Tggl Client SDK

The `tggl-client` package provides a TypeScript SDK for integrating Tggl feature flags into both client-side (browsers, React Native) and server-side (Node.js) applications. Currently at version 3.2.2, the library maintains an active release cadence with frequent updates and bug fixes, as evidenced by recent v3.x releases. Version 3 represents a complete rewrite focused on improved reliability, fault tolerance, and maintainability, introducing a simpler API, better error handling, and automatic HTTP retries via `ky`. A key differentiator is its enforcement of feature flag best practices, specifically by removing the `isActive` method and making the default value a required argument for the `get` method since v2.0.0, guiding developers to always handle the absence of a flag gracefully. It also offers built-in storage options for Postgres, Redis, and Static storage for server-side usage, requiring corresponding peer dependencies like `pg` or `redis` for these features. The SDK supports Node.js environments version 20.0.0 and above.
