VWO Feature Management and Experimentation SDK

The VWO Feature Management and Experimentation SDK (vwo-fme-node-sdk) provides robust capabilities for integrating feature flagging and experimentation directly into Node.js and browser-based JavaScript applications. Currently stable at version 1.41.0, the library receives consistent updates, indicated by frequent minor and patch releases. It allows developers to dynamically manage feature rollouts, conduct A/B tests, and track user interaction events within the VWO platform. Key features include the ability to specify custom bucketing seeds for consistent user group assignments (v1.41.0), automatic session management (v1.37.0) to link server-side decisions with client-side experiences, and a flexible `Connector` API (v1.35.0) for custom persistent storage of VWO settings. Notably, a significant architectural change in v1.36.0 shifted the SDK from a singleton model to supporting multiple isolated instances, enhancing flexibility for complex application architectures.
