&gt;which in my limited experience doesn&#x27;t do nearly a good a job of minifying Javascript than other tools (because it can&#x27;t do symbol renaming).<p>It&#x27;s possible to extract js-code from the vulcanized html file to the separate js-file using the crisper command, than run the uglifyjs command with appropriate minification arguments.<p>Example:<p><pre><code>   vulcanize --inline-css --inline-scripts .&#x2F;index.html | crisper -h .&#x2F;build&#x2F;index.html -j .&#x2F;build&#x2F;script.js
   cd .&#x2F;build
   uglifyjs -m -c warnings=false -o .&#x2F;script.js --source-map=.&#x2F;script.js.map .&#x2F;script.js</code></pre>
