What problem does it solve?
Pinia provides a robust, type-safe solution for managing application state in Vue apps, replacing ad-hoc stores or scattered state handling with a centralized, predictable API.
Core Features & Use Cases
- Defining stores via defineStore (Options or Setup) with state, getters, and actions; storeToRefs for safe destructuring; subscriptions; and a pattern-friendly architecture supporting plugins and SSR/Nuxt workflows.
- Extensibility and composability: plugin system, ability to compose stores and use Vue composables inside stores; SSR and Nuxt integration considerations.
- Use cases span small to large apps: shared state across components, server-side rendering hydration, devtools-friendly store inspection, and plugin-based store augmentation.
Quick Start
Create a simple setup store with defineStore and use it in a component to manage a counter.
