Kitchen Action Log

No actions recorded yet. Interact with the demos below.

$el: The Chef Station

Analogy: A chef's personal workspace. $el gives direct access to the component's root element, allowing it to modify itself.

Chef Antoine's Station

Status:

Code Example:

<div x-data="chefStation">
  <!-- ... -->
</div>

Alpine.data('chefStation', () => ({
  status: 'Tidy',
  clean() {
    this.status = 'Immaculate';
    // this.$el refers to the div above
    this.$el.classList.add('bg-green-100');
  },
  // ...
}))

$refs: Named Equipment

Analogy: Using specific, named equipment from anywhere in the kitchen. $refs lets you access any element marked with x-ref from within the component.

Control Panel

Mixer

Off

Oven

Off

Code Example:

<div x-data="kitchen">
  <button @click="operate('mixer')">
    Use Mixer
  </button>
  <div x-ref="mixer">...</div>
</div>

Alpine.data('kitchen', () => ({
  operate(name) {
    // this.$refs.mixer refers to the div
    const el = this.$refs[name];
    el.classList.add('bg-blue-200');
  }
}))

$root: The Entire Kitchen

Analogy: A kitchen-wide event, like a fire alarm. $root refers to the top-level element of the current component, affecting its entire scope.

Kitchen Management

Overall Status:

Notice the red pulsing border on the entire kitchen area when the alarm sounds.

Code Example:

<div x-data="kitchen">
  <!-- Deeply nested button -->
  <button @click="soundAlarm()">
    Alarm
  </button>
</div>

Alpine.data('kitchen', () => ({
  soundAlarm() {
    // this.$root is the component's top div
    this.$root.classList.add('emergency');
  }
}))
