TypeScript Application Security: Protection from Vulnerabilities

In the modern world of web development, application security comes to the forefront. The book "TypeScript Application Security" is a comprehensive guide that will help TypeScript developers create secure, reliable, and attack-resistant applications. The author of the book, Andrey Sokolov, an experienced cybersecurity and TypeScript specialist, shares practical knowledge that can be immediately applied in real projects.

What is this book about?

The book covers the full range of security issues related to TypeScript development. You will learn:

• How to protect your application from the most common attacks: XSS (Cross-Site Scripting), SQL injections, CSRF (Cross-Site Request Forgery), and SSRF.
• How to properly use TypeScript typing to prevent vulnerabilities at the compilation stage.
• Methods for secure API work, including input validation, endpoint protection, and token management.
• Principles of secure secret storage, database interaction, and user session management.
• How to integrate security into the CI/CD pipeline and conduct code audits.

Who is this book for?

The book will be useful for:

• Frontend and backend developers using TypeScript (React, Angular, Node.js, Deno).
• Team leads and architects who want to foster a culture of secure development in their team.
• Students and juniors looking to master best security practices from the start.
• DevOps engineers responsible for the security of TypeScript project infrastructure.

What will you learn after reading?

After studying the book, you will be able to:

• Conduct code analysis for common vulnerabilities.
• Use built-in TypeScript features (strict mode, utility types, discriminated unions) to enhance security.
• Configure Content Security Policy (CSP), protection against clickjacking, and other HTTP headers.
• Implement secure authentication (OAuth 2.0, JWT) and authorization (RBAC, ABAC).
• Work with encryption, password hashing, and secure data storage.

The book is written in an engaging style, contains numerous code examples, checklists, and practical exercises. It will help you not only avoid common mistakes but also lay the foundation for a secure application architecture.

Who is this book not for? If you are just starting to learn programming and are not yet familiar with the basics of TypeScript, we recommend first completing a beginner course. The book assumes confident knowledge of the language and an understanding of web technologies.
