"Implementing an afterEach handler in vue-router: A step-by-step guide

I need assistance with integrating an afterEach handler into my Vue Router script. Here is the code snippet:

import Vue from 'vue'
import Router from 'vue-router'

Vue.use(Router)

export default new Router({
  scrollBehavior (to, from, savedPosition) {
    // purposely left blank
  },
  routes: [
    {
      path: "/",
      component: SampleComponent
    }
  ]
}

The objective is to have the afterEach handler close any open menus when a router link is clicked. I initially tried adding it directly in the constructor without success.

Subsequently, I attempted the following approach:

Router.afterEach((to, from) => {
  // ...
})

However, this led to an error message:

afterEach is not a function

Could you please provide guidance on how to correctly implement an afterEach callback in this context?

Answer №1

To ensure proper functionality, make sure to assign the afterEach handler to a specific Router instance (which is an object created using the new Router() method).

You should save a reference to your instance and attach the afterEach handler to it before exporting it:

const myRouter = new Router({
  scrollBehavior (to, from, savedPosition) {
    // intentionally left empty
  },
  routes: [
    {
      path: "/",
      component: SampleComponent
    }
  ]
});

myRouter.afterEach((to, from) => {
  // ...
});

export default myRouter
