Currently the routing in Express framework requires the module to be loaded before. But that would not be efficient in real life scenarios where there are hundreds of module. I would like to load only the module that is needed. Is there a way where I can define a route to a target module without pre loading the module. 

Something like this

app.get('user/showall', 'user.list');

So I would like user module to be loaded only when that particular request needs it to be loaded.
