Stay ahead in web development with LabEx! A new project, "Adding Deprecation Warning to Vue Router," is available to help developers update their Vue Router 3.4.9 applications for the upcoming changes in Vue Router 4. The project focuses on identifying and modifying deprecated methods in the library, specifically the `addRoutes` method. By adding a deprecation warning, developers can smoothly transition to the new `router.addRoute()` method.
