react-native-opengraph-kit

A set of components and utils useful to extract opengraph data directly from your react-native app, with almost no dependency.

For react-native v0.44+

:warning: 2.0.0 is a breaking change, the Parser is now returning an Array of results for all the URLs in the text analysed.

If you are using only the OpenGraphAwareInput, you don't have to change anything.

Subcomponents

import { OpenGraphAwareInput, OpenGraphDisplay, OpenGraphParser } from 'react-native-opengraph-kit';

OpenGraphAwareInput

<OpenGraphAwareInput
    containerStyle={styles.textInputContainer}
    textInputStyle={styles.textInput}
    onChange={this.doWhatIWantWithTheContent}
/>

Property Name | Type | Description --- | --- | --- containerStyle | ViewPropTypes.style | A style to pass to customize the style of the container onChange | React.PropTypes.func | The function to call on change in the TextInput textInputStyle | TextInput.propTypes.style | A style to pass to customize the style of the textInput onIconPress | React.PropTypes.func | A function to call when the Icon is pressed (see OpenGraphDisplay). By default, the function clear the opengraphdata field returned (and therefore the resulting OpenGraphDisplay). iconSource | Image.propTypes.source | The Image Source to use as Icon (see OpenGraphDisplay) iconStyle | Image.propTypes.style | The style of the Icon (see OpenGraphDisplay) showIcon | React.PropTypes.bool | Should we show the Icon or not? (default is false) resultLimit | React.PropTypes.number | Max number of parsed OpenGraph links to display (default is 1)

OpenGraphDisplay

Fully customizable widget for the extracted data

<OpenGraphDisplay
    data={this.state.dataIGotFromTheParser}
/>

Property Name | Type | Description --- | --- | --- data | React.PropTypes.shape({ url: React.PropTypes.string, image: React.PropTypes.string, title: React.PropTypes.string, description: React.PropTypes.string,}).isRequired | The data gotten out of the OpenGraphAwareInput or the OpenGraphParser containerStyle | ViewPropTypes.style | A style to pass to customize the style of the container imageStyle | Image.propTypes.style | A style to pass to customize the style of the image textContainerStyle | ViewPropTypes.style | A style to pass to customize the style of the textContainer touchContainerStyle | ViewPropTypes.style | A style to pass to customize the style of the View that is touchable when the content is "rich" (as opposed to urlOnlyTouchContainerStyle) titleStyle | Text.propTypes.style | A style to pass to customize the style of the title descriptionStyle | Text.propTypes.style | A style to pass to customize the style of the description urlStyle | Text.propTypes.style | A style to pass to customize the style of the url urlOnlyTouchContainerStyle | ViewPropTypes.style | A style to pass to customize the style of the View that is touchable when the content is "poor" (Just the url, no info has been successfully fetched) onIconPress | React.PropTypes.func | When this function is provided, puts an Icon on the right of the OpenGraphDisplay (by default an x) iconSource | Image.propTypes.source | The Image Source to use as Icon iconStyle | Image.propTypes.style | The style of the Icon

OpenGraphParser

Where the magic happens

handleTextChange = (event) => {
    OpenGraphParser.extractMeta(event.nativeEvent.text)
    .then((data) => {
        this.setState({ data });
    })
    .catch((error) => {
        console.log(error);
    });
}

render() {
    return (
        <TextInput
            onChange={this.handleTextChange}
        />
    );
}

Example of data object:

[
    {
        description: "We're a young and inspired team that leverages technical knowledge to turn ideas into creative and efficient digital solutions.",
        image: "https://osedea.com/images/thumbnail-osedea-1.png",
        title: "OSEDEA | Digital Efficiency & Creativity",
        type: "website",
        url: "http://osedea.com",
    }
