Create Node.js app that is packed with best practices AND strive for simplicity

import isPortReachable from 'is-port-reachable';
import path from 'path';
import dockerCompose from 'docker-compose';
import { execSync } from 'child_process';

export default async () => {
  console.time('global-setup');

  // ️️️✅ Best Practice: Speed up during development, if already live then do nothing
  const isDBReachable = await isPortReachable(54320);
  if (!isDBReachable) {
    // ️️️✅ Best Practice: Start the infrastructure within a test hook - No failures occur because the DB is down
    await dockerCompose.upAll({
      cwd: path.join(__dirname),
      log: true,
    });

    await dockerCompose.exec(
      'database',
      ['sh', '-c', 'until pg_isready ; do sleep 1; done'],
      {
        cwd: path.join(__dirname),
      }
    );

    // ️️️✅ Best Practice: Use npm script for data seeding and migrations
    execSync('npm run db:migrate');
  }

  // 👍🏼 We're ready
  console.timeEnd('global-setup');
