Securing and Testing Node.js Applications

О курсе

This course helps learners transform working Node.js APIs into secure, maintainable, and production-ready backend applications. It focuses on the practical skills needed to protect APIs, organise backend code, manage configurations, test application behaviour, and deploy Node.js services to real-world environments. You'll begin by exploring authentication and API security, including the difference between authentication and authorisation, token-based authentication, and JWT authentication flow. From there, you'll implement login APIs, generate and verify JWT tokens, protect routes using middleware, apply role-based access control, and strengthen APIs using CORS and rate limiting. The course then moves into scalable backend architecture and maintainability. You'll learn how to structure Node.js applications by separating routes, controllers, and services. You will also work with centralised error handling, application logging, environment variables, and secure configuration practices to make backend systems easier to manage and maintain. Finally, you'll explore testing, deployment, and production operations. You'll write unit and integration tests, validate API responses, prepare applications for deployment, deploy backend services, and monitor application performance. These skills help bridge the gap between building an API and running it reliably in production. By the end of this course, you will be able to: - Explain authentication, authorisation, and token-based security in backend APIs. - Implement JWT authentication for login and protected routes. - Secure Express APIs using middleware, role-based access control, CORS, and rate limiting. - Structure scalable Node.js applications using routes, controllers, and services. - Apply centralised error handling, logging, and secure configuration practices. Designed for learners who can already build Node.js and Express APIs, this course is ideal for aspiring backend developers, full-stack developers, and software engineering learners who want to make applications secure, testable, and production-ready. Move beyond building APIs and learn how to secure, test, deploy, and maintain Node.js applications with confidence.
