Tooltip

Headless tooltip store. Hover/focus triggers, open/close delays, Escape dismiss. Pair with @alpinejs/anchor for placement.

Install

pnpm add @ailuracode/alpine-tooltip @ailuracode/alpine-core alpinejs

Positioning (Floating UI via Alpine):

pnpm add @alpinejs/anchor

Quick start

import Alpine from "alpinejs";
import { tooltipPlugin } from "@ailuracode/alpine-tooltip";

Alpine.plugin(tooltipPlugin());
Alpine.start();

Store API

Method	Description
`open(id)` / `close(id)` / `toggle(id)`	Visibility
`isOpen(id)`	Open state
`register(id, options?)`	Configure delays and lifecycle callbacks
`showOnHover(id)` / `hideOnHover(id)`	Hover helpers
`showOnFocus(id)` / `hideOnFocus(id)`	Focus helpers
`handleKeydown(id, event)`	Escape dismiss

Option	Default	Description
`openDelay`	`0`	ms before opening on hover/focus
`closeDelay`	`0`	ms before closing on mouseleave/blur
`onOpen` / `onClose`	—	Lifecycle callbacks

Architecture

TooltipController owns all mutable tooltip state. The Alpine plugin copies snapshots into $store.tooltip.instances on each change event. Mutating store snapshots directly does not change controller state.

Avoiding name collisions

If your application already owns a $store.tooltip — or another toolkit plugin registers on that name — rename the integration surface without touching the controller:

Alpine.plugin(tooltipPlugin({ storeKey: "hints" })); // → $store.hints

The exposed constant DEFAULT_TOOLTIP_STORE_KEY keeps the rename discoverable from TypeScript.

Standalone usage (no Alpine)

import {
  createTooltipController,
  createTooltipStore,
  createTooltipStoreFromController,
} from "@ailuracode/alpine-tooltip";

const controller = createTooltipController();
controller.register("help", { openDelay: 150 });
controller.open("help");

const store = createTooltipStore();
// or: createTooltipStoreFromController(controller)

Controller API	Description
`hasInstance(id)`	Whether a tooltip id is registered
`snapshotInstances()`	Shallow readonly copies for adapter sync
`isOpen(id)`	Query open state

Migration

Removed / changed	Replacement
`controller.instances` getter	`snapshotInstances()` or `hasInstance(id)`
`controller.toStore()`	`createTooltipStore()` or `createTooltipStoreFromController(controller)`

Basic markup

<div
  x-data
  x-init="$store.tooltip.register('help', { openDelay: 150 })"
  @keydown.window="$store.tooltip.isOpen('help') && $store.tooltip.handleKeydown('help', $event)"
>
  <button
    x-ref="helpAnchor"
    @mouseenter="$store.tooltip.showOnHover('help')"
    @mouseleave="$store.tooltip.hideOnHover('help')"
    @focus="$store.tooltip.showOnFocus('help')"
    @blur="$store.tooltip.hideOnFocus('help')"
    aria-describedby="help-tooltip"
  >
    Help
  </button>

  <template x-teleport="body">
    <div
      id="help-tooltip"
      x-show="$store.tooltip.isOpen('help')"
      x-anchor.top.fixed.offset.8="$refs.helpAnchor"
      role="tooltip"
      class="z-50"
    >
      Tooltip content
    </div>
  </template>
</div>

SSR

Delays require client-side timers — initialize on the client via x-init.

Limitations

Placement is your responsibility — use @alpinejs/anchor (x-anchor.*.fixed) for flip, shift, and scroll tracking
Use <template x-teleport="body"> + x-anchor.fixed when the floating node sits inside overflow-hidden ancestors
Wire @keydown.window while open so Escape works when focus stays on the trigger
