I think you might want to look at a Facade pattern. The idea being you
create a NEWAPP namespace with a whole new API - this acts as a facade on to
the original, monolithic, code.
*original file:*
APP = {
foo : function() {},
bar: function() {},
baz: function() {}
}
(NB - it's irrelevant whether the above is in a closure or not, asuming that
it provides APP.foo to the global namespace)
*new file:*
var NEWAPP = {};
(function(na) {
// passed the "namespace" in as a
// parameter, so it's super easy to
// change any time you like, without
// touching any code inside this
// closure
// you can have "private" functions
var privateFunction = function() {};
// and add the new "public" api
na.publicFunction = function() {
var fooOK = APP.foo(),
barOK = APP.bar();
return (fooOK && barOK);
};
})(NEWAPP);
*implementation file / web page:*
NEWAPP.publicFunction();
In this example, you would create "wrapper" methods in the NEWAPP namespace
that internally call methods inside APP, but in some nicer fashion.
Best,
Pete
