All of vue-router's navigation guards receive the previous route as a from argument ..

Every guard function receives three arguments:

• to: Route: the target Route Object being navigated to.

• from: Route: the current route being navigated away from.

• next: Function: this function must be called to resolve the hook. The action depends on the arguments provided to next

As an example you could use beforeRouteEnter, an in-component navigation guard, to get the previous route and store it in your data ..

...
data() {
 return {
   ...
   prevRoute: null
 }
},
beforeRouteEnter(to, from, next) {
  next(vm => {
    vm.prevRoute = from
  })
},
...

Then you can use this.prevRoute.path to get the previous URL.
