DescriptionResource minification/aggregation js
* We should aggregate and minimize the js sources in order to improve the load speed of the application;
* We dont want to use the yui combo loader feature;
* The final product will provide three js files: one for the YUI dependencies, one for our custom js code and one for third part js like d3.

Thanks for the branch.

Hi Thiago. Thank you for this nice step forward: it will be great when we have this functionality, and the debug/developer story you've arranged is nicer than I expected. This is a preliminary review. As I mention, I want to review merge-files.js more later, but I'm going to let Benji take a first pass and send my notes so far to you sooner. Gary https://codereview.appspot.com/6821090/diff/7001/Makefile File Makefile (right): https://codereview.appspot.com/6821090/diff/7001/Makefile#newcode64 Makefile:64: combinejs: $(NODE_TARGETS) As I mentioned on IRC, this has the same problem we talked about with sprite generation: every time you run the target it will try to compress the files. Since install depends on this, and just about everything depends on install, this can affect most make targets and be pretty annoying. One approach to solving this is http://pastebin.ubuntu.com/1340722/ https://codereview.appspot.com/6821090/diff/7001/Makefile#newcode89 Makefile:89: @rm -Rf app/assets/javascripts/generated/ Good. https://codereview.appspot.com/6821090/diff/7001/Makefile#newcode107 Makefile:107: combinejs Good. https://codereview.appspot.com/6821090/diff/7001/app/assets/combine/merge-fil...

This is a build component, and we never want to serve it as part of the application. I suggest that we put it in the top directory, or in bin. I lean towards bin.

Oh, no, I see. Cool, nicely done. Something to consider is what a static version of the GUI would look like, without server.js--and then how close we can get to that. The closer we can have our dev environment like our distributed environment, the better. Rather than having the server decide which .js file to serve, what about having two different index.html files, one of which serves the debug and one of which serves the normal version?

This is not part of the global solution.

One approach: > > require('yui').YUI().use(...); > > another approach: > > var Y = require('yui').YUI(), I did it because I dont require any internal yui code. I use it to get the Y.Object, Y.Array and Y.Loader objects. I cannot remove the line 4. It is used by the line 82. When node executes the line 82, it loads one of our js files. These js files call "YUI.add(..." and YUI is defined by "global.YUI". https://codereview.appspot.com/6821090/diff/7001/app/assets/combine/propertie...

I have added a review of app/assets/combine/merge-files.js (which should probably be in a different place, "assets" are things we use in the browser.

Correct, it has fewer than 80 characters but one of those characters is a tab, which in most editors displays as 8 spaces, pushing the line over 80 displayed characters. https://codereview.appspot.com/6821090/diff/7001/app/assets/combine/merge-fil...

This is looking good, Thiago. Thank you! As we discussed, I'm OK with holding off on tests. The last non-trivial thing I'd like to see is removing the code that writes properties. I give two possible approaches below. I'm happy to have a call if it helps, or leave it to you, as you prefer. Thanks!

My preferred approach, which we talked about yesterday, would be to make the server always have both the debug version (debug.html?) and the production version (index.html) available, by having the server dynamically change the js files that index.html points to. Alternatively, server.js would accept an argument to turn on debug mode.

Hi Thiago. This looks good to me. Per our discussions: - We are foregoing tests on the lib functions. You can see now how you would do them. You might do a follow-up branch with tests or might not. I would be happy to see that change. However, I won't stop you from landing this without them. - We are foregoing the "bootstrap=false" change that forces us to keep from downloading files. It would be a nice seatbelt but it had problems that you documented. Thank you!

This is in landable shape now. Thanks for the work on it, especially in review. Re. testing: My stance is that we can survive with the code being untested for the time being, but if/when we touch the code again solid tests need to be written first. I know if I'm the one doing the touching I'll certainly want the confidence that I am not breaking anything by changing the code.
