You can use this simple plugin https://github.com/imcvampire/vue-axios. (This wrapper bind axios to Vue or this if you’re using single file component)

Then you can use axios like this :

import Vue from 'vue'
import { Notify, Loading } from 'quasar'
/*
export const someAction = (state) => {
}
*/
export const doLogin = (state,creds) => {
  state.commit('LOGIN')
  let email=creds.email
  let password=creds.password
  console.log(this.$axios)
  return Vue.axios
    .post('/auth/signin', {
      email,
      password
    })
    .then(r => {
      //console.log(r)
      //localStorage.setItem("token", "JWT");
      commit('LOGIN_SUCCESS')
      return r
    })
    .catch(e => {
      //console.log(e.response)
      Notify.create("Error: " + e.response.status)
      //localStorage.removeItem("token")
      commit('LOGOUT')
      return e
    })
}

export const doLogout = (state) => {
  localStorage.removeItem("token")
  commit(LOGOUT)
}
