jsonfile is legacy syntactic sugar.

Bare minimum, that should be more than enough for most of the peeps:

import { readFile, writeFile } from 'node:fs/promises'

const readJson  = f => readFile(f, 'utf8').then(JSON.parse)
const writeJson = (f, x) => writeFile(f, JSON.stringify(x, null, 2) + '\n')

The options are not hard to replace as well.
