The problem arises when we need to actually construct the pieces that make up these SOA components. We are stuck implementing the same boilerplate code over and over again and stringing together various modules with no standard interface. When you require(‘my-cool-module') you have no idea what you will get back. This is the major issue with module based development today...
What's needed is what I would call the containerization of functions. We need to focus on making it easier to get new developers on board and make it easier to maintain complex code bases so that we can focus on what's important: shipping code. We are working on a project for this now in the node community called Node-Machine which we hope will be a step forward in solving some of these issues.
