Abstract

This paper addresses the critical need for designing secure JavaScript applications by presenting both a foundational architectural overview and practical guidelines for implementation. The first part contrasts classical multi-page approaches with Single Page Application (SPA) paradigms, emphasizing the unique security challenges SPA-based systems face when handling user input and persistent session data. It then examines how microservices and containerization can strengthen reliability and fault isolation, provided that service-to-service communication is rigorously authenticated and monitored. The second part shifts focus toward a holistic development lifecycle, grounded in DevSecOps principles, with comprehensive use of automated testing, static analysis, and secure storage of credentials. Illustrated code snippets exemplify real-world defensive measures, including environment-based secret management and HTTP security headers. Collectively, this study underscores the importance of layered safeguards that extend from front-end frameworks to server-side architectures, thus enabling robust and maintainable JavaScript solutions.


Keywords: JavaScript Security, Single Page Application (SPA), Microservices, DevSecOps, Secure Coding, CSP, Containerization, Authentication, Access Control.
