Why did I make this?

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

_{Also available for Vue: v-wave}

Here's what you can expect from this hook:

- 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 effect 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.

If you have a feature request or you found a bug, please open an issue!

Install

npm
``sh
$ npm i use-wave
`
or

CDN
`html

`

Usage

`jsx
import useWave from 'use-wave'

function MyComponent() {
const wave = useWave()

return Click me!
}
`

It is possible to reuse a single wave for multiple elements

`jsx
import useWave from 'use-wave'

function List() {
const wave = useWave()
const items = ['item 1', 'item 2', 'item 2']

return (
<>
Home

{items.map(item =>
• {item}
)}

)
}
`

Options

#### Usage with options

`js
useWave({
color: 'red',
startingOpacity: 0.5,
easing: 'ease-in',
})
`

#### Global options

`js
// your/hooks/directory/use-custom-wave.js

export const useCustomWave = (overrides = {}) => {
const defaults = {color: 'red'} // your custom global options
return useWave({...defaults, ...overrides})
}
`

$3

#### color
- type: string
- default: "currentColor"

The background-color of the wave.

#### initialOpacity
- type: number
- default: 0.2

The opacity of the wave when it first appears.

#### finalOpacity
- type: number
- default: 0.1

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

#### duration
- type: number
- default: 0.4

The duration of the wave animation in seconds.

#### easing
- type: string
- default: "ease-out"

Any valid CSS

#### cancellationPeriod
- type: number
- default: 75`

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

Note:
The wave will not appear until after the delay, meaning a delay greater than 100ms can make the site feel sluggish.
