google-closure-library | LONGER UPDATED - OFFICAL REPO MOVED

On a fresh lein new re-frame bc +handler app, if I lein uberjar or lein jar it doesnt seem to set the main class correctly. At the end of the compillation it tells me

Warning: The Main-Class specified does not exist within the jar. It may not be executable as expected. A gen-class directive may be missing in the namespace which contains the main method, or the namespace has not been AOT-compiled.

Here is the server.clj and project.clj that is created using the re-frame +handler template:

I am trying to reproduce HMAC signature described here.

The example is using crypt from nodejs, however, in my case, I need to use the google closure library. So I tried to reproduce the HMAC signature using the goog.crypt.Hmac library.

Below are my experiment code.

I am writing a web application with the backend in Clojure and the frontend in Clojurescript with React and Reagent. I am trying to host it on Heroku.

When I run lein ubjerar locally, it builds fine and the app works.

However, when I try to deploy the app to Heroku via git push heroku master, I always end up with an error like this:

Multiple Hmac encrypters ouput a different result of google closure library.

I've tried multiple Hmac encrypters and they output the same result. However, when using google closure library, both in NodeJS and ClojureScript, it outputs a totally different result.

I am trying to find an alternative for plovr while development, because plovr is a little bit far behind and upgrading google closure every time is becoming troublesome there.

So I considered using gulp. I set up a gulp webserver using gulp connect and on fallback, it triggers the google closure compile, then it waits until the file is generated and it will then serve it to the client. The problem that I am facing is that the compile time is much bigger than plovr ~40s vs ~20s. For a frontend developer that will be a long time to wait for the page to load after a small change. Any idea what can be done to optimize the compile time of the closure compiler. Here is my gulpfile.js to give you an idea about my setup.

I'd like to recreate a web version of FreeSurfer pial/white surfaces overlaid on T1.mgz similar to the first freeview image at https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/PialEdits_freeview. Using XTK I can get something that hints at that using advice from Othographic Projection in XTK. The code I used to create the image (along with kruft from multiple attempts) is below the image.

Is this possible with XTK or should I switch over to AMI.js (which has freesurfer surfaces and MGZ file formats on their roadmap but are not implemented)?

In either case, pointers to how to accomplish this would be appreciated.

Thanks.
