@types/passport-local

What is @types/passport-local?

@types/passport-local provides TypeScript type definitions for the passport-local strategy, which is a Passport.js strategy for authenticating with a username and password.

What are @types/passport-local's main functionalities?

LocalStrategy

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

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

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, { message: 'Incorrect username.' }); }
      if (!user.validPassword(password)) { return done(null, false, { message: 'Incorrect password.' }); }
      return done(null, user);
    });
  }
));

Serialization and Deserialization

This feature allows you to serialize and deserialize user information to maintain authentication state across HTTP requests. The code sample shows how to implement these methods with Passport.js.

passport.serializeUser(function(user, done) {
  done(null, user.id);
});

passport.deserializeUser(function(id, done) {
  User.findById(id, function (err, user) {
    done(err, user);
  });
});

Middleware Integration

This feature allows you to integrate Passport.js middleware into an Express application. The code sample demonstrates how to set up session management and authentication routes.

const express = require('express');
const passport = require('passport');
const app = express();

app.use(require('express-session')({ secret: 'secret', resave: false, saveUninitialized: false }));
app.use(passport.initialize());
app.use(passport.session());

app.post('/login', passport.authenticate('local', { successRedirect: '/', failureRedirect: '/login' }));

@types/passport

@types/passport provides TypeScript type definitions for the core Passport.js library. It is essential for adding type safety to your Passport.js authentication strategies and middleware.

@types/passport-jwt

@types/passport-jwt provides TypeScript type definitions for the passport-jwt strategy, which is used for authenticating with JSON Web Tokens (JWT). It is useful for applications that use token-based authentication instead of session-based.

@types/passport-google-oauth20

@types/passport-google-oauth20 provides TypeScript type definitions for the passport-google-oauth20 strategy, which is used for authenticating with Google OAuth 2.0. It is useful for applications that want to allow users to log in using their Google accounts.
