Utils Background

Utils Background is a library of utilities for common tasks. It was one of the first libraries I wrote, so it went through a lot of changes over the years (including 4 renames) and it is still changing.


The first version of this library was written for a gig I had at that time, and it was a collection of manually minified functions. I was trying to achieve the minimum amount of code possible for some common tasks. You can see how old this is by considering one of the utils was xhr and made use of XMLHttpRequest.

Over the years this evolved into a more modern library, making the code more readable and leaving minification to the consumer with bundlers, moving some utils away to their own packages, and adding new ones as I needed them.


I built this library using TypeScript (originally vanilla JavaScript), with configurations from my shared configs. I made it ESM only as soon as Node started supporting ESM modules, and I made it tree-shakeable by using named exports.


Currently I use this library from other libraries such as iterables, notify and the Paired Hook pattern ones, but also at work in private projects.
