@mdit-vue/plugin-headers

A markdown-it plugin to get markdown headers.

• Extracts all headers info into markdown-it env.headers.

Install

npm i @mdit-vue/plugin-headers

Usage

import { headersPlugin } from '@mdit-vue/plugin-headers';
import type { MarkdownItEnv } from '@mdit-vue/types';
import MarkdownIt from 'markdown-it';

const md = MarkdownIt({ html: true }).use(headersPlugin, {
  // options
});
const env: MarkdownItEnv = {};

const rendered = md.render(
  `\
# h1
## h2
### h3
`,
  env,
);

console.log(env.headers);

Options

format

• Type: (str: string) => string

• Details:

  A function for formatting header title.

level

• Type: number[]

• Default: [2, 3]

• Details:

  Heading level that going to be extracted.

  When using this plugin with markdown-it-anchor (recommended), this option should be a subset of markdown-it-anchor's level option to ensure the header slugs are existed.

shouldAllowNested

• Type: boolean

• Default: false

• Details:

  Should allow headers inside nested blocks or not.

  If set to true, headers inside blockquote, list, etc. would also be extracted.

slugify

• Type: (str: string) => string

• Default: slugify from @mdit-vue/shared

• Details:

  A custom slugification function.

  The default slugify function comes from @mdit-vue/shared package.

  When using this plugin with markdown-it-anchor (recommended), this option will be ignored because the id of the headings have already been determined by markdown-it-anchor's slugify option.
