Protecting routes based on authentication and authorization is essential for secure Vue applications, ensuring only authorized users can access restricted pages. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented route protection in numerous Vue admin dashboards and enterprise applications. From my 25 years of experience in web development and 11 years with Vue, the most effective approach is to use Vue Router’s navigation guards with authentication checks. This pattern provides flexible access control and seamless user redirection.
