useCounter

A hook that returns a signal with a counter value and functions to increment, decrement, set and reset the counter.

import { useCounter } from 'bagon-hooks';

export function UseCounterExample() {
  const [count, { decrement, increment, reset, set }] = useCounter(5, { min: 1, max: 10 });

  return (
    <div class="flex h-full w-full flex-col items-center justify-center gap-5 gap-x-1 rounded-md border p-3 py-10 text-center">
      <span>{count()}</span>

      <div class="flex gap-x-2 text-sm">
        <button class="rounded-md border p-1 px-1.5 transition active:scale-90" onClick={decrement}>
          -
        </button>
        <button class="rounded-md border p-1 px-1.5 transition active:scale-90" onClick={increment}>
          +
        </button>
        <button class="rounded-md border p-1 px-1.5 transition active:scale-90" onClick={reset}>
          Reset
        </button>
        <button
          class="rounded-md border p-1 px-1.5 transition active:scale-90"
          onClick={() => set(Math.floor(Math.random() * 10))}
        >
          Set (To Random)
        </button>
      </div>
    </div>
  );
}

useOs

Returns the current OS

Current OS: undetermined

import { useOs } from 'bagon-hooks';

export function UseOsExample() {
  const os = useOs();

  return (
    <div class="flex h-full w-full items-center justify-center rounded-md border p-3 py-10 text-center">
      Current OS: {os()}
    </div>
  );
}

useClickOutside

Detects clicks outside a ref

No detections

import { useClickOutside } from 'bagon-hooks';

import { createSignal, Show } from 'solid-js';

export function UseClickOutsideExample() {
  const ref = useClickOutside(() => {
    setClicked(true);

    setTimeout(() => {
      setClicked(false);
    }, 500);
  });
  const [clicked, setClicked] = createSignal(false);

  return (
    <div class="flex h-full w-full flex-1 items-center justify-center rounded-md border p-3 py-10">
      <div
        class={`select-none rounded-full border bg-neutral-50 p-2 text-xs transition ${clicked() ? 'scale-95' : ''}`}
        ref={ref}
      >
        <Show when={clicked()} fallback={'No detections'}>
          You clicked outside!
        </Show>
      </div>
    </div>
  );
}

useHotkeys

Handle hotkeys easily

ctrl + a

ctrl + Enter

shift + g

import { useHotkeys, useOs } from 'bagon-hooks';

import { createSignal, FlowProps, VoidProps } from 'solid-js';

export function UseHotkeysExample() {
  const [activatedHotkey, setActivatedHotkey] = createSignal<-1 | 0 | 1 | 2>(-1);

  let timeout: ReturnType<typeof window.setTimeout>;

  function handleKeyPress(index: ReturnType<typeof activatedHotkey>) {
    if (timeout) clearTimeout(timeout);

    setActivatedHotkey(index);

    timeout = setTimeout(() => {
      setActivatedHotkey(-1);
    }, 400);
  }

  useHotkeys([
    ['mod+a', () => handleKeyPress(0)],
    ['mod+Enter', () => handleKeyPress(1)],
    ['shift+g', () => handleKeyPress(2)],
  ]);

  const os = useOs();

  return (
    <div class="flex h-full w-full flex-wrap items-center justify-center gap-3 rounded-md border p-3 py-10 text-center">
      <Key activated={activatedHotkey() === 0}>{os() === 'macos' ? 'cmd' : 'ctrl'} + a</Key>
      <Key activated={activatedHotkey() === 1}>{os() === 'macos' ? 'cmd' : 'ctrl'} + Enter</Key>
      <Key activated={activatedHotkey() === 2}>shift + g</Key>
    </div>
  );
}

function Key(props: FlowProps<{ activated: boolean }>) {
  return (
    <div class="relative text-xs">
      <div class="absolute inset-0 rounded-md bg-neutral-200 transition"></div>
      <div
        class="relative transform rounded-md border bg-neutral-50 px-2 py-1.5 transition-transform"
        style={{
          transform: props.activated ? 'translateY(0px)' : 'translateY(-5px)',
        }}
      >
        {props.children}
      </div>
    </div>
  );
}

useKeyboard

Use this for more general keyboard events, as opposed to useHotkeys.

