Re:How Does React Tell a Class from a Function? by prossercj on Monday December 03, 2018 @08:40AM (#18588628)
That post has changed my opinion about hooks. I find this gist especially compelling:

Without hooks, that example would require adding a method (or two) to the component class. With custom hooks, that code can go into a separate module.

Component bloat has been a problem for us, and if hooks can enable components to focus solely on render logic, I'd say that's an improvement.

Can't you achieve the same result by leaving only view logic in the component, and having the data-related logic, including the fact that data has changed in a way that may require redraw, handled in a separate object? Here's how I'd do it in Mithril/TSX:

    class WidthStore {
        width: stream.Stream<number>;
        constructor() {
            this.width = stream(window.innerWidth);
            window.addEventListener('resize', () => {
                this.width(window.innerWidth);
                m.redraw();
            });
        }
    }

    const widthStore: WidthStore = new WidthStore();

    class MyResponsiveComponent {
        view(vnode) {
            return <p>Window width is {widthStore.width()}</p>;
        }
    }
