Installation

Install the module using:

npm install --save featuretoggle-react

or:

yarn add featuretoggle-react

Usage

import the required dependencies:

``js
import {
FeatureToggleWrapper,
flagsmithClient,
optimizelyClient, // or alternatively
launchdarklyClient, // or alternatively
FeatureToggle,
On,
Off,
} from "featuretoggle-react";
`

Initialize one of the Clients provided: flagsmithClient, optimizelyClient or launchdarklyClient:

`js
const provider = flagsmithClient({
environmentID: "xxxxxxxxxxxxxxxxxxxxx"
});
`

or:

`js
const provider = optimizelyClient({
audience: 'xxxxxxxxxxxx',
sdkKey: 'xxxxxxxxxxxxxxx',
});
`

or:

`js
const provider = launchdarklyClient({
clientSideId: 'xxxxxxxxxxxxxxxx',
user: {
key: 'xxxxxxxxx',
},
});

`
Use the FeatureToggle:

`js
export default function App() {
return (





);
}
`
The featuretoggle-react module will fetch the toggle state from the relevant service provider and display the toggled state according to the received data.

You can also create your own provider along those lines:

`js
const provider = {
init: (handler) => {
const featureToggles = {};
// call your endpoint or insert mock values into featureToggles here
handler(featureToggles);
}
};
`
Warning: reloads and updates are not handled in this version. This is planned for version 2.x. Currently, the feature toggles are fetched and updated only once, when the first ` element is rendered.
