Actually you can do this when running gray-matter in Node using the JS parser:

---js
{
  NODE_ENV: process.env.NODE_ENV
}
---

Alternatively you could supply a custom parser engine:

import { javascript } from 'gray-matter/lib/engines.js'

const parsed = matter(str, {
  engines: {
    'embedded-js': (str, options) => {
      // naive implementation but you get the gist
      return javascript.parse(str.replace(/\$/g, 'process.env.'), options)
    }
  }
})

Then use it like so:

---embedded-js
{
  NODE_ENV: $NODE_ENV
}
---

from gray-matter.

I would like to do something similar, accessing environment variables on astro docs front matter.
