<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 code can live in a separate file. Create the following <code>src/helloworld.js</code>.</p>
|
|
<div class="highlight"><pre><code class="language-javascript" data-lang="javascript"><span class="nx">React</span><span class="p">.</span><span class="nx">render</span><span class="p">(</span>

<span class="o"><</span><span class="nx">h1</span><span class="o">></span><span class="nx">Hello</span><span class="p">,</span> <span class="nx">world</span><span class="o">!<</span><span class="err">/h1>,</span>

|
|
<span class="p">);</span>
|
|
</code></pre></div>
|
|
<p>Then reference it from <code>helloworld.html</code>:</p>
|
|
<div class="highlight"><pre><code class="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="language-text" data-lang="text">npm install -g react-tools
|
|
</code></pre></div>
|
|
<p>Then, translate your <code>src/helloworld.js</code> file to plain JavaScript:</p>
|
|
<div class="highlight"><pre><code class="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>
|
|
<div class="highlight"><pre><code class="language-javascript" data-lang="javascript"><span class="nx">React</span><span class="p">.</span><span class="nx">render</span><span class="p">(</span>

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

<p>If you want to use React with <a href="http://browserify.org/">browserify</a>, <a href="http://webpack.github.io/">webpack</a>, or another CommonJS-compatible module system, just use the <a href="https://www.npmjs.org/package/react"><code>react</code> npm package</a>. In addition, the <code>jsx</code> build tool can be integrated into most packaging systems (not just CommonJS) quite easily.</p>
