Introduction:

A React.js Masonry component. (Also available as a mixin if needed)

Live demo:

hearsay.me

Usage:

The component is bundled with Masonry, so no additional dependencies needed!
You can optionally include Masonry as a script tag if there should be any reason for doing so <script src='//cdnjs.cloudflare.com/ajax/libs/masonry/3.1.5/masonry.pkgd.min.js' />
To use the component just require the module.

Basic usage

npm install --save react-masonry-component

import * as React from 'react';
import Masonry from 'react-masonry-component';

const masonryOptions = {
    transitionDuration: 0
};

const imagesLoadedOptions = { background: '.my-bg-image-el' }

class Gallery extends React.Component {
    render() {
        const childElements = this.props.elements.map(function(element){
           return (
                <li className="image-element-class">
                    <img src={element.src} />
                </li>
            );
        });
    
        return (
            <Masonry
                className={'my-gallery-class'} // default ''
                elementType={'ul'} // default 'div'
                options={masonryOptions} // default {}
                disableImagesLoaded={false} // default false
                updateOnEachImageLoad={false} // default false and works only if disableImagesLoaded is false
                imagesLoadedOptions={imagesLoadedOptions} // default {}
            >
                {childElements}
            </Masonry>
        );
    }
}

export default Gallery;

ES6-style modules are also supported, just use:

import Masonry from 'react-masonry-component';

Custom props

You can also include your own custom props - EG: inline-style and event handlers.

import * as React from 'react';
import Masonry from 'react-masonry-component';

const masonryOptions = {
    transitionDuration: 0
};

const style = {
    backgroundColor: 'tomato'
};

class Gallery extends React.Component {
    handleClick() {}
    render() {
        return (
            <Masonry
                className={'my-gallery-class'}
                style={style}
                onClick={this.handleClick}
            >
                {...}
            </Masonry>
        );
    }
}

export default Gallery;

Accessing Masonry instance

Should you need to access the instance of Masonry (for example to listen to masonry events) you can do so by using refs.

import * as React from 'react';
import Masonry from 'react-masonry-component';

class Gallery extends React.Component {
    handleLayoutComplete() { },

    componentDidMount() {
        this.masonry.on('layoutComplete', this.handleLayoutComplete);
    },

    componentWillUnmount() {
        this.masonry.off('layoutComplete', this.handleLayoutComplete);
    },

     render() {
         return (
             <Masonry
                 ref={function(c) {this.masonry = this.masonry || c.masonry;}.bind(this)}
             >
                 {...}
             </Masonry>
         );
     }
}

export default Gallery;

Images Loaded Options

React Masonry Component uses Desandro's imagesloaded library to detect when images have loaded. Should you want to pass options down to it then you need to populate the imagesLoadedOptions property on React Masonry Component.

This will most commonly be used when the elements in your gallery have CSS background images and you want to capture their load event. More info availabe on the imagesloaded website.

eg:

import * as React from 'react';
import Masonry from 'react-masonry-component';

class Gallery extends React.Component {
  render() {
    const imagesLoadedOptions = { background: '.my-bg-image-el' }
    
    return (
        <Masonry
            className={'my-gallery-class'}
            elementType={'ul'}
            options={masonryOptions}
            imagesLoadedOptions={imagesLoadedOptions}
        >
            <div className="my-bg-image-el"></div>
        </Masonry>
    );
  }
}

export default Gallery;

Events

onImagesLoaded - triggered when all images are loaded or after each image is loaded when updateOnEachImageLoad is set to true
onLayoutComplete - triggered after a layout and all positioning transitions have completed.
onRemoveComplete - triggered after an item element has been removed

class Gallery extends React.Component {
    componentDidMount() {
        this.hide();
    },
    handleImagesLoaded(imagesLoadedInstance) {
        this.show();
    },
    render() {
        return (
            <Masonry
                onImagesLoaded={this.handleImagesLoaded}
                onLayoutComplete={laidOutItems => this.handleLayoutComplete(laidOutItems)}
                onRemoveComplete={removedItems => this.handleRemoveComplete(removedItems)}
            >
                {...}
            </Masonry>
        )
    }
}
