Vue Router 4 is in beta and it’s subject to change.

To build a single page app easily, we got to add routing so that URLs will be mapped to components that are rendered.

In this article, we’ll look at how to use Vue Router 4 with Vue 3.

In-Component Guards

The beforeRouteEnter guard is run before the route that renders the component is confirmed

Therefore, it doesn’t have access to this .

However, we can access it within the next callback.

To do that, we write:

beforeRouteEnter(to, from, next) {
  next(vm => {
    // ...

The vm has the route component’s instance.

The is the only route that supports passing in a callback for next .

We can use this directly in the beforeRouterUpdate and beforeRouterLeave methods, so passing in a callback to next isn’t supported.
