@nestjs/passport

What is @nestjs/passport?

@nestjs/passport is a NestJS module that provides integration with the Passport authentication middleware. It allows developers to implement various authentication strategies in a NestJS application, such as local, JWT, OAuth, and more.

What are @nestjs/passport's main functionalities?

Local Authentication

This feature allows you to implement local authentication using a username and password. The code sample demonstrates how to set up a local strategy with Passport.

const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;

passport.use(new LocalStrategy(
  function(username, password, done) {
    User.findOne({ username: username }, function (err, user) {
      if (err) { return done(err); }
      if (!user) { return done(null, false); }
      if (!user.verifyPassword(password)) { return done(null, false); }
      return done(null, user);
    });
  }
));

JWT Authentication

This feature allows you to implement JWT authentication. The code sample demonstrates how to set up a JWT strategy with Passport.

const passport = require('passport');
const { Strategy: JwtStrategy, ExtractJwt } = require('passport-jwt');

const opts = {
  jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
  secretOrKey: 'your_jwt_secret'
};

passport.use(new JwtStrategy(opts, function(jwt_payload, done) {
  User.findById(jwt_payload.sub, function(err, user) {
    if (err) {
      return done(err, false);
    }
    if (user) {
      return done(null, user);
    } else {
      return done(null, false);
    }
  });
}));

OAuth Authentication

This feature allows you to implement OAuth authentication using providers like Google. The code sample demonstrates how to set up a Google OAuth strategy with Passport.

const passport = require('passport');
const GoogleStrategy = require('passport-google-oauth20').Strategy;

passport.use(new GoogleStrategy({
  clientID: 'YOUR_GOOGLE_CLIENT_ID',
  clientSecret: 'YOUR_GOOGLE_CLIENT_SECRET',
  callbackURL: 'http://www.example.com/auth/google/callback'
},
function(token, tokenSecret, profile, done) {
  User.findOrCreate({ googleId: profile.id }, function (err, user) {
    return done(err, user);
  });
}));

express-session

Express-session is a middleware for managing sessions in Express applications. While it does not provide authentication strategies like @nestjs/passport, it is often used in conjunction with Passport to manage user sessions.

jsonwebtoken

Jsonwebtoken is a library for generating and verifying JSON Web Tokens (JWT). It is often used in combination with Passport's JWT strategy to handle token-based authentication. Unlike @nestjs/passport, it does not provide a complete authentication framework but focuses on JWT handling.
