<p>The XML syntax inside of JavaScript is called JSX; check out the <a href="/react/docs/jsx-in-depth.html">JSX syntax</a> to learn more about it. In order to translate it to vanilla JavaScript we use <code><script type="text/jsx"></code> and include <code>JSXTransformer.js</code> to actually perform the transformation in the browser.</p>
|
|
<h3><a class="anchor" name="separate-file"></a>Separate File <a class="hash-link" href="#separate-file">#</a></h3>
|

<p>Your React JSX file can live in a separate file. Create the following <code>src/helloworld.js</code>.</p>

<p>Then reference it from <code>helloworld.html</code>:</p>

<div class="highlight"><pre><code class="html language-html" data-lang="html"><span class="nt"><script </span><span class="na">type=</span><span class="s">"text/jsx"</span> <span class="na">src=</span><span class="s">"src/helloworld.js"</span><span class="nt">></script></span>

</code></pre></div><h3><a class="anchor" name="offline-transform"></a>Offline Transform <a class="hash-link" href="#offline-transform">#</a></h3>
|

<p>First install the command-line tools (requires <a href="http://npmjs.org/">npm</a>):</p>
|
|
<div class="highlight"><pre><code class="text language-text" data-lang="text">npm install -g react-tools
|

|

<p>Then, translate your <code>src/helloworld.js</code> file to plain JavaScript:</p>

<div class="highlight"><pre><code class="text language-text" data-lang="text">jsx --watch src/ build/
|
|
</code></pre></div>

<p>The file <code>build/helloworld.js</code> is autogenerated whenever you make a change.</p>

<blockquote>
|
|
<p>Note:</p>
|
|
|
|
<p>The comment parser is very strict right now, in order for it to pick up the <code>@jsx</code> modifier, two conditions are required. The <code>@jsx</code> comment block must be the first comment on the file. The comment must start with <code>/**</code> (<code>/*</code> and <code>//</code> will not work). If the parser can't find the <code>@jsx</code> comment, it will output the file without transforming it.</p>

<p>Update your HTML file as below:</p>

<p>If you want to use React within a module system, <a href="http://github.com/facebook/react">fork our repo</a>, <code>npm install</code> and run <code>grunt</code>. A nice set of CommonJS modules will be generated. Our <code>jsx</code> build tool can be integrated into most packaging systems (not just CommonJS) quite easily.</p>
