How to programmatically run sequelize migrations

I dug into the code for the sequelize db:migrate command, and there's enough going on there that, IMHO, the simplest/best approach is to just run the command in a child process. Here's the code I used for this (as an await'ed Promise):

const {exec} = require('child_process');

await new Promise((resolve, reject) => {
  const migrate = exec(
    'sequelize db:migrate',
    {env: process.env},
    err => (err ? reject(err): resolve())

  // Forward stdout+stderr to this process
