A markdown parser with renderer feature.


A markdown parser and compiler. Forked from marked for impatience.

UPDATE: marked has merged renderer feature, markit will be my own markdown parser for new features.

Install with npm:

$ npm install markit --save

Install with component(1):

$ component install lepture/markit

Minimal usage:

var marked = require('markit');
console.log(marked('I am using __markdown__.'));
// Outputs: <p>I am using <strong>markdown</strong>.</p> 

Example setting options with default values:

var marked = require('marked');
  renderer: new marked.Renderer(),
  gfm: true,
  tables: true,
  breaks: false,
  pedantic: false,
  sanitize: true,
  smartLists: true,
  smartypants: false
console.log(marked('I am using __markdown__.'));

Type: string

String of markdown source to be compiled.

Type: object

Hash of options. Can also be set using the marked.setOptions method as seen above.

Type: function

Function called when the markdownString has been fully parsed when using async highlighting. If the options argument is omitted, this can be used as the second argument.

Type: function

A function to highlight code blocks. The first example below uses async highlighting with [node-pygmentize-bundled][pygmentize], and the second is a synchronous example using [highlight.js][highlight]:

var marked = require('marked');
var markdownString = '```js\n console.log("hello"); \n```';
// Async highlighting with pygmentize-bundled 
  highlight: function (code, lang, callback) {
    require('pygmentize-bundled')({ lang: lang, format: 'html' }, code, function (err, result) {
      callback(err, result.toString());
// Using async version of marked 
marked(markdownString, function (err, content) {
  if (err) throw err;
// Synchronous highlighting with highlight.js 
  highlight: function (code) {
    return require('highlight.js').highlightAuto(code).value;


Type: string

The section of code to pass to the highlighter.


Type: string

The programming language specified in the code block.


Type: function

The callback function to call when using an async highlighter.

Type: object Default: new Renderer()

An object containing functions to render tokens to HTML.

The renderer option allows you to render tokens in a custom manor. Here is an example of overriding the default heading token rendering by adding an embedded anchor tag like on GitHub:

var marked = require('marked');
var renderer = new marked.Renderer();
renderer.heading = function (text, level) {
  var escapedText = text.toLowerCase().replace(/[^\w]+/g, '-');
  return '<h' + level + '><a name="' +
                escapedText +
                 '" class="anchor" href="#' +
                 escapedText +
                 '"><span class="header-link"></span></a>' +
                  text + '</h' + level + '>';
console.log(marked('# heading+', { renderer: renderer }));

This code will output the following HTML:

  <a name="heading-" class="anchor" href="#heading-">
    <span class="header-link"></span>
  • code(string code, string language)
  • blockquote(string quote)
  • html(string html)
  • heading(string text, number level)
  • hr()
  • list(string body, boolean ordered)
  • listitem(string text)
  • paragraph(string text)
  • table(string header, string body)
  • tablerow(string content)
  • tablecell(string content, object flags)

flags has the following properties:

    header: true || false,
    align: 'center' || 'left' || 'right'
  • strong(string text)
  • em(string text)
  • codespan(string code)
  • br()
  • del(string text)
  • link(string href, string title, string text)
  • image(string href, string title, string text)

Type: boolean Default: true

Enable [GitHub flavored markdown][gfm].

Type: boolean Default: true

Enable GFM [tables][tables]. This option requires the gfm option to be true.

Type: boolean Default: false

Enable GFM [line breaks][breaks]. This option requires the gfm option to be true.

Type: boolean Default: false

Conform to obscure parts of as much as possible. Don't fix any of the original markdown bugs or poor behavior.

Type: boolean Default: false

Sanitize the output. Ignore any HTML that has been input.

Type: boolean Default: true

Use smarter list behavior than the original markdown. May eventually be default with the old behavior moved into pedantic.

Type: boolean Default: false

Use "smart" typograhic punctuation for things like quotes and dashes.

You also have direct access to the lexer and parser if you so desire.

var tokens = marked.lexer(text, options);
var lexer = new marked.Lexer(options);
var tokens = lexer.lex(text);

You can create a standalone script with:

$ make standalone
