What are Vuex store actions and how do I use them?

Vuex store actions are functions that can be called to perform asynchronous operations or complex logic before committing mutations. They are used to handle tasks like API calls.

Can you give me an example of a Vuex action?

Sure! Here's a simple example:

actions: {
  fetchData({ commit }) {
    return axios.get('/api/data')
      .then(response => {
        commit('setData', response.data);
      });
  }
}

How do I commit a mutation from an action?

You can commit a mutation from an action by using the commit method provided in the action's context. For example:

actions: {
  updateData({ commit }, newData) {
    commit('setData', newData);
  }
}

What is the difference between actions and mutations?

The main difference is that actions can contain asynchronous operations and can call multiple mutations, while mutations must be synchronous and are the only way to change the state.
