Description: Route Guards in Vue Router are functions that allow protecting routes in a Vue.js application before the user accesses them. These functions are executed before navigating to a new route, enabling the implementation of access control logic, such as authentication or authorization checks. Guards can be used to redirect users to a login page if they are not authenticated or to display an error message if they attempt to access a restricted route. There are several types of guards: global guards, which apply to all routes; per-route guards, defined in the configuration of a specific route; and component guards, which can be defined within a specific component. This flexibility allows developers to effectively manage security and navigation flow in their applications, enhancing user experience and ensuring that only authorized users access certain sections of the application.
