:raised_hands: An easy to use, pure JS react-native component to render a masonry~ish layout for remote images

react-native-masonry is built with the following features and functionalities baked in 🍰:

v0.1.0 Demo

Usage

  1. Install the repository
    $ npm install --save react-native-masonry
    
  2. Add an import to the top of your file
    import Masonry from 'react-native-masonry';
    
  3. At a minimal, declare the component in the render method prividing data for bricks
    <Masonry
      sorted // optional - Default: false
      columns={4} // optional - Default: 2
      bricks={[
        { uri: 'http://image1.jpg' },
        { uri: 'http://image2.jpg' },
        { uri: 'http://image3.jpg' }
      ]}
    />
    
  4. Still a bit confused :confounded:, or want to see it in action? No worries, run the example application on your local machine to examine how to get started or try it out on Expo.io.

Component Props

PropsTypeDescriptionDefault
bricksarrayA list of Object:Bricks to be passed into the row renderer. I.E:,bricks=[{id: 1, uri: 'https://image.jpg', onPress: (brick) => this.redirect(brick.id)}, {id: 2, uri: 'https://hyper.jpg'}][]
columnsnumDesired number of columns2
sortedboolWhether to sort bricks according to their index position or allow bricks to fill in as soon as the uri is ready.false
imageContainerStyleobjectThe styles object which is added to the Image component{}
customImageComponentReact.ComponentUse a custom component to be rendered for the Image. This will work properly, as long as the component follows the standard interface of the react-native image component.n/a
customImagePropsobjectPass along additional properties to a props.customImageComponent.n/a
spacingnumGutter size of the column. The spacing is a multiplier of 1% of the available view.1
refreshControlReact.ComponentA component to be used as a refresh element for the Masonry componentn/a

Brick Properties

"Bricks" are the basic building block of the masonry and are passed into the props.bricks. They essentially represent the items within each column and require a uri property at a minimum. However, you can freely add additional properties to the data property if you need access to certain data within your brick.onPress handler and footer/header renderer. The following properties are available.

PropertyTypeRequiredDescriptionExample
uristring✅The uri of the image location.http://test.com/i.jpeg
keystringđŸšĢOptional item key. By default, uri is used as the key for each item. It's recommended to set a unique key here, but it is not required. The key is required if you need to have image with the same uri more than once in your list.image01
onPressfunc (brick.data)đŸšĢA function handler when the brick is pressed. The function will be called with the instance of the brick, which provides it's dimensions, columns, as well as any user defined properties passed into the bricks prop. An image will be wrapped by a TouchableHighlight.onPress: (data) => goTo(data.id)
renderHeaderfunc (brick.data)đŸšĢA function that is executed ABOVE the brick image, this function must return a React Component. renderHeader() is passed brick.data to allow dynamic content rendering of components.Figure 1
renderFooterfunc (brick.data)đŸšĢA function that is executed BELOW the brick image renderFooter() is passed brick.data to allow dynamic content rendering of components.Figure 2

Usage Examples

ℹī¸ Figure 1: Brick with renderHeader

Accomplishing a top bar indicating the user's avatar and name

{
  // User defined data
  data: {
    user: {
        name: 'Henry',
        profilePic: 'https://user.jpeg'
    }
  }
  uri: 'https://example.com/mainImage.jpeg',
  renderHeader: (data) => {
    return (
      <View>
          <Image source={{ uri: data.user.profilePic }} style={{ width: 50, height: 50}}>
          <Text>{data.user.name}</Text>
      </View>
    );
  }
}

ℹī¸ Figure 2: Brick with .renderFooter

Creating a bottom bar to include additional metadata

{
  data: {
    caption: 'Summer Recipies'
  },
  uri: 'https://example.com/mainImage.jpeg',
  renderFooter: (data) => {
    return (
        <View>
            <Text>{data.caption}</Text>
        </View>
    );
  }
}

ℹī¸ Figure 3: Using Third-Party Image Components

How to leverage third-party components like <FastImage> and apply unique properties across all images

import FastImage from 'react-native-fast-image';

const fastProps = {
    onProgress: { e => console.log(e.nativeEvent.loaded / e.nativeEvent.total) },
    resizeMode: FastImage.resizeMode.contain
};

// ... Where Masonry is called
<Masonry
    bricks={data}
    customImageComponent={FastImage}
    customImageProps={fastProps} />
