List pending migrations in Node.js using Sequelize ORM (similar to Rails)

app.js

// call this in your app entry file
// Prints:
// ================================================== 
// ABORT: You have pending migrations 
// ================================================== 
// 1. 20200419162657-create_site_settings.js 
//
// Please run `yarn migrate` to run all pending migrations 

export const checkPendingMigrations = () => {
  const commandResult = childProcess.execSync('npx sequelize db:migrate:status');
  const commandResultArray = Buffer.from(commandResult).toString('utf-8').split('\n');
  const pendingMigrations = commandResultArray.filter(line => line.startsWith('down'));

  if (pendingMigrations.length) {
    console.log('='.repeat(50), '\n');
    console.log('ABORT: You have pending migrations', '\n');
    console.log('='.repeat(50), '\n');
    console.log(

    );
