preact-custom-element VS eureka

I avoid using them, except when having to expose a component to a third party. Then I'd use something like https://github.com/preactjs/preact-custom-element, https://stenciljs.com/docs/custom-elements or https://github.com/solidjs/solid/tree/main/packages/solid-el....

As far as I see, there is nothing that WCs provide which isn't already solved, in a better way, both for devs and users.

And making a framework that use custom elements and shadow DOM for component-based logic and encapsulation seems like a purely philosophical approach to adhere to some vision of "platform purity".

Preact

Here's an example of building a well-structured, maintainable web-site using JavaScript, HTML and CSS: https://github.com/wisercoder/eureka/tree/master/webapp/Clie...

It doesn't use React (imagine the horror!), instead it uses two tine 500-line libs.

Not really. See a better way here: https://github.com/wisercoder/eureka

I'm not quite seeing React being used, just JSX though? All the view and state updating is being done manually, but it looks fairly well-organised. There are small optimisations like debouncing onInput with a timeout (avoiding rapid re-rendering for every character typed): https://github.com/wisercoder/eureka/blob/master/webapp/Clie...

React works well for simple, non-interactive components. Complex, interactive components are going to have state. Stateful components don't work so well in React. If you want to update props in a stateful component, the recommendation is to replace the component entirely by changing its key. At the point all of the benefits of React (preservation of selection, caret position, scroll position etc.) vanish. You might as well use vanilla js instead of React.

What does using Vanilla JS look like? Here's an example: https://github.com/wisercoder/eureka It uses two tiny 500-line libs. It uses TSX files, just like React. It has components, just like React. It doesn't have incremental screen update, but neither does React, if your components are interactive and stateful.
