## What it is
Pinia is the official type-safe state management library for Vue, built on the Composition API with DevTools support and a modular, extensible design. It is extremely lightweight (~1.5kb), works with Vue 3 (and Vue 2 via the v2 branch), and integrates as a Nuxt module.

## Use cases
- manage global state in a Vue 3 app
- replace Vuex with a simpler type-safe store
- share reactive state between Vue components
- code-split multiple stores in a Vue application
- sync store state to localStorage in Vue
- use a state store with Nuxt SSR
- debug Vue app state with devtools

## When to choose
- you are building a Vue 3 or Nuxt application and need shared state
- you want full TypeScript inference and autocompletion in your store
- you want a tiny, modular store with devtools support
- you are migrating from Vuex and want the officially recommended successor

## When to avoid
- your project uses React, Angular, or Svelte rather than Vue
- you only need local component state with no cross-component sharing
- you need a framework-agnostic store that works outside the Vue ecosystem
