OpenFeature JavaScript SDKs

👋 Hey there! Thanks for checking out the OpenFeature JavaScript SDKs

What is OpenFeature?

OpenFeature is an open standard that provides a vendor-agnostic, community-driven API for feature flagging that works with your favorite feature flag management tool.

Why standardize feature flags?

Standardizing feature flags unifies tools and vendors behind a common interface which avoids vendor lock-in at the code level. Additionally, it offers a framework for building extensions and integrations and allows providers to focus on their unique value proposition.

🔧 Components

This repository contains both the server-side JS and web-browser SDKs. For details, including API documentation, see the respective README files.

Server SDK, for use in Node.js and similar runtimes.
- NestJS SDK, a distribution of the Server SDK with built-in NestJS-specific features.
Web SDK, for use in the web browser.
- React SDK, a distribution of the Web SDK with built-in React-specific features.

Each have slightly different APIs, but share many underlying types and components.
