React Native auto height image

react-native-auto-height-image

This component provides you a simple way to load a remote image and automatically set Image height to the image dimension which fits the provided width.

ReactNative Image component needs users to set both width and height props.

Installation

yarn add react-native-auto-height-image

npm install react-native-auto-height-image

Usage

Use local or remote files:

import React, { Component } from 'react';
import AutoHeightImage from 'react-native-auto-height-image';

import image from 'gallifrey-falls.png';

export default class Demo extends Component {
    render() {
        return (
            <View>

                <AutoHeightImage
                    width={100}
                    source={image}
                />

                <AutoHeightImage
                    width={100}
                    source={{uri: 'http://placehold.it/350x150'}}
                />

            </View>
        );
    }
}

You can even specify fallback images for when the source fails to load:

import React, { Component } from 'react';
import AutoHeightImage from 'react-native-auto-height-image';

import image from 'gallifrey-falls.png';

export default class Demo extends Component {
    render() {
        return (
            <AutoHeightImage
                width={100}
                source={{uri: 'https://vivaxy.github.io/404'}}
                fallbackSource={image}
            />
        );
    }
}
