Usage

Once installed, you can start transforming HTML into Markdown with ease! Here’s how:

var TurndownService = require('turndown');
var turndownService = new TurndownService();
var markdown = turndownService.turndown('
Hello world!
');

Turndown also accepts DOM nodes as input:

var markdown = turndownService.turndown(document.getElementById('content'));

Options

You can customize your Turndown instance with several options:

• headingStyle: Set to “setext” or “atx” (default: setext)
• hr: Define any thematic break (default: * * *)
• bulletListMarker: Choose from “-“, “+”, or “*” (default: *)
• codeBlockStyle: Select between “indented” or “fenced” (default: indented)
• …and many more!

Advanced Features

To extend Turndown’s functionality, you can add rules, keep, or remove specific elements from conversion, and use plugins:

turndownService.addRule('strikethrough', {
  filter: ['del', 's', 'strike'],
  replacement: function(content) {
    return '~' + content + '~';
  }
});

This example adds support for strikethrough formatting!

Analogy: A Chef Transforming Ingredients
