Pinia‑Scope is a small library that adds dynamic, hierarchical scoping to Pinia stores in Vue 3 applications. It lets you create multiple isolated instances of the same store (e.g., per‑preview, per‑order) by prefix‑ing a scope string to store IDs, automatically propagates the scope through component trees, and cleans up scoped stores when no longer used—making complex, reusable data layers easier to manage for Vue developers.
