HomeWeb Front-endFront-end Q&Avue cannot be used in multiple applications

Vue is a popular JavaScript framework created by Evan You. The development purpose of Vue is to provide a lightweight Javascript framework that can help developers build large-scale applications. Although Vue is powerful, it also has some constraints and limitations. One of the most obvious limitations is that Vue cannot be used in multiple applications at the same time.

Vue’s single-application limitation was designed by its creators. It is designed to maintain the integrity of the interface state. In Vue, each instance is treated as a single application, and there is no shared state between different instances. This design makes Vue more reliable and efficient, but it also means developers need to carefully consider how to organize applications and instances.

Although Vue is only used in a single application, it can still realize the benefits of modular development through the use of components. A component in Vue refers to a self-contained logical unit with its own template, data and behavior. Components can be nested within other components or shared between different applications.

In Vue, the data and behavior of the component are encapsulated inside the component, which means that the component can be shared between different applications without conflict. This componentized design enables Vue to implement applications that are highly reusable and maintainable.

Although Vue cannot be used in multiple applications at the same time, it can be used with other frameworks or libraries. For example, Vue can be used with React to build different parts of the application. In this case, the Vue component can be part of the React component and can share data and state.

In general, Vue’s single application limit is to ensure the state integrity and reliability of the application. Although these limitations can create some challenges in some cases, using Vue's modular and component-based design, as well as collaboration with other frameworks and libraries, can result in efficient and maintainable applications.
