Learn Vuex with online courses and programs

Vuex makes it easier to manage and update the Vue.js state. Learn how to use Vuex for state management in applications to take your web development skills to the next level with edX.

What is Vuex?

Vuex is a state management library for Vue.js applications. It plays the role of a centralized store for managing the state of a Vue.js application. State management maintains knowledge of an application’s data flows and user inputs, such as text field inputs or button clicks.

Vuex follows the Flux pattern, where the state is kept in a single store, and any changes to the state are made through mutations.^{Footnote 1}

In a typical Vue.js application, components communicate through props and events. As the application grows, managing the state across components becomes more challenging. Vuex simplifies this process by providing a centralized store that all components in the application can access.

Vuex tutorial curriculum

If you are curious about how to learn Vuex, consider online courses. A beginner course might help you learn introductory concepts, such as:

The benefits of using Vuex
The difference between various state management libraries, such as Pinia versus Vuex
An overview of Vuex architecture
Ways to install Vuex
The advantages of using a single state tree

An intermediate Vuex course will begin to cover more advanced topics. This could include various helper functions and operators, such as Vuex mapState and object spread. Learners could also begin working with Vuex getters to retrieve data, as well as learning the difference between accessing getters via property style or method style. Additional topics covered at this level could include Vuex mutations and Vuex actions.

For experienced learners, an advanced Vuex course can cover:

Structuring a Vuex store for larger applications
Managing the store with an API
Committing mutations inside plugins and taking state snapshots
Using a built-in logger plugin
Enabling strict mode to catch state mutations outside of mutations

Learning how to use Vuex can supplement your knowledge of web and application development. edX offers a variety of educational opportunities for learners interested in studying these topics, as well as a host of other disciplines. A boot camp can provide flexible, hands-on learning for those who want to upskill quickly, while executive education courses are designed for busy professionals. You can also pursue a more comprehensive curriculum in a bachelor’s degree program or, for more advanced learners, a master’s degree program. Find the right learning path for you.

Frequently asked questions

When should I use Vuex?

If you are building a simple application, you may not need Vuex. A simple store pattern may be sufficient. However, for medium-to-large-scale, single-page applications, using Vuex can offer efficient state management outside Vue components and improve long-term productivity.^{Footnote 6} Ultimately, whether you use Vuex will depend on the projects’ needs, limits, and scale.

Is Vuex the same as Redux?

Vuex and Redux are similar in many ways. Their designers based both on the Flux patterns, but both do not strictly follow the pattern. However, they handle mutations differently. Redux employs reducers to manage state, while Vuex uses mutations. In Redux, state is always immutable, but in Vuex, the store commits mutations to change the data.^{Footnote 7}

Where does Vuex store data?

Vuex stores data in a centralized state container called the "store." The store is a plain JavaScript object containing the application's state.^{Footnote 8} All components in the application can access the state stored in the Vuex store and update the state by committing mutations or dispatching actions. This centralized approach to state management allows for a more predictable and maintainable codebase.

What is the difference between Vue and Vuex?

Vue.js is a progressive JavaScript framework that helps developers build user interfaces, while Vuex is a state management library designed explicitly for Vue.js applications.
