Modern frontend frameworks like React, Vue, and Angular each have their security considerations and vulnerabilities. This course focuses on practical security implementation across these major frameworks, including common exploits through package dependencies.

You’ll learn to identify and fix vulnerabilities in package.json, implement protection against XSS and CSRF attacks, and prevent spoofing across different frameworks. Through hands-on exercises, you’ll build secure applications using framework-specific features and frontend security best practices.

After completing this course, you can develop secure applications across React, Vue, and Angular, audit dependencies for vulnerabilities, and implement robust security measures—essential skills for building production-ready frontend applications.
