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]
