How to use:

In order for the component's styling to work, you need to import style.css:

import `../node_modules/react-hovering-cards-carousel/dist/style.css`

<Carousel/>:

<Carousel cards={events} scale={1.25} buttonsBackground={"red"} reloadOnResize={false}/>

• cards props is an array of type Custom, Article or Event where the items are the ones getting rendered.
• scale (default: 1) prop accepts a number which signifies the times the component sizes up or down depending on your needs.
• reloadOnResize (default: true) prop accepts a boolean value which would either enable or disable the window reloading behavior triggered by the component when resolution is being changed.
• upcomingEventLabel (optional) prop accepts an object defining a specific label which is shown when an event is upcoming. More about this in the Quirks section.
• buttonColor (default: black) set color of arrow buttons.
• buttonSpacing (default: 40) control the space between the buttons and the main container. Value is in pixels and multiplied by -1. Hence values lower than > 40 bring the buttons closer to the container.

type Custom:

image: string; // <img src={prop.image}>
children: JSX.Element; // this is what gets rendered when you hover over the card

How to create a JSX Element:

type CustomChildProp = {
  title: string;
  description: string;
  // add additional
};

let CustomChild = (prop: CustomChildProp) => {
  return (
    <div>
      <h1>{prop.title}</h1>
      <p>{prop.description}</p>
      {/* add additional */}
    </div>
  );
};

Additionally you may (preferably) add specific styling to your JSX Element:

import './style.css' // either in a parent component or in the same place
// where you define the CustomChild Element


let CustomChild = (prop: CustomChildProp) => {
  return (
    <div className="container">
      <h1 className="title-header">{prop.title}</h1>
      <p className="description">{prop.description}</p>
      {/* add additional */}
    </div>
  );
};

Create a <Carousel/> using type Custom (see example code here):

import {Custom} from 'react-hovering-cards-carousel'

.
.
.

// declare array
const arr = [
  new Custom("https://example.com", <CustomChild title="Example", description="This is an example"/>),

  new Custom("https://secondexample.uk", <CustomChild title="Example Two", description="This is the second example">)
]

.
.
.

<Carousel cards={arr}/>

The types below were developed for internal use within the @AUBGTheHub organization, but you can make use of them as you wish!

type Event:

title: string;
image: string; // <img src={prop.image}/>
description: string;
location: string; // url (e.g. Google Maps)
startingTime: string; // ISO String
link: string; // url (e.g. Facebook)

type Article:

title: string;
link: string; // url (e.g. Medium)
author: string;
image: string; // <img src={prop.image}/>

---

Initialize the component:

Create a list and populate it with objects of type Custom | Event | Article and then pass it to <Carousel/>

• hardcoded items

import "../node_modules/react-hovering-cards-carousel/dist/style.css"
import { Carousel, Custom } from "react-hovering-cards-carousel";

.
.
.

let customArr: Array<Custom> = [
    new Custom("first item", ...),
    new Custom("second item", ...),
    ...
]

return (
    <div className="container">
        <Carousel cards={customArr}/>
    </div>
)

• fetch items with an api request and map them (an example with type Event):

 const [events, setEvents] = useState<Event[]>([]);

  useEffect(() => {
    axios({
      method: "get",
      url: "https://dev.thehub-aubg.com/api/event",
    }).then((res) => {
      let resData: Array<unknown> = res.data.data.events;
      let temp: Array<Event> = [];

      if (resData) {
        resdata.forEach((element: any) => {
          temp.push(
            new Event(
              element.title,
              element.banner,
              element.description,
              element.locationlink,
              element.startdate,
              element.facebooklink
            )
          );
        });

      setEvents(temp);
      }
    });
  }, []);


    return (
    <div className="App">
      <Carousel cards={events} />
    </div>
  );

<Carousel/> styling:

You may use hex, rgb() and rgba() values everywhere color is mentioned.

<Carousel cards={cards} buttonColor={"red"}>
// you can define colors the same way you do in css (hex, rgb(), rgba())

Quirks:

Events - You may add labels for upcoming events:

upcomingEventLabel is an object which requires text, backgroundColor and color.

• text is what's getting rendered in the div
• backgroundColor is the color of the box
• color is the color of the text

<Carousel
  cards={events}
  upcomingEventLabel={{
    text: "Upcoming",
    backgroundColor: "rgba(255, 255, 255, 0.7)",
    color: "black",
  }}
/>

Box won't get rendered if prop.startingTime cannot be parse as a Date() object.
