Building Authentication with passport.js Chapter 6

const jwt = require('jsonwebtoken');

const passport = require('passport');

const passportJWT = require('passport-jwt');

const ExtractJwt = passportJWT.ExtractJwt;

const JwtStrategy = passportJWT.Strategy;

const jwtOptions = {}

jwtOptions.jwtFromRequest = ExtractJwt.fromAuthHeaderWithScheme('jwt');

jwtOptions.secretOrKey = 'movieratingapplicationsecretkey';

const app = express();

const router = express.Router();

The preceding code is enough to get us started. We will need

JwtStrategy from passport.js, and ExtractJwT will be used to extract the payload

data in the jwt token.

We have also defined a variable to set the JWT auth settings, which has a secret key

configured. This secret key will be used to sign the payloads of any requests.

You can also create a separate file to store your important keys.

Using the JWT strategy

Now we are all set up to use the services provided by passport.js. Let's quickly recap

what we have done so far:

1. Installed passport, passport-jwt, and jsonwebtoken


2. Configured all settings for these three packages

The next steps are as follows:

1. Creating our user model


2. Creating API endpoints for the user entity, that is, sign in and sign up


3. Building our authentication views, that is, the login page and register page


4. Using the JWT strategy to finally authenticate the requests

Setting up user registration

Let's start with adding the functionality to sign up users to our app.
