To use async and await in the action object in Vuex, you need to follow these steps:

  1. Define an action in your Vuex store:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
const actions = {
  async fetchData({ commit }) {
    try {
      const response = await axios.get('your-api-url');
      commit('setData', response.data);
    } catch (error) {
      commit('setError', error.message);
    }
  }
}


  1. In the above example, the fetchData action uses async keyword and await keyword to wait for the asynchronous axios.get request to complete. This way, the action will pause until the promise is resolved or rejected.
  2. Inside the try block, you can access the response data and commit a mutation to update the state by calling the commit method.
  3. In case of any errors, the catch block will be executed. You can handle the error by committing a mutation to update the error state.
  4. Call the action from a component:
1
2
3
4
5
methods: {
  fetchData() {
    this.$store.dispatch('fetchData');
  }
}


  1. In your component, call the action by dispatching it using this.$store.dispatch method. The action name should match the one defined in your store.


By using async and await in the action object, you can write asynchronous code more elegantly and handle the response or errors appropriately.
