SDuX Vault Brings Headless State Management to Deno Without a UI Framework

SDuX Vault, a TypeScript state management library, can run entirely outside the browser using Deno, with no UI framework or DOM required. The library's core primitive, called a FeatureCell, functions as a typed state pipeline that works identically in a browser or a server-side runtime like Deno. Developers import the package via an npm specifier in Deno, initialize the Vault runtime once, and create cells to manage shared mutable state under async concurrency. Unlike Redux, which ties its store to a component tree and assumes a browser render loop, SDuX Vault targets the owning cell instance directly and makes no runtime assumptions. The approach is aimed at use cases such as CLI batch processing, cache hydration, and edge functions that require consistent state management without any rendering layer.
