What are Vuex actions and how do I use them?

What are Vuex actions and how do I use them in my Vue.js app?

Vuex actions are functions that can perform asynchronous operations and commit mutations. They are used to handle complex logic.

Can you give me an example of how to define an action?

Sure! Here's a simple example:

const actions = {
  fetchData({ commit }) {
    // Simulate an API call
    setTimeout(() => {
      const data = 'Fetched data';
      commit('setData', data);
    }, 1000);
  }
};

How do I call this action from a component?

You can call the action using this.$store.dispatch('fetchData') in your component's method.

What are the differences between actions and mutations?

Actions can contain asynchronous code and can call multiple mutations, while mutations must be synchronous and only commit state changes.
