[Vuejs]-Specify condition before loading vuejs component

If you need to run this function before every route in your application, you could use router’s beforeEach function to check that.

router.beforeEach((to, from, next) => { }.

If this is only for one or some routes, you could set the property beforeEnter to the route.

In your beforeEach function, you need to make the validation you said you want.

if(this.$store.getters.user.id !== to.params.id) 
   next({
          name: 'home', 
          params: { id: this.$store.getters.user.id }
   });
