Alternatively, you can also install it via yarn:

yarn add authproxyjs

Configuration

Configuring AuthProxy.js involves setting up a few key parameters in your application's configuration file. Here is an example configuration:

const AuthProxy = require('authproxyjs');
const options = {
    // Path to the secret key used for signing/verifying tokens
    secretKey: 'your_secret_key',
    // Database connection string
    dbConnectionString: 'mongodb://localhost:27017/authdb',
    // List of allowed origins for CORS
    allowedOrigins: ['http://localhost:3000'],
    // Cookie settings
    cookieOptions: {
        maxAge: 3600 * 1000, // 1 hour
        secure: false,       // Set to true if using HTTPS
        httpOnly: true       // Prevents access to cookies via JavaScript
    }
};
const authProxy = new AuthProxy(options);

Integration with Express.js

To integrate AuthProxy.js with an Express.js application, follow these steps:

1、Install the necessary packages:

npm install express body-parser

2、Create an Express app and set up middleware:

const express = require('express');
const bodyParser = require('body-parser');
const AuthProxy = require('authproxyjs');
const app = express();
app.use(bodyParser.json());
const options = {
    secretKey: 'your_secret_key',
    dbConnectionString: 'mongodb://localhost:27017/authdb',
    allowedOrigins: ['http://localhost:3000'],
    cookieOptions: { maxAge: 3600 * 1000, secure: false, httpOnly: true }
};
const authProxy = new AuthProxy(options);
app.post('/login', async (req, res) => {
    const { username, password } = req.body;
    try {
        const token = await authProxy.login(username, password);
        res.json({ token });
    } catch (error) {
        res.status(401).json({ error: 'Invalid credentials' });
    }
});
app.listen(3000, () => {
    console.log('Server running on port 3000');
});

Middleware Example

You can also use AuthProxy.js as middleware to protect routes:

const protectedRoute = (req, res, next) => {
    const token = req.headers['authorization'];
    if (!token) {
        return res.status(401).json({ error: 'No token provided' });
    }
    try {
        const user = authProxy.verifyToken(token);
        req.user = user;
        next();
    } catch (error) {
        res.status(401).json({ error: 'Invalid token' });
    }
};
app.get('/protected', protectedRoute, (req, res) => {
    res.json({ message: 'This is a protected route', user: req.user });
});

Logging and Monitoring

AuthProxy.js comes with built-in logging capabilities. You can enable logging by adding thelogger option to your configuration:

const winston = require('winston');
const logger = winston.createLogger({
    level: 'info',
    format: winston.format.json(),
    transports: [
        new winston.transports.Console(),
        new winston.transports.File({ filename: 'authproxy.log' })
    ]
});
const options = {
    secretKey: 'your_secret_key',
    dbConnectionString: 'mongodb://localhost:27017/authdb',
    allowedOrigins: ['http://localhost:3000'],
    cookieOptions: { maxAge: 3600 * 1000, secure: false, httpOnly: true },
    logger: logger
};

Security Best Practices

When using AuthProxy.js, it is important to follow security best practices to ensure the safety of your application:

1、Use HTTPS: Always use HTTPS to encrypt data transmitted between the client and server.

2、Secure Cookies: Set thesecure option totrue when using HTTPS.

3、HttpOnly Cookies: Prevent JavaScript access to cookies by setting thehttpOnly option totrue.

4、CSRF Protection: Implement CSRF protection to prevent cross-site request forgery attacks.

5、Rate Limiting: Use rate limiting to prevent brute force attacks.

6、Regular Updates: Keep your software and libraries up to date to avoid known vulnerabilities.

7、Input Validation: Always validate and sanitize user inputs to prevent injection attacks.

8、Error Handling: Do not expose sensitive information in error messages.

9、Encryption: Encrypt sensitive data both at rest and in transit.

10、Access Control: Implement role-based access control (RBAC) to restrict access based on user roles.

11、Audit Logs: Maintain audit logs for tracking access and changes.

12、Password Policies: Enforce strong password policies and consider using multi-factor authentication (MFA).

13、Backup and Recovery: Have a plan for regular backups and disaster recovery.

14、Compliance: Ensure compliance with relevant regulations such as GDPR or CCPA.

15、Third-Party Services: Be cautious when integrating third-party services and ensure they follow security best practices.

16、Security Headers: Use security headers like Content-Security-Policy (CSP), X-Content-Type-Options, etc., to enhance security.

17、Session Management: Properly manage sessions, including setting appropriate timeouts and regenerating session IDs after login or privilege escalation events.

18、Environment Variables: Store sensitive information like database credentials and secrets in environment variables rather than hardcoding them into your application.

19、Monitoring: Continuously monitor your application for suspicious activities and respond promptly to any detected issues.

20、User Education: Educate users about safe practices such as recognizing phishing attempts and creating strong passwords.

21、Incident Response Plan: Have an incident response plan in place to quickly address any security breaches that may occur.

22、Penetration Testing: Regularly conduct penetration tests to identify potential vulnerabilities before they are exploited by attackers.

23、Code Reviews: Conduct regular code reviews with a focus on security to catch potential issues early on.

24、Least Privilege: Follow the principle of least privilege by granting users only the minimum permissions necessary for their tasks.

25、Dependency Checks: Use tools like Snyk or Dependabot to check for vulnerabilities in your project's dependencies and keep them updated accordingly.

26、Security Audits: Consider hiring a professional security auditor to perform periodic security assessments of your application and infrastructure.

27、Documentation: Maintain comprehensive documentation outlining all security measures implemented within your system so that future developers can understand and maintain these standards without compromising security.

28、Automated Tools: Leverage automated tools for static analysis, dynamic analysis, threat modeling, etc., during development cycles to proactively identify potential weaknesses before deployment.

29、Community Support: Engage with the community around AuthProxyJS or other similar projects to stay informed about latest threats, trends best practices and updates related to authentication and security in general.
