Usage

Start by initializing the featureClient with appKey and envKey which can be found at https://app.featurematrix.io/apps and https://app.featurematrix.io/environments

import { featureClient } from 'featurematrix-react';

featureClient.init({
    appKey: 'ef445c2b-d4b4-43bc-b79a-7956baeef34a',
    envKey: '4306148c-3707-4b2d-99aa-4390f09b4f5a'
});

useFeature hook

useFeature(featureKey: string): boolean

useFeature accepts a feature key as a single argument and returns the state of the feature as a boolean. If the featureClient is not initialized yet or the key is invalid it will return null and will complain in the console.

import { useFeature } from 'featurematrix-react';

export const HomePage = () => {
    const feedbackIsEnabled = useFeature('feedback');

    return (
        <div className="home">
            {feedbackIsEnabled &&
                <Feedback />
            }
        </div>
    );
};

If the feature will be toggled in app dashboard, HomePage component will be rerendered.

withFeatures Higher Order Component

withFeatures<T>(featureKeys: string[], ComponentToWrap: React.ComponentType<T>): React.ComponentType<T & FeatureProps>

withFeatures accepts a list of feature keys as the first argument and the component to be wrapped as the second argument. Returns a new component which has a getFeatureState prop.

getFeatureState(key: string): boolean

If the featureClient is not initialized yet or the key is invalid getFeatureState will return null and will complain in the console.

import { withFeatures } from 'featurematrix-react';

class HomePage extends Component {
    render() {
        const feedbackIsEnabled = props.getFeatureState('feedback');

        return (
            <div className="home">
                {feedbackIsEnabled &&
                    <Feedback />
                }
            </div>
        );
    }
}

export default withFeatures(['feedback'], HomePage);
// or with react-redux connect
export default connect(mapStateToProps, mapDispatchToProps)(withFeatures(['feedback'], HomePage));

If the feature will be toggled in app dashboard, HomePage component will be rerendered.
