@featureflip/openfeature-node

OpenFeature provider for Featureflip, backed by the @featureflip/node server SDK.

Installation

npm install @openfeature/server-sdk @featureflip/node @featureflip/openfeature-node

@openfeature/server-sdk and @featureflip/node are peer dependencies — your application installs and owns a single copy of each, so the provider shares one underlying Featureflip client core with any direct SDK usage.

Usage

import { OpenFeature } from '@openfeature/server-sdk';
import { FeatureflipProvider } from '@featureflip/openfeature-node';

await OpenFeature.setProviderAndWait(
  new FeatureflipProvider({ sdkKey: 'your-server-sdk-key' }),
);

const client = OpenFeature.getClient();
const enabled = await client.getBooleanValue('my-flag', false, {
  targetingKey: 'user-42',
});

The constructor accepts either a Featureflip config object or an existing FeatureflipClient instance.

• targetingKey maps to Featureflip's user_id
• Matched variation keys surface as variant; ruleId / prerequisiteKey surface in flagMetadata
• OpenFeature track() calls forward to Featureflip custom events
