The backend was implemented using RackStep, a Ruby library I was developing at the time, in conjunction with MongoDB. To keep things simple, I chose Heroku as the cloud provider. For the frontend, I decided to implement everything in pure JavaScript! I would never do this in an application at work but, as it was something quite experimental, I chose to do everything without any library or framework and figure out in practice - through a lot of pain, trial and error - the kind of problems those fancy JavaScript libraries and frameworks could help me with in future projects. The question I wanted to answer was essentially this: what is the minimum amount of dependencies required to develop a SPA? At first I thought it would be zero. And so it was, until production. Even the build scripts were made using only the good old bash script. To be honest, I used some dependencies to minify (reduce the size) of the files. I also used the Google Maps API. That's all.

Although Virtual DOM is a fairly appropriate way to solve the problems described throughout this article, not every modern library and framework uses this concept. Svelt, for example, uses another approach. So it is clear that there are alternative ways to handle these problems, each with its advantages and disadvantages.

It took me a while to get into the single-page applications wave. When the first versions of Angular, React, Elm and so many other solutions for creating SPAs appeared, at work I was still implementing systems using the old-fashioned JSF (JavaServer Faces) and, at home, was trying out Ruby on Rails and also learning how to develop native Apps for iOS and Android.

After learning The Elm Architecture (or MVU Architecture), it became much easier to understand Android's Jetpack Compose, Apple's SwiftUI, the mechanism for creating and updating the screens in Flutter and also, of course, React Native.

I vividly remember a conversation I had with a co-worker in 2013. He was enthusiastic about a JavaScript library developed internally by Facebook that the company had decided to make open-source. I'm talking, of course, about React.

Around 2017 I began to be interested in functional programming. I went straight into the most extreme language I found at the time: Haskell. After reading a lot and taking some online courses, I could barely get away with the famous "hello world". 😬 It was tough. The potential advantages of that approach were noticible, but in practice I could do almost nothing. Frustrated, looked for simpler alternatives. Didn't want to give up, but I decided to postpone this adventure into Haskell. I had clearly bitten off more than could chew, especially since there was no one around with the necessary knowledge to guide me properly. That's when I decided to learn the Elm programming language. 🌳
