vue-pinia-best-practices

The "getActivePinia was called" error in Vue 3 occurs when Pinia is used before plugin installation. Resolve this initialization failure by correcting plugin order and preventing premature store usage in your main entry file.

Fix broken Pinia store reactivity by using the `storeToRefs` utility. Destructuring Pinia stores directly breaks UI updates because it loses reactivity, but wrapping the store with `storeToRefs` preserves reactivity for destructured properties.

Ensure Pinia state is available in Vue DevTools and SSR by properly exposing all state in your store definition. This compatibility prevents server-side rendering hydration mismatches and ensures complete state inspection during development.

A Pinia setup store is defined using a function that returns state and methods, similar to the Composition API. Correcting setup store syntax errors ensures that shared state, composables, and router navigation guards function properly across components.

Manage ephemeral filter state in Vue 3 by configuring Pinia stores to handle temporary UI state separately from persistent data. This prevents setup mistakes that break state persistence and ensures template method binding works correctly.
