title: using passportjs passport.authenticate() in Sapper route or sapper middleware
body: <p>I used passportjs in the past with expressjs and currently I'm trying to incorporate it with Sapper app but I'm unable to figure out how to inlcude the passport.authenticate() in my route because it's a sapper route not an express route. Also if I try to run everything in my server.js file I run into the issue of how to integrate it with the sapper middleware.
  How do you use passport.authenticate() in/with Sapper middleware or sapper routes js files (which is the front not server routes)?</p>
  
  <p>My server.js is typical:</p>
  
  <pre><code>const sirv = require('sirv');
  import express from 'express';
  var cookieParser = require('cookie-parser');
  import * as sapper from '@sapper/server';
  const session = require('express-session');
  var passport = require('passport');
  var mongoose = require('mongoose');
  mongoose.connect('mongodb://localhost/passport', { 
   useNewUrlParser: true });
  const MongoStore = require('connect-mongo')(session);
  const bodyParser = require('body-parser');
  
  const app = express();
  app.use(bodyParser.json());
  app.use(bodyParser.urlencoded({ extended: false }));
  app.use(cookieParser());
  
  app.use(session({
      secret: 'keyboard cat',
      resave: false,
      saveUninitialized: true,
      store: new MongoStore({ url: 'mongodb://localhost/passport' }),
      cookie: { secure: false, maxAge: 1000 * 60 * 60 * 24 * 7 }
  }));
  app.use(passport.initialize());
  app.use(passport.session());
  
  const { PORT, NODE_ENV } = process.env;
  const dev = NODE_ENV === 'development';
  
  const assets = sirv('static', {
      maxAge: 31536000, // 1Y
      immutable: true
  });
  
   app.use(assets, sapper.middleware({
      session: req =&gt; ({
          user: req.session &amp;&amp; req.session.user
      })})).listen(process.env.PORT, err =&gt; { if (err) console.log('error', err); });
  </code></pre>
  
  <p>As you can see, Sapper is just a middleware so if I want to authenticate a user and send it to the front/sapper, I need to figure out how to run passport.authenticate() inside the middleware function, right? </p>
  
  <p>If I want to use passport in the route JS file which is sapper front route:</p>
  
  <pre><code>//How to import passport.js here to make passport.authenticate() middleware available?
  import passport from './passport';
  import User from './mongoso';
  
  export async function post(req, res, next) {
  
      res.setHeader('Content-Type', 'application/json');
      /* Retrieve the data */ 
      var data = req.body;
  
  
      req.session.user = data.email;
      console.log("Here's the posted data:", data);
      console.log("information in the session is:", req.session);
  
      /* Returns the result */
      return res.end(JSON.stringify({ Email: req.session.user }));
      //return res.json({ data: data });
  
  }
  </code></pre>
  
  <p>Any ideas?  Greatly appreciated if someone out there could help. </p>
