Use Prettier API (Node.js)
const fs = require('fs');
const glob = require('glob');
const prettier = require('prettier');
const path = require('path');
// equivalent to "prettier --ignore-path .gitignore "**/*.{json,md,scss}" --list-different"
const editorConfig = path.join(process.cwd(), '.editorconfig');
const filePattern = '**/*.{json,md,scss}';
const gitIgnore = path.join(process.cwd(), '.gitignore');
