Does it have "onBeforeRouteEnter" in vue composition api?

[JunYen0117]

https://router.vuejs.org/api/functions/onBeforeRouteLeave.html

I can't find "onBeforeRouteEnter" this function in doc API Functions list.
Does it exist?
In Funcions list, we already have
onBeforeRouteLeave()
onBeforeRouteUpdate()

If it exists, would you please add it in doc list?

No. Vue Router does not provide an onBeforeRouteEnter() Composition API function.

beforeRouteEnter runs before navigation is confirmed and before the entering component instance exists. A composable called from that component's setup() would therefore be too late to act as that guard. This is why the Composition API exposes only onBeforeRouteUpdate() and onBeforeRouteLeave().

For enter-time checks, use a route-level guard:

{
  path: '/example',
  component: ExampleView,
  beforeEnter: (to, from) => {
    // return false to cancel, or a route location to redirect
  },
}

A global router.beforeEach() is another option. If you specifically need the post-entry component-instance callback, the Options API beforeRouteEnter(to, from, next) remains the API that supports next(vm => ...).

This lifecycle difference is documented under Navigation Guards.
