🚀 What’s New in Pinia 3?

Pinia 3 brings significant changes that reinforce its minimalist and optimized approach to Vue.js. Here are its main highlights:

1. Goodbye Vue 2

Pinia 3 no longer supports Vue 2 and is now fully focused on Vue 3. This means:

✅ Better integration with the Composition API.
✅ Full advantage of Vue 3’s modern features.
✅ Increased efficiency with less legacy code.

If you're still using Vue 2, now is the time to upgrade and take advantage of Vue 3 and Pinia’s benefits.

2. Enhanced TypeScript Support

The TypeScript integration has been refined, offering:

✅ Stronger typing.
✅ Better autocomplete in editors like VS Code.
✅ Fewer runtime errors.

Thanks to these improvements, working with Pinia and TypeScript is now smoother and more reliable.

3. Stable and Minimalist API

Pinia maintains its philosophy of being simple and straightforward, but in this version:

✅ Deprecated APIs like PiniaStorePlugin have been removed.
✅ The API has been optimized for greater clarity and ease of use.
✅ Less unnecessary code, more productivity.

If you were already using Pinia, upgrading to this new version is virtually seamless.

4. Full Compatibility with Vue DevTools

Debugging and tracking state in Vue 3 remains easy because Pinia 3 is fully compatible with Vue DevTools.

✅ See real-time state changes.
✅ Easily explore your store’s structure.
✅ Better development experience with no additional setup.

5. Recommended Data Persistence

Although Pinia does not include built-in persistence, it officially recommends using pinia-plugin-persistedstate to handle state storage in localStorage or sessionStorage.

If you need persistence in your application, this plugin is the best solution.
