__Note.__ CommonMark version runs with [simplified link normalizers](https://github.com/markdown-it/markdown-it/blob/master/benchmark/implementations/current-commonmark/index.js)
for more "honest" compare. Difference is ~ 1.5x.
As you can see, `markdown-it` doesn't pay with speed for it's flexibility.
Because it's written in monomorphyc style and uses JIT inline caches effectively.
Slowdown of "full" version caused by additional features, not available in
other implementations.

> Markdown parser done right. Fast and easy to extend.
__[Live demo](https://markdown-it.github.io)__
__v4.+ changed internals! Plugins need update. See [migration details](https://github.com/markdown-it/markdown-it/blob/master/docs/4.0_migration.md)__
- Supports the CommonMark spec + syntax extensions + sugar (URL autolinking, typographer).
- Configurable syntax! You can add new rules and even replace existing ones.
- High speed!
- Community-written __[plugins](https://www.npmjs.org/browse/keyword/markdown-it-plugin)__ and [other packages](https://www.npmjs.org/browse/keyword/markdown-it) on npm.

## Install
**node.js** & **bower**:
```bash
npm install markdown-it --save
bower install markdown-it --save
```
**browser (CDN):**
- [jsDeliver CDN](http://www.jsdelivr.com/#!markdown-it "jsDelivr CDN")
- [cdnjs.com CDN](https://cdnjs.com/libraries/markdown-it "cdnjs.com")
## Usage examples
See also:
- __[API documentation](https://markdown-it.github.io/markdown-it/)__ - for more
info and examples.
- [Development info](https://github.com/markdown-it/markdown-it/tree/master/docs) -
for plugins writers.
### Simple
```js
// node.js, "classic" way:
var MarkdownIt = require('markdown-it'),
md = new MarkdownIt();
var result = md.render('# markdown-it rulezz!');
// node.js, the same, but with sugar:
var md = require('markdown-it')();
var result = md.render('# markdown-it rulezz!');
// browser without AMD, added to "window" on script load
// Note, there are no dash.
var md = window.markdownit();
var result = md.render('# markdown-it rulezz!');
```
Single line rendering, without paragraph wrap:
```js
var md = require('markdown-it')();
var result = md.renderInline('__markdown-it__ rulezz!');
```
### Init with presets and options
(*) preset define combination of active rules and options. Can be
`"commonmark"`, `"zero"` or `"default"` (if skipped). See
[API docs](https://markdown-it.github.io/markdown-it/#MarkdownIt.new) for more details.
```js
// commonmark mode
var md = require('markdown-it')('commonmark');
// default mode
var md = require('markdown-it')();
// enable everything
var md = require('markdown-it')({
html: true,
linkify: true,
typographer: true
});
// full options list (defaults)
var md = require('markdown-it')({
html: false, // Enable HTML tags in source
xhtmlOut: false, // Use '/' to close single tags (<br />).
// This is only for full CommonMark compatibility.
breaks: false, // Convert '\n' in paragraphs into <br>
langPrefix: 'language-', // CSS language prefix for fenced blocks. Can be
// useful for external highlighters.
linkify: false, // Autoconvert URL-like text to links
// Enable some language-neutral replacement + quotes beautification
typographer: false,
// Double + single quotes replacement pairs, when typographer enabled,
// and smartquotes on. Set doubles to '«»' for Russian, '„“' for German.
quotes: '“”‘’',
// Highlighter function. Should return escaped HTML,
// or '' if the source string is not changed and should be escaped externaly.
highlight: function (/*str, lang*/) { return ''; }
});
```
### Plugins load
```js
var md = require('markdown-it')()
.use(plugin1)
.use(plugin2, opts, ...)
.use(plugin3);
```
### Syntax highlighting
Apply syntax highlighting to fenced code blocks with the `highlight` option:
```js
var hljs = require('highlight.js') // https://highlightjs.org/
// Actual default values
var md = require('markdown-it')({
highlight: function (str, lang) {
if (lang && hljs.getLanguage(lang)) {
try {
return hljs.highlight(lang, str).value;
} catch (__) {}
}
try {
return hljs.highlightAuto(str).value;
} catch (__) {}
return ''; // use external default escaping
}
});
```
## API
__[API documentation](https://markdown-it.github.io/markdown-it/)__
If you are going to write plugins - take a look at
[Development info](https://github.com/markdown-it/markdown-it/tree/master/docs).
## Syntax extensions
Embedded (enabled by default):
- [Tables](https://help.github.com/articles/github-flavored-markdown/#tables) (GFM)
- [Strikethrough](https://help.github.com/articles/github-flavored-markdown/#strikethrough) (GFM)
Via plugins:
- [subscript](https://github.com/markdown-it/markdown-it-sub)
- [superscript](https://github.com/markdown-it/markdown-it-sup)
- [footnote](https://github.com/markdown-it/markdown-it-footnote)
- [definition list](https://github.com/markdown-it/markdown-it-deflist)
- [abbreviation](https://github.com/markdown-it/markdown-it-abbr)
- [emoji](https://github.com/markdown-it/markdown-it-emoji)
- [custom container](https://github.com/markdown-it/markdown-it-container)

- [mark](https://github.com/markdown-it/markdown-it-mark)
- ... and [others](https://www.npmjs.org/browse/keyword/markdown-it-plugin)
### Manage rules
By default all rules are enabled, but can be restricted by options. On plugin
load all it's rules are enabled automatically.
```js
// Activate/deactivate rules, with curring
var md = require('markdown-it')()
.disable([ 'link', 'image' ])
.enable([ 'link' ])
.enable('image');
// Enable everything
md = require('markdown-it')('full', {
html: true,
linkify: true,
typographer: true,
});
```
## Benchmark
Here is result of CommonMark spec parse at Core i5 2.4 GHz (i5-4258U):
```bash
$ benchmark/benchmark.js spec
Selected samples: (1 of 27)
> spec
Sample: spec.txt (110610 bytes)
> commonmark-reference x 68.63 ops/sec ±6.53% (72 runs sampled)
> current x 79.62 ops/sec ±3.22% (80 runs sampled)
> current-commonmark x 103 ops/sec ±1.10% (76 runs sampled)
> marked-0.3.2 x 23.14 ops/sec ±1.66% (42 runs sampled)
```
As you can see, `markdown-it` doesn't pay with speed for it's flexibility.
Because it's written in monomorphyc style and uses JIT inline caches effectively.

_markdown-it_ is the result of the decision of the authors who contributed to
99% of the _Remarkable_ code to move to a project with the same authorship but
new leadership (Vitaly and Alex). It's not a fork.
## References / Thanks
Big thanks to [John MacFarlane](https://github.com/jgm) for his work on the
CommonMark spec and reference implementations. His work saved us a lot of time
during this project's development.