import { useKeyboard } from 'bagon-hooks';

import { createStore } from 'solid-js/store';

export function UseKeyboardExample() {
  const [store, setStore] = createStore({ a: false, b: false, c: false, d: false });

  useKeyboard({
    onKeyDown(event) {
      // Refactor this into if statements.
      if (event.key === 'a') {
        setStore('a', true);
      } else if (event.key === 'b') {
        setStore('b', true);
      } else if (event.key === 'c') {
        setStore('c', true);
      } else if (event.key === 'd') {
        setStore('d', true);
      }
    },
    onKeyUp(event) {
      // Refactor this into if statements.
      if (event.key === 'a') {
        setStore('a', false);
      } else if (event.key === 'b') {
        setStore('b', false);
      } else if (event.key === 'c') {
        setStore('c', false);
      } else if (event.key === 'd') {
        setStore('d', false);
      }
    },
  });

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-center">
      <Kbd activated={store.a}>a</Kbd>
      <Kbd activated={store.b}>b</Kbd>
      <Kbd activated={store.c}>c</Kbd>
      <Kbd activated={store.d}>d</Kbd>
    </div>
  );
}

useHover

Detects hovers on a ref

No detections

import { useClickOutside, useHover } from 'bagon-hooks';

import { createSignal, Show } from 'solid-js';

export function UseHoverExample() {
  const { ref, hovered } = useHover();

  return (
    <div class="flex h-full w-full flex-1 items-center justify-center rounded-md border p-3 py-10">
      <div
        class={`cursor-pointer select-none rounded-full border bg-neutral-50 p-2 text-xs transition ${hovered() ? 'scale-95' : ''}`}
        ref={ref}
      >
        <Show when={hovered()} fallback={'No detections'}>
          You hovered me!
        </Show>
      </div>
    </div>
  );
}

useIdle

Returns if user has been idle after some milliseconds

Is Idle (1s):true

import { useIdle, useOs } from 'bagon-hooks';

import { Show } from 'solid-js';

export function UseIdleExample() {
  const idle = useIdle(1000);

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-center">
      <span>Is Idle (1s):</span>
      <Show
        when={idle()}
        fallback={
          <span>
            <span class="text-green-500">false</span>
          </span>
        }
      >
        <span class="text-red-500">true</span>
      </Show>
    </div>
  );
}

useId

Returns a random id.

Random ID: 00001001070

import { useId } from 'bagon-hooks';

export function UseIdExample() {
  const id = useId();

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-center text-sm">
      Random ID: <span class="rounded-md bg-neutral-300 px-1.5 py-0.5">{id()}</span>
    </div>
  );
}

useMounted

Returns true if component is mounted. Useful for rendering only on client-side.

import { useIdle, useMounted, useOs } from 'bagon-hooks';

import { Show } from 'solid-js';

export function UseMountedExample() {
  const mounted = useMounted();

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-center">
      <Show when={mounted()}>This only shows on the client.</Show>
    </div>
  );
}

useNetwork

Returns information about current user's network connection. Try going offline on DevTools.

{
  "online": true
}

import { useIdle, useNetwork, useOs } from 'bagon-hooks';

export function UseNetworkExample() {
  const networkStatus = useNetwork();

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-start">
      <pre
        class={`rounded-md border p-3 px-5 ${networkStatus().online ? 'bg-neutral-100' : 'border-red-500 bg-red-200'}`}
      >
        {JSON.stringify(networkStatus(), null, 2)}
      </pre>
    </div>
  );
}

useResizeObserver

Returns information about a resizable element. This is more low-level but gives you more than just width and height.

{
  "rect": {
    "x": 0,
    "y": 0,
    "width": 0,
    "height": 0,
    "top": 0,
    "left": 0,
    "bottom": 0,
    "right": 0
  }
}

Resize Me

import { useIdle, useNetwork, useOs, useResizeObserver } from 'bagon-hooks';

export function UseResizeObserverExample() {
  const [ref, rectStore] = useResizeObserver();

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-3 rounded-md border p-3 py-10 text-start">
      <pre class={`rounded-md border bg-neutral-100 p-3 px-5 text-xs`}>
        {JSON.stringify(rectStore, null, 2)}
      </pre>

      <div class="relative grid place-items-center overflow-hidden">
        <textarea ref={ref} class="h-20 w-20 resize rounded-md border"></textarea>
        <div class="pointer-events-none absolute inset-0 grid place-items-center truncate text-xs text-neutral-400">
          Resize Me
        </div>
      </div>
    </div>
  );
}

useElementSize

Returns width and height of a resizable element. An abstraction over useResizeObserver.

