``sh npm i -s react-glider`

`$3`

`import * as React from 'react';

To use the CSS for Glider.js, you may import it from the npm module:

`js import "glider-js/glider.min.css";`

or reference the CSS file in your (not recommended):

`html rel="stylesheet" href="https://unpkg.com/glider-js@1.7.7/glider.min.css" />`

#### Demo Defaults

This package also exposes the CSS used to render the demo which may also be imported as follows.

Note that this file is no longer maintained.

`js import Glider from "react-glider/glider.defaults.css";`

`$3`

| Option | Description | | ---------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | hasArrows | Show/hide arrows. (default = false) | | hasDots | Show/hide dots. (default = false) | | iconLeft | ReactNode for the left arrow. (default = '«') | | iconRight | ReactNode for the right arrow. (default = '»') | | scrollToSlide | Starting slide (default = 0) | | scrollToPage | Starting page (default = 0) | | slidesToShow | The number of slides to show in container. If this value is set to auto, it will be automatically calculated based upon the number of items able to fit within the container viewport. This requires setting the itemWidth option. | | slidesToScroll | The number of slides to scroll when arrow navigation is used. If this value is set to auto, it will match the value of slidesToScroll. | | itemWidth | This value is ignored unless slidesToShow is set to auto, in which it is then required. | | exactWidth | This prevents resizing items to fit when slidesToShow is set to auto. | | resizeLock | If true, Glider.js will lock to the nearest slide on resizing of the window | | rewind | If true, Glider.js will scroll to the beginning/end when its respective endpoint is reached | | duration | An aggravator used to control animation speed. Higher is slower. (default = 0.5) | | dots | A string containing the dot container selector | | arrows | An object containing the prev/next arrows selectors | | draggable | If true, the list can be scrolled by click and dragging with the mouse. (default = false) | | dragVelocity | How much to aggravate the velocity of the mouse dragging. (default = 3.3) | | scrollPropagate | Whether or not to release the scroll events from the container. (default = true) | | propagateEvent | Whether or not Glider.js events should bubble (useful for binding events to all carousels). (default = false) | | scrollLock | If true, Glider.js will scroll to the nearest slide after any scroll interactions. (default = false) | | skipTrack | Whether or not Glider.js should skip wrapping its children with a 'glider-track'

. NOTE: If true, Glider.js will assume that the 'glider-track' element has been added manually. All slides must be children of the track element. (default = false) |
| scrollLockDelay  | How long (ms) to wait after scroll event before locking, if too low, it might interrupt normal scrolling. (default = 250)                                                                                                                                   |
| responsive       | An object containing custom settings per provided breakpoint. Glider.js breakpoints are mobile-first, be conscious of your ordering. Supported responsive settings are

slidesToShow, slidesToScroll, itemWidth, and duration

.                       |
| containerElement | Replace container HTML element.                                                                                                                                                                                                                             |
| easing           | Use any custom easing function, compatible with most easing plugins.                                                                                                                                                                                        |

If the Glider component should display arrows, you can configure these using the arrows prop.

#### Selectors

The arrows prop supports an object containing left and right CSS selectors.

`jsx arrows={{ prev: '#buttonPrev', next: '#buttonNext', }}`

_Note that if you have multiple Glider elements on the same page, you need to assign a different CSS selector to each Glider._

#### Elements

The arrows prop supports an object containing left and right references to an HTML element.

When using native HTML elements:

`jsx arrows={{ prev: document.getElementById("prev"), next: document.getElementById("next") }}`

When using useRef:

`jsx arrows={{ prev: leftArrowEl.current, next: rightArrowEl.current, }}`

_Note that useRef will assign a value to current after the component has rendered. This means that on the first render, current is null._

`$3`

You can set different settings for different viewport widths.

`jsx slidesToShow={1} scrollLock responsive={[ { breakpoint: 864, settings: { slidesToShow: 3, }, }, ]} > { ... }`

_Note that React Glider is designed to be mobile-first, so the order of your breakpoints should be small-to-large._

`$3`

If you would like to use a custom element or React component as the parent for your slides, you can use the containerElement property.

`jsx function ContainerElement({ children }) { return

{children}

;
}

function MyComponent() { return slidesToShow={1} containerElement={ContainerElement} > { ... } }`

`$3`

| Event | Description | | -------------- | ----------------------------------------------------------------------------- | | onLoad | Called after Glider component is initialized. | | onAnimated | Called whenever a Glider.js paging animation is complete | | onRemove | Called whenever a Glider.js animation is complete | | onSlideVisible | Called whenever a slide a shown. Passed an object containing the slide index | | onRefresh | Called whenever Glider.js refreshes it's elements or settings | | onAdd | Called whenever an item is added to Glider.js | | onDestroy | Called whenever a Glider.js is destroyed | | onSlideHidden | Called whenever a slide a hidden. Passed an object containing the slide index |

`$3`

To get access to the current glider instance this react component exposes a ref.

`tsx function Example() { const gliderRef = useRef(null); return (


              type="button"
        onClick={() => {
          const random = Math.floor(Math.random() * 12);
          gliderRef.current?.scrollItem(random);
        }}
      >
        Scroll to random item
      
              className="glider-container"
        draggable
        hasDots
        slidesToShow={1}
        scrollLock
        ref={gliderRef}
      >
        
          1


  );
}

The CSS for the perspective view is not included in Glider.js or this package. You can find it in perspective.css. Please do not file bugs for it as I do not want to support it.

`FAQs`

If you are interested in migrating from react-slick, please note that react-glider only includes a subset of the features available in react-slick. Most notably, react-glider doesn't include variable width or custom transitions, while autoplay must be handled by you. If you are using react-slick as a carousel to list elements, react-slick probably includes more features than you need. In such cases, replacing it with react-glider would reduce the JavaScript KBs while providing your users with a jank-free experience.

import/no-extraneous-dependencies requires that all dependencies are included in the project's package.json file. Since the CSS file is generated by glider-js, it will not be listed in your package.json file. The preferred option would be to create a local CSS file containing the glider.css file's contents. Alternatively, you may disable the eslint warning for that line. We do not recommend installing glider-js as a dependency in your package as you would then be responsible for maintaining the glider-js and react-glider dependencies in your project.

`$3`

You may customize the dots by overriding the CSS for .glider-dots and glider-dot.

Alternatively, you may pass a CSS selector to the dots property to assign a DOM element as the container for the Glider's pagination. This allows you to override the CSS for .glider-dots using CSS specificity.

`.my-dots-container.glider-dots { / ... / }`

This is also possible when using CSS modules and allows you to have multiple Glider components on the same page, each with different styles.

`jsx


      dots={

.${style.dots}

}
    slidesToShow={1}
  >
    { ... }

The recommended approach for lazy loading images is to use the browser's loading="lazy" implementation. You can use the slide's index to know which images should have the attribute set.

`$3`

As react-glider is a wrapper for Glider.js, it should run on all modern browsers. Support for older browsers can be achieved by polyfilling document.classList, window.requestAnimationFrame, Object.assign and CustomEvent.
