is set to fade
. Default value is 1
.
slidesToShow
A number
to set the amount of slides to show at once. This prop is will be cast as an integer when animation
is set to fade

Default Controls Configuration
A configuration object to apply custom classes and styles to the default container, navigation buttons, and progress dot controls. This configuration object also lets you add additional event handlers to each of the navigation item's click handlers.
interface DefaultControlsConfig {
containerClassName?: string
nextButtonClassName?: string
nextButtonStyle?: CSSProperties
nextButtonText?: React.ReactNode
pagingDotsClassName?: string
pagingDotsContainerClassName?: string
pagingDotsStyle?: CSSProperties
prevButtonClassName?: string
prevButtonStyle?: CSSProperties
prevButtonText?: React.ReactNode
prevButtonOnClick?(event: React.MouseEvent): void
nextButtonOnClick?(event: React.MouseEvent): void
pagingDotsOnClick?(event: React.MouseEvent): void
}
Control Render Functions
The control render functions are render props that let you provide a custom UI that overrides the default UI for each of the control areas. The signature for the render functions is: (props: ControlProps) => JSX.Element
.
interface ControlProps {
currentSlide: number;
slideCount: number;
pagingDotsIndices: number[];
nextDisabled: boolean;
previousDisabled: boolean;
nextSlide(): void;
previousSlide(): void;
goToSlide(targetIndex: number): void;
}
currentSlide
A number
set to the current slide index.
slideCount
A number
set to the number of slides.
pagingDotsIndices
An array number[]
set the indexes of the active slides.
nextDisabled
A boolean
indicating if a custom next slide control be disabled
previousDisabled
A boolean
indicating if a custom next slide control be disabled
nextSlide
A function to invoke to navigate to the next slide.
previousSlide
A function to invoke to navigate to the previous slide.
goToSlide
A function to invoke with a number
parameter to navigate to a specific slide.
Key Code Configuration
A configuration object for the key codes to override the default keyboard keys configured when enableKeyboardControls
is true
. Multiple custom key codes can be provided for each action.
interface KeyCodeConfig {
firstSlide?: number[];
lastSlide?: number[];
nextSlide?: number[];
pause?: number[];
previousSlide?: number[];
}
Easing Functions
(normalizedTime: number) => number
A function accepting a normalized time between 0
and 1
, inclusive, and returning an eased time, which equals 0
at normalizedTime == 0
and equals 1
at normalizedTime == 1
. You can plug in your own custom easing function (e.g., (t) => t
for a linear transition), or import functions from a different library, like d3-ease
.
import { easeCircleOut, easeElasticOut } from 'd3-ease';
// ...
<Carousel easing={easeCircleOut} edgeEasing={easeElasticOut}>
{/* Carousel Content */}
</Carousel>
Please note that using a function for easing
with "In" in it (easeInOut, easeElasticIn, etc.) will make swiping transitions feel a bit clunky, as the velocity at the end of the swipe will suddenly drop to follow the slow startup speed of the "In" easing function. In general, when using custom easing functions, try out both swiping and clicking on the navigation buttons to see how the transitions feel.