Width: 0.00Height: 0.00

Resize Me

import { useElementSize, useIdle, useNetwork, useOs, useResizeObserver } from 'bagon-hooks';

export function UseElementSizeExample() {
  const { ref, height, width } = useElementSize();

  return (
    <div class="flex h-full w-full flex-col items-center justify-center gap-3 rounded-md border p-3 py-10 text-start">
      <div class="flex flex-col items-center">
        <span>Width: {width().toFixed(2)}</span>
        <span>Height: {height().toFixed(2)}</span>
      </div>

      <div class="relative grid flex-1 place-items-center overflow-hidden">
        <textarea ref={ref} class="h-20 w-20 resize rounded-md border"></textarea>
        <div class="pointer-events-none absolute inset-0 grid place-items-center truncate text-center text-xs text-neutral-400">
          Resize Me
        </div>
      </div>
    </div>
  );
}

useToggle

A hook that toggles between two or multiple values (by implementing a common state pattern). Dev Note: Personally this can be called `useCycle` instead since it cycles through the options.

🍎 apple

🍊 orange

🍇 grape

🥝 kiwi

import { useToggle } from 'bagon-hooks';

import { createMemo, FlowProps } from 'solid-js';

export function UseToggleExample() {
  const [value, toggle] = useToggle(['apple', 'orange', 'grape', 'kiwi'] as const);

  const color = createMemo(() => {
    if (value() === 'apple') return '#e5312f';
    if (value() === 'orange') return '#fc8627';
    if (value() === 'grape') return '#bc3d73';
    if (value() === 'kiwi') return '#acc144';

    return undefined;
  });

  return (
    <div
      class="flex h-full w-full flex-col items-center justify-center gap-3 rounded-md border p-3 py-10 text-center transition-colors"
      style={{
        'background-color': color(),
      }}
    >
      <div class="flex flex-wrap gap-3">
        <Key activated={value() === 'apple'}>🍎 apple</Key>
        <Key activated={value() === 'orange'}>🍊 orange</Key>
        <Key activated={value() === 'grape'}>🍇 grape</Key>
        <Key activated={value() === 'kiwi'}>🥝 kiwi </Key>
      </div>

      <button onClick={() => toggle()} class="text-white transition active:scale-95">
        Click me to Toggle
      </button>
    </div>
  );
}

function Key(props: FlowProps<{ activated: boolean }>) {
  return (
    <div class="relative text-xs">
      <div class="absolute inset-0 rounded-md bg-neutral-200 transition"></div>
      <div
        class="relative transform rounded-md border bg-neutral-50 px-2 py-1.5 transition-transform"
        style={{
          transform: props.activated ? 'translateY(0px)' : 'translateY(-5px)',
        }}
      >
        {props.children}
      </div>
    </div>
  );
}

useFavicon

Appends <link /> element to head component with given favicon url. The hook is not called during server side rendering.

import { useFavicon } from 'bagon-hooks';

import { createSignal } from 'solid-js';

/** Improved Bagon implementation - You can choose to set it when you want. */
export function UseFaviconExample() {
  const [_favicon, setFavicon] = useFavicon(); // The secret is: just don't pass an accessor in the hook.

  const setXFavicon = () => {
    setCurrentIcon('x');
    setFavicon('https://x.com/favicon.ico');
  };
  const setSolidFavicon = () => {
    setCurrentIcon('solid');
    setFavicon('https://docs.solidjs.com/favicon.svg');
  };

  return (
    <div class="relative flex h-full w-full flex-col items-center justify-center gap-3 overflow-hidden rounded-md border p-3 py-10 text-center text-sm">
      <IconSolidJS
        class="absolute -bottom-10 -right-10 h-48 w-48 rotate-45 transition"
        style={{ opacity: currentIcon() === 'solid' ? 1 : 0 }}
      />
      <IconX
        class="absolute -bottom-10 -right-10 h-48 w-48 rotate-45 transition"
        style={{ opacity: currentIcon() === 'x' ? 1 : 0 }}
      />

      <button
        onClick={() => {
          setXFavicon();
        }}
        class="relative rounded-md border bg-white px-2 py-1.5 transition active:scale-95"
      >
        X favicon
      </button>

