Renders Markdown as pure React components.
Demo available at http://rexxars.github.io/react-markdown/
npm install --save react-markdown
var React = require('react');
var ReactDOM = require('react-dom');
var ReactMarkdown = require('react-markdown');
var input = '# This is a header\n\nAnd this is a paragraph';
ReactDOM.render(
<ReactMarkdown source={input} />,
document.getElementById('container')
);
If you are using Webpack, you need to enable a JSON-loader. To do so, first npm install --save json-loader
, then add the loader to your webpack config:
{
module: {
loaders: [{
test: /\.json$/,
loader: 'json'
}]
}
}
If you either set escapeHtml
or skipHtml
to true
, this component does not use dangerouslySetInnerHTML
at all - this is a Good Thing™.
source
- string The Markdown source to parse (required)className
- string Class name of the container element (default:''
).containerTagName
- string Tag name for the container element, since Markdown can have many root-level elements, the component need to wrap them in something (default:div
).containerProps
- object An object containing custom element props to put on the container element such asid
andhtmlFor
.childBefore
- object A single child object that is rendered before the markdown source but within the container elementchildAfter
- object A single child object that is rendered after the markdown source but within the container elementescapeHtml
- boolean Setting totrue
will escape HTML blocks, rendering plain text instead of inserting the blocks as raw HTML (default:false
).skipHtml
- boolean Setting totrue
will skip inlined and blocks of HTML (default:false
).sourcePos
- boolean Setting totrue
will adddata-sourcepos
attributes to all elements, indicating where in the markdown source they were rendered from (default:false
).softBreak
- string Setting tobr
will create<br>
tags instead of newlines (default:\n
).allowedTypes
- array Defines which types of nodes should be allowed (rendered). (default: all types).disallowedTypes
- array Defines which types of nodes should be disallowed (not rendered). (default: none).unwrapDisallowed
- boolean Setting totrue
will try to extract/unwrap the children of disallowed nodes. For instance, if disallowingStrong
, the default behaviour is to simply skip the text within the strong altogether, while the behaviour some might want is to simply have the text returned without the strong wrapping it. (default:false
)allowNode
- function Function execute if in order to determine if the node should be allowed. Ran prior to checkingallowedTypes
/disallowedTypes
. Returning a truthy value will allow the node to be included. Note that if this function returnstrue
and the type is not inallowedTypes
(or specified as adisallowedType
), it won't be included. The function will get a single object argument (node
), which includes the following properties:type
- string The type of node - same ones accepted inallowedTypes
anddisallowedTypes
renderer
- string The resolved renderer for this nodeprops
- object Properties for this nodechildren
- array Array of children
renderers
- object An object where the keys represent the node type and the value is a React component. The object is merged with the default renderers. The props passed to the component varies based on the type of node. See the type renderer options ofcommonmark-react-renderer
for more details.transformLinkUri
- function|null Function that gets called for each encountered link with a single argument -uri
. The returned value is used in place of the original. The default link URI transformer acts as an XSS-filter, neutralizing things likejavascript:
,vbscript:
andfile:
protocols. If you specify a custom function, this default filter won't be called, but you can access it asrequire('react-markdown').uriTransformer
. If you want to disable the default transformer, passnull
to this option.
The possible types of elements that can be allowed/disallowed are:
HtmlInline
- Inline HTMLHtmlBlock
- Block of HTMLText
- Text nodes (inside of paragraphs, list items etc)Paragraph
- Paragraph nodes (<p>
)Heading
- Headers (<h1>
,<h2>
etc)Softbreak
- NewlinesHardbreak
- Hard line breaks (<br>
)Link
- Link nodes (<a>
)Image
- Image nodes (<img>
)Emph
- Emphasis nodes (<em>
)Code
- Inline code nodes (<code>
)CodeBlock
- Blocks of code (<code>
)BlockQuote
- Block quotes (<blockquote>
)List
- List nodes (<ol>
,<ul>
)Item
- List item nodes (<li>
)Strong
- Strong/bold nodes (<strong>
)ThematicBreak
- Horizontal rule nodes (<hr>
)
Note: Disallowing a node will also prevent the rendering of any children of that node, unless the unwrapDisallowed
option is set to true
. Eg, disallowing a paragraph will not render it's children text nodes.
