The demo aims to teach the basics of the Angular compiler.

The angular template compiler transforms angular templates (HTML) into javanoscript.
The templates are compiled into view functions made of sequential calls of instructions.
Angular instructions are functions that are easily recognizable with their leading ɵɵ.

Angular's signals have been quite a revolution since they came out, from new state management approach to a brand new way of rethinking reactivity within applications, signals have deeply influenced the framework's ecosystem.

While most of its primitives are stable, effect is still in developer preview as of the time I'm writing this article, and can often lead to errors or warnings.

In this post, we will cover the basics of the usage of effect, some tips and tricks I use, and showcase a way to enhance their behavior.

Enhance the way your CLIs report progress to users. While there are many developer experience improvements we could make to most command-line apps, I see this one as absolutely essential. If you are creating an app or a shell noscript for a terminal emulator and you’re pressed for time but can only squeeze in one more improvement, make sure it is how your app displays progress for long-running processes.
