<h2>Summary</h2>

<div class="markdown-from-sourecode">
  <p><p>InjectedComponent makes it easy to include dynamically registered
components inside of your React render method. Rather than explicitly render
a component, such as a <code>&lt;Composer&gt;</code>, you can use InjectedComponent:</p>
<pre><code class="lang-coffee"><span class="hljs-tag">&lt;<span class="hljs-title">InjectedComponent</span> <span class="hljs-attribute">matching</span>=<span class="hljs-value">{role:"Composer"}</span> <span class="hljs-attribute">exposedProps</span>=<span class="hljs-value">{draftClientId:123}</span> /&gt;</span>
</code></pre>
<p>InjectedComponent will look up the component registered with that role in the
<a href='componentregistry.html'>ComponentRegistry</a> and render it, passing the exposedProps (<code>draftClientId={123}</code>) along.</p>
<p>InjectedComponent monitors the ComponentRegistry for changes. If a new component
is registered that matches the descriptor you provide, InjectedComponent will refresh.</p>
<p>If no matching component is found, the InjectedComponent renders an empty div.</p>
</p>

                <p>Pass an <a href='https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/object'>Object</a> with ComponentRegistry descriptors.