      <button
        onClick={() => {
          setSolidFavicon();
        }}
        class="relative rounded-md border bg-white px-2 py-1.5 transition active:scale-95"
      >
        Solid favicon
      </button>
    </div>
  );
}

/** Based on Mantine's implementation - it always runs onMount. */
export function UseFaviconExampleMantine() {
  const [favicon, setFavicon] = createSignal('https://docs.solidjs.com/favicon.svg');
  const setXFavicon = () => setFavicon('https://x.com/favicon.ico');
  const setSolidFavicon = () => setFavicon('https://docs.solidjs.com/favicon.svg');

  useFavicon(favicon); // Will always run at the start.

  return (
    <>
      <button onClick={setXFavicon}>Use X Favicon</button>
      <button onClick={setSolidFavicon}>Use SolidJS Favicon</button>
    </>
  );
}

useLocalStorage

A hook that allows using value from the localStorage as a signal. The hook works exactly the same way as createSignal, but also writes the value to the localStorage. It even works between tabs!

To test, try changing the value with two tabs open.

Favorite Fruit: apple

import { useLocalStorage } from 'bagon-hooks';

import { FlowProps } from 'solid-js';

export function UseLocalStorageExample() {
  const [value, setValue] = useLocalStorage({
    key: 'favorite-fruit',
    defaultValue: 'apple',
  });

  return (
    <div class="flex h-full w-full flex-col items-center justify-center gap-3 rounded-md border p-3 py-10 text-center transition-colors">
      <div class="flex flex-wrap gap-3">
        <Key activated={value() === 'apple'} onClick={() => setValue('apple')}>
          🍎 apple
        </Key>
        <Key activated={value() === 'orange'} onClick={() => setValue('orange')}>
          🍊 orange
        </Key>
        <Key activated={value() === 'grape'} onClick={() => setValue('grape')}>
          🍇 grape
        </Key>
        <Key activated={value() === 'kiwi'} onClick={() => setValue('kiwi')}>
          🥝 kiwi{' '}
        </Key>
      </div>

      <span class="text-sm text-neutral-500">Favorite Fruit: {value()}</span>
    </div>
  );
}

function Key(props: FlowProps<{ activated: boolean; onClick: () => void }>) {
  return (
    <button onClick={props.onClick} class="relative text-xs">
      <div class="absolute inset-0 rounded-md bg-neutral-200 transition"></div>
      <div
        class="relative transform rounded-md border bg-neutral-50 px-2 py-1.5 transition-transform"
        style={{
          transform: props.activated ? 'translateY(0px)' : 'translateY(-5px)',
        }}
      >
        {props.children}
      </div>
    </button>
  );
}

useLocalStorageStore

(Improvement) A hook that allows using value from the localStorage as a store for complex and efficient state management. The hook works exactly the same way as createStore, but also writes the value to the localStorage. It even works between tabs!

To test, try changing the value with two tabs open.

import { useLocalStorageStore } from 'bagon-hooks';

import { For } from 'solid-js';
import { produce } from 'solid-js/store';

export function UseLocalStorageStoreExample() {
  const [value, setValue] = useLocalStorageStore<{ id: string; name: string }[]>({
    key: 'todos-store',
    defaultValue: [],
  });

  return (
    <div class="flex h-full w-full flex-col items-center justify-center gap-3 rounded-md border p-3 py-10 text-center transition-colors">
      <For each={value}>
        {(todo, index) => (
          <div class="flex flex-wrap items-center gap-1 text-sm">
            <input
              class="rounded-md border p-1"
              value={todo.name}
              onInput={event => {
                setValue(
                  produce(_value => {
                    if (!_value[index()]) return;
                    _value[index()]!.name = event.target.value ?? '';
                  }),
                );
              }}
            />
            <button
              onClick={() => {
                setValue(
                  produce(_value => {
                    _value.splice(index(), 1);
                  }),
                );
              }}
            >
              <IconClose width={18} height={18} />
            </button>
          </div>
        )}
      </For>

      <button
        class={`rounded-md bg-primary px-3 py-1.5 text-white transition active:scale-95`}
        onClick={() => {
          setValue(
            produce(_value => {
              _value.push({ id: Math.random().toString(), name: 'New Todo' });
            }),
          );
        }}
      >
        New Todo
      </button>
    </div>
  );
}

useEyeDropper

A hook that gives you the ability to open the browser's EyeDropper API and save it to a signal.

