ToggleClass

A component that toggles a class on a target element. The target element can be a ref or a selector.

import { tw } from "twind/core";
import ToggleClass from "https://deno.land/x/tailored/components/ToggleClass.tsx";

export default function MenuButton(props: MenuButtonProps) {
  return (
    <ToggleClass
      target="[mobile-menu]"
      toggleAddClass={tw("flex")}
      toggleRemoveClass={tw("visibility-hidden")}
    >
      <MenuIcon />
    </ToggleClass>
  );
}

LazyHydrate

Hydrate components only when they are in the viewport or when an event is emitted. You can control hydration by emmiting a custom event on the document. By default, the component supports the visible event which is implemented with an intersection observer.

import { tw } from "twind/core";
import LazyHydrate from "https://deno.land/x/tailored/components/LazyHydrate.tsx";

export default function MenuButton(props: MenuButtonProps) {
  return (
    <LazyHydrate
      id="lazy123"
      event="visible"
      classNames={[
        "x-non-hydrated",
        "x-hydrated",
      ]}
    >
      <MyComplexComponent {...props} />
    </LazyHydrate>
  );
}
