How to Handle Ripple Effects in Material-UI Buttons Using useLazyRipple

Material-UI's useLazyRipple hook defers the creation of the TouchRipple component until the first user interaction, reducing initial render overhead in applications with many buttons.

The useLazyRipple hook is an internal performance optimization in the mui/material-ui repository that controls how ripple animations initialize in button components. By default, Material-UI buttons mount a TouchRipple instance immediately, which can create unnecessary DOM nodes and JavaScript overhead when rendering lists or grids containing dozens of interactive elements.

Understanding the Ripple Architecture in Material-UI

Material-UI implements the ripple effect through a layered architecture centered around the ButtonBase component. When you render a <Button> or <IconButton>, you are actually using a composite built on top of ButtonBase located at packages/mui-material/src/ButtonBase/ButtonBase.tsx.

The visual ripple animation itself is handled by the TouchRipple component in packages/mui-material/src/ButtonBase/TouchRipple.tsx. This component manages the expanding circles and their CSS animations. By default, ButtonBase mounts TouchRipple immediately during the initial render, creating the ripple container in the DOM regardless of whether the user ever interacts with the button.

How useLazyRipple Works

The useLazyRipple hook, implemented in packages/mui-material/src/ButtonBase/useLazyRipple.ts, solves the eager mounting problem through lazy initialization. Instead of creating the TouchRipple instance immediately, the hook returns an initialization function that remains dormant until the first user interaction.

The internal flow follows three distinct stages:

1. Initial render – useLazyRipple returns an initRipple callback and a rippleAction ref. No TouchRipple element exists in the DOM, reducing the initial render footprint.

2. First interaction – When the user triggers mousedown or touchstart, the ButtonBase event handler invokes initRipple(). The hook then creates the TouchRipple instance, inserts it into the DOM, and immediately forwards the ripple start request.

3. Subsequent interactions – The already-mounted TouchRipple component is reused for all future interactions, ensuring the initialization cost is paid only once per button instance.

Implementing useLazyRipple in Your Components

Most developers do not need to manually implement useLazyRipple because Material-UI's standard components already utilize it internally. When you import Button from @mui/material, you are automatically benefiting from the lazy ripple optimization through the ButtonBase inheritance chain.

import * as React from 'react';
import Button from '@mui/material/Button';

// This button automatically uses useLazyRipple via ButtonBase
export default function LazyRippleDemo() {
  return (
    <Button variant="contained" onClick={() => console.log('clicked')}>
      Click Me
    </Button>
  );
}

The lazy initialization occurs transparently in the background, reducing the DOM weight of large button grids without requiring any changes to your application code.

Customizing and Disabling the Ripple Effect

For advanced use cases requiring direct control over the ripple lifecycle, Material-UI exports unstable_useLazyRipple from the ButtonBase module. This hook allows you to build custom button components with the same performance characteristics as the standard library.

The hook returns two critical references:

• initRipple: A callback function that triggers the creation of the TouchRipple instance
• rippleAction: A ref containing methods to control the ripple animation (start, stop, pulsate)

import * as React from 'react';
import ButtonBase from '@mui/material/ButtonBase';
import { unstable_useLazyRipple } from '@mui/material/ButtonBase';

export default function CustomLazyRipple() {
  const rippleRef = React.useRef<any>(null);
  const { initRipple, rippleAction } = unstable_useLazyRipple(rippleRef);

  const handleMouseDown = (event: React.MouseEvent) => {
    // Initialise the ripple on first press
    initRipple();
    rippleAction.current?.start(event);
  };

  return (
    <ButtonBase
      onMouseDown={handleMouseDown}
      ref={rippleRef}
      // Disable default ripple to avoid double-initialisation
      disableRipple
    >
      Custom Button
    </ButtonBase>
  );
}

To completely disable the ripple effect without custom logic, pass the disableRipple prop to any button component. This prevents both the eager mounting and the lazy initialization of the TouchRipple component.

Summary

• useLazyRipple is an internal performance hook in packages/mui-material/src/ButtonBase/useLazyRipple.ts that defers TouchRipple creation until the first user interaction.
• Standard Material-UI buttons automatically benefit from this optimization through the ButtonBase component, requiring no code changes for most applications.
• The hook returns initRipple for triggering initialization and rippleAction for controlling the animation lifecycle, available as unstable_useLazyRipple for custom implementations.
• Use the disableRipple prop to completely suppress ripple effects when the animation is not desired.

Frequently Asked Questions

What is the performance benefit of using useLazyRipple?

The primary benefit is reduced initial render overhead. Without lazy initialization, every button mounts a TouchRipple component immediately, creating DOM nodes and JavaScript objects even for buttons that users never click. In applications with dense button grids or lists, useLazyRipple significantly reduces memory usage and improves Time-to-Interactive metrics by creating these elements only when needed.

Is useLazyRipple stable for production use?

While the hook is used internally by stable components like Button and IconButton, the direct export unstable_useLazyRipple indicates that the hook's API surface may change in future releases without following the standard deprecation cycle. For production applications, rely on the stable component APIs (Button, ButtonBase) rather than importing the hook directly, unless you are prepared to handle potential breaking changes in minor version updates.

How do I disable the ripple effect on specific buttons?

Pass the boolean prop disableRipple to any Material-UI button component. When disableRipple={true} is set, the component skips both eager and lazy initialization of the TouchRipple component, effectively removing the ripple animation. This prop is available on all components that inherit from ButtonBase, including Button, IconButton, Tab, and ListItemButton.

Can I customize the ripple color or animation with useLazyRipple?

The useLazyRipple hook itself does not control visual styling; it only manages the lifecycle and initialization of the TouchRipple component. To customize the ripple appearance, use the TouchRippleProps prop on ButtonBase or override the theme's ripple styling. The TouchRipple component accepts props like center and classes for color customization, which you can pass through ButtonBase even when using the lazy initialization pattern.
