Episode 24/13: Native Signals, Details on Angular/Wiz, Alan Agius on the Angular CLI
Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

A love letter to Apache Echarts
If you are generally interested in how to write components that can be used by many frontend libraries (react/vue, etc), you should take a look at https://github.com/microsoft/fast. I was tangentially involved with porting an existing component library to it and the end result was pretty framework agnostic and well made.

Microsoft's Adaptive UI

Making Web Component properties behave closer to the platform
I know FAST is not used that much but I wanted to cover it as it seems to be the only library that reflects attributes by default. By default it won't do any type coercion unless you use the mode: "boolean", which works almost like an HTML boolean attribute, except an attribute present but with the value "false" will coerce to a property value of false!

Shadow DOM: Not by Default
This doesn't mean you are required to write vanilla JavaScript web components either. If you are familiar with using Fast or Lit to write web components you can include those libraries in you Enhance application. However, with the introduction of Enhance base classes for the light and shadow DOM you can get the same DX improvements where you write less boilerplate web component code while enabling the sharing of a render method between the SSR and CSR rendering.
