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

@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:

• GO
• Javascript (Node)
• Javascript (Web)
• Python
• React
• Swift
