'Change Meta Title and Description using Vue.js

Is it possible to change anything higher than the body tag in Vue.Js? The contents for both these elements is currently stored in the JSON file that is attached to an element further down the DOM tree.

I need to try and inject a meta title and description that can be crawled by Google (ie. It injects, then renders before it gets crawled) and understand the issues with accessing the body element and higher up the DOM tree, as the current Vue JSON is injected using the App ID on a DIV lower down.

I have previously used some jQuery code to address this issue on a Square Space template in some previous work

jQuery('meta[name=description]').attr('content', 'Enter Meta Description Here');

      data: {
        items: []
      },
      created: function () {
        fetch('test.json')
          .then(resp => resp.json())
          .then(items => {
            this.items = items
          })
      }
    });

JSON

  [
    [
    {
        "page1": "Company Name",
        "meta-title": "Acme Corp"
        "meta-desc": "Welcome to Acme Corp"
    }
    ],
    [
    {
        "products": "Product List"
    }
    ],
    [
    {
        "contactus": "Contact Us at Acme Corp"
    }
  ]

Here is the code in action, the incoming JSON file comes in a fixed array format with the meta details alongside the body elements. Making this a bit more tricky.

If you are using Vue Router, I believe that cleaner solution is using beforeEach hook:

const routes = [{ path: '/list', component: List, meta: {title:'List'} }]

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

But it allows you set only static titles.

However, if you are looking for some SEO optimizations, Nuxt will probably solve most of your problems

Vue meta is an NPM package for meta-data management: https://vue-meta.nuxtjs.org/

Example of how I use it in a vue page component:

export default {
name: "Contact",
 metaInfo: function() {
   return {
     title: "My page meta title",
     meta: [
     { name: 'description', content:  "My page meta description" }
    ]
  }
 }

If you use Vue Router(that's what I'm doing) you can set Vue meta here so all your page can use it:

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


Vue.use(Router)
Vue.use(VueMeta)

export default new Router({
mode: 'history',
base: '/',
routes: [
{
  path: '/',
  name: 'Home',
  component: Home
},

If you want to change the title it is easy to change in vuejs.

In router.js file while creating route you can do something like this.

{
    path:"/productdetail",
    name:"productdetail",
    component:ProductDetail,
    meta: {
        title : localStorage.getItem("title"),
    }
    
}

router.beforeEach((toRoute,fromRoute,next) => {
   window.document.title = toRoute.meta.title;
   next();
})

use of localStorage will help you to change title dynamically. unfortunately, meta description is not changing with the same method.
