vue-router-best-practices

Vue Router navigation guards often fail to fire on param changes because the same component is reused. You should use onBeforeRouteUpdate or watch route params to detect updates and prevent stale component state during client-side navigation.

To handle async navigation guards in Vue Router without hangs, you must await promises and return route objects to redirect. Replacing deprecated next() usage with proper async/return patterns prevents hangs and double-calls during client-side navigation.

The execution order of Vue Router guards follows a specific sequence: global, per-route, then in-component guards. Understanding this ordering helps enforce entry vs update scenarios and apply route-level validation correctly during navigation.

To fix infinite redirect loops in Vue Router auth checks, add escape hatches to your navigation guards and verify redirect conditions. Practical checks prevent redirect loops during async auth checks and route-level validation.

beforeRouteEnter does not have direct access to the component instance in Vue Router 4. You must use the next callback with a vm argument to access the instance, avoiding common beforeRouteEnter access misconceptions.

The best way to prevent stale UI when reusing a component for different route params is using onBeforeRouteUpdate, watching route params, or applying keys to force re-creation. These strategies prevent stale data during param changes.
