Obfuscate RequireJS module name [duplicate] - node.js

Question

This question already has an answer here:
Replace module ids with fake names
(1 answer)
Closed 7 years ago.
My project layout is:
-bin\
-out.closeure.js // (compiled from out.js using the closure compiler)
-out.js // this is the requirejs output file, no minification done)
-src\
-lib\
-library.js
-main.js
-somefile.js
Now when I use RequireJS to combine my project to a single file, is there a way to mangle the names of the module? For example in main.js instead of:
require(['somefile'], function(SomeFile){
//blah
});
I'll have
require(['a6fa7'], function(SomeFile){
//blah
});
Since I am using closure compiler to obfuscated everything, the only thing not being mangled is the module names, and I want to mangle that as well.
I looked at the https://github.com/stevensacks/grunt-requirejs-obfuscate plugin but it's not working and I'm not sure if that plugin does what I want.

Edit1: I encourage to use instead AMDclean, there may be no reason to keep the footprint amd produce on an optimized build. If you want to keep it, the following way is the workaround i made:
Use the onBuildWrite and onBuildRead as the documentation states:
onBuildWrite A function that will be called for every write to an optimized bundle of modules. This allows transforms of the content before serialization.
"replaceModuleNames": [],
//executed on every file read
onBuildRead: function(moduleName, path, contents){
this["replaceModuleNames"].push({
"name": moduleName,
"with": makeid()
});
//Always return a value.
return contents;
},
onBuildWrite: function (moduleName, path, contents) {
console.log("moduleName: " + moduleName + " ,path: " + path + " ,contents: ... ");
var text = contents;
RegExp.escape = function(text) {
return text.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, "\\$&");
};
this["replaceModuleNames"].forEach(function(element){
var regE = new RegExp('(?:define\\(|require\\().*(?:"|\')('+RegExp.escape(element["name"])+')(?:"|\')');
text = text.replace(regE, function(a, b){
return a.replace(b, element["with"]);
});
console.log("moduleName: "+moduleName+ " replaceWith: " + element["with"] + " result: " + text);
});
//Always return a value.
return text;
}
Place it on the build.js, you have to implement makeid method,
i tested it but it might fail, so dont rely on it for production
Edit2: text.replace(element["name"], element["with"]); may cause inconsistent code, replaced with regexp groups, i am not experienced with regex so its open to improvements.
