What to Expect When You're Expecting a LaunchDarkly SDK

LaunchDarkly offers a variety of SDKs that go beyond just wrapping API calls and provide additional layers of functionality. The SDKs are divided into two categories: client-side and server-side, with mobile SDKs also considered client-side. Client-side SDKs have different security requirements and bandwidth considerations compared to server-side SDKs. LaunchDarkly's SDKs ensure fast flag evaluation by using in-memory caching and streaming updates for both server-side and client-side applications. The SDKs also handle analytics data automatically, reducing load and limiting bandwidth usage. Additionally, the SDKs make it easy to configure additional settings such as persistent data stores and Relay Proxy. While the API can be used for more general actions or automations, the SDK is recommended for most use cases due to its efficiency and built-in features.
