markdown-it-table-of-contents

A table of contents plugin for Markdown-it. Based on https://github.com/samchrisinger/markdown-it-toc but simpler, a bit more customizable and with a default slugifier that matches that of https://www.npmjs.com/package/markdown-it-anchor.

Usage

var MarkdownIt = require("markdown-it");
var md = new MarkdownIt();

md.use(require("markdown-it-anchor")); // Optional, but makes sense as you really want to link to something
md.use(require("markdown-it-table-of-contents"));

Then add [[toc]] where you want the table of contents to be added in your markdown.

Example markdown

This markdown:

# Heading

[[toc]]

## Sub heading 1
Some nice text

## Sub heading 2
Some even nicer text

... would render this HTML using the default options specified in "usage" above:

<h1 id="heading">Heading</h1>

<div class="table-of-contents">
  <ul>
    <li><a href="#heading">Heading</a>
      <ul>
        <li><a href="#sub-heading-1">Sub heading 1</a></li>
        <li><a href="#sub-heading-2">Sub heading 2</a></li>
      </ul>
    </li>
  </ul>
</div>

<h2 id="sub-heading-1">Sub heading 1</h2>
<p>Some nice text</p>

<h2 id="sub-heading-2">Sub heading 2</h2>
<p>Some even nicer text</p>
