What are design patterns?

A design pattern is a general, reusable solution to a commonly occurring problem.

Singletons- The singleton patterns restrict the number of instantiations of a "class" to one. Creating singletons in Node.js is pretty straightforward, as require is there to help you.

Middleware’s / pipelines- Middleware’s are a powerful yet simple concept: the output of one unit/function is the input for the next. If you ever used Express you already used this concept.

The Swagger Descriptor- This methodology is called design-driven development. Firstly we design our endpoints' behavior by describing them in either a YML or a JSON file. This is the most important task and everyone in the team should take part of it.

Our Team focus on JS Designing and we built and use it.

As an asynchronous event driven framework, Node.js is designed to build scalable network applications. In the following "hello world" example, many connections can be handled concurrently. Upon each connection the callback is fired, but if there is no work to be done Node is sleeping.

Node is similar in design to and influenced by systems like Ruby's Event Machine or Python's Twisted. Node takes the event model a bit further, it presents the event loop as a language construct instead of as a library. In other systems there is always a blocking call to start the event-loop.

Typically one defines behaviours through call-backs at the beginning of a script and at the end starts a server through a blocking call. In Node there is no such start-the-event-loop call. Node simply enters the event loop after executing the input script. Node exits the event loop when there are no more call-backs to perform. This behaviour is like browser JavaScript -— the event loop is hidden from the user.

HTTP is a first class citizen in Node, designed with streaming and low latency in mind. This makes Node well suited for the foundation of a web library or framework.

Just because Node is designed without threads, doesn't mean you cannot take advantage of multiple cores in your environment. You can spawn child processes that are easy to communicate API. Built upon that same interface is the cluster module, which allows you to share sockets between processes to enable load balancing over your cores.

Finally, Node.js is well instrumented for production usage. What that means is that there are the tools to help bring an application to full production readiness and performance. As with any maturing technology, there are areas where more documentation, tools, and best practices could be helpful. But as Node.js heads towards its next major release, it's on fairly solid footing.




Node in context

If you know JavaScript, Node.js is a gentle on-ramp to asynchronous computing for the Web. And it just so happens that Node.js is suited to solve Web problems exactly of this type: integration and glue challenges, with cascading calls to API after API.
