vue-router-best-practices

To handle Vue Router param changes without remounting, use the in-component guard onBeforeRouteUpdate. This allows your Vue 3 component to react to param or query changes dynamically without re-creating its lifecycle.

The best way to structure Vue Router navigation guards is by combining global beforeEach hooks with per-route beforeEnter guards. This pattern ensures secured, predictable routing behavior across your Vue 3 application.

No, this Vue Router guidance does not apply to Vue 2 projects. It specifically targets Vue 3 applications using Vue Router 4, focusing on modern route guards, lifecycle interactions, and async handling patterns.

You manage async operations inside Vue Router navigation guards by returning Promises or utilizing async/await within your guard functions. This ensures the navigation waits for your asynchronous logic to resolve before proceeding.

Your Vue 3 component lifecycle does not trigger because Vue Router reuses the same component instance for param changes by default. Implement onBeforeRouteUpdate to respond to these in-component updates without a full remount.

Common gotchas when implementing Vue Router per-route guards include improper async handling and unexpected navigation cancellations. Using reference-driven patterns for beforeEnter guards helps resolve these edge cases predictably.
