ReactSiema - Lightweight and simple carousel for React

ReactSiema is a lightweight carousel plugin for React. It's a wrapper based on decent library Siema.

Demo

• ReactSiema

Download on npm

• ReactSiema package on npm

Setup

npm install react-siema --save

import ReactSiema from 'react-siema'

const Slide = (props) => <img {...props} alt="slide" />

const App = () => <ReactSiema>
    <Slide src="#" />
    <Slide src="#" />
    <Slide src="#" />
</ReactSiema>

If you want to run a demo:

• Clone the repo
• run npm install
• run npm start, which will setup a development server with sample gallery

Options

Component comes with some default settings, that can be adjusted via props.

resizeDebounce: 250
duration: 200
easing: 'ease-out'
perPage: 1
startIndex: 0
draggable: true
threshold: 20
loop: false

Example of passing custom options:

const Slide = (props) => <img {...props} alt="slide" />

const options = {
    duration: 500,
    loop: true
}

const App = () => <ReactSiema {...options}>
    <Slide src="#" />
    <Slide src="#" />
    <Slide src="#" />
</ReactSiema>

API

Most of the API comes from Siema library mentioned above.

• next() - go to next slide
• prev() - go to previous slide
• goTo(index) - go to a specific slide
• currentSlide - index of the current active slide (read only)

Example of API usage

API is accessible via refs.

const Slide = (props) => <img {...props} alt="slide" />

const App = () => {
    let slider
    
    return (
        <div>
            <ReactSiema ref={siema => slider = siema}>
                <Slide src="#" />
                <Slide src="#" />
                <Slide src="#" />
            </ReactSiema>
            <button onClick={() => slider.prev()}>prev</button>
            <button onClick={() => slider.next()}>next</button>
        </div>
    )
}

Click Events

This version of react-siema has been extended to include the ability to attach very simple click events to items passed into the slider. It will only fire the click event if the slide wasn't dragged.

Provide a normal event handler method the onClick prop in <ReactSiema>. Current slide information can be retrieved from the instance of siema. (this.slider.currentSlide below).

const Slide = (props) => <img {...props} alt="slide" />

class App extends Component {
    constructor() {
        this.slider = null;
    }

    handleClick = (e) => {
        console.log(`Index of the clicked slide is ${this.slider.currentSlide}`);
    }
    
    render() {
        return (
            <div>
                <ReactSiema ref={siema => this.slider = siema} onClick={this.handleClick}>
                    <Slide src="#" />
                    <Slide src="#" />
                    <Slide src="#" />
                </ReactSiema>
                <button onClick={() => slider.prev()}>prev</button>
                <button onClick={() => slider.next()}>next</button>
            </div>
        )
    }
}
