Overview

Passport is a lightweight authentication middleware for Node.js that is widely used in the Node.js community. It is designed to be flexible and modular, allowing you to choose and implement the authentication strategies that best fit your application's requirements.

This repository provides a structured and well-documented foundation for implementing Passport authentication in your project. It includes pre-configured examples and best practices to help you get started quickly.

Installation

To install the Passport Authentication Repository, follow these steps:

1. Clone the repository: git clone https://github.com/kunaldhongade/PassportAuth-repo.git
2. Change into the project directory: cd PassportAuth
3. Install dependencies: npm install

Configuration

Environment Variables

Before using Passport in your project, make sure to set up the required environment variables. These variables include:

• SECRET_KEY: A secret key used to sign and verify JWT tokens.
• DATABASE_URL: The URL of your database.
• SESSION_SECRET: A secret used to initialize session middleware.

Passport Configuration

Passport requires minimal configuration. However, you may customize the configuration based on your specific needs. Update the passport-config.js file to include the desired authentication strategies and configure them accordingly.

Usage

Incorporating Passport into your application is straightforward. Import the Passport module and initialize it in your main application file. Use Passport middleware to authenticate requests, and configure routes to handle login, logout, and user registration.

// app.js

const express = require("express");
const passport = require("passport");
const session = require("express-session");
const passportConfig = require("./passport-config");

const app = express();

// Set up session middleware
app.use(
  session({
    secret: process.env.SESSION_SECRET,
    resave: true,
    saveUninitialized: true,
  })
);

// Initialize Passport
app.use(passport.initialize());
app.use(passport.session());

// Configure Passport
passportConfig(passport);

// Your routes and other middleware here

// Start your server
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});

Strategies

Passport supports a variety of authentication strategies, including:

• Local Strategy
• OAuth Strategies (Google, Facebook, Twitter, etc.)
• OpenID Connect Strategy
• JWT Strategy

Choose the strategies that best suit your application's requirements and configure them in the passport-config.js file.

Google OAuth Strategy

Overview

The Google OAuth strategy allows users to sign in to your application using their Google credentials. This is achieved by redirecting users to Google's authentication endpoint, where they log in and grant permission for your application to access their Google profile information.

Configuration

To configure Google OAuth in your Passport implementation, follow these steps:

1. Create a Project in Google Cloud Console:

   • Navigate to the Google Cloud Console.
   • Create a new project and enable the "Google+ API" in the API library.

2. Set up OAuth Credentials:

   • In your project, go to the "Credentials" page.
   • Create credentials and select "OAuth client ID."
   • Choose the application type (web application), set the authorized redirect URI, and create the client ID and client secret.

3. Install Passport Google OAuth Strategy:

   npm install passport-google-oauth20

4. Configure Passport:

   const passport = require("passport");
   const GoogleStrategy = require("passport-google-oauth20").Strategy;
   
   passport.use(
     new GoogleStrategy(
       {
         clientID: process.env.GOOGLE_CLIENT_ID,
         clientSecret: process.env.GOOGLE_CLIENT_SECRET,
         callbackURL: process.env.GOOGLE_CALLBACK_URL,
       },
       (accessToken, refreshToken, profile, done) => {
         // Handle user authentication and retrieval here
         // Profile object contains user information
         return done(null, profile);
       }
     )
   );

5. Integrate Google Strategy in Your Routes:

   app.get(
     "/auth/google",
     passport.authenticate("google", { scope: ["profile", "email"] })
   );
   
   app.get(
     "/auth/google/callback",
     passport.authenticate("google", { failureRedirect: "/" }),
     (req, res) => {
       // Successful authentication, redirect to success page
       res.redirect("/success");
     }
   );

GitHub OAuth Strategy

Overview

The GitHub OAuth strategy allows users to sign in using their GitHub credentials. Similar to Google OAuth, this involves redirecting users to GitHub's authentication endpoint for login and permission granting.

Configuration

To configure GitHub OAuth in your Passport implementation:

1. Create a GitHub Developer Application:

   • Visit GitHub Developer Settings.
   • Create a new OAuth App and provide the necessary details.
   • Set the Authorization callback URL.

2. Install Passport GitHub OAuth Strategy:

   npm install passport-github

3. Configure Passport:

   const passport = require("passport");
   const GitHubStrategy = require("passport-github").Strategy;
   
   passport.use(
     new GitHubStrategy(
       {
         clientID: process.env.GITHUB_CLIENT_ID,
         clientSecret: process.env.GITHUB_CLIENT_SECRET,
         callbackURL: process.env.GITHUB_CALLBACK_URL,
       },
       (accessToken, refreshToken, profile, done) => {
         // Handle user authentication and retrieval here
         // Profile object contains user information
         return done(null, profile);
       }
     )
   );

4. Integrate GitHub Strategy in Your Routes:

   app.get("/auth/github", passport.authenticate("github"));
   
   app.get(
     "/auth/github/callback",
     passport.authenticate("github", { failureRedirect: "/" }),
     (req, res) => {
       // Successful authentication, redirect to success page
       res.redirect("/success");
     }
   );

OpenID Connect Strategy

Overview

OpenID Connect (OIDC) is a simple identity layer on top of the OAuth 2.0 protocol. It allows clients to verify the identity of the end user based on the authentication performed by an authorization server.

Configuration

To use OpenID Connect with Passport:

1. Install Passport OIDC Strategy:

   npm install passport-openidconnect

2. Configure Passport

const passport = require("passport");
const OpenIDConnectStrategy = require("passport-openidconnect").Strategy;

passport.use(
  new OpenIDConnectStrategy(
    {
      issuer: process.env.OIDC_ISSUER,
      authorizationURL: process.env.OIDC_AUTHORIZATION_URL,
      tokenURL: process.env.OIDC_TOKEN_URL,
      clientID: process.env.OIDC_CLIENT_ID,
      clientSecret: process.env.OIDC_CLIENT_SECRET,
      callbackURL: process.env.OIDC_CALLBACK_URL,
      userInfoURL: process.env.OIDC_USER_INFO_URL,
    },
    (issuer, sub, profile, accessToken, refreshToken, done) => {
      // Handle user authentication and retrieval here
      // Profile object contains user information
      return done(null, profile);
    }
  )
);

3. Integrate OIDC Strategy in Your Routes:

   app.get("/auth/oidc", passport.authenticate("openidconnect"));
   
   app.get(
     "/auth/oidc/callback",
     passport.authenticate("openidconnect", { failureRedirect: "/" }),
     (req, res) => {
       // Successful authentication, redirect to success page
       res.redirect("/success");
     }
   );

Customization

The repository is structured to allow easy customization. You can extend or modify existing authentication strategies, implement additional strategies, or enhance the user experience by customizing the login and registration views.

Security Considerations

Security is a crucial aspect of authentication. This repository follows best practices, such as password hashing, session management, and secure communication. However, it is essential to stay updated on security recommendations and regularly review and update your authentication implementation.
