How does vue router handle asynchronous data requests between parents and children?

there is a background management system
routing nesting relationship: app.vue > a.vue > b.vue

I want to do this:
send a request to verify the validity of token in app.vue
send a data request in a / b, and the parameters of the data request depend on the relevant parameters returned by the token validity in app.vue.

question

is this design reasonable, and is it consistent with the original intention of vue"s bucket design?
there will be slow data returns in app.vue, but an and b will send their respective requests out of this asynchronous problem. How to solve this problem?

reasonable. However, this is not a matter for the framework author to consider, not to mention whether it is consistent with the original intention of the design.
you can set a switch in app.vue, such as isLoaded , and then < b VIFF = "isLoaded" > in the template this ensures that app.vue will process an and b

after loading.

does not need to be sent separately to verify the validity of token. token is usually saved after the user logs in, and other subsequent requests are accompanied by this token . The back-end program first verifies the validity of token , which is valid to continue to return corresponding data. If it is not valid, return a status code, and the front end jumps to the login page according to this status code to log in again.
