r.js minified optimized file not running - optimization

Question

BEFORE, I was using r.js to optimize and minify my javascript successfully. I had a main.js file that looked something like this:
require.config({
baseUrl: "scripts/lib",
paths: {
jquery: "http://code.jquery.com/jquery-1.11.2.min",
underscore: "https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min",
d3: "d3-for-development",
katex: "https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.3.0/katex.min", // or 0.2.0
mathjax: "http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML&delayStartupUntil=configured",
etc...
},
shim: {
underscore: { exports: "_" },
chosen: { deps: ["jquery"] },
mathjax: {
exports: "MathJax",
init: function (){
MathJax.Hub.Config({
tex2jax: {
inlineMath: [['$','$'], ['\\(','\\)']],
processEscapes: true,
},
});
MathJax.Hub.Startup.onload();
return MathJax;
}
},
},
});
require( [
"jquery",
"underscore",
"browser-detect",
"check-types",
"katex",
"mathjax",
etc
], function(
$,
_,
browser,
check,
katex,
mathjax,
etc
){
/////////////////////////// INITIALIZATION ///////////////////////////
loginInit()
show('#login')
etc...
and I could successfully run node build/r.js -o mainConfigFile=www/scripts/main.js baseUrl=www/scripts/lib name=../main out=www/scripts/main-optimized.min.js generateSourceMap=true preserveLicenseComments=false optimize=uglify2 to minify. Everything worked.
NOW, I have a config.js file that looks like this:
require.config({
urlArgs: "bust=" + new Date().getTime(),
baseUrl: "scripts/lib",
paths: {
jquery: ["jquery-min", "http://code.jquery.com/jquery-1.11.2.min"],
underscore: ["underscore-min", "https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min"],
d3: "d3-for-development", // if we add patches separately, then we can just use https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.5/d3.min
katex: ["katex-min", "https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.3.0/katex.min"], // or 0.2.0
mathjax: "http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML&delayStartupUntil=configured",
main: "../main",
etc...
},
shim: {
underscore: { exports: "_" },
chosen: { deps: ["jquery"] },
mathjax: {
exports: "MathJax",
init: function init() {
MathJax.Hub.Config({
tex2jax: {
inlineMath: [['$', '$'], ['\\(', '\\)']],
processEscapes: true }
});
MathJax.Hub.Startup.onload();
return MathJax;
}
}
}
});
require(["main"], function (main) {
// pass. by loading main, we run main.js
});
Instead of passing the minify/optimize arguments straight into the command line, I've created a rbuild.js file for that:
({
mainConfigFile: "../www/scripts/config.js",
baseUrl: "../www/scripts/lib",
name: "../config",
out: "../www/scripts/config-optimized.min.js",
generateSourceMap: true,
preserveLicenseComments: false, // this is necessary for generateSourceMap to work
optimize: "uglify2",
// removeCombined: true,
// findNestedDependencies: true,
paths: {
// https://github.com/jrburke/requirejs/issues/791
// http://www.anthb.com/2014/07/04/optimising-requirejs-with-cdn-fallback
jquery: "jquery-min",
underscore: "underscore-min",
d3: "d3-for-development",
katex: "katex-min",
mathjax: "http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML&delayStartupUntil=configured",
marked: "marked",
chosen: "chosen-min",
jsnetworkx: "jsnetworkx-min",
main: "../main",
},
})
and I run it with node build/r.js -o build/rbuild.js in the command line. It appears to run successfully and makes the config-optimized.min.js file, as expected. The output is:
Tracing dependencies for: ../config

But when I visit index.html via my server, the page is blank. The JS console gives no errors or log messages, which suggests that no JS is being run. My server gives no errors, which suggests that everything has been sent to the client successfully, and the client JS is not running.
So I'm pretty convinced the JS is there but not running. Is there something wrong with my setup that causes config.js to not run the code? With no error messages, I am having trouble troubleshooting :)

Answer 1

So I commented out
generateSourceMap: true,
preserveLicenseComments: false, // this is necessary for generateSourceMap to work
optimize: "uglify2",
and it worked! THEN, I uncommented that stuff, and it STILL worked!
It seems that as of requireJS 2.2 (I was using RequireJS 2.1.6 BEFORE), you can now use
optimize: "uglify",
or nothing at all, since this is the default setting. As of requireJS 2.2, it DOES use uglify2 in this case. This is the closest thing to an explanation that I can give :/
