What is used for state management in vue development

Vue.js is currently one of the most popular frameworks in front-end development. The state management of Vue.js is a very critical part, which can help us deal with complex states in the application.

In Vue.js development, using Vuex for state management is the most common method. Vuex is a state management library specially developed for Vue.js applications. It can help us solve state management problems in applications.

The core concept of Vuex is store, which contains all states and state change logic in the application. The state in the store is reactive. When the state changes, all places that depend on the state are automatically updated. This makes it easier for us to manage status.

The state in Vuex is organized into a tree structure, and each node corresponds to a state object. In Vuex, we can define getters to obtain status, mutations to modify status, and actions to handle asynchronous operations.

Getters are used to get data from the state, similar to computed properties in Vue.js. A getter can accept another getter as a parameter, which allows us to easily share state data between getters.

mutations are used to modify state and are one of the core concepts in Vuex. Mutations can only be operated synchronously, not asynchronously. This allows us to track state changes, making our application more controllable.

actions are used to handle asynchronous operations, and they can call mutations to make state changes. Actions can contain asynchronous operations and logic, and can call API backend services to make data requests.

Vuex also provides some auxiliary functions, such as mapState, mapGetters, mapMutations and mapActions. These functions can help us use states and operations in Vuex more conveniently.

In addition to Vuex, other state management tools can also be used in the development of Vue.js, such as Mobx and Redux. These tools provide different status management methods and features, which can be selected according to the needs of the project.

In short, using Vuex for state management is one of the most common and convenient methods in Vue.js development. Vuex provides a simple yet powerful state management solution that can handle complex states in applications. With Vuex, we can develop Vue.js applications more easily, improving development efficiency and application quality.
