How to store page in json?

[alex-eri]

I want to store page attributes outside of MD file and combine data and page types together.

I want to define

---
title: page title
date: 2020-20-20
---

hello
===

world

as something like

{
"title": "page title",
"date": "2020-20-20",
"body": "hello\n===\n\nworld\n"
}

and get content page with toc, navigation, search and etc
