Functional Programming Unit Testing in Node – Part 1

Functional Programming Unit Testing in Node

Writing Functional Programming in Node is one challenge, but unit testing it is another. Mainly because many middlewares in Node use the connect middleware approach, and libraries in Node are not written in a pure function way.

This six part series will go over how to make the unit testing part of easier, some strategies to tackle common impurity problems, and hopefully enable to make 100% test coverage a common part of your job vs. the “not worth the client investment” people commonly associate with it.

Node.js Crash Course

Introduction

I’ve been doing Node full-time at work and noticed a lot of other people lacking a centralized resource to get up and running quickly. There are a lot of wonderful resources out there for Node, a Google search away, but hopefully this document should get you coding quickly as well as able to communicate effectively with other Node developers.

I’ve tried to write this list in order of most important things you need to know. Feel free to skip around.

Error Handling Strategies

Introduction

There are various ways of handling errors in programming. This includes not handling it. Many languages have created more modern ways of error handling. An error is when the program, intentionally, but mostly not, breaks. Below, I’ll cover the 4 main ones I know: try/catch, explicit returns, either, and supervising crashes. We’ll compare various languages on how they approach errors: Python, JavaScript, Lua, Go, Scala, Akka, and Elixir. Once you understand how the newer ways work, hopefully this will encourage you to abandon using potentially program crashing errors via the dated throw/raise in your programs.
