In this post, I will be introducing three strategies that can help Node developers who wish to loosen their code. First, we’ll cover microservices with Moleculer. Then, we’ll through Inversion of Control with InversifyJS. Finally, we’ll discuss N-Tier Architecture and why it’s helpful.
If you’ve been writing code for a significant amount of time, you’re sure to have seen the—anything but godly—“God Method.” It’s a method that performs way too many processes in the system and has grown beyond all realistic logic to become “The Method That Does Everything.”
This single unsightly method can span dozens, if not hundreds, of lines. Sometimes even over 1,000! This type of “ugly code” is an unbearable beast to maintain. This is why it’s considered a “code smell” or anti-pattern.
In this tutorial, we walk through a tangible “God Method” and step through the process to refactor it into something more manageable and human-readable. Our code is written in JavaScript for a Node.js service, but the principles apply to any language.
Earlier this year I blogged about creating a Lean Mean Vue Machine called Quotes on Demand. The application was a fully featured CRUD application served from a NodeJS server and had a self contained VueJS front end.
But wouldn’t it be a nice test to see if that same Vue application could switch over to another API, say something like a Python web server powered by Flask?
In this post, we will create a Python web application that will have 100% parity to an existing NodeJS web application. This will enable an existing VueJS front end to connect to the application with no additional code changes in the user interface code.
