Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A Proposal to Add Signals to JavaScript: A Mistake?
Recently, there's been a buzz about a proposal to introduce Signals to JavaScript. But before diving in, what exactly is a signal?

What We Need Instead of "Web Components"
> especially since Observables have been widely available and actively worked on for a long time, without seeing wide adoption
Take a look at "Userland libraries" section [0] of the proposal (almost certainly written by Ben). He argues that observables get reinvented in the userland in various libraries over and over again. It is a primitive, like a Promise, only better.

You Don't Need to “Learn” Svelte: Embracing the Simplicity of JavaScript
Perhaps this falls into the repetitive boilerplate category you referred to, but if you want framework-agnostic domain objects that still work well with Svelte, create your own using the observer pattern.
Create an object with a subscribe method and whatever other methods make sense for updating its state. Svelte will treat it like one of its stores, and it will work with the $ syntax. It can be used with React via its `useSyncExternalStore` hook. It can be used with SolidJS via its `from` utility.
If you don't want to handle the set-up boilerplate, you could use another library like Effector or RxJS, but of course, that means another dependency. There is a gradual move to make something like this a part of the platform[1], but who knows when or if it will land.
