$ npm install vue-haptic

// main.js
import Vue from 'vue'
import VueHaptic from 'vue-haptic';
 
Vue.use(VueHaptic, {
  // Required. vue-haptic does not provide
  // any out-of-the-box patterns
  patterns: {
    success: [10, 100, 30],
    failure: [10, 50, 10, 50, 50, 100, 10],
    long: 200,
    default: 10,
  },
});
 
// ...

A pointer-events polyfill is recommended to be used alongside vue-haptic to support older browsers.

Usage

---

<!-- Uses the global "default" pattern (defined by you, see below) -->
<button v-haptic>Vibrate!</button>
 
<!-- Use with a different trigger event -->
<button v-haptic.pointerup>Vibrate!</button>
 
<!-- Use a global pattern preset (see below) -->
<button v-haptic:preset>Vibrate!</button>
<button v-haptic="preset">Vibrate!</button>
 
<!-- Set a one-off pattern on the element -->
<button v-haptic="200">Vibrate!</button>
<button v-haptic="[10,50,10,50,10]">Vibrate!</button>
 
<!-- Use a custom "trigger function"
to control when the haptic feedback occurs -->
<button v-haptic="customTrigger">Vibrate!</button>
 
<!-- Pass options using an object -->
<button
  v-haptic="{
    pattern: [20,100,20],
    trigger: customTriggerFunction | event-name
  }"
>
  Vibrate!
</button>

Pattern Presets

---

Pattern presets are defined globally. You can name them anything that can be used as an argument for a Vue directive.

The "default" preset is special. It is used if you don't specify a preset for v-haptic.

// main.js
Vue.use(VueHaptic, {
  patterns: {
    foo: 200,
    bar: [10, 100, 30],
    // Special
    default: 10,
  },
});

Presets are also available in components as vm.$haptics.patterns

export default {
    //...
    mounted() {
        console.log(this.$haptics.patterns.bar)
        // > [10, 100, 30]
    }
}

Other Global Options

---

defaultHapticTrigger

Use this to configure the default event used to trigger haptic feedback. By default, "pointerdown" is used.

// main.js
Vue.use(VueHaptic, {
  // patterns: {...},
 
  defaultHapticTrigger: 'touchstart',
});

---

disabled

Used to globally disable haptic feedback.
This can also be changed from any component by setting vm.$haptics.disabled.
The default is false (haptics are enabled).

// main.js
Vue.use(VueHaptic, {
  // patterns: {...},
 
  disabled: false,
});

Event Modifiers/Custom Triggers

---

Event modifiers

You can use a directive modifier to change the trigger event for a givin element/component:

<input type="checkbox" v-haptic.change>
<input type="text" v-haptic.input>
<button v-haptic.pointerup>Vibrate!</button>
<!-- etc. -->

This also supports custom events emitted from Vue Components:

<CustomComponent v-haptic.success />

You can use event modifiers and presets at the same time:

<button v-haptic:foo.click>Vibrate!</button>

The trigger event can also be set using the trigger option:

<button v-haptic="{
  trigger: 'click'
}">

---

Custom trigger functions

Custom trigger functions can be used when you need to trigger haptics based on something other than an event. Think of these at lifecycle hooks, in that they are called when the directive is bound an element and allow you to do setup work.

A trigger function as the following signature:

tiggerFunction: (activator: (pattern?) => boolean, el: Element) => void

• activator - a function that, when called, will activate the haptic feedback. It takes a pattern as an optional argument. The pattern can be a number, number[], or the name of a preset. If the pattern is omitted, the preset defined in the markup is used instead (or the default pattern if one is not defined in the markup)
• el - the Element that the directive is bound to.

<input v-haptic="customTrigger" v-model="value" />
<!-- or -->
<input v-haptic="{trigger:customTrigger}" v-model="value" />
 
<script>
  export default {
    data() {
      return { value: '' };
    },
    methods: {
      customTrigger(activate, el) {
        this.$watch('value', value => {
          // When the input's value is "vibrate" the haptics will be triggered.
          if (value === 'vibrate') activate(this.$haptics.patterns.bar);
        });
      },
    },
  };
</script> 

Miscellaneous

cancellationPeriod

Defines the period of time (in milliseconds) after the haptic trigger is fired but before the haptic feedback is actually activated. During this period the haptic feedback will be canceled if the user moves their finger or otherwise causes a "pointercancel" or "touchcancel" event to fire. This option is only applicable if the haptic trigger is "pointerdown" or "touchstart".

Default: 75

<!-- It can be used per-directive -->
<button v-haptic="{
  cancellationPeriod: 100
}">Vibrate!</button>

// or globally
Vue.use(VueHaptic, {
  // patterns: {...},
 
  cancellationPeriod: 100
});

vm.$haptics.cancel()

---

From any component, the vm.$haptics.cancel() method can be called to stop any currently running haptics
