Building Secure APIs with Express: Authentication and Authorization Best Practices for jаvascript Apps is a comprehensive guide for developers aiming to create robust, secure, and scalable RESTful APIs using Express.js. This book demystifies the complexities of authentication and authorization, providing clear explanations of essential security concepts and hands-on implementation strategies. Readers will learn how to safeguard their applications from common threats such as injection attacks, cross-site scripting (XSS), and data breaches by leveraging proven middleware solutions like Passport.js and express-jwt.

The book covers the full authentication lifecycle, including password management, token-based authentication with JWT, multi-factor authentication, and integration with third-party identity providers such as Auth067. Detailed chapters walk through best practices for structuring Express apps, managing user roles and permissions, and implementing fine-grained access control. Real-world examples and code snippets help readers apply security measures effectively, ensuring their APIs are resilient against evolving threats. Whether you are new to Express.js or an experienced developer looking to enhance your security expertise, this book equips you with the knowledge and tools needed to build and maintain secure jаvascript APIs that protect both your users and your data.

Express.js serves as one of the most widely used web application frameworks in the jаvascript ecosystem. This section examines the security capabilities embedded within Express.js and how they form the foundation of secure API development. We’ll explore built-in protections, essential security middleware, and best practices for creating robust defenses against common vulnerabilities. Express provides a minimalist yet powerful approach to web security through its middleware architecture, allowing developers to incorporate various security layers. Understanding these core security features helps establish proper authentication and authorization systems while maintaining application performance. The section also covers handling sensitive data securely and the critical importance of maintaining updated dependencies to prevent security gaps.

Express.js has established itself as the de facto standard for building web applications and APIs with Node.js. Released in 2010, Express provides a thin layer of fundamental web application features without obscuring Node.js capabilities. This minimalist approach extends to security—Express provides some basic security features but relies on middleware to implement comprehensive security measures.