Picked Color:

import { useEyeDropper } from 'bagon-hooks';

import { Show } from 'solid-js';

export function UseEyeDropperExample() {
  const { color, supported, pickColor } = useEyeDropper();

  return (
    <div class="flex h-full w-full flex-col items-center justify-center gap-5 rounded-md border p-3 py-10 text-center">
      <div class="flex items-center gap-x-2">
        <button class="transition active:scale-95" onClick={pickColor} disabled={!supported()}>
          <IconEyeDropper />
        </button>

        <div class="flex items-center gap-x-2 text-sm">
          Picked Color: {color()}
          <div class="h-8 w-8 rounded-full border" style={{ 'background-color': color() }} />
        </div>
      </div>

      <Show when={supported() !== undefined && !supported()}>
        <span class="text-xs text-red-500">Your browser does not support EyeDropper.</span>
      </Show>
    </div>
  );
}

useFullscreen

A hook that allows you to enter and exit fullscreen mode. Can also optionally pass a ref of the element to be fullscreened.

import { useFullscreen } from 'bagon-hooks';

import { Show } from 'solid-js';

export function UseFullScreenExample() {
  const { fullscreen, toggle } = useFullscreen();

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-center">
      <button
        class={`rounded-md px-3 py-1.5 text-white transition active:scale-95 ${fullscreen() ? 'bg-red-500' : 'bg-primary'}`}
        onClick={toggle}
      >
        <Show when={fullscreen()} children={'Exit Fullscreen'} fallback={'Enter Fullscreen'} />
      </button>
    </div>
  );
}

useHash

A hook that allows you to get and set the hash value of the current URL like a signal.

  const visible = useDocumentVisibility();

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-center text-sm">
      <div class="flex items-center gap-x-1">

    </div>
  );
}

useIntersection

Obscured

import { useIntersection } from 'bagon-hooks';

import { Show } from 'solid-js';

export function UseIntersectionExample() {
  const { ref, entry } = useIntersection({
    threshold: 0.75, // At least 75% of the element must "intersect" with the viewport

        </div>
      </div>
    </div>
  );
}

useInputState

Handles state of native inputs with the onChange or onInput handlers. Syntax sugar over writing your own handler functions and types for the events.

You can treat this as the SolidJS way of Svelte's ease of use with `bind:value` and `bind:checked`

{"input":"","checkbox":false}

import { useInputState } from 'bagon-hooks';

export function UseInputStateExample() {
  const [input, handleInput] = useInputState('');
  const [checkbox, handleCheckbox] = useInputState(false);

  return (
    <div class="flex h-full w-full flex-col items-center justify-center gap-x-1 gap-y-2 rounded-md border p-3 py-10 text-center text-sm">
      <pre class="rounded bg-neutral-200 p-1 text-xs">
        {JSON.stringify({
          input: input(),
          checkbox: checkbox(),
        })}
      </pre>
      <input value={input()} onInput={handleInput} class="rounded-md border p-2" />
      <input
        type="checkbox"
        checked={checkbox()}
        onChange={handleCheckbox}
        class="rounded-md border p-2"
      />
    </div>
  );
}

useDebouncedCallback

Creates a debounced version of a callback function, delaying its execution until a specified time has elapsed since the last invocation.

import { useDebouncedCallback } from 'bagon-hooks';

import { createSignal, For, JSX, Show } from 'solid-js';

function getSearchResults(query: string): Promise<{ id: number; title: string }[]> {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve(
        query.trim() === ''
          ? []
          : Array(5)
              .fill(0)
              .map((_, index) => ({ id: index, title: `${query} ${index + 1}` })),
      );
    }, 1000);
  });
}

export function UseDebouncedCallbackExample() {
  const [search, setSearch] = createSignal('');
  const [searchResults, setSearchResults] = createSignal<{ id: number; title: string }[]>([]);
  const [loading, setLoading] = createSignal(false);

  const debouncedSearch = useDebouncedCallback(async (query: string) => {
    setLoading(true);
    setSearchResults(await getSearchResults(query));
    setLoading(false);
  }, 500);

  const handleInput: JSX.EventHandler<HTMLInputElement, InputEvent> = event => {
    setSearch(event.currentTarget.value);
    debouncedSearch(event.currentTarget.value);
  };

  return (
    <div class="flex h-full w-full flex-col items-center justify-center gap-x-1 gap-y-2 rounded-md border p-3 py-10 text-center text-sm">
      <input
        value={search()}
        onInput={handleInput}
        class="rounded-md border p-2"
        placeholder="Search..."
      />

      <Show
        when={loading()}
        children={<>Loading...</>}
        fallback={
          <For each={searchResults()}>{result => <div class="text-xs">{result.title}</div>}</For>
        }
      />
    </div>
  );
}

useDidUpdate

This hook works the same way as createEffect but it is not called when component is mounted.

