FeatureHub Client SDK

FeatureHub client/browser SDK for feature flags, remote configuration, and A/B testing. This package is designed for browser environments (or any non-Node.js context) and uses Server-Sent Events (SSE) for real-time updates. Version 2.0.2 requires Node >=20.0.0 and is TypeScript-first (ships types). Key differentiators: edge-compatible, supports catch-and-release mode for local feature flag overrides during development, integrates with React SDK via featurehub-react-sdk, and offers a client-side context for multi-environment support. Releases follow a monthly cadence.
