Hyphen has built out SDK's for go, python, react, nodejs, javascript, and swift either via our native support or via Open Feature.

Native SDK's

@hyphen/sdk

Server-side Node.js SDK for feature flag evaluation and management. Ideal for backend services, APIs, and server-rendered applications.

Simple use case:

import { HyphenClient } from '@hyphen/sdk';

const client = new HyphenClient({ apiKey: 'your-api-key' });
await client.initialize();

const isEnabled = await client.isEnabled('new-feature', { userId: '123' });
if (isEnabled) {
  // Execute new feature code
}

@hyphen/browser-sdk

Client-side JavaScript SDK for web browsers. Optimized for client-side feature flag evaluation with minimal bundle size.

Simple use case:

import { HyphenBrowserClient } from '@hyphen/browser-sdk';

const client = new HyphenBrowserClient({ apiKey: 'your-client-key' });
await client.initialize();

const showNewUI = await client.isEnabled('new-ui-design', {
  userId: user.id
});

@hyphen/react-sdk

React-specific SDK with hooks and components for seamless feature flag integration in React applications.

Simple use case:

import { HyphenProvider, useFeatureFlag } from '@hyphen/react-sdk';

function App() {
  return (
    <HyphenProvider apiKey="your-client-key">
      <MyComponent />
    </HyphenProvider>
  );
}

function MyComponent() {
  const isEnabled = useFeatureFlag('new-feature');

  return isEnabled ? <NewFeature /> : <OldFeature />;
}

We are currently planning to support native sdk's for python, go, .net, and java in the near future.

Open Feature SDK's

OpenFeature is an open standard that provides a vendor-agnostic, unified API for feature flagging. Hyphen supports OpenFeature through providers for multiple languages and frameworks.

Hyphen has made the following open feature providers for you to use:
