How to handle github oauth response after github login?

Question

I have a Vuejs app that uses Github oauth to login. My current html exposes a button that logs in using github oauth. In this code when I click the button the Github oauth authorization dialog opens and is authorized. It then returns to my html app and I see a error in chrome console:

VM86700:1          POST http://localhost:3000/auth/github net::ERR_CONNECTION_REFUSED

The following is my config and is based from [vue-authenticate][1]:

import Vue from 'vue'
import App from './App.vue'

//import Vuex from 'vuex'
import VueAxios from 'vue-axios'
import VueAuthenticate from 'vue-authenticate'
import axios from 'axios';

import VueRouter from 'vue-router'
import cors from 'cors'
import vuetify from './plugins/vuetify';

const Home = { template: '<div>Home</div>' }

const router = new VueRouter({
  mode: 'history',
  routes: [
    { path: '/auth/github', component: Home },        
  ]
})

Vue.use(VueAxios, axios)

Vue.use(VueAuthenticate, {
  baseUrl: 'http://localhost:3000', // Your API domain

  providers: {
    github: {
      clientId: '<REDACTED>', 
      redirectUri: 'http://localhost:8080/auth/callback' // Your client app url 
      
    }
  }
})

Vue.config.productionTip = false

Vue.use(cors)

new Vue({
  router,
  vuetify,
  render: h => h(App)
}).$mount('#app')

Vue.use(VueRouter)

It seems like I need a handler to handle this redirection from github `http://localhost:3000/auth/github` but not sure how that is done.
