LaunchDarkly has introduced two new SDKs - a client-side SDK for Node.js and a server-side SDK for C, both now in general availability (GA). The client-side SDK is designed for single-user contexts like desktop, mobile, and embedded applications, while the server-side SDK is intended for multi-user systems such as web application servers. These new SDKs expand LaunchDarkly's support to new sets of software, including client-side applications built on Node.js and server-side applications using C or C++. Users can refer to the documentation and reference guides for more information, and reach out to [email protected] with any questions.
