react-native-masonry

🙌 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 🍰:

Dynamic Column Rendering
Progressive Item Loading
Device Rotation
On-press Handlers
Custom Headers & Captions
Optimized to Rendering Large List
Support for Third-Party Image components
Automatic Sizing Based on Available Space

Usage

Install the repository

$ npm install --save react-native-masonry

Add an import to the top of your file

import Masonry from 'react-native-masonry';

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' }
  ]}
/>

Still a bit confused 😖, 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

Props	Type	Description	Default
bricks	array	A 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'}]`	[]
columns	num	Desired number of columns	2
sorted	bool	Whether to sort `bricks` according to their index position or allow bricks to fill in as soon as the `uri` is ready.	false
imageContainerStyle	object	The styles object which is added to the Image component	{}
customImageComponent	`React.Component`	Use 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
customImageProps	object	Pass along additional properties to a `props.customImageComponent`.	n/a
spacing	num	Gutter size of the column. The spacing is a multiplier of 1% of the available view.	1
refreshControl	`React.Component`	A component to be used as a refresh element for the Masonry component	n/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.

Property	Type	Required	Description	Example
uri	`string`	✅	The uri of the image location.	http://test.com/i.jpeg
key	`string`	🚫	Optional 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
onPress	`func (brick.data)`	🚫	A 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)`
renderHeader	`func (brick.data)`	🚫	A 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
renderFooter	`func (brick.data)`	🚫	A function that is executed BELOW the brick image `renderFooter()` is passed `brick.data` to allow dynamic content rendering of components.	Figure 2

Usage Examples

ℹ️ 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>
    );
  }
}

ℹ️ 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>
    );
  }
}

ℹ️ 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} />
