vue-router-best-practices

To handle Vue Router param changes on the same route, use the beforeRouteUpdate in-component guard or onBeforeRouteUpdate. This ensures proper lifecycle management and prevents data staleness without triggering full component re-renders.

Infinite redirect loops in Vue Router navigation guards often occur from improper return semantics. Implementing return-based guard patterns and validating navigation decisions within global or per-route guards prevents these redirect cycles.

The best way to structure Vue Router guards is using return-based patterns for per-route guards like beforeEnter and global guards. This codifies correct return semantics to ensure robust navigation flows in Vue 3.

Use beforeRouteEnter when loading data before a component instance is created, and beforeRouteUpdate when reacting to route param changes on an existing component. Correct lifecycle-aware routing prevents data staleness.

This guidance specifically applies to Vue 3 projects using Vue Router 4. It covers param changes, per-route guards, and global guard strategies tailored for the Vue 3 ecosystem and Vue Router 4 features.
