Unlocking Global State Management with Vue3 Compositional Functions

As a seasoned frontend engineer with 15 years of experience, I have always been keeping an eye on the new features and state management solutions in Vue3. In a recent project, I experimented with using compositional functions to replace traditional state management libraries like Pinia and Vuex. This decision led me to delve deep into the power of Vue3's compositional API and how to utilize compositional functions for global state management.

In the project, I encountered the need to share state across multiple pages. Initially, I opted to install Pinia for state management. However, I soon realized that there was no need to introduce a separate state management library because Vue3's compositional functions already provided enough capability for global state management. Compositional functions leverage Vue's compositional API to encapsulate and reuse stateful logic functions, allowing the definition of state outside of components and its usage in any JS file.

For example, I defined the user information state in a compositional function. By using ref() to define the state and exposing it along with methods, I could import and use this state in any Vue3 component. This modular approach to state management showcased the convenience and flexibility of compositional functions.

In addition to state management, compositional functions can also achieve functionalities similar to React's Hooks. By modularizing the definition of a set of states, I could better organize and manage states in the project. Furthermore, using computed properties, I could also implement functionalities akin to getters in Pinia.

Overall, for ordinary projects, using compositional functions for state management is a great choice. It is concise, flexible, and can meet the state management needs of most projects. When asked by interviewers about alternative state management solutions apart from Pinia and Vuex, compositional functions are a great answer.

Throughout the process of writing this article, I delved into the usage methods and advantages of Vue3's compositional functions, compared them with traditional state management libraries, and discussed their applicability and considerations. Understanding and mastering these new features can not only enhance project development efficiency but also demonstrate a profound understanding of frontend technologies during interviews.

In future projects, I will continue to explore Vue3's new features, constantly learn and experiment with new technological solutions to enhance my expertise in the frontend field. The insights I gained from Vue3's compositional functions have inspired me, and I hope my experience and sharing can be helpful to other frontend engineers. Let's together explore the limitless possibilities of frontend technology!
