To dispatch async data with Vue.js 3 store, you can follow these steps:

  1. Define an action in your store module that will handle the asynchronous logic. This action should return a promise so that you can handle the asynchronous data.

// store/module.js

export default {
  actions: {
    fetchDataFromApi({ commit }) {
      return new Promise((resolve, reject) => {
        // Make an asynchronous call to fetch data
        setTimeout(() => {
          const data = { name: 'John Doe', age: 30 };
          commit('setData', data);
          resolve();
        }, 1000);
      });
    }
  }
};


  1. Dispatch the action in your component. You can use store.dispatch to dispatch the action and handle the async data once the promise is resolved.

// MyComponent.vue

export default {
  mounted() {
    this.$store.dispatch('fetchDataFromApi')
      .then(() => {
        // Handle the async data once it is fetched
        console.log(this.$store.state.data);
      })
      .catch((error) => {
        // Handle any errors that occur during the async operation
        console.error(error);
      });
  }
};


  1. Ensure that the async data is stored in the store state by committing a mutation in the action.

// store/module.js

export default {
  state: {
    data: {}
  },
  mutations: {
    setData(state, data) {
      state.data = data;
    }
  }
};


By following these steps, you can dispatch async data in Vue.js 3 store and handle the data in your component once it is fetched asynchronously.
