This article mainly explains "what is the workflow of Vuex". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how the workflow of Vuex is.

Vuex Foundation

1.Vuex is equivalent to vue's data warehouse.

2.Vuex is the state management tool of vue

State in 3.Vuex can only be changed through mutations

4.Vuex is very suitable for shopping cart.

What is Vuex?

Vuex stores the data state of all components centrally, and the intermediate state and store (background data) are responsive.

What is a response?

The foreground component data has changed, the background store data will change, resulting in the root of this component will change, so it is very suitable to be a shopping cart.

What are the benefits of Vuex? And usage scenarios?

Benefits: you can do state management and use LocalStorage to save information, and the data will always be stored in the user's client.

Usage scenarios: suitable for use in large and complex projects.

What are the advantages of Vuex?

The state storage of 1.Vuex is responsive

two。 It is a collection of states for all components

The Core and function of Vuex

Core concept: state,getters,mutation,action,module

Function: data communication between components, centralized management of data using one-way data flow

Describe in detail the operation mechanism of Vuex

The state storage of Vuex is responsive. When the Vuex component reads from the store, if the store state changes, the responding component will also update the state, but directly change the state, you must track the change of each state through the commit mutaions displayed.

Flow chart of Vuex:

1. Every point is necessary. If you don't execute that, you can omit it, but you must follow the flow chart.

The workflow of Vuex:

In the vue component, actions is triggered to submit modified data operations through dispatch, and then mutations is triggered to modify data through actions's commit. When mutations receives a request from commit, it automatically modifies the data in state through mutate. Finally, store triggers the update of each component that calls it.

Status of Vuex:

1.state: even the data warehouse is also the place where our warehouse stores data.

If our component wants to modify the data, the correct operation procedure is:

two。 To check whether it is synchronous or asynchronous, skip actions and modify the data of state directly from mutations, so that after the data of state warehouse is modified, we can respond correctly to the component, so the component can just submit the event to mutationd and let the mutations method of Vuex execute.

Thank you for your reading, the above is the content of "what is the workflow of Vuex". After the study of this article, I believe you have a deeper understanding of how the workflow of Vuex is, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
