-# Authenticated Routes
+# Authenticated Routes with Nuxt.js
 
-> Nuxt.js can be used to create authenticated routes easily.
-
-## Using Express and Sessions
-
-To add the sessions feature in our application, we will use `express` and `express-session`, for this, we need to use Nuxt.js programmatically.
-
-First, we install the depedencies:
-```bash
-yarn add express express-session body-parser whatwg-fetch
-```
-
-*We will talk about `whatwg-fetch` later.*
-
-Then we create our `server.js`:
-```js
-const Nuxt = require('nuxt')
-const bodyParser = require('body-parser')
-const session = require('express-session')
-const app = require('express')()
-
-// Body parser, to access req.body
-app.use(bodyParser.json())
-
-// Sessions to create req.session
-app.use(session({
-  secret: 'super-secret-key',
-  resave: false,
-  saveUninitialized: false,
-  cookie: { maxAge: 60000 }
-}))
-
-// POST /api/login to log in the user and add him to the req.session.authUser
-app.post('/api/login', function (req, res) {
-  if (req.body.username === 'demo' && req.body.password === 'demo') {
-    req.session.authUser = { username: 'demo' }
-    return res.json({ username: 'demo' })
-  }
-  res.status(401).json({ error: 'Bad credentials' })
-})
-
-// POST /api/logout to log out the user and remove it from the req.session
-app.post('/api/logout', function (req, res) {
-  delete req.session.authUser
-  res.json({ ok: true })
-})
-
-// We instantiate Nuxt.js with the options
-const isProd = process.env.NODE_ENV === 'production'
-const nuxt = new Nuxt({ dev: !isProd })
-// No build in production
-const promise = (isProd ? Promise.resolve() : nuxt.build())
-promise.then(() => {
-  app.use(nuxt.render)
-  app.listen(3000)
-  console.log('Server is listening on http://localhost:3000')
-})
-.catch((error) => {
-  console.error(error)
-  process.exit(1)
-})
-```
-
-And we update our `package.json` scripts:
-```json
-// ...
-"scripts": {
-  "dev": "node server.js",
-  "build": "nuxt build",
-  "start": "NODE_ENV=production node server.js"
-}
-// ...
-```
-
-## Using the store
-
-We need a global state to let our application if the user is connected **across the pages**.
-
-To let Nuxt.js use Vuex, we create a `store/index.js` file:
-
-```js
-import Vue from 'vue'
-import Vuex from 'vuex'
-
-Vue.use(Vuex)
-
-// Polyfill for window.fetch()
-require('whatwg-fetch')
-
-const store = new Vuex.Store({
-
-  state: {
-    authUser: null
-  },
-
-  mutations: {
-    SET_USER: function (state, user) {
-      state.authUser = user
-    }
-  },
-
-  actions: {
-    // ...
-  }
-
-})
-
-export default store
-```
-
-1. We import `Vue` and `Vuex` (included in Nuxt.js) and we tell Vue to use Vuex to let us use `$store` in our components
-2. We `require('whatwg-fetch')` to polyfill the `fetch()` method across all browsers (see [fetch repo](https://github.com/github/fetch))
-3. We create our `SET_USER` mutation which will set the `state.authUser` to the conntected user
-4. We export our store instance to Nuxt.js can inject it to our main application
-
-### nuxtServerInit() action
-
-Nuxt.js will call a specific action called `nuxtServerInit` with the context in argument, so when the app will be loaded, the store will be already filled with some data we can get from the server.
-
-In our `store/index.js`, we can add the `nuxtServerInit` action:
-```js
-nuxtServerInit ({ commit }, { req }) {
-  if (req.session && req.session.authUser) {
-    commit('SET_USER', req.session.authUser)
-  }
-}
-```
-
-### login() action
-
-We add a `login` action which will be called from our pages component to log in the user:
-```js
-login ({ commit }, { username, password }) {
-  return fetch('/api/login', {
-    // Send the client cookies to the server
-    credentials: 'same-origin',
-    method: 'POST',
-    headers: {
-      'Content-Type': 'application/json'
-    },
-    body: JSON.stringify({
-      username,
-      password
-    })
-  })
-  .then((res) => {
-    if (res.status === 401) {
-      throw new Error('Bad credentials')
-    } else {
-      return res.json()
-    }
-  })
-  .then((authUser) => {
-    commit('SET_USER', authUser)
-  })
-}
-```
-
-### logout() method
-
-```js
-logout ({ commit }) {
-  return fetch('/api/logout', {
-    // Send the client cookies to the server
-    credentials: 'same-origin',
-    method: 'POST'
-  })
-  .then(() => {
-    commit('SET_USER', null)
-  })
-}
-```
-
-## Pages components
-
-Then we can use `$store.state.authUser` in our pages components to check if the user is connected in our application or not.
-
-### Redirect user if not connected
-
-Let's add a `/secret` route where only the connected user can see its content:
-```html
-<template>
-  <div>
-    <h1>Super secret page</h1>
-    <nuxt-link to="/">Back to the home page</nuxt-link>
-  </div>
-</template>
-
-<script>
-export default {
-  // we use fetch() because we do not need to set data to this component
-  fetch ({ store, redirect }) {
-    if (!store.state.authUser) {
-      return redirect('/')
-    }
-  }
-}
-</script>
-```
-
-We can see in the `fetch` method that we call `redirect('/')` when our user is not connected.
