This article introduces the relevant knowledge of "the five core attributes and functions of vuex". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The five core attributes of vuex are state, getters, mutations, actions, and modules. State is the basic data of vuex, which is used to store variables. Geeter is data derived from basic data, which is equivalent to the computational property of state.

The five core attributes in Vuex are: state, getters, mutations, actions, and modules.

Let's take a look at these five attributes.

Basic data of state:vuex, used to store variables

Geeter: data derived from basic data (state), equivalent to the computational properties of state

Mutation: the method for submitting updated data must be synchronous (if you need to use action asynchronously). Each mutation has an event type of a string (type) and a callback function (handler).

The callback function is where we actually make the state change, and it accepts state as the first parameter and commits the load as the second parameter.

Action: the function is roughly the same as that of mutation, except that = "1. Action submits the mutation instead of changing the state directly. 2. Action can contain any asynchronous operation.

Modules: modular vuex, which allows each module to have its own state, mutation, action and getters, making the structure very clear and easy to manage.

This is the end of the content of "five core attributes and functions of vuex". Thank you for your reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
