Using Vuex 4 with Vue 3

Vuex remains a critical state management solution for Vue applications, even with the advancements introduced in Vue 3, such as the Composition API and Provide/Inject API, which offer new reactive features. Although these new features can handle some of Vuex's tasks, Vuex's robust debugging capabilities and structured plugin system make it indispensable, especially for complex applications. Vuex 4, the version compatible with Vue 3, continues to provide essential functionalities like states, mutations, actions, and getters, which help manage the global state effectively. Installation of Vuex 4 with Vue 3 can be done via script tags, and Vuex stores can be created to encapsulate application states, allowing developers to access and update these states using mutations and actions. Getters can also be used to simplify the retrieval of store states, providing an organized approach to manage state-dependent logic. While Vuex is well-suited for larger applications, smaller projects might benefit more from the Composition API's reactive features, making Vuex's necessity dependent on the complexity of the project.
