useRipple is a React Hook that adds an animated ripple effect to a clicked element.
npm install useripple
@keyframes useRippleAnimation {
to {
transform: scale(15);
opacity: 0;
}
}☝️This is the animation that ripples use to ripple. It makes them grow and then disappear. Tweak it however you want and add to your stylesheet.
import React from 'react'
import useRipple from 'useripple'
function App() {
const [
addRipple, // Attach this to any mouse event listener
ripples // Render this to see the ripples
] = useRipple({
// You can pass ripples` CSS here (no worries, it's optional)
background: 'pink'
})
// Look how simple it is!
return (
<div onClick={addRipple} style={{ position: 'relative', overflow: 'hidden' }}>
{ripples}
Look at them ripplin'!
</div>
)
}Q: Where should I attach addRipple?
A: Any MouseEvent listener will do, but your first bet is onClick, onMouseDown or onMouseUp.
Q: What if I want to do something more in my mouse event handler than just add ripples?
A: That's simple! Instead of doing <div onClick={addRipple}> do <div onClick={handleClick}> and then declare handleClick function:
function handleClick(event) {
console.log("I'm gonna ripple!") // 👈 Do anything you want here
addRipple(event) // Don't forget to feed `addRipple` with `event` 👌
}Q: What is ripples variable?
A: It's an array that gets filled with ripple components anytime you call addRipple function with a valid MouseEvent. Each ripple is an absolutely positioned <div>, so make sure their container has position: relative; or something other than default static (overflow: hidden; may come in handy too).
Q: What styles can I attach to ripples?
A: Anything that's valid in React terms. See here what styles do ripples use. These are probably the ones you may want to override. If you want to override animationName, make sure you change it in Step 2 as well.
Enjoy! 💙
