React Without JSX
|
|
</h1>
|
|
<div class="subHeader"></div>
|
|
|
|
<p>JSX is not a requirement for using React. Using React without JSX is especially convenient when you don't want to set up compilation in your build environment.</p>
|
|
|
|
<p>Each JSX element is just syntactic sugar for calling <code>React.createElement(component, props, ...children)</code>. So, anything you can do with JSX can also be done with just plain JavaScript.</p>
|
|
|
|
<p>For example, this code written with JSX:</p>
|
|
<div class="highlight"><pre><code class="language-js" data-lang="js"><span class="kr">class</span> <span class="nx">Hello</span> <span class="kr">extends</span> <span class="nx">React</span><span class="p">.</span><span class="nx">Component</span> <span class="p">{</span>
|
|
<span class="nx">render</span><span class="p">()</span> <span class="p">{</span>
|
|
<span class="k">return</span> <span class="o"><</span><span class="nx">div</span><span class="o">></span><span class="nx">Hello</span> <span class="p">{</span><span class="k">this</span><span class="p">.</span><span class="nx">props</span><span class="p">.</span><span class="nx">toWhat</span><span class="p">}</span><span class="o"><</span><span class="err">/div>;</span>
|
|
<span class="p">}</span>
|
|
<span class="p">}</span>
|
|
|
|
<span class="nx">ReactDOM</span><span class="p">.</span><span class="nx">render</span><span class="p">(</span>
|
|
<span class="o"><</span><span class="nx">Hello</span> <span class="nx">toWhat</span><span class="o">=</span><span class="s2">"World"</span> <span class="o">/></span><span class="p">,</span>
|
|
<span class="nb">document</span><span class="p">.</span><span class="nx">getElementById</span><span class="p">(</span><span class="s1">'root'</span><span class="p">)</span>
|
|
<span class="p">);</span>
|
|
</code></pre></div>
|
|
<p>can be compiled to this code that does not use JSX:</p>
|
|
<div class="highlight"><pre><code class="language-js" data-lang="js"><span class="kr">class</span> <span class="nx">Hello</span> <span class="kr">extends</span> <span class="nx">React</span><span class="p">.</span><span class="nx">Component</span> <span class="p">{</span>
|
|
<span class="nx">render</span><span class="p">()</span> <span class="p">{</span>
|
|
<span class="k">return</span> <span class="nx">React</span><span class="p">.</span><span class="nx">createElement</span><span class="p">(</span><span class="s1">'div'</span><span class="p">,</span> <span class="kc">null</span><span class="p">,</span> <span class="err">`</span><span class="nx">Hello</span> <span class="nx">$</span><span class="p">{</span><span class="k">this</span><span class="p">.</span><span class="nx">props</span><span class="p">.</span><span class="nx">toWhat</span><span class="p">}</span><span class="err">`</span><span class="p">);</span>
|
|
<span class="p">}</span>
|
|
<span class="p">}</span>
|
|
|
|
<span class="nx">ReactDOM</span><span class="p">.</span><span class="nx">render</span><span class="p">(</span>
|
|
<span class="nx">React</span><span class="p">.</span><span class="nx">createElement</span><span class="p">(</span><span class="nx">Hello</span><span class="p">,</span> <span class="p">{</span><span class="nx">toWhat</span><span class="o">:</span> <span class="s1">'World'</span><span class="p">},</span> <span class="kc">null</span><span class="p">),</span>
|
|
<span class="nb">document</span><span class="p">.</span><span class="nx">getElementById</span><span class="p">(</span><span class="s1">'root'</span><span class="p">)</span>
|
|
<span class="p">);</span>
|
|
</code></pre></div>
|
|
<p>If you're curious to see more examples of how JSX is converted to JavaScript, you can try out <a href="https://babeljs.io/repl/#?babili=false&evaluate=true&lineWrap=false&presets=es2015%2Creact%2Cstage-0&code=function%20hello()%20%7B%0A%20%20return%20%3Cdiv%3EHello%20world!%3C%2Fdiv%3E%3B%0A%7D">the online Babel compiler</a>.</p>
|
|
|
|
<p>The component can either be provided as a string, or as a subclass of <code>React.Component</code>, or a plain function for stateless components.</p>
|
|
|
|
<p>If you get tired of typing <code>React.createElement</code> so much, one common pattern is to assign a shorthand:</p>
|
|
<div class="highlight"><pre><code class="language-js" data-lang="js"><span class="kr">const</span> <span class="nx">e</span> <span class="o">=</span> <span class="nx">React</span><span class="p">.</span><span class="nx">createElement</span><span class="p">;</span>
|
|
|
|
<span class="nx">ReactDOM</span><span class="p">.</span><span class="nx">render</span><span class="p">(</span>
|
|
<span class="nx">e</span><span class="p">(</span><span class="s1">'div'</span><span class="p">,</span> <span class="kc">null</span><span class="p">,</span> <span class="s1">'Hello World'</span><span class="p">),</span>
|
|
<span class="nb">document</span><span class="p">.</span><span class="nx">getElementById</span><span class="p">(</span><span class="s1">'root'</span><span class="p">)</span>
|
|
<span class="p">);</span>
|
|
</code></pre></div>
|
|
<p>If you use this shorthand form for <code>React.createElement</code>, it can be almost as convenient to use React without JSX.</p>
|
|
|
|
<p>Alternatively, you can refer to community projects such as <a href="https://github.com/mlmorg/react-hyperscript"><code>react-hyperscript</code></a> and <a href="https://github.com/ohanhi/hyperscript-helpers"><code>hyperscript-helpers</code></a> which offer a terser syntax.</p>
