Node module system is locked and is never going to change anyway. Think about it as a static linking system and nothing more. Even with hacks like you suggested it is still insufficient for dynamic linking.
The advice is: 1) Do not rely on require system if you want runtime configuration, design modules in advance in such way that they could be configured if needed. 2) For app level components use custom container. (That seems to be the most common use case where you actually need such configuration) 3) If there is a third party module involved consider to just monkey patch it's dependency. In addition you might find the following modules useful easy-app<https://github.com/eldargab/easy-app> , fake-fs <https://github.com/eldargab/node-fake-fs> On Sunday, January 20, 2013 8:15:13 AM UTC+4, Athan Clark wrote: > > Hello everyone.
