​​The MERN stack consists of MongoDB, Express, React / Redux, and Node.js. Given the popularity of React on the frontend and of Node.js on the backend, the MERN stack is one of the most popular stack of technologies for building a modern single-page application.

​​Validation of data is an interesting topic, we tend to write code that looks really horrible in the sense that it contains a lot of checks. There are different situations when we need to perform these checks like validating a response from a backend endpoint or maybe verifying what goes into our REST API won’t break our code. We will focus on the latter, how to validate our API.

When developing an npm package, you have confirm that it can actually be used. It’s great if tests pass, examples build, and demos run, but it’s broken if consumers can’t install it. npm provides a tool to help test packages before publishing, npm link.

​​This is the typical structure I use for my medium-sized Node backends. For small backends, I'd probably just put everything in one file and I might not bother with build tooling.

​​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.
