Koa.js features and specs

Lightweight
Koa.js is designed to be a smaller, more expressive, and more robust foundation for web applications and APIs, minimizing the middleware interface.
Modern JavaScript
Koa.js is built using modern JavaScript features, such as async/await, making the code more readable and easier to maintain.
Modularity
Koa provides a suite of methods that make writing servers fast and enjoyable. Additionally, it doesn't come with middleware, so you can pick and choose the pieces you need, resulting in a more tailored application.
Error Handling
Koa has improved error handling mechanisms compared to some other Node.js frameworks, streamlining the process of catching and managing errors.
Performance
Due to its lightweight nature and the absence of bundled middleware, Koa generally has better performance metrics in terms of speed and memory consumption.

Possible disadvantages of Koa.js

Steeper Learning Curve
Koa's minimalist approach and reliance on new JavaScript syntax can be challenging for beginners or those who are more accustomed to frameworks like Express.js.
Lack of Middleware
Although its lack of built-in middleware promotes modularity and flexibility, it also means that developers have to spend additional time incorporating necessary middleware components.
Smaller Ecosystem
Koa has a smaller ecosystem compared to more mature Node.js frameworks like Express.js. This could result in less community support and fewer third-party plugins and extensions.
Less Documentation
While Koa.js has its official documentation, there are fewer tutorials, guides, and comprehensive resources available compared to some other more established frameworks.
Compatibility Issues
Given that Koa.js leverages modern JavaScript features, it may not be compatible with all Node.js versions or legacy systems, necessitating careful consideration during adoption.

Rectangle features and specs

Ease of Use
Rectangle offers an intuitive user interface that makes window management straightforward and user-friendly.
Customizable Shortcuts
Users can easily configure keyboard shortcuts to better suit their workflow, making window management faster and more efficient.
Free
Rectangle is available for free, making it accessible to anyone without the need for a financial investment.
Frequent Updates
The app receives regular updates, introducing new features and ensuring compatibility with the latest macOS versions.
Lightweight
Rectangle is a lightweight application that doesn't consume many system resources, ensuring smooth performance even on older Macs.

Possible disadvantages of Rectangle

Limited Advanced Features
Rectangle lacks some of the more advanced features found in paid window management applications, such as multiple monitor support and more complex window arrangements.
MacOS Only
Rectangle is only available for macOS, so users of other operating systems are unable to take advantage of its features.
Occasional Bugs
Some users report occasional bugs or unpredictable behavior, which might require troubleshooting or waiting for a future update.
Learning Curve for Shortcuts
While customizable shortcuts are a benefit, there is an initial learning curve for users to memorize and effectively use these shortcuts.
Basic Aesthetic
The app's design and aesthetic are quite basic, lacking the polish and visual appeal found in some other similar tools.

About Taxum, or why I wrote my own NodeJS Framework
I very quickly switched from raw JavaScript to TypeScript due to the improved DX experience and type safety. With that switch I also looked for a framework back then which not only supported TypeScript better, but also had proper support for async-await. This made me land on Koa at the time. - Source: dev.to / 9 months ago

Make macOS consistently bad (unironically)
Rectangle [1] is pretty much essential for me because of this. I use only a few keypresses (maximize window, move to one of the halves of the screen horizontally) but that is enough. My mouse very rately interacts with the borders of any window, or those buttons. I had to click on the green one that you mentioned in order to see what it did (yuck).

Make macOS consistently bad (unironically)
I use Rectangle [1] for window management. I only use three shortcuts: full screen, left half of the screen, and right half of the screen. My editors and chrome are always running in one of these modes. But for other apps like Messages, Notes, Music, etc - yeah I don't usually expand them to full screen.