Unlike createEffect, this always has a dependency of signals (like React's useEffect) for the reason that the only way to do this in Solid is using the on() + defer property under the hood.

This logs "Did Update X" to the console. Notice that it doesn't log "Did Update 0" since it happens on mount.

import { useDidUpdate } from 'bagon-hooks';

import { createSignal } from 'solid-js';

export function UseDidUpdateExample() {
  const [signal, setSignal] = createSignal(0);

  useDidUpdate(() => {
    console.log('Did Update', signal());
  }, signal);

  return (
    <div class="flex h-full w-full flex-col items-center justify-center gap-x-1 gap-y-2 rounded-md border p-3 py-10 text-center text-sm">
      <p class="max-w-xs text-center text-xs">
        This logs "Did Update {signal() === 0 ? 'X' : signal()}" to the console. Notice that it
        doesn't log "Did Update 0" since it happens on mount.
      </p>
      <button
        class="rounded-md bg-primary p-2 text-white transition active:scale-95"
        onClick={() => {
          setSignal(signal() + 1);
        }}
      >
        Simulate an Update {signal()}
      </button>
    </div>
  );
}

useColorScheme

A hook that returns system color scheme value i.e. either `dark` or `light`.

Your system color scheme is: light

import { useColorScheme } from 'bagon-hooks';

export function UseColorSchemeExample() {
  const colorScheme = useColorScheme();

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-center text-sm">
      <div
        class="rounded-md border px-4 py-2 text-sm"
        style={{
          background: colorScheme() === 'dark' ? '#000' : '#fff',
          color: colorScheme() ? '#fff' : '#000',
        }}
      >
        Your system color scheme is: {colorScheme()}
      </div>
    </div>
  );
}

useDocumentTitle

Sets the `document.title`. Hook is not called during server-side rendering. Only use this for client-only applications.

Home

About

Awesome

import { useDocumentTitle, useToggle } from 'bagon-hooks';

export function UseDocumentTitleExample() {
  const [title, setTitle] = useDocumentTitle();
  const [_, cycle] = useToggle(['Home', 'About', 'Awesome']);

  function _cycle() {
    cycle();
    setTitle(_() as any);
  }
  return (
    <div class="flex h-full w-full flex-col items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-center text-sm">
      <div class="flex flex-col items-center gap-y-7">
        <div class="flex items-center gap-x-2">
          <Kbd activated={title() === 'Home'}>Home</Kbd>
          <Kbd activated={title() === 'About'}>About</Kbd>
          <Kbd activated={title() === 'Awesome'}>Awesome</Kbd>
        </div>
        <button onClick={_cycle}>Toggle</button>
      </div>
    </div>
  );
}

useDisclosure

A simple hook to manage state for dialogs, modals, accordions, etc. Anything that needs to open/close/toggle.

import { useDisclosure } from 'bagon-hooks';

import { Show } from 'solid-js';

export function UseDisclosureExample() {
  const [opened, handlers] = useDisclosure(false);

  return (
    <div class="flex h-full w-full items-center justify-center gap-x-1 rounded-md border p-3 py-10 text-center text-sm">
      <button onClick={handlers.open} class="rounded bg-blue-500 px-4 py-2 text-white">
        Open Dialog
      </button>

      <Show when={opened()}>
        <div class="fixed inset-0 flex items-center justify-center bg-black bg-opacity-50">
          <div class="rounded-lg bg-white p-6 shadow-lg">
            <h2 class="mb-4 text-lg font-bold">Dialog Title</h2>
            <p class="mb-4">This is an example dialog using useDisclosure</p>
            <button onClick={handlers.close} class="rounded bg-gray-500 px-4 py-2 text-white">
              Close
            </button>
          </div>
        </div>
      </Show>
    </div>
  );
}
