Managing Software Unpredictability improves your tests — You know how when you sweep a room, you’re gathering dust into one corner of the room, so you can manage it easily? Like there’s nothing stopping you from iteratively moving dust into the dustpan for each square foot of the room, if you’re so inclined? It’s just a lot…

I found TypeScript challenges on GitHub when I wanted to improve my TypeScript skills. Before then, I knew basic typescript such as const name: string = "John Doe"; const age: number = 100; type Person = { name: string; age: number } const person: Person = { name, age } const getPersonName =…

A dumping ground for code that does not fit anywhere — You’re writing code, following an architecture that works for you. Everything fits into place until you write a function, and you keep it in a utils folder because it’s not clear where such a function should live. Perhaps such a function is used in multiple places and that is enough…

Handling styles that only show up at runtime — Like many, I use PurgeCSS to remove unused CSS in my frontend apps. It does the job by scanning through source files such as HTML, Pug, JSX and even CSS, to find styles the application uses, then it filters a target CSS file to only have styles that are used. …

I like Storybook because it provides visual documentation for my components, and let’s me build them in isolation, encouraging good coding principles like SOLID. But I always wondered how I could get more out of it, and justify the time spent building stories for components. The first time I added…

Based on conversation with @thatdeji on Twitter — I received an interesting question about “Refactoring: TF is Dependency Inversion”, which sparked a conversation that I thought to share that as an article with some paraphrasing to focus on relevant context. TL;DR; The conversation was about how to tell where DI is necessary, and we touched on topics like Side…

If you’re touchy about language, TF stands for “The Flip” 😋, and when you read this, you’ll see why. — In a codebase, everything exists in hierarchies, whether it’s file-system or logical hierarchies. Everything depends on something else, or is depended on, else it becomes dead code. These hierarchies tend to create strong structures that can be resistant to change. Imagine having to replace the above block. The sheer number…

How do I pick the right abstractions? Are there rules that can be followed? — Let’s look at an example, and see if we can apply some rules to make code cleaner. Example Assume you are a dev working on a Web3 project where users can send tokens as gifts to one another. Given a function: This is a huge function that does many things…
