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.

Expand examples

See: color, gradient, image

Simple color

<button v-wave="{
    color: 'red',
}">
Click here
</button>

Gradient

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

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).
