react-native-masonry

🙌 A easy to use react-native component to render a masonry~ish layout for local and remote images with support for dynamic column rendering, progressive image loading, device rotation, on-press handlers, and headers/captions.

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
     bricks=[
       { uri: 'http://image1.jpg' },
       { uri: 'http://image2.jpg' },
       { uri: 'http://image3.jpg' }
     ]
   />

4. 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

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:

brick.uri | Required

Type: String

The uri of the image location.

IE: uri: 'http://cats.com/cat1.jpeg'

brick.onPress

Type: 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>.

IE: onPress: (data) => goTo(data.id)

brick.renderHeader

Type: Func (brick.data) -> React Component

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.

IE: Brick with renderHeader

{
  // 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>
    );
  }
}

brick.renderFooter

Type: Func (brick.data) -> React Component

A function that is executed BELOW the brick image renderFooter() is passed brick.data to allow dynamic content rendering of components.

IE: Brick with renderFooter

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