<p><code>React</code> is the entry point to the React framework. If you're using one of the prebuilt packages it's available as a global; if you're using CommonJS modules you can <code>require()</code> it.</p>
|
|
<h3 id="react.dom" class="anchor"><a href="#react.dom">React.DOM</a></h3>
|
|
<p><code>React.DOM</code> provides all of the standard HTML tags needed to build a React app. You generally don't use it directly; instead, just include it as part of the <code>/** @jsx React.DOM */</code> docblock.</p>

|
|
<p>Creates a component given a specification. A component implements a <code>render</code> method which returns <strong>one single</strong> child. That child may have an arbitrarily deep child structure. One thing that makes components different than standard prototypal classes is that you don't need to call new on them. They are convenience wrappers that construct backing instances (via new) for you.</p>
|
|
|
|
<p>For more information about the specification object, see <a href="component-specs.html">Component Specs and Lifecycle</a>.</p>

<p>If the React component was previously rendered into <code>container</code>, this will perform an update on it and only mutate the DOM as necessary to reflect the latest React component.</p>

|

<p>Note:</p>

|
|
</code></pre></div>
|
|
<p>Render a component to its initial HTML. This should only be used on the server. React will call <code>callback</code> with an HTML string when the markup is ready. You can use this method to can generate HTML on the server and send the markup down on the initial request for faster page loads and to allow search engines to crawl your pages for SEO purposes.</p>
|
|
|
|
<p>If you call <code>React.renderComponent()</code> on a node that already has this server-rendered markup, React will preserve it and only attach event handlers, allowing you to have a very performant first-load experience.</p>
