            Default Ripple
        </button>
    );
}

Options

Default options

useRipple({
    duration: 450,
    color: "rgba(255, 255, 255, .3)",
    cancelAutomatically: false,
    timingFunction: "cubic-bezier(.42,.36,.28,.88)",
    disabled: false,
    ref: internalRef,
    onSpawn: undefined,
});

Options reference

Property Description Type Default Optional
duration Duration in milliseconds of the ripple effect number 450 ✔️
color Color of the ripple effect string rgba(255, 255, 255, .3) ✔️
cancelAutomatically If true, the ripple will begin to cancel after 40% of the duration boolean false ✔️
timingFunction Transition timing function of the transform animation string cubic-bezier(.42,.36,.28,.88) ✔️
disabled If true, no ripple will be spawned boolean false ✔️
ref Optional outside ref, if unset, internal ref will be used React.RefObject<T> undefined ✔️
onSpawn A callback which is triggered when a ripple is spawned options.onspawn undefined ✔️

options.onSpawn

Type

type OnSpawnCB = (ctx: {
    /** the ripple element */
    readonly ripple: HTMLDivElement;

    /** cancels the current ripple animation */
    readonly cancelRipple: () => void;

    /** the ref to the ripple host element */
    readonly ref: React.RefObject<T>;
    
    /** the event that triggered the ripple (ts: casting required) */
    readonly event: unknown;
}) => void;

Example

useRipple({
    /* ... */
    onSpawn: ({
      ripple, ref, event  
    }) => {
        console.table({ ripple, ref, event });
    }
});

Perfect circle

As demonstrated in the below GIF, useRipple adjusts the circle size according to always for the host element’s box.

Higher order function (HOF)

If you want to memoize a configuration for your ripple you can use the built in customRipple() function.

You can override the options you memoized for your custom ripple hook. The two options will be merged.

Usage

import { customRipple } from "use-ripple-hook";

const useMyRipple = customRipple({
    color: "rgb(144, 238, 144, .7)",
    duration: 700,
});

function Button() {
    const [ripple, event] = useMyRipple({}); // Optionally override previous config

    return (
        <button ref={ripple} onMouseDown={event}>
            Memoized Ripple
        </button>
    );
}

This is useful if you want to avoid repetition in your code or if you want multiple different ripple effects for different components.

Dos and don’ts

✔ Do this:

Using components 👍

import React from "react";
import useRipple from "use-ripple-hook";

function App() {
    return (
        <>
            <Button color="red" />
            <Button color="yellow" />
        </>
    )
}

function Button({ color }) {
    const [ripple, event] = useRipple({ color });

    return (
        <button ref={ripple} onMouseDown={event}>
            Button
        </button>
    );
}

❌ Don’t do this:

Sharing references 👎

import React from "react";
import useRipple from "use-ripple-hook";

function App() {
    const [ripple, event] = useRipple();

    /* This will NOT work! Do not do this */
    return (
        <>
            <button color="red" ref={ripple} onMouseDown={even}>
                Button
            </button>
            <button color="yellow" ref={ripple} onMouseDown={even}>
                Button
            </button>
        </>
    )
}
