vue-router-best-practices

Prevent infinite redirect loops in Vue Router navigation guards by applying meta-based strategies and guard-composition patterns. These practices ensure conditional logic terminates correctly, enforcing auth checks without cycling between protected routes.

Use beforeEnter for route-specific validation in Vue Router 4 by configuring per-route guards. This practice isolates validation logic and redirection handling directly within route definitions, keeping global guards clean.

Handle async data loading with in-component guards like beforeRouteUpdate by managing param changes within the component lifecycle. This practice ensures safe data fetching and resolves navigation only after required asynchronous operations complete.

This Vue Router best practices guide applies directly to Vue 3 SPAs using Vue Router 4. It covers real-world routing scenarios including global beforeEach guards, afterEach error handling, and safe in-component data fetching.

Use global beforeEach guards to enforce application-wide auth and data loading rules. In-component guards like onBeforeRouteUpdate are for handling specific param changes and data interactions within that component's lifecycle.

beforeRouteUpdate fails to trigger data fetching on param changes when the component instance is reused instead of recreated. Implement safe data fetching patterns within the in-component guard to detect and load new data dynamically.
