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');

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.
