Nuxt access store (in Module mode) from JS file

Question

I have an AuthService that I use in a namespaced store in my Nuxt app. I need to commit mutations from AuthService to the namespaced store but I can't figure out how to import the store into my AuthService.

I've seen examples where the store is imported into the JS file, but the store is explicitly defined in the Vue app. Because I'm using Nuxt with the Module mode for my store, I'm not sure of the root path where I can import my store into the AuthService file. As I understand it, Nuxt handles creating the root store and all the namespaced store behind the scenes when use "Module mode"

My Nuxt store directory includes index.js (which is empty) and auth.js which has the mutations I want to call from AuthService.

auth.js

import AuthService from '../firebase/authService'

const authService = new AuthService()

export const state = () => ({
  user: null
})

export const mutations = {
  setUser (state, user) {
    state.user = user
  }
}

export const actions = {
  async signUp ({ commit }, payload) {
    try {
      await authServices.createUser(payload)
      return Promise.resolve()
    } catch (err) {
      const notification = {
        duration: 5000,
        message: err.message,
        type: 'error'
      }
      commit('ui/activateNotification', notification, { root: true })
      return Promise.reject()
    }
  }
}

authService.js

import { fAuth, fDb } from './config'

// I think I need to import auth store here but I'm not sure how

export default class AuthClient {
  async createUser (payload) {
    try {
      const res = await fAuth.createUserWithEmailAndPassword(payload.email, payload.password)
      const { uid } = res.user
      const user = {
        ...payload,
        uid
      }
      await this._createUserDoc(user)
      this._initAuthListener()
      return Promise.resolve()
    } catch (err) {
      return Promise.reject(err)
    }
  }

  async _createUserDoc (user) {
    await fDb.collection('users').doc(user.uid).set(user)
  }

  _initAuthListener () {
    fAuth.onAuthStateChanged(async (user) => {
      try {
        if (user) {
          const userProfileRef = fDb.collection('users').doc(user.uid)
          const userProfileDoc = await userProfileRef.get()
          const { uid, userName } = userProfileDoc.data()

          // Here is where I want to call a mutation from the auth store

          this.store.commit('setUser', {
            uid,
            userName
          })
        } else {
          this.store.commit('setUser', null)
        }
      } catch (err) {
        console.log(err)
      }
    })
  }
}

In index.js file which is in store folder you need to return store like this

import Vuex from 'vuex'
const createStore = () => {
  return new Vuex.Store({
    state: {
      counter: 0
    },
    mutations: {
      increment (state) {
        state.counter++
      }
    }
  })
}

export default createStore

and in your authService.js file you need to import store like this

import $store from '~/store'

by this you will be able to access your store

$store.commit('setUser', null)

I hope this works for you

Important Note: you don't need to install vuex because it is already shipped with nuxtjs
