[javascript] How can I go back/route-back on vue-router?

Ok, to explain this simply:

I have 3x pages.

• Page 1 (Home)
• Page 2 (Menu)
• Page 3 (About)

Page 1 has a-

<router-link  to="/menu">

button that when clicked routes to "/menu".

For now, Page 2 (Menu) has a

<router-link  to="/">

button and when this button is clicked it reverts to the previous location "/" Page 1 (Home).

But I don't want to create a component for router for each page to 'go back' to the previous page (as if I had 100 pages this could be a lot of work routing back). Is there a way to do this with vue-router? similar to window.history.back()

Curious to see if there is a way to do this as I can't find it in the docs.

Thanks in advance! John

Another solution is using vue-router-back-mixin

import BackMixin from `vue-router-back-mixin`

export default {
  ...
  mixins: [BackMixin],
  methods() {
    goBack() {
      this.backMixin_handleBack()
    }
  }
  ...
}

This works like a clock for me:

methods: {
 hasHistory () { return window.history.length > 2 }
}

Then, in the template:

<button 
  type="button"    
  @click="hasHistory() 
    ? $router.go(-1) 
    : $router.push('/')" class="my-5 btn btn-outline-success">&laquo; 
  Back
</button>

You can use Programmatic Navigation.In order to go back, you use this:

router.go(n) 

Where n can be positive or negative (to go back). This is the same as history.back().So you can have your element like this:

<a @click="$router.go(-1)">back</a>

If you're using Vuex you can use https://github.com/vuejs/vuex-router-sync

Just initialize it in your main file with:

import VuexRouterSync from 'vuex-router-sync';
VuexRouterSync.sync(store, router);

Each route change will update route state object in Vuex. You can next create getter to use the from Object in route state or just use the state (better is to use getters, but it's other story https://vuex.vuejs.org/en/getters.html), so in short it would be (inside components methods/values):

this.$store.state.route.from.fullPath

You can also just place it in <router-link> component:

<router-link :to="{ path: $store.state.route.from.fullPath }"> 
  Back 
</router-link>

So when you use code above, link to previous path would be dynamically generated.

Use router.back() directly to go back/route-back programmatic on vue-router.
