What is the best way to integrate an asynchronously initialized API with a Vuex state?

Question

What is the best way to integrate an asynchronously initialized API with a Vuex state?

As I delve into the world of Vue + Vuex, I find myself grappling with the challenge of initializing an API that relies on asynchronous methods.

The common solutions I've attempted so far have hit roadblocks - can't use await outside an async function and exporting a promise doesn't sit well with Vue.

I aim to leverage the 'handle' component within my actions for handling async requests, but this is contingent upon the resolution of 'handle' itself.

I'm struggling to determine the optimal placement for this initialization process. One option is to initialize 'handle' globally before starting the Vue app, but this spatial separation from its usage feels awkward. Are there established approaches for tackling such scenarios?

Your insights would be immensely valuable!

To make actions asynchronous, you can store a reference to the promise returned by system.Initialize() and then wait for that promise to resolve before executing each action.

import { RequestSystemProxy } from '../../assets/scripts/RequestSystemProxy'

const system = new RequestSystemProxy()
const initPromise = system.Initialize()

const state = { ... }

const getters = { ... }

const mutations = { ... }

const actions = {
  async exampleAction (context) {
    const handle = await initPromise
    // now you can use handle 
  }
}

export default {
  state,
  getters,
  actions,
  mutations
}

Alternatively, you can have your module (let's call it store.js) export a promise

import { RequestSystemProxy } from '../../assets/scripts/RequestSystemProxy'

const system = new RequestSystemProxy()

export default system.Initialize().then(handle => {
  // initialize your store here...

  return {
    state,
    getters,
    // etc

  }
})

Then, consume the promise in your main.js file or wherever you need

import storePromise from 'path/to/store.js'

storePromise.then(store => {
  new Vue({
    store,
    // etc
  }).$mount('#app')
})

Note: Keep in mind how you will handle the UI before the root Vue instance is initialized and mounted.

It is important to define actions (which are essentially methods) within your store.

const actions = {
  async actionName({ state }) {
    // add your code here
  },
}

You can also include this:

export default {
  namespaced: true,
  state,
  getters,
  actions,
  mutations
};
