Not working in IE 11

I’ve created a sample project with latest vue-cli and added feathers libraries. Error on ie11 attached

api/feathers-client.js

import $config from '@/config'
import feathers from '@feathersjs/client'
import io from 'socket.io-client'
const socket = io($config.feathersServer, { transports: ['websocket'], upgrade: false })
const feathersClient = feathers()
feathersClient.configure(feathers.socketio(socket));
feathersClient.configure(feathers.authentication());
export default feathersClient

store/index.js

import Vue from 'vue'
import Vuex from 'vuex'
import feathersVuex from 'feathers-vuex'
import feathersClient from '../api/feathers-client'

const { service, auth, FeathersVuex } = feathersVuex(feathersClient, { idField: '_id' })

Vue.use(Vuex)
Vue.use(FeathersVuex)

export default new Vuex.Store({
    state: {
  
    },
    mutations: {
  
    },
    actions: {
  
    }
})

Hi there,

I’ve finally found a way. It’s working on the production in couple of days. I’ll create a clean project as a sample and share as soon as possible.

@stwessl and @cemevren, did you ever published a sample project with IE support?
