Frequently Asked Questions about vue-router-best-practices

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is the difference between per-route guards and in-component guards in Vue Router?▼

Per-route guards apply to specific routes globally, while in-component guards like beforeRouteEnter execute within the component itself; choosing between them depends on whether navigation logic should be centralized or tightly coupled to component lifecycle.

How do I handle param changes in Vue 3 without triggering a full component remount?▼

Handle param changes using onBeforeRouteUpdate or watchers to react to dynamic route updates; this prevents full component remounts by catching navigation updates within the existing component lifecycle.

What's the best way to prevent infinite redirects in Vue Router navigation guards?▼

Prevent infinite redirects in Vue Router navigation guards by adding explicit conditional checks before calling next with a redirect path; this avoids loops when a guard re-triggers the same route.

How do async navigation guards work in Vue Router 4?▼

Vue Router 4 async navigation guards work by resolving promises before completing navigation; failing to resolve or reject properly leaves the navigation hanging indefinitely.

Does this Vue Router guide cover lifecycle edge cases for Vue 3 apps?▼

Yes, this Vue Router guide covers Vue 3 lifecycle edge cases, specifically addressing how in-component guards interact with param changes and navigation pitfalls in Vue Router 4.
