I did some reading on enabling source maps for other languages (more material exists for e.g. coffeescript) and I think the problem is that lein cljsbuild is not adding that special comment to index.html to tell the browser about the source map
//# sourceMappingURL=/path/to/file.js.map in this case "dev/main/core.js.map" <!-- scripts and styles --> <script src="http://fb.me/react-0.12.1.min.js";></script> <script src="dev/goog/base.js" type="text/javascript"></script> <script src="dev/app.js" type="text/javascript"></script> <script type="text/javascript">goog.require("main.core");</script> But shouldn't goog.require be smart enough to add that? I have no idea since I've never used goog.* or the Closure compiler It's it lein's job to put that special comment line or is it Google's Closure's job? Or how does the line get added? We're definitely not sending an X header for source maps, so we must have that special comment (according to what I read) What am I missing here?
