Use the authors plugin option to configure the path of a YAML authors file.

By convention, the plugin will look for a authors.yml file at the root of your blog content folder(s).

This file can contain a list of predefined global blog authors. You can reference these authors by their keys in Markdown files thanks to the authors front matter.

Types

The YAML content of the provided authors file should respect the following shape:

type AuthorsMapInput = {
  [authorKey: string]: AuthorInput;
};

type AuthorInput = {
  name?: string;
  title?: string;
  description?: string;
  imageURL?: string;
  url?: string;
  email?: string;
  page?: boolean | {permalink: string};
  socials?: Record<string, string>;
  [customAuthorAttribute: string]: unknown;
};

Example

tags.yml

slorber:
  name: Sébastien Lorber
  title: Docusaurus maintainer
  url: https://sebastienlorber.com
  image_url: https://github.com/slorber.png
  page: true
  socials:

jmarcey:
  name: Joel Marcey
  title: Co-creator of Docusaurus 1

  image_url: https://github.com/JoelMarcey.png
  email: [email protected]
