一个3DCarousel组件，用于使用React构建的图像，并利用react-spring来控制幻灯片过渡_TypeSc.zip

[](https://gist.github.com/cheerfulstoic/d107229326a01ff0f333a1d3476e068d) # react-spring-3d-carousel A 3D Carousel component for images built with [React](https://reactjs.org/) and utilizing [react-spring](https://github.com/react-spring/react-spring) for controlling slide transitions. It's primarily meant to be controlled via the goToSlide prop but I also provided a showNavigation prop if you don't feel like making your own navigation. This should go without saying, but if you use this component make sure to test it for performance and compatability with your target browsers. ## Example [](https://codesandbox.io/s/1v96j74484?view=preview) ## Installation and usage Install it via npm: ``` npm i react-spring-3d-carousel ``` or yarn: ``` yarn add react-spring-3d-carousel ``` Then import the Carousel component like so : ``` import Carousel from 'react-spring-3d-carousel'; ``` The only thing this component needs to run is an array of slides, which are objects with a unique key property and a content property containing an image instance : ``` const slides = [ { key: uuidv4(), content: <img src="https://picsum.photos/800/800/?random" alt="1" /> }, { key: uuidv4(), content: <img src="https://picsum.photos/800/800/?random" alt="2" /> }, { key: uuidv4(), content: <img src="https://picsum.photos/600/800/?random" alt="3" /> }, { key: uuidv4(), content: <img src="https://picsum.photos/800/500/?random" alt="4" /> }, { key: uuidv4(), content: <img src="https://picsum.photos/800/800/?random" alt="5" /> }, { key: uuidv4(), content: <img src="https://picsum.photos/500/800/?random" alt="6" /> }, { key: uuidv4(), content: <img src="https://picsum.photos/800/600/?random" alt="7" /> }, { key: uuidv4(), content: <img src="https://picsum.photos/800/800/?random" alt="8" /> } ]; ... <Carousel slides={slides} /> ``` And you're all set. You can also use props for better control of how the carousel looks and behaves: ## Props | Name | Default value | Description | | --------------- | -------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | slides | --- | An array containing elements of the form `{ key, content, onClick? }` where key holds any unique value and content holds a reference to a JSX `<img />` to be displayed. onClick is an optional property that may be used to pass a callback method which will be invoked when the slide is clicked. | | goToSlide | `null` | Setting this prop will cause the carousel to animate towards the provided index in the slides array. If `showNavigation` is set to false this prop is how you're expected to control the carousel. | | goToSlideDelay | `200` | The amount of milliseconds to delay each slide before moving to the next one while animating towards the index provided in `goToSlide`. | | offsetRadius | `2` | Number of carousel elements to display to the sides of the current slide, this value is clamped between `1` and `Math.floor(slides.length/2)`, and defaults to 2 when it's possible (if there are enough slide elements). | | animationConfig | `{ tension: 120, friction: 14 }` | A config object passed to the slides' Spring element to control the nature of their animation, for more information check the [react-spring docs](http://react-spring.surge.sh/#/api#configs). | | offsetFn | `undefined` | An optional callback function invoked with `(offsetFromRadius: number, index: number)` by each slide per animation to override its style in relation to its current offset (negative numbers are to the left of the center, positive are to the right, with 0 being the center) and index. Should return an object `{ transform?: string; left?: string \| number; opacity?: number }`. Any missing key within the object would trigger the default style behaviours. e.g. `(offsetFromCenter) => ({ opacity: 1 - Math.abs(offsetFromCenter) / 10 })` would change the way the opacity is rendered but not affect `transform` or `left`.
