My Favorite Microservice Design Patterns for Node.js

After working for a while with Node.js I’ve come to the conclusion that there is no better tool to use when writing microservices. My Favorite Microservice Design Patterns for Node.js - I bet you can’t say Node.js isn’t a great tool for building microservices. And while Node.js by itself is a great tool, it’s going to come down to however you end up using it.

Saying you’re using REST is not good enough anymore

After working for a while with Node.js I’ve come to the conclusion that there is no better tool to use when writing microservices. Of course, that is my opinion, completely biased by my preference for JavaScript as a language. But hey, even without me pushing my own opinion into your eyes, I bet you can’t say Node.js isn’t a great tool for building microservices.

It provides very fast development times, lots of pre-existing frameworks and the async I/O allows for fantastic performance when dealing with a multitude of simultaneous requests.

And while Node.js by itself is a great tool, it’s going to come down to however you end up using it. With that in mind, here are some useful and interesting design patterns for your microservices. The idea is that you stop creating a single service for all your projects, there are many ways of splitting them up depending on the type of benefit you’re after. So let’s take a quick look at them.

Microservices Deserve Modern Programming Platforms: Java May Not be the Best Option

Decoding Nodejs

The main goal of this blog is to explain the “Architecture of Nodejs” and to know how the Nodejs works behind the scenes. Generally, most of the server-side languages, like PHP, ASP.NET, Ruby, and including Nodejs follows multi-threaded architecture.
