Navigation guards in Nuxt 3 with defineNuxtRouteMiddleware
- Navigation guards are used to control what features of an application authorized users can access.
- Navigation guards ensure security and improves user experience by keeping your app safe and efficient.
- In Nuxt, middleware are special functions that run before your page is rendered, making it ideal for implementing navigation guards.
- There are three types of middleware in Nuxt: anonymous, named, and global.
- Anonymous middleware is middleware that’s defined inside a page whereas named middleware is defined in a standalone file in the middleware directory, and can be run on multiple pages.
- Global middleware utility should be used sparingly as it runs every time the user accesses any page under its domain.
- Middleware executes in the predefined order as global middleware, and followed by middleware defined in the middleware array of definePageMeta.
- You should write navigation guards as a lean and pure function.
- There is a danger of creating an infinite loop while writing navigation guards if not careful.
- By efficiently implementing navigation guards, you can ensure smooth and effective navigation throughout your app.
