breakdance

Breakdance is a node.js library for converting HTML to markdown. Highly pluggable, flexible and easy to use. It's time for your markup to get down.

Breakdance is a node.js library for converting HTML to markdown. You can use breakdance to:

• Migrate HTML blog posts to markdown
• Convert wiki pages to markdown
• Convert HTML documentation to markdown
• Convert HTML presentations or slide decks to markdown
• Convert busy web pages into readable markdown documents.

Visit breakdance.io for detailed documentation, examples, recipes, and advice on authoring and finding plugins.

Why should I use breakdance?

Breakdance uses cheerio to parse HTML, and snapdragon for rendering, which provides granular control over the entire conversion process in a way that is easy to understand, reason about, and customize. If you see something you don't like, it's easy to change!

Generates well-formatted markdown

• Comprehensive HTML tag coverage.
• Granular control over every HTML element and attributes
• Even converts HTML tables to markdown!

Extremely pluggable

Every part of the conversion is customizable:

• options are available for customizing output of any HTML tag if you don't like the defaults
• plugins are easy to write if you'd like to share your customizations with the world

HTML-to-markdown example

Tables

The following HTML table from bootstrap's docs:

<h2 id=tables-hover-rows>Hover rows</h2>
<p>Add <code>.table-hover</code> to enable a hover state on table rows within a <code>&lt;tbody&gt;</code>.</p>
<div class=bs-example data-example-id=hoverable-table>
  <table class="table table-hover">
    <thead>
      <tr>
        <th>#</th>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Username</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <th scope=row>1</th>
        <td>Mark</td>
        <td>Otto</td>
        <td>@mdo</td>
      </tr>
      <tr>
        <th scope=row>2</th>
        <td>Jacob</td>
        <td>Thornton</td>
        <td>@fat</td>
      </tr>
      <tr>
        <th scope=row>3</th>
        <td>Larry</td>
        <td>the Bird</td>
        <td>@twitter</td>
      </tr>
    </tbody>
  </table>
</div>

Would render to the following markdown:

## Hover rows

Add `.table-hover` to enable a hover state on table rows within a `<tbody>`.

| # | First Name | Last Name | Username |
| --- | --- | --- | --- |
| 1 | Mark | Otto | @mdo |
| 2 | Jacob | Thornton | @fat |
| 3 | Larry | the Bird | @twitter |

See the documentation for more examples.

3.0.0 - 2017-05-12

Removed

• CLI was externalized to [breakdance-cli][]

2.0.0 - 2017-04-25

Changed

• <b>: now renders as **bold**, same as <strong> tags
• <i>: now renders as _italics_, same as <em> tags

1.1.0 - 2017-04-21

Fixed

• <code>: improvements to whitespace handling
• <code>: no longer renders empty tags
• <p>: normalize Unicode U+00A0 non-breaking spaces to "normal" Unicode U+0020 spaces. Non-breaking spaces are useful in HTML, but cause flow problems in markdown.

Added

1.0.0 - 2017-03-12

Added

• Adds support for <base>, closes issue #3

Changed

• Changed the CLI command from tomd to either br. As a fallback, you can also use breakdance if there is a conflict. The CLI has not yet been documented, so hopefully this doesn't cause any issues for anyone.

0.1.5

Fixed

• An extra trailing newline was being added on <code> tags

Added

• Adds keepEmpty option, to selective keep empty tags that are omitted by built-in omitEmpty tags
• Adds documentation for omit, pick and omitEmpty and keepEmpty options

Changed

• Externalized utils.js to breakdance-util, to allow plugin authors to use the same utilities as breakdance, for consistency.

0.1.4

Fixed

• Better whitespace handling in table, a and dl tags

Added

• Adds documentation for url option

[0.1.0]

First release.
