vuex VS pinia

Pinia is a relatively new state management tool for the Vue ecosystem. It is the new preferred state management tool recommended by the Vue core team replacing Vuex. Compared to Vuex, Pinia is type-safe by default (direct-vuex was needed to make Vuex type-safe), extremely lightweight, and modular by design (meaning you can create multiple stores instead of multiple modules inside one store, which optimises performance). Similar to Vuex, Pinia has state, computed properties (getters) and methods (mutations and actions). Read more about Pinia and its usage to understand the similarities and differences between Pinia and Vuex.

Vue.js also offers built-in features like animation and state management through Vuex which serve a wide range of development needs.

I really liked the idea of how all the core Vue libraries are maintained by Vue team themselves, making Vue feels like an all-in-one package instead of infinite npm install to add multiple community/personally maintained repos which often caused issues because they don't blend together. And now Pinia will be officially replacing Vuex, making me doubt if it'll be as reliable as Vuex.

Pinia. No discussion. Have you checked the Vuex website? It says Pinia is default. https://vuex.vuejs.org/

Vuex itself, tells you to not use it and use Pinia instead.

Vuex is a state management library. At first glance it seems complicated, and in fact it is a bit. You can use Vuex to store data that should be used globally in your app. Vuex provides you with a solid API to apply changes to this data and reflect them in all child components that use Vuex data store.

I encourage you to also go through Vuex's official documentation: https://vuex.vuejs.org/

And in cases where you need globally available data, best to use Vuex, Pinia, or a composable

What makes Vue particularly powerful, however, is that it can be built upon, increasing its functionality from a simple view-model library to that of a fully fledged JavaScript framework capable of powering entire SPA's via supporting plugins and libraries such as Vue Router, Vue Resource, and Vuex.

Pinia tab is a feature integrated with Pinia, allowing you to view the registered modules and their details.

If you like Vuex, you'll love Pinia (the new official Vue state management library). At least, I enjoyed recently migrating my personal app from Vuex to Pinia. Pinia is even simpler / more straightforward than Vuex (and even more so compared to Redux).

When installing the "pinia" package via npm i pinia, I got a bunch of errors, similar to what's described here. This seems to be an issue with npm. Solution to that : install using yarn add -D pinia

Does using the main branch of pinia fix your issue? Over aggressive unwrapping was changed in https://github.com/vuejs/pinia/pull/1444

Also, I tried one syntax based on : https://github.com/vuejs/pinia/discussions/1096
