Instructions

---

At the end of this activity you should have successfully implemented Authentication with passport Local Strategy (username and password) by completing the TODOs in server.js and routes/index.js.

To install this starter code on your computer, clone the repository and install dependencies with

npm install

1. Create a .env file and include the values for port and private key. Check the .env-sample file for reference.

2. In server.js on line 15 inside the the passport.use() method, configure passport local strategy.

   • instantiate the LocalStrategy object - new LocalStrategy().
   • pass an anonymous function as its only argument - new LocalStrategy(()=>{})
   • pass username, password and cb(callback function) as the arguments in the anonymous function - new LocalStrategy((username, password, cb) =>{})
   • put the database query method implementation (db.findByUsername()) in the block of the localstrategy object.
   • Your code should end up looking like this:

   passport.use(new LocalStrategy((username, password, cb) => {
   db.findByUsername(username, (err, user) => {
       //code to verify user with password here
       // return callback function invoked with a user object - cb(null, user)
   }));

3. In server.js, with passport.serializeUser() function and using the user.id object, configure passport to serialize users.

4. In server.js on line 46, with passport.serializeUser() function and using the user.id object, configure passport to serialize users.

5. In server.js line 82, initialize passport with the passport.initialize() function.

6. In server.js line 83, include the passport.session() function to restore authentication state from the session.

7. Complete the logout route in routes/index.js. Use the req.logout() method passport provides. See reference here.

8. Start the server. Make sure you are in the project's directory in our terminal:

npm start

Open a web browser and navigate to http://localhost:3000/ to see the code in action.

Log in with either of these details:

username: amy, password: strings

OR

username: anne, password: secret
