v-wave

v-wave

The material-ripple directive for Vue that actually works

_{Also available for React: use-wave}

Why did I make this?

Because every ripple plugin I've tried to use in the past either didn't work or was missing basic features.

Here's what you can expect from this plugin:

• It works (see for yourself).
• The wave appears on pointerdown instead of pointerup
  (you might think that's an obvious choice... but you'd be wrong).
• There is a small delay before the ripple appears, during which the animation will be canceled if the user moves the pointer (e.g. scrolling on a mobile phone). This is similar to how native Android ripples work.
• Uses CSS transforms instead of width and height.
• Doesn't affect the appearance of the element you apply it to (won't explode when used on an element with display: flex).
• Guesses the color of the wave automatically by default (using currentColor).
• Works with fixed, absolute, relative, and statically positioned elements.
• Will handle independent border-radii (e.g. border-radius: 5px 20px 15px 30px) perfectly fine.

Quick start

After installing and registering the plugin, this is all you need to get started:

<button v-wave>Click here</button>

Out of the box, this will provide you with a ripple that matches the text color of the element it has been applied to, with reasonable defaults for a responsive feeling ripple.
You can change the look and feel of the ripple on a per-element basis, or by modifying the global defaults.

Details

color

• type: string (background shorthand syntax)
• default: "currentColor"

Sets the background of the ripple.
Supports any value that the CSS background property does.

Simple color

<button v-wave="{
    color: 'red',

<button v-wave="{
    color: 'radial-gradient(closest-side, #fff, #00f, #fff)',

</button>

Image

<button v-wave="{
    color: 'no-repeat url(https://...) 0 0 / cover',
}">
Click here
</button>

initialOpacity

• type: number
• default: 0.2

The opacity of the ripple when it first appears.

Expand examples

See: initialOpacity: 1, initialOpacity: 0

initialOpacity of 1

<button v-wave="{
    initialOpacity: 1,
}">
Click here
</button>

initialOpacity of 0

<button v-wave="{
    initialOpacity: 0,
}">
Click here
</button>

finalOpacity

• type: number
• default: 0.1

The opacity the ripple should be when it has stopped moving.

Expand examples

See: finalOpacity: 1, finalOpacity: 0

finalOpacity of 1

<button v-wave="{
    finalOpacity: 1,
}">
Click here
</button>

finalOpacity of 0

<button v-wave="{
    finalOpacity: 0,
}">
Click here
</button>

duration

• type: number (seconds)
• default: 0.4

The duration of the ripple in seconds.
The total duration is duration + dissolveDuration

Expand example

duration of 3 seconds

<button v-wave="{
    duration: 3,
}">
Click here
</button>

dissolveDuration

• type: number (seconds)
• default: 0.15

The duration of the "dissolve animation" in seconds.
This is the fade-out animation that plays once the wave has reached its maximum size.
The total duration is duration + dissolveDuration

Expand example

dissolve duration of 3 seconds

<button v-wave="{
    dissolveDuration: 3,
}">
Click here
</button>

easing

• type: string (<easing-function>)
• default: "ease-out"

Any valid CSS <easing-function> (see more)

Expand example

cubic-bezier

<button v-wave="{
    easing: 'cubic-bezier(0,.57,.89,0)',
}">
Click here
</button>

cancellationPeriod

• type: number (milliseconds)
• default: 75

The delay, in milliseconds, during which the animation will be canceled if the user moves their figure/pointer (e.g. while scrolling on a mobile device).

Note: The ripple will not appear until after the delay. This means a delay greater than 100ms can feel sluggish.

trigger

• type: "auto" | string | boolean
• default: "auto"

Sets the behavior of the wave when used with triggers. (See the dedication section on triggers for more details).

• false
  Disables the use of triggers. If a v-wave-trigger (without an ID) is present in the dom tree of this element, it will be ignored (i.e. v-wave always behaves as if there's no trigger).

• true
  Requires a trigger to activate the ripple. v-wave assumes the presence of a v-wave-trigger (without an ID) in its dom tree. The ripple will only activate for pointerdown events on the trigger element.

• "auto"
  If a v-wave-trigger (without an ID) is present in the dom-tree of the v-wave element, it behaves as trigger: true, otherwise it behaves as trigger: false.

• string
  Any string other than "auto" will be treated as an ID. v-wave will only activate when a v-wave-trigger with a matching ID receives a pointerdown event.

  This is different from the other values as it allows you to place the trigger element anywhere in the dom, while the others require the trigger to be a descendant.

Expand example

basic trigger

<label v-wave>
  <input type="text" placeholder="Search" />
  
  <!-- Only show the wave when the trigger is clicked -->
  <img v-wave-trigger src="search.svg" />
</label>

tagName

• type: string
• default: "div"

Sets the tag name of the element used as the wave container. This is is useful in scenarios where the default div may interfere with :last-of-type or similar selectors.

Using triggers

Triggers allow you to activate a wave on an element when, and only when, a different element receives input.

In the following example, the wave will only activate for the label element when the user clicks or taps on the <img/>.

<label v-wave>
    <span>Password</span>
    <input :type="showPassword ? 'text' : 'password'" />
    <img v-wave-trigger src="eye.svg" @click="() => showPassword = !showPassword" />
</label>

In this next example, clicking one of the buttons will activate the wave on the other button.

<button v-wave="{trigger: 'button2'}" v-wave-trigger:button1>Button 1</button>

<button v-wave="{trigger: 'button1'}" v-wave-trigger:button2>Button 2</button>

Triggers that use an ID support many-to-many relationships. See the grid example on the example page.

Disabling the directive

If you need to temporarily disable the wave effect, simply pass false to the directive.

Note that v-wave checks for strict false equality (=== false).
Using any other falsely value will not disable the directive.

<button v-wave="false">Click me!</button>

Advanced

Registering the directive locally

Local registration with Composition API:

<script>
import VWave from 'v-wave'
const { vWave, vWaveTrigger } = VWave.createLocalWaveDirective({/* global options */})
</script>

<template>
   <button v-wave>Click me!</button>
</template>

Local registration with Options API:

<script>
import VWave from 'v-wave'
const { wave, waveTrigger } = VWave.createLocalWaveDirective({/* global options */})

export default {
  directives: {
      wave,
      waveTrigger
  }
}
</script>

<template>
  <button v-wave>Click me!</button>
</template>

Vue 2

If you are using Vue 2, you need to pass "vue2" as the second argument to createLocalWaveDirective

<script>
import VWave from 'v-wave'
const { wave, waveTrigger } = VWave.createLocalWaveDirective({/* global options */}, 'vue2') // this is the difference

export default {
  directives: {
      wave,
      waveTrigger
  }
}
</script>

<template>
  <button v-wave>Click me!</button>
</template>

Changing the directive's name

If you are migrating from another ripple directive you can change the name of the directive v-wave uses if you want to avoid changing it in your source code.
Simply pass a new name for the directive using the directive option:

//main.js

import Vue from 'vue'
import VWave from 'v-wave'

Vue.use(VWave, {
    directive: 'ripple'
})

Now you can use the plugin like so:

<button v-ripple>Click me!</button>

Keep in mind that this option can only be set globally (i.e. it cannot be set on individual directives).
