VUEX

Vuex is a centralized state storage for all routes and components used in a web application. Each of them will request data from State Management and then return the changed data. This reduces the number of errors and increases system security.

To retrieve data from a state, developers write getters, mutation setters to pass the changed state back, and actions that do not change the state but "mutate" it. All of this allows the application to automate data processing as much as possible, and simplifies the work of developers several times. If you don't use Vuex and store information about states somewhere else, you'll have to write memory-cleaning tools yourself, invent getters and setters, methods for extracting specific information, customize the work on different pages, and so on. Weeks reduces the work to a minimum of two lines of code and does all of the above automatically and without errors.

Vuex doesn't have to be one big document. With this tool, you can split your repository into several convenient parts. To do this, you just need to create a new directory or several, properly label them, showing Vuex that it now has new repositories. This is convenient for structuring data and working together on a project.

One of the advantages of Vue.js is the virtual DOM, which restores only those UI components whose state has changed. Vuex supports this reactivity by default, automatically triggering changes to the DOM. If you store data outside of it, you need a separate function to track changes, and the page will be redrawn completely in any case, which worsens the loading speed and prevents you from using an important advantage of the framework.
