Creating applications with Node can be a challenge especially when you come from other languages such as PHP, C# or Java. The underlying JavaScript is fundamentally different since it implements only a weak type system, has a different concept of packaging and the class system is not what it seems to be. So how to approach a new application? In this talk you will get to know several architecture and design patterns used widely in the node ecosystem such as data streams, the handling of asynchronous operations and parallel processing. You will see how they affect the way you work with Node and how they make your life easier.
