React goes web component – Use custom tags to place react components directly in html.

Install

Download

From Github, NPM:

$ npm install --save react-mount

or Bower:

$ bower install react-mount

Include

With AMD or Browserify:

var mount = require("react-mount");

Vanilla JS:

<script src="path/to/file/react-mount.js"></script>
<script>
	var mount = React.mount;
</script>

Basic Usage

<body>
	<react-component />
	
	<!-- Dependencies -->
	<script src="react.js"></script>
	<script src="JSXTransformer.js"></script>
	<script src="react-mount.js"></script>

	<script>
		// React component
		var ReactComponent = React.createClass({
			render: function() {
				return React.createElement("i", null, "Component mounted. React is running.")
			}
		});
		
		// Mount component
		React.mount({
			"react-component" : ReactComponent
		});
	</script>
</body>

Output

Component mounted. React is running.

Tag Content

Content of custom tags can be written in Html or JSX.

<translucent-component>
	<p style="text-transform: uppercase">
		Html is transformed to <span style="font-weight:bold">JSX</span> for you.
	</p>
</translucent-component>

The content of a custom tag is available in the mounted react component with this.props.children:

var translucentComponent = React.createClass({
	render: function() {
		return (
			{this.props.children}
		);
	}
});

Output

HTML IS TRANSFORMED TO JSX FOR YOU.

Nested Components

Custom component tags can be nested as long as all used components are properly mounted:

<translucent-component>
	<react-component />
</translucent-component>

mount({
	"react-component"		:	ReactComponent,
	"translucent-component"	:	TranslucentComponent
});

Output

Component mounted. React is running.

Expressions and Properties

{expressions} can be used within a tag and are executed properly. Within {expressions} properties from the global namespace window can be accessed. However to keep the global namespace clear, properties can also be defined in the opts object passed to the mount function:

window.paragraph = "Component mounted. React is running.";

React.mount({
	"translucent-component" : ReactComponent
},
{
	props : {
		list : [
			  "Item 1",
			  "Item 2",
			  "Item 3"
		],
		attribute : "myAttribute"
	}
});

These properties are avaliable within expressions as props.key:

{window.paragraph} // "Component mounted. React is running."

{props.list.length <= 3 ? "Yes!" : "No!"} // Yes!

// shortcut for simple reference (props. is appended for you)
{attribute} 	// "myAttribute"


<translucent-component attribute={attribute}>
	<p>{window.paragraph}</p>
	<p>Less than four list items? </b>{props.list.length <= 3 ? "Yes!" : "No!"}</b></p>
	<ul>
		{props.list.map(function(value, i){
			return <li key={i} >{value}</li>;
		})}
	</ul>
</translucent-component>

Within react component: this.props.attribute === "myAttribute" this.props.children contains ..., ... and <ul>...</ul>.

Output

Component mounted. React is running.

Less than four list items? Yes!

Item 1
Item 2
Item 3

Case-Sensitive Attributes

Html is case insensitiv and transforms everything outside of strings to lowercase. React props however are case sensitive and therefore some components require correctly capitalized attributes.

There are two ways to preserve the capitalization of attributes:

A) Per component

mount({
	"react-component" : ["camelCaseAttribute", "anotherAttribute", ReactComponent]
});

B) For all components

mount({
	"react-component" : ReactComponent
}, {
	preserveAttributes : ["camelCaseAttribute", "anotherAttribute"]
});

In both cases you can now savely use the preserved attributes:

<react-component camelCaseAttribute="preserved attribute" notPreservedAttribute="not preserved" />

Within react component: this.props.camelCaseAttribute === "preserved attribute" but this.props.notPreservedAttribute === undefined this.props.notpreservedattribute === "not preserved"

HTML Comments

Html comments do not affect the output of the rendering in any way. They can be used to mask unrendered content before react kicks in.

<translucent-component>
	<!--
		<i>{paragraph}</i>
	-->
</translucent-component>

this.props.children still contains value.

Output

value

Tipp: Use JSX style {/* comments */} for actual comments.

API

`mount( tags [, opts] );`

tags `required`

Type Object
Object with tags and their corresponding components to be mounted.
{
	"tag-name"	: 	ReactComponent,
	"tag-Name"	: 	ReactComponent,
  ...
	"TAG-NAME"	: 	["camelCaseAttribute", ReactComponent],
	...
	[tag]		: 	[component | Array]
}
Tag names are case insensitive. All the above definitions would do the same / the first component would be mounted to all of the tags.
Optional: Instead of a React component, an array with case-sensitive attributes can be defined. The last item of the array is the react component to be mounted. See: Case-Sensitive Attributes
Tipp: Lower case tag names containing at least one dash are/will be valid html. See: http://w3c.github.io/webcomponents/spec/custom/#concepts

opts `optional`

Type Object
Available options for react-mount:
{
	"context"				: 	[HTMLElement],
	"props"					: 	{...},
	"preserveAttributes"	: 	[...],
	"wrapper"				: 	[HTMLElement]
}
context
Type HTMLElement Default document.body
Only tags within this element will be mounted.
props
Type Object
key:value pairs of Properties. Properties can be used in {expressions} within the mounted tags.
See: Expressions and Properties
preserveAttributes
Type Array
Array of case-sensitive attributes to preserve capitatization.
See: Case-Sensitive Attributes
wrapper
Type HTMLElement Default document.createElement("div")
Define a custom wrapper to mount react components into.
