@dv0vd/vuepress-auto-description

Automatically generate meta description for VuePress 2 pages from your Markdown content.

Features

• Auto-generate meta description from first paragraph(s)
• Paragraph-safe trimming to a configurable maximum length

Installation

npm install @dv0vd/vuepress-auto-description

How It Works

1. Check existing description: If page.frontmatter.description is already set, the plugin does nothing and preserves the existing description.
2. Extract paragraphs: The plugin parses the rendered HTML (page.contentRendered) and extracts all <p> elements.
3. Plain text: HTML tags are removed, and whitespace is normalized. Empty paragraphs are ignored.
4. Trim to max length:
   • The plugin does not cut text in the middle of a word.
   • Paragraphs are added sequentially until the total length reaches maxDescriptionLength.
   • Because whole paragraphs are added, the final length may slightly exceed the limit to avoid cutting words in half.
5. Save description: The final text is assigned to page.frontmatter.description.

Usage

import autoDescriptionPlugin from '@dv0vd/vuepress-auto-description';

export default {
  plugins: [
    autoDescriptionPlugin(160),
  ],
};
