Hi, minification can always be a problem, we ran into issues in other frameworks / languages, too...
Instead of disabling Minification for all files, or for a single browser, you could also just replace the Google Closure compiler with a more selective one: https://gist.github.com/benweidig/db9d427c01c573b94cc5a492f88f7c39 public class CustomGoogleClosureMinimizer extends GoogleClosureMinimizer { public CustomGoogleClosureMinimizer(Logger logger, OperationTracker tracker, AssetChecksumGenerator checksumGenerator, Request request, @Symbol(WebResourcesSymbols.COMPILATION_LEVEL) CompilationLevel compilationLevel) { super(logger, tracker, checksumGenerator, request, compilationLevel); } @Override protected boolean isEnabled(StreamableResource resource) { if (resource.getDescription().endsWith("underscore-1.8.3.js")) { return false; } return super.isEnabled(resource); } } and overriding the original with @Contribute(ResourceMinimizer.class) @Primary public static void overrideGoogleClosureCompiler(MappedConfiguration<String, ResourceMinimizer> conf, @Autobuild CustomGoogleClosureMinimizer gcm) { conf.override("text/javascript", gcm); } This way only the offending file won't be minimized, everything else will be handled as usual. I've debugged through a project of mine, it looked good for me. To implement browser-related compression of a single file you would have to go even earlier in the request (e.g. StreamableResourceSource).
