vuex VS pinia

Something I have already seen in many different code bases using frontend libraries like React and Vue is that developers use advanced state management solutions (e.g. Redux, Vuex, or Pinia) way too often.

Document address: Vuex official document

To avoid prop drilling we can make use of state management library like Vuex and Pinia, but for this article I will demonstrate of using Vue provide and inject. Let's refactor our components.

Flexibility: Vue is also flexible but provides more built-in solutions out of the box, such as Vue Router for navigation and Vuex for state management. This can reduce the need for additional libraries and make development more straightforward.

If you have been using Vue.js before 3.x you are probably familiar with Vuex now renamed Pinia. It allows you to have a centralized state that is shared across all your application components. If you have ever found yourself in situations where you are passing data/props between components and things are getting complicated, a centralized state is the answer.

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/

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).

Important !!! // tell all the stores you are contacting // Pinia instance, otherwise you will have problems because Pinia will access the global object // https://github.com/vuejs/pinia/blob/8626aac0049243de231401a01fe20092eeaf279c/packages/pinia/src/store.ts#L870 if (!authStore(pinia).isAuth) { return { path:'/login', status: 401, } } }

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
