markdown-it-title npm version

Extract title during markdown-it parsing.

Overview

This plugin is useful if you want to write plain markdown files, e.g. without YAML front matter, and want to extract the document title to populate a HTML <title> tag, Open Graph and so on.

Additionally, markdown-it-title supports extracting the contents of the first paragraphs if you want to use them as meta description, post excerpt and so forth.

Usage

const opts = {
  level: 1,
  excerpt: 2
}

const md = require('markdown-it')()
  .use(require('markdown-it-title'), opts)

const env = {}

md.render(`# [Hello](#hello), *world*!

This is the **first** paragraph.

## Hi, I'm a title

Another one.

And another one.
`, env)

env.title === 'Hello, world!'
env.excerpt[0] === 'This is the first paragraph.'
env.excerpt[1] === 'Another one.'

The opts object can contain:

Name Description Default
level Heading level to look for the title. Use 0 to take whichever heading comes first. 1
excerpt Number of paragraphs to extract from the beginning of the document to be used as page excerpt. 0

Setting level to 1 (the default) will extract the contents of the first <h1> to env.title. If set to 0, markdown-it-title will take the first heading it encounters.

Also, the first excerpt paragraphs will be extracted in the env.excerpt array (not enabled by default).

Both title and excerpt text won't include any markup.
