<h1 class="title">Optimize</h1>
<p>JavaScript code generated by the pyjs compiler <tt class="docutils literal">pyjsbuild</tt> is relatively large, unobfuscated and uncompressed.</p>
<div class="section" id="reduce-size">
<h1>Reduce Size</h1>
<p>Take a look at the <tt class="docutils literal">pyjscompressor.py</tt> script in the <a class="reference external" href="https://github.com/pyjs/pyjs/blob/master/contrib">contrib folder</a>, which will do a great job in dramatically reducing the size of the generated JavaScript code.</p>
</div>
<div class="section" id="increase-speed">
<h1>Increase Speed</h1>
<p><tt class="docutils literal">pyjsbuild</tt> command line switch <tt class="docutils literal"><span class="pre">-O</span></tt>, <tt class="docutils literal"><span class="pre">--enable-speed</span></tt> optimizes JavaScript output for speed.</p>
<p>Improving responsiveness may be able using the <tt class="docutils literal"><span class="pre">--enable-strict</span> <span class="pre">--disable-debug</span> <span class="pre">--dynamic-link</span></tt> command line switches. This generates more files instead of copying modules into <tt class="docutils literal">*cache.html</tt> files.</p>
</div>
<div class="section" id="obfuscate">
<h1>Obfuscate</h1>
<p>Although there is no specific obfuscator provided for pyjs you can use any tool available for JavaScript code (e.g. see this <a class="reference external" href="http://stackoverflow.com/questions/194397/how-can-i-obfuscate-javascript">StackOverflow question</a>).</p>
