Does vue3.0 still use vuex?

In recent years, Vue.js, as an open source JavaScript front-end framework, has gradually become the first choice of many enterprises and individual developers, and has received widespread attention. Among them, Vuex, as a state management library of Vue.js, is also widely used by developers. It provides a centralized storage management method, allowing developers to better manage state and share data. However, with the release of Vue.js 3.0, many developers began to question: Do Vue 3.0 still need to use Vuex?

First, let’s take a look at the new features of Vue 3.0. Vue 3.0 mainly improves performance, especially in responsive systems. Vue 3.0 also adds many new APIs, such as Composition API, Teleport, etc. Among them, the Composition API deserves special attention because it provides a new component logic reuse mechanism and allows for better logic separation. At the same time, Vue 3.0 introduces Proxy in the responsive system to better manage local state. Through these improvements, the performance of Vue 3.0 has been greatly improved, and the development process has become more convenient and faster.

So, in the face of these new changes, do we still need Vuex, the state management library?

First of all, we need to understand the main role of Vuex. Vuex is mainly used to manage state in Vue.js applications, including global state and the state of individual components. Through Vuex, we can easily manage and organize the state data in the Vue.js application and maintain the consistency of the data in the application. Vuex also provides many out-of-the-box APIs, such as mutations, actions, getters, etc., which can easily implement responsive updates of state, asynchronous calls and other functions.

However, in Vue 3.0, the Composition API provides a better way to organize state. The Composition API provides the setup() function, which can organize the data, methods, etc. in the component according to logic to better manage and reuse the state. In this way, in Vue 3.0, we can better organize code according to business logic and avoid overly centralized state management. In addition, the responsive system in Vue 3.0 also introduces Proxy, making local state management more convenient.

Of course, this does not mean that we can completely give up using Vuex. In some complex business scenarios, Vuex can still provide better state management. Also, in many existing projects we already use Vuex for state management, so deprecating it completely may introduce some unnecessary work. But in most cases, we don't need to rely too much on Vuex. Some of the new features of Vue 3.0 can better manage state.

Although Vue 3.0 has more improvements, using Vuex can still help in some scenarios. If your application requires strict state management, then using Vuex is still suitable. But in most cases, we can start to try to use the new features provided by Vue 3.0, such as Composition API and Proxy, for better state management. In short, we need to flexibly use various tools and technologies during the development process instead of sticking to a specific tool or framework.
